6 Installing Enterprise Manager System

Overview of the Installation Types

You can install Enterprise Manager Cloud Control with either simple or advanced configuration. Table 6-1 describes the basic differences between the two installation types.

Overview of What Is Installed and Configured

As part of a new Enterprise Manager system, the installation wizard does the following:

• Installs the following components in the Middleware home you enter in the installation wizard:

  • Java Development Kit (JDK) 1.6 v24

  • Oracle WebLogic Server 11g Release 1 (10.3.5)

  • Oracle Management Service 12c Release 2 (12.1.0.2)

  • Oracle JRF 11g Release (11.1.1.6.0), which includes oracle_common directory

  • Oracle Web Tier 11g Release (11.1.1.6.0), which includes Oracle_WT directory

  • Oracle Plug-Ins

    • Oracle Database Plug-In

    • Oracle Fusion Middleware Plug-In

    • Oracle My Oracle Support Plug-In

    • Oracle Exadata Plug-In

      Note:

      • Java Development Kit (JDK) 1.6 v24 and Oracle WebLogic Server 11g Release 1 (10.3.5) are installed only if they do not exist in your environment.

      • If you want to manually install Oracle WebLogic Server 11g Release 1 (10.3.5), then follow the guidelines outlined in Before You Begin.

      • For advanced installation, in addition to the mandatory plug-ins listed above, you can optionally install other plug-ins available in the software kit (DVD, downloaded software). The installer offers a screen where you can select the optional plug-ins and install them. However, if you want to install some plug-ins that are not available in the software kit (DVD, downloaded software), then refer to Advanced Installer Options.

• Installs Oracle Management Agent 12c Release 2 (12.1.0.2) in the agent base directory you specify (outside the Middleware home).

  For example, if the middleware home is /u01/app/Oracle/Middleware/, then you can specify the agent base directory as /u01/app/Oracle/agent12c.

• Creates an Oracle WebLogic domain called GCDomain. For this WebLogic Domain, a default user account, weblogic, is used as the administrative user. In advanced installation, you can choose to change this if you want.

• Creates a Node Manager user account called nodemanager. A Node Manager enables you to start, shut down, or restart an Oracle WebLogic Server instance remotely, and is recommended for applications with high availability requirements.

• Configures an Oracle Management Service Instance Base location (gc_inst) in the Oracle Middleware home (Middleware home), for storing all configuration details related to Oracle Management Service 12c. In advanced installation, you can choose to change this if you want.

  For example, if the Middleware home is /u01/app/Oracle/Middleware/, then the instance base location is /u01/app/Oracle/Middleware/gc_inst. You can choose to change this, if you want, in the installer. However, you can change it for only advanced installation and not for simple installation.

• Configures Oracle Management Repository in the existing, certified Oracle Database. If the database instance is created using the database template offered by Oracle, then this step is skipped.

  Note:

  The existing, certified Oracle Database must be one of the certified databases listed in the Enterprise Manager certification matrix available on My Oracle Support, or a database instance created with a preconfigured Oracle Management Repository (Management Repository) using the database templates offered by Oracle.

  To access the Enterprise Manager certification matrix, follow the steps outlined in Appendix E.

  For information about creating a database instance with a preconfigured Management Repository using the database templates offered by Oracle, refer to Appendix D.

  The database can be on a local or remote host, and if it is on a remote host, it must be monitored by Oracle Management Agent. However, Oracle Real Application Clusters (Oracle RAC) databases must only be on a shared disk.

• Runs the following configuration assistants to configure the installed or upgraded components:

  • Plugins Prerequisites Check Configuration Assistant

  • Repository Configuration Assistant

    Note:

    If you use a database instance that was created with a preconfigured Management Repository using the database templates offered by Oracle, then Repository Out-of-Box Configuration Assistant is run instead of Repository Configuration Assistant.

  • MDS Schema Configuration Assistant

  • OMS Configuration Assistant

  • Plugins Deployment and Configuration Assistant

  • Start Oracle Management Service Configuration Assistant

  • Oracle Configuration Manager for OMS Configuration Assistant

  • Agent Configuration Assistant

Installing with Simple Configuration

To install Enterprise Manager Cloud Control with simple configuration, follow these steps:

1. Invoke the Enterprise Manager Cloud Control Installation Wizard.

   Invoke the installation wizard as a user who belongs to the oinstall group you created following the instructions in Chapter 4.

   <Software_Location>/runInstaller

   In this command, <Software_Location> is either the DVD location or the location where you have downloaded the software kit.

   Note:

   • To invoke the installation wizard on UNIX platforms, run runInstaller. To invoke on Microsoft Windows platforms, run setup.exe.

   • Ensure that there are no white spaces in the name of the directory where you download and run the Enterprise Manager Cloud Control software from. For example, do not download and run the software from a directory titled EM Software because there is a white space between the two words of the directory name.

   • When you invoke runInstaller or setup.exe, if the Enterprise Manager Cloud Control Installation Wizard does not appear, then it is possible that you do not have read and write access to the /stage subdirectory, which a subdirectory in the Disk1 directory of the Enterprise Manager software.

     There is a classpath variable that the installation wizard computes for OPatch as ../stage/Components/, and when the TEMP variable is set to /tmp, the installation wizard tries to look for the opatch JAR file in the /tmp/../stage directory, which is equivalent to /stage. However, if you do not have read and write permission on /stage, then the installation wizard can hang. Under such circumstances, verify if you have read and write access to the /stage directory. If you do not have, then set the TEMP variable to a location where the install user has access to, and then relaunch the installation wizard.

2. Enter My Oracle Support Details.

   
   

   (Optional) On the My Oracle Support Details screen, enter your My Oracle Support credentials to enable Oracle Configuration Manager. If you do not want to enable Oracle Configuration Manager now, go to Step (3).

   If the host from where you are running the installation wizard does not have a connection to the Internet, then enter only the e-mail address and leave the other fields blank. After you complete the installation, manually collect the configuration information and upload it to My Oracle Support.

3. Click Next.

4. Install Software Updates.

   
   

   On the Software Updates screen, select one of the following sources from where the software updates can be installed while the installation of the Enterprise Manager system is in progress. If you do not want to apply them now, then select Skip.

   • (Recommended) Select Search for Updates, then select Local Directory if you have already manually downloaded the software updates to an accessible local or remote location.

     Note:

     For instructions to manually download the software updates, refer to Oracle Enterprise Manager Cloud Control Advanced Installation and Configuration Guide.

     Enter the location where the updates are available, and click Search for Updates. To search the computer and select the location, click Browse. Once the search results appear with patch numbers and their details, click the patch number to view the ReadMe associated with that patch.

     • If the updates have been downloaded to the default location, then select or enter the full path to the scratch path location. For example, if the scratch path location is /scratch/OracleHomes and if the software updates are available in /scratch/OracleHomes/Updates, then enter /scratch/OracleHomes/Updates.

     • If the software updates have been downloaded to a custom location, then select or enter the full path to the custom location. For example, if the custom location is /home/john and if the software updates are available in /home/john/Updates, then enter /home/john/Updates.

   • Select Search for Updates, then select My Oracle Support if you want the installer to connect to My Oracle Support and automatically download the updates from there.

     Enter the My Oracle Support account user name and password, and click Search for Updates. Once the search results appear with patch numbers and their details, click the patch number to view the ReadMe associated with that patch

   Note:

   Despite providing the My Oracle Support credentials, if you are unable to download the software updates, then exit the installer, and invoke the installer again passing the -showProxy parameter in the following way:

   <Software_Location>/runInstaller -showProxy

   Note:

   If you choose to skip installing the software updates during installation by not providing the My Oracle Support credentials, you can always register the credentials later using the Enterprise Manager Cloud Control console and view the recommended security patches. To do so, log in to Enterprise Manager Cloud Control, and from the Setup menu, select My Oracle Support, then click Set Credentials. On the My Oracle Support Preferred Credentials page, enter the credentials and click Apply.

5. Click Next.

   If Enterprise Manager Cloud Control is the first Oracle product you are installing on the host that is running on UNIX operating system, then the Oracle Inventory screen appears. For details, see step (6). Otherwise, the Check Prerequisites screen appears. For details, see step (8).

   If Enterprise Manager Cloud Control is the first Oracle product you are installing on the host that is running on Microsoft Windows operating system, then the Oracle Inventory screen does not appear. On Microsoft Windows, the following is the default inventory directory:

   <system drive>\Program Files\Oracle\Inventory
   

6. Enter Oracle Inventory Details.

   On the Oracle Inventory screen, do the following. You will see this screen only if this turns out to be your first ever installation of an Oracle product on the host.

   1. Enter the full path to a directory where the inventory files and directories can be placed.

      Note:

      • The central inventory location you enter must NOT be on a shared file system. If it is already on a shared file system, then switch over to a non-shared file system by following the instructions outlined in My Oracle Support note 1092645.1

      • If this is the first Oracle product on the host, then the default central inventory location is <home directory>/oraInventory. However, if you already have some Oracle products on the host, then the central inventory location can be found in the oraInst.loc file. The oraInst.loc file is located in the /etc directory for Linux and AIX, and in the /var/opt/oracle directory for Solaris, HP-UX, and Tru64.

   2. Select the appropriate operating system group name that will own the Oracle inventory directories. The group that you select must have write permissions on the Oracle Inventory directories.

7. Click Next.

8. Check Prerequisites.

   
   

   On the Prerequisite Checks screen, check the status of the prerequisite checks run by the installation wizard, and verify whether your environment meets all the minimum requirements for a successful installation.

   The installation wizard runs the prerequisite checks automatically when you come to this screen. It checks for the required operating system patches, operating system packages, and so on.

   The status of the prerequisite check can be either Warning, Failed, or Succeeded.

   • If some checks result in Warning or Failed status, then investigate and correct the problems before you proceed with the installation. The screen provides details on why the prerequisites failed and how you can resolve them. After you correct the problems, return to this screen and click Rerun to check the prerequisites again.

   • However, all package requirements must be met or fixed before proceeding any further. Otherwise, the installation might fail.

9. Click Next.

10. Select Installation Type.

    
    

    On the Installation Types screen, select Create a New Enterprise Manager System, then select Simple.

11. Click Next.

12. Enter Installation Details.

    
    

    On the Installation Details screen, do the following:

    1. Enter or validate the Middleware home where you want to install the OMS and other core components.

       Note:

       • If you have Oracle WebLogic Server and Java Development Kit already installed, then ensure that they are of the supported releases—Oracle WebLogic Server 11g Release 1 (10.3.5) and JDK 1.6 v24+. If you have the supported releases, the installer automatically detects them and displays the absolute path to the Middleware home where they are installed. In this case, validate the Middleware home. If the location is incorrect, then enter the path to the correct location. Ensure that the Middleware home you select or enter is a Middleware home that does not have any Oracle homes for Oracle Management Service and Oracle Management Agent.

       • If you do not have Oracle WebLogic Server 11g Release 1 (10.3.5) and JDK 1.6 v24+, then the installer automatically installs them for you while installing the Enterprise Manager system. In this case, enter the absolute path to a directory where you want to have them installed. For example, /oracle/software/. Ensure that the directory you enter does not contain any files or subdirectories.

       • If you want to manually install Oracle WebLogic Server 11g Release 1 (10.3.5), then follow the guidelines outlined in Before You Begin.

       • (Only for Microsoft Windows) Ensure that the number of characters in the middleware home path does not exceed 25 characters.

         For example, the middleware home path C:\Oracle\MW\EM containing only 15 characters is acceptable. However, C:\Oracle\MW\new\EM\dir\a123 containing more than 25 characters is not acceptable.

    2. Enter the absolute path to the agent base directory, a location outside the Oracle Middleware home where the Management Agent can be installed. For example, /oracle/agent. Ensure that this location is empty and has write permission. Also ensure that it is always maintained outside the Oracle Middleware home.

       Note:

       (Only for Microsoft Windows) Ensure that the number of characters in the agent base directory path does not exceed 25 characters.

       For example, the agent base directory path C:\Oracle\Agent\ containing only 16 characters is acceptable. However, C:\Oracle\ManagementAgent\12c\new containing more than 25 characters is not acceptable.

    3. Validate the name of the host where you want to configure the OMS.

       The host name appears as a fully qualified name. The host name can also appear as a virtual host name if your host is configured with virtual machine.

       You can choose to accept the default host name and proceed with the installation. Alternatively, you can change the name if it is incorrect, or enter another host name for this host. Ensure that the host name you enter is accessible from other hosts in the network (other hosts must be able to ping this host).

13. Click Next.

14. Enter Configuration Details.

    
    

    On the Configuration Details screen, do the following:

    1. Enter an administrator password, which can be used as a common password for configuring the Enterprise Manager Cloud Control.

       Note:

       Ensure that your password contains at least 8 characters without any spaces, begins with a letter, and includes at least one numeric value.

       Table 6-3 describes what the administrator password is used for.

       Table 6-3 Usage of Administrator Password

       Purpose	Description
       Creates SYSMAN User Account	The user account is used as the super administrator for configuring the SYSMAN schema in the Management Repository.
       Creates Default WebLogic User Account weblogic	The user account is used as the administrator for creating the default WebLogic domain GCDomain.
       Creates Default Node Manager User Account nodemanager	The user account is automatically created during the configuration of Enterprise Manager Cloud Control. A Node Manager enables you to start, shut down, or restart an Oracle WebLogic Server instance remotely, and is recommended for applications with high availability requirements.
       Authenticates New Management Agents	The agent registration password is used for authenticating new Management Agents that join Enterprise Manager system, where the communication between the OMS and the Management Agent is secure.

       
       

    2. Provide details of the existing, certified database where the Management Repository needs to be created. If you have already created a database instance with a preconfigured Management Repository using the database templates offered by Oracle, then provide details about that database instance.

       The installer uses this information to connect to the existing database for creating the SYSMAN schema and plug-in schemas. If you provide details of a database that already has a preconfigured Management Repository, then the installer only creates plug-in schemas.

       Note:

       • For information about creating a database instance with a preconfigured Management Repository using the database templates offered by Oracle, refer to Appendix D.

       • If you connect to a database instance that was created using the database template offered by Oracle, then the password assigned to user accounts SYSMAN, SYSMAN_MDS, SYSMAN_APM, and SYSMAN_OPSS, which were created while preconfiguring the Management Repository, are automatically reset with the administrator password you enter here on this screen. We also unlock all these user accounts.

       • To identify whether your database is a certified database listed in the certification matrix, follow the steps outlined in Appendix E.

       • Oracle Real Application Cluster (Oracle RAC) nodes are referred to by their virtual IP (vip) names. The service_name parameter is used instead of the system identifier (SID) in connect_data mode, and failover is turned on. For more information, refer to Oracle Database Net Services Administrator's Guide.

       • If any repository-related prerequisite check fails, see Appendix A to manually run the prerequisite check.

15. Click Next.

    Note:

    • If you are connecting to an Oracle RAC database, and if you have specified the virtual IP address of one of its nodes, then the installation wizard prompts you with a Connection String dialog and requests you to update the connection string with information about the other nodes that are part of the cluster. Update the connection string and click OK. If you want to test the connection, click Test Connection.

    • If your Oracle RAC database is configured with Single Client Access Name (SCAN) listener, then you can enter a connection string using the SCAN listener.

    • Oracle Real Application Cluster (Oracle RAC) nodes are referred to by their virtual IP (vip) names. The service_name parameter is used instead of the system identifier (SID) in connect_data mode, and failover is turned on. For more information, refer to Oracle Database Net Services Administrator's Guide.

    • If you see an error stating that the connection to the database failed with ORA-01017 invalid user name/password, then follow these steps to resolve the issue:

      (1) Verify that SYS password provided is valid.

      (2) Verify that the database initialization parameter REMOTE_LOGIN_PASSWORDFILE is set to Shared or Exclusive.

      (3) Verify that password file with the file name orapw<SID> exists in the <ORACLE_HOME>/dbs directory of the database home. If it does not, create a password file using the ORAPWD command.

16. Review and Install

    On the Review screen, review the details you provided for the selected installation type.

    • If you want to change the details, click Back repeatedly until you reach the screen where you want to make the changes.

    • After you verify the details, if you are satisfied, click Install to begin the installation process.

17. Track the Progress

    On the Install Progress screen, view the overall progress (in percentage) of the installation and the status of each of the configuration assistants. Configuration assistants are run for configuring the installed components of Enterprise Manager Cloud Control.

    Note:

    • If a configuration assistant fails, the installer stops and none of the subsequent configuration assistants are run. Resolve the issue and retry the configuration assistant.

      For more information, see the appendix on troubleshooting tips in the Oracle Enterprise Manager Cloud Control Advanced Installation and Configuration Guide.

    • If you accidently exit the installer before clicking Retry, then do NOT restart the installer to reach the same screen; instead, invoke the runConfig.sh script from the OMS home to rerun the Configuration Assistant in silent mode. For Microsoft Windows platforms, invoke runConfig.bat script.

      $<OMS_HOME>/oui/bin/runConfig.sh ORACLE_HOME=<absolute_path_to_OMS_home> MODE=perform ACTION=configure COMPONENT_XML={encap_oms.1_0_0_0_0.xml}

      If the runConfig.sh script fails, then clean up your environment and redo the installation.

18. Run Scripts

    Once the software binaries are copied and configured, you are prompted to run the allroot.sh script, and the oraInstRoot.sh script if this is the first Oracle product installation on the host. Open another window, log in as root, and manually run the scripts.

    If you are installing on Microsoft Windows operating system, then you will NOT be prompted to run this script.

19. End the Installation

    On the Finish screen, you should see information pertaining to the installation of Enterprise Manager. Review the information and click Close to exit the installation wizard.

    For more information about this installation, refer to the following file in the OMS home:

    $<OMS_HOME>/install/setupinfo.txt

       You can choose to accept the default host name and proceed with the installation. Alternatively, you can change the name if it is incorrect, or enter another host name for this host. Ensure that the host name you enter is accessible from other hosts in the network (other hosts must be able to ping this host).

13. Click Next.

14. Deploy Plug-Ins.

    
    

    On the Plug-In Deployment screen, select the optional plug-ins you want to install from the software kit (DVD, downloaded software) while installing the Enterprise Manager system.

    The pre-selected rows are mandatory plug-ins that will be installed by default. Select the optional ones you want to install.

    Note:

    During installation, if you want to install a plug-in that is not available in the software kit, then refer to Advanced Installer Options for the point that describes how you can install additional plug-ins.

15. Click Next.

16. Enter WebLogic Server Configuration Details.

    
    

    On the WebLogic Server Configuration Details screen, enter the credentials for the WebLogic Server user account and the Node Manager user account, and validate the path to the Oracle Management Service instance base location.

    Note:

    Ensure that your password contains at least 8 characters without any spaces, begins with a letter, and includes at least one numeric value.

    By default, the WebLogic Domain name is GCDomain, and the Node Manager name is nodemanager. These are non-editable fields. The installer uses this information for creating Oracle WebLogic Domain and other associated components such as the admin server, the managed server, and the node manager. A Node Manager enables you to start, shut down, or restart an Oracle WebLogic Server instance remotely, and is recommended for applications with high availability requirements.

    Note:

    If you are installing in an NFS-mounted location, and if you see an error message prompting you not to enter an NFS-mounted location for the OMS instance base location, then click Back repeatedly to reach the Software Updates screen. On the Software Updates screen, select an appropriate option to search and apply the patch 14145094. For more information, click Help on that screen.

    The patch converts the error message to a warning that you can ignore. The installer exits automatically, applies the patch, and invokes itself again for you to proceed with the installation. Once the installation ends, move the lock file location from the NFS-mounted location to a local file system location. Modify the lock file location in the httpd.conf file to map to the location on the local file system. For instructions, refer to After You Install.

17. Click Next.

18. Enter Database Connection Details.

    
    

    On the Database Connection Details screen, do the following:

    1. Provide details of the existing, certified database where the Management Repository needs to be created. If you have already created a database instance with a preconfigured Management Repository using the database templates offered by Oracle, then provide details about that database instance.

       The installer uses this information to connect to the existing database for creating the SYSMAN schema and plug-in schemas. If you provide details of a database that already has a preconfigured Management Repository, then the installer only creates plug-in schemas.

       Note:

       • If you connect to a database instance that was created using the database template offered by Oracle, then note that the password assigned to the user accounts SYSMAN_MDS, SYSMAN_APM, and SYSMAN_OPSS, which were created while preconfiguring the Management Repository, are automatically reset with the SYSMAN password you enter on the Repository Configuration Details screen (as described in Step (20)).

       • Oracle Real Application Cluster (Oracle RAC) nodes are referred to by their virtual IP (vip) names. The service_name parameter is used instead of the system identifier (SID) in connect_data mode, and failover is turned on. For more information, refer to Oracle Database Net Services Administrator's Guide.

    2. Select the deployment size from the Deployment Size list to indicate the number of targets you plan to monitor, the number Management Agents you plan to have, and the number of concurrent user sessions you plan have.

       Table 6-4 describes each deployment size.

       Table 6-4 Deployment Size

       Deployment Size	Targets Count	Management Agents Count	Concurrent User Session Count
       Small	Up to 999	Up to 99	Up to 10
       Medium	Between 1000 and 9999	Between 100 and 999	Between 10 and 24
       Large	10,000 or more	1000 or more	Between 25 and 50

       
       

       For more information on deployment sizes, the prerequisite checks that are run, the database parameters that are set, and how you can modify the deployment size after installation, refer to Oracle Enterprise Manager Cloud Control Advanced Installation and Configuration Guide.

19. Click Next.

    Note:

    • If you connect to a database instance that was created using the database template offered by Oracle, then you will be prompted that the database parameters need to be modified to suit the deployment size you selected. This is because the templates are essentially designed for simple installation, and the database parameters are set as required for simple installation. Since it is used for advanced installation, the parameters must be set to different values. You can confirm the message to proceed further. The installation wizard will automatically set the parameters to the required values.

    • If you are connecting to an Oracle RAC database, and if you have specified the virtual IP address of one of its nodes, then the installation wizard prompts you with a Connection String dialog and requests you to update the connection string with information about the other nodes that are part of the cluster. Update the connection string and click OK. If you want to test the connection, click Test Connection.

    • If your Oracle RAC database is configured with Single Client Access Name (SCAN) listener, then you can enter a connection string using the SCAN listener.

    • Oracle Real Application Cluster (Oracle RAC) nodes are referred to by their virtual IP (vip) names. The service_name parameter is used instead of the system identifier (SID) in connect_data mode, and failover is turned on. For more information, refer to Oracle Database Net Services Administrator's Guide

    • If you see an error stating that the connection to the database failed with ORA-01017 invalid user name/password, then follow these steps to resolve the issue:

      (1) Verify that SYS password provided is valid.

      (2) Verify that the database initialization parameter REMOTE_LOGIN_PASSWORDFILE is set to Shared or Exclusive.

      (3) Verify that password file with the file name orapw<SID> exists in the <ORACLE_HOME>/dbs directory of the database home. If it does not, create a password file using the ORAPWD command.

20. Enter Repository Configuration Details

    
    

    On the Repository Configuration Details screen, do the following:

    1. For SYSMAN Password, enter a password for creating the SYSMAN user account. The SYSMAN user account is used for creating the SYSMAN schema, which holds most of the relational data used in managing Enterprise Manager Cloud Control. SYSMAN is also the super administrator for Enterprise Manager Cloud Control.

       Note:

       • Ensure that your password contains at least 8 characters without any spaces, begins with a letter, and includes at least one numeric value.

       • If you connect to a database instance that was created using the database template offered by Oracle, then note that the password assigned to the user accounts SYSMAN_MDS, SYSMAN_APM, and SYSMAN_OPSS, which were created while preconfiguring the Management Repository, are automatically reset with the SYSMAN password you enter on this screen.

    2. For Registration Password, enter a password for registering the new Management Agents that join the Enterprise Manager system.

       Note:

       Ensure that your password contains at least 8 characters without any spaces, begins with a letter, and includes at least one numeric value.

    3. For Management Tablespace, enter the full path to the location where the data file for management tablespace (mgmt.dbf) can be stored. The installer uses this information for storing data about the monitored targets, their metrics, and so on. Ensure that the specified path leads up to the file name.

       For example, /u01/oracle/prod/oradata/mgmt.dbf

    4. For Configuration Data Tablespace, enter the full path to the location where the data file for configuration data tablespace (mgmt_ecm_depot1.dbf) can be stored. This is required for storing configuration information collected from the monitored targets. Ensure that the specified path leads up to the file name.

       For example, /u01/oracle/prod/oradata/mgmt_ecm_depot1.dbf

    5. For JVM Diagnostics Data Tablespace, enter the full path to a location where the data file for JVM Diagnostics data tablespace (mgmt_ad4j.dbf) can be stored. Ensure that the specified path leads up to the file name. Enterprise Manager Cloud Control requires this data file to store monitoring data related to JVM Diagnostics and Application Dependency Performance (ADP).

       For example, /u01/oracle/prod/oradata/mgmt_ad4j.dbf

    Note:

    If you are configuring the Management Repository on a database that uses Oracle Automatic Storage Management (Oracle ASM) for storage, then when you enter the data file location, only the disk group is used for creating the tablespaces. For example, if you specify +DATA/a.dbf, then only +DATA is used for creating the tablespaces on Oracle ASM, and the exact location of the data file on the disk group is decided by Oracle Managed Files.

21. Click Next.

22. Customize Ports

    
    

    On the Port Configuration Details screen, customize the ports to be used for various components.

    Note:

    If all the ports on this screen appear as -1, then it indicates that the installer is unable to bind the ports on the host. To resolve this issue, exit the installer, verify the host name and the IP configuration of this host (ensure that the IP address of the host is not being used by another host), restart the installer, and try again.

    You can enter a free custom port that is either within or outside the port range recommended by Oracle.

    To verify if a port is free, run the following command:

    • On Unix:

      netstat -an | grep <port no>

    • On Microsoft Windows:

      netstat -an|findstr <port_no>

    However, the custom port must be greater than 1024 and lesser than 65535. Alternatively, if you already have the ports predefined in a staticports.ini file and if you want to use those ports, then click Import staticports.ini File and select the file.

    Note:

    If the staticports.ini file is passed during installation, then by default, the ports defined in the staticports.ini file are displayed. Otherwise, the first available port from the recommended range is displayed.

    The staticports.ini file is available in the following location:

    <Software_Extracted_Location>/response

23. Click Next.

24. Review and Install

    On the Review screen, review the details you provided for the selected installation type.

    • If you want to change the details, click Back repeatedly until you reach the screen where you want to make the changes.

    • After you verify the details, if you are satisfied, click Install to begin the installation process.

25. Track the Progress

    On the Install Progress screen, view the overall progress (in percentage) of the installation and the status of each of the Configuration Assistants. Configuration Assistants are run for configuring the installed components of Enterprise Manager Cloud Control.

    Note:

    • If a configuration assistant fails, the installer stops and none of the subsequent configuration assistants are run. Resolve the issue and retry the configuration assistant.

      For more information, see the appendix on troubleshooting tips in the Oracle Enterprise Manager Cloud Control Advanced Installation and Configuration Guide.

    • If you accidently exit the installer before clicking Retry, then do NOT restart the installer to reach the same screen; instead, invoke the runConfig.sh script from the OMS home to rerun the Configuration Assistant in silent mode. For Microsoft Windows platforms, invoke runConfig.bat script.

      $<OMS_HOME>/oui/bin/runConfig.sh ORACLE_HOME=<absolute_path_to_OMS_home> MODE=perform ACTION=configure COMPONENT_XML={encap_oms.1_0_0_0_0.xml}

      If the runConfig.sh script fails, then clean up your environment and redo the installation.

26. Run Scripts

    Once the software binaries are copied and configured, you are prompted to run the allroot.sh script, and the oraInstRoot.sh script if this is the first Oracle product installation on the host. Open another window, log in as root, and manually run the scripts.

    If you are installing on Microsoft Windows operating system, then you will NOT be prompted to run this script. You will directly reach the Finish screen as described in Step (27).

27. End the Installation

    On the Finish screen, you should see information pertaining to the installation of Enterprise Manager. Review the information and click Close to exit the installation wizard.

    For more information about this installation, refer to the following file available in the OMS home:

    $<OMS_HOME>/install/setupinfo.txt
