4 Oracle Fusion Middleware Administration

4.1.1 Clarification About Path for OPMN

OPMN provides the opmnctl command. The executable file is located in the following directories:

• ORACLE_HOME/opmn/bin/opmnctl: The opmnctl command from this location should be used only to create an Oracle instance or a component for an Oracle instance on the local system. Any opmnctl commands generated from this location should not be used to manage system processes or to start OPMN.

  On Windows, if you start OPMN using the opmnctl start command from this location, OPMN and its processes will terminate when the Windows user has logged out.

• ORACLE_INSTANCE/bin/opmnctl: The opmnctl command from this location provides a per Oracle instance instantiation of opmnctl. Use opmnctl commands from this location to manage processes for this Oracle instance. You can also use this opmnctl to create components for the Oracle instance.

  On Windows, if you start OPMN using the opmnctl start command from this location, it starts OPMN as a Windows service. As a result, the OPMN parent process, and the processes which it manages, persist after the MS Windows user has logged out.

4.1.2 Fusion Middleware Control May Return Error in Mixed IPv6 and IPv4 Environment

If your environment contains both IPv6 and IPv4 network protocols, Fusion Middleware Control may return an error in certain circumstances.

If the browser that is accessing Fusion Middleware Control is on a host using the IPv4 protocol, and selects a control that accesses a host using the IPv6 protocol, Fusion Middleware Control will return an error. Similarly, if the browser that is accessing Fusion Middleware Control is on a host using the IPv6 protocol, and selects a control that accesses a host using the IPv4 protocol, Fusion Middleware Control will return an error.

For example, if you are using a browser that is on a host using the IPv4 protocol and you are using Fusion Middleware Control, Fusion Middleware Control returns an error when you navigate to an entity that is running on a host using the IPv6 protocol, such as in the following situations:

• From the Oracle Internet Directory home page, you select Directory Services Manager from the Oracle Internet Directory menu. Oracle Directory Services Manager is running on a host using the IPv6 protocol.

• From a Managed Server home page, you click the link for Oracle WebLogic Server Administration Console, which is running on IPv6.

• You test Web Services endpoints, which are on a host using IPv6.

• You click an application URL or Java application which is on a host using IPv6.

To work around this issue, you can add the following entry to the /etc/hosts file:

nnn.nn.nn.nn  myserver-ipv6 myserver-ipv6.example.com

In the example, nnn.nn.nn.nn is the IPv4 address of the Administration Server host, myserver.example.com.

4.1.3 Deploying JSF Applications

Some JSF applications may experience a memory leak due to incorrect Abstract Window Toolkit (AWT) application context classloader initialization in the Java class library. Setting the oracle.jrf.EnableAppContextInit system property to true will attempt eager initialization of the AWT application context classloader to prevent this leak from occurring. By default, this property is set to false.

4.1.4 Limitations in Moving from Test to Production

Note the following limitations in moving from test to production:

• If your environment includes Oracle WebLogic Server which you have upgraded from one release to another (for example from 10.3.4 to 10.3.5), the pasteConfig scripts fails with the following error:

  Oracle_common_home/bin/unpack.sh line29:
  WL_home/common/bin/unpack.sh No such file or directory
  

  To work around this issue, edit the following file:

  MW_HOME/utils/uninstall/WebLogic_Platform_10.3.5.0/WebLogic_Server_10.3.5.0_Core_Application_Server.txt file
  

  Add the following entries:

  /wlserver_10.3/server/lib/unix/nodemanager.sh
  /wlserver_10.3/common/quickstart/quickstart.cmd
  /wlserver_10.3/common/quickstart/quickstart.sh
  /wlserver_10.3/uninstall/uninstall.cmd
  /wlserver_10.3/uninstall/uninstall.sh
  /utils/config/10.3/setHomeDirs.cmd
  /utils/config/10.3/setHomeDirs.sh
  

• When you are cloning Oracle Virtual Directory, the Oracle instance name in the source environment cannot be the same as the Oracle instance name in the target environment. The Oracle instance name in the target must be different than the name in the source.

• After you clone Oracle Virtual Directory from one host to another, you must add a self-signed certificate to the Oracle Virtual Directory keystore and EM Agent wallet on Host B. Take the following steps:

  1. Set the ORACLE_HOME and JAVA_HOME environment variables.

  2. Delete the existing self-signed certificate:

     $JAVA_HOME/bin/keytool -delete -alias serverselfsigned
       -keystore ORACLE_INSTANCE/config/OVD/ovd_component_name/keystores/keys.jks
       -storepass OVD_Admin_password 
     

  3. Generate a key pair:

     $JAVA_HOME/bin/keytool -genkeypair
       -keystore ORACLE_INSTANCE/config/OVD/ovd_component_name/keystores/keys.jks
       -storepass OVD_Admin_password -keypass OVD_Admin_password -alias serverselfsigned
       -keyalg rsa -dname "CN=Fully_qualified_hostname,O=test" 
     

  4. Export the certificate:

     $JAVA_HOME/bin/keytool -exportcert
       -keystore ORACLE_INSTANCE/config/OVD/ovd_component_name/keystores/keys.jks
       -storepass OVD_Admin_password -rfc -alias serverselfsigned
       -file ORACLE_INSTANCE/config/OVD/ovd_component_name/keystores/ovdcert.txt 
     

  5. Add a wallet to the EM Agent:

     ORACLE_HOME/../oracle_common/bin/orapki wallet add
       -wallet ORACLE_INSTANCE/EMAGENT/EMAGENT/sysman/config/monwallet
       -pwd EM_Agent_Wallet_password -trusted_cert
       -cert ORACLE_INSTANCE/config/OVD/ovd_component_name/keystores/ovdcert.txt 
     

  6. Stop and start the Oracle Virtual Directory server.

  7. Stop and start the EM Agent.

• The copyConfig operation fails if you are using IPv6 and the Managed Server listen address is not set.

  To work around this problem, set the Listen Address for the Managed Server in the Oracle WebLogic Server Administration Console. Navigate to the server. Then, on the Settings for server page, enter the Listen Address. Restart the Managed Servers.

• When you are moving Oracle Platform Security and you are using an LDAP store, the LDAP store on the source environment must be running and it must be acccessible from the target during the pasteConfig operation.

4.1.5 Limitations in Moving Oracle Business Process Management from Test to Production Environment

Note the following limitations when moving Oracle Business Process Management from a test environment to a production environment:

• When you move Oracle Business Process Management from a test environment to a production environment as described in the Task "Move Oracle Business Process Management to the New Production Environment" in the Oracle Fusion Middleware Administrator's Guide, Oracle Business Process Management Organization Units are not imported.

  To work around this issue, you must re-create the Organization Units in the production environment. In addition, if any Organization associations with the Calendar rule for the Role exist in the test environment, you must re-create them, using the Roles screen.

  For information, see "Working with Organizations" in the Oracle Fusion Middleware Modeling and Implementation Guide for Oracle Business Process Management.

• Oracle recommends that you move artifacts and data into a new, empty production environment. If the same artifacts are present or some data has been updated on the production environment, the procedure does not update those artifacts.

• If Oracle Service Bus is part of the same domain as Oracle SOA Suite, you cannot use the test-to-production procedures described in "Moving Oracle SOA Suite to a Production Environment" in the Oracle Fusion Middleware Administrator's Guide. you can either install Oracle Service Bus in a different domain, or manually create the production environment.

4.1.6 Message Returned with Incorrect Error Message Level

In Fusion Middleware Control, when you select a metadata repository, the following error messages are logged:

Partitions is NULL
Partitions size is 0 

These messages are logged at the Error level, which is incorrect. They should be logged at the debug level, to provide information.

4.2.1 Must Stop Oracle SOA Suite Managed Server Before Stopping soa-infra

Using Fusion Middleware Control, if you stop a Oracle SOA Suite Managed Server before you stop soa-infra, then you start the Managed Server, the soa-infra application is not restarted automatically. If you try to restart the soa-infra, you will received an error. When you encounter the problem, you cannot close the dialog box in the browser, so you cannot take any further actions in Fusion Middleware Control.

To avoid this situation, you should stop the Managed Server, which stops all applications, including the soa-infra application. To start the Managed Server and the soa-infra, start the Managed Server.

To close the browser dialog box, enter the following URL in your browser:

http://host:port/em

4.2.2 Configuring Fusion Middleware Control for Windows Native Authentication

To use Windows Native Authentication (WNA) as the single sign-on mechanism between Fusion Middleware Control and Oracle WebLogic Server Administration Console, you must make changes to the following files:

• web.xml

• weblogic.xml

These files are located in the em.ear file. You must explode the em.ear file, edit the files, then rearchive the em.ear file. Take the following steps (which assume that while the front end is on Windows, the em.ear file is on UNIX):

1. Set the JAVA_HOME environment variable. For example:

   setenv JAVA_HOME /scratch/Oracle/Middleware/jrockit_160_05_R27.6.2-20 
   

2. Change to the directory containing the em.ear, and explode the file. For example:

   cd /scratch/Oracle/Middleware/user_projects/applications/domain_name
   JAVA_HOME/bin/jar xvf em.ear em.war 
   JAVA_HOME/bin/jar xvf em.war WEB-INF/web.xml
   JAVA_HOME/bin/jar xvf em.war WEB-INF/weblogic.xml
   

3. Edit web.xml, commenting out the first login-config block and uncommenting the login-config block for WNA. (The file contains information about which block to comment and uncomment.) When you have done this, the portion of the file will appear as in the following example:

   <!--<login-config>
        <auth-method>CLIENT-CERT</auth-method>
      </login-config>
   -->  
    <!--
     the following block is for Windows Native Authentication, if you are using
    WNA, do the following:
       1. uncomment the following block
       2. comment out the previous <login-config> section.
       3. you also need to uncomment a block in weblogic.xml
    -->
      <login-config>
        <auth-method>CLIENT-CERT,FORM</auth-method>
        <form-login-config>
          <form-login-page>/faces/targetauth/emasLogin</form-login-page>
          <form-error-page>/login/LoginError.jsp</form-error-page>
        </form-login-config>
      </login-config>
      <security-constraint>
    .
    .
    .
      <security-role>
        <role-name>Monitor</role-name>
      </security-role>
    
   

4. Edit weblogic.xml, uncommenting the following block. (The file contains information about which block to uncomment.) When you have done this, the portion of the file will appear as in the following example:

   <!--
    the following block is for Windows Native Authentication, if you are using
    WNA, uncomment the following block.
    -->
     <security-role-assignment>
        <role-name>Admin</role-name>
        <externally-defined/>
      </security-role-assignment>
    .
    .
    .
      <security-role-assignment>
        <role-name>Deployer</role-name>
        <externally-defined/>
      </security-role-assignment>
   

5. Rearchive the em.ear file. For example:

   JAVA_HOME/bin/jar uvf em.war WEB-INF/web.xml
   JAVA_HOME/bin/jar uvf em.war WEB-INF/weblogic.xml
   JAVA_HOME/bin/jar uvf em.ear em.war 
   

4.2.3 Fusion Middleware Control Does Not Keep Column Preferences in Log Viewer Pages

In Fusion Middleware Control, you can reorder the columns in the pages that display log files and log file messages. However, if you navigate away from the page and then back to it, the columns are set to their original order.

4.2.4 Topology Viewer Does Not Display Applications Deployed to a Cluster

In Fusion Middleware Control, the Topology Viewer does not display applications that are deployed to a cluster.

4.2.5 Changing Log File Format

When you change the log file format note the following:

• When you change the log file format from text to xml, specify the path, but omit the file name. The new file will be named log. xml.

• When you change the log file format from xml to text, specify both the path and the file name.

4.2.6 SSL Automation Tool Configuration Issues

The following issues have been observed when using the SSL Automation tool:

• The script creates intermediate files that contain passwords in clear text. If the script fails, these files might not be removed. After a script failure, delete all files under the rootCA directory.

• If Oracle Internet Directory password policy is enabled, passwords entered for wallet or keystore fail if they violate the policy.

• Before you run the script, you must have JDK 1.6 installed and you must have JAVA_HOME set in your environment.

• If the Oracle Virtual Directory configuration script fails, check the run log or enable debug for the shell script to view specific errors. If the error message looks similar to this, rerun the script with a new keystore name:

  WLSTException: Error occured while performing cd : Attribute 
  oracle.as.ovd:type=component.listenersconfig.sslconfig,name=LDAP SSL 
  Endpoint,instance=%OVD_INSTANCE%,component=ovd1 not found
