E Collecting OCM Data Using Oracle Harvester

Oracle Harvester

Oracle Harvester only harvests data for targets that are managed by Enterprise Manager. Because Oracle Harvester has the same OCM dependencies, Oracle Harvester enables the gathering of target configuration data by leveraging Enterprise Manager collection methods thus precluding the need to install OCM on target homes managed by Oracle Harvester.

Highlights of Oracle Harvester

The following are highlights of Oracle Harvester:

• Data is uploaded by default against the same credentials with which OCM in the Oracle Management Service (OMS) home is configured.

• Requires OCM to be configured and running in the OMS home for Enterprise Manager.

• Gathers target configuration data from the Management Repository

• Automatically runs periodically so no user intervention is required

Oracle Harvester and OCM

When you install Enterprise Manager, Oracle Harvester and Oracle Configuration Manager are automatically installed as are all the necessary subcomponents. The Oracle Harvester will run as long as the OCM in the OMS home is configured and running.

OCM must be enabled in the Oracle Home of the OMS and configured (and running in connected mode) in the Instance Home of the OMS. The reason is that the Oracle OMS target will not be discovered by the OCM collector if ORACLE_CONFIG_HOME is not set.

Perform the following steps to ensure the Oracle OMS target is discovered:

1. Locate the OMS instance home.

   In the $ORACLE_HOME/sysman/config/emInstanceMapping.properties file (where ORACLE_HOME is the Oracle Home of the OMS), there is an entry referencing a file called emgc.properties.

   The directory in which the emgc.properties file is located is the "instance home" of the OMS. In the following example, /u01/app/oracle/product/gc_inst/em/EMGC_OMS1 is the instance home of the OMS:

   EMGC_OMS1=/u01/app/oracle/product/gc_inst/em/EMGC_OMS1/emgc.properties

2. Set the environment variable ORACLE_CONFIG_HOME to the directory of this emgc.properties file.

   Example:$export ORACLE_CONFIG_HOME=/u01/app/oracle/product/gc_inst/em/EMGC_OMS1

3. Configure OCM.

New For Enterprise Manager Release 12.1

By default, all targets are uploaded using the credentials used to register Oracle Configuration Manager in the OMS Home. In Enterprise Manager release 12.1, you have the option of assigning a Customer Support Identifier (CSI) to each target home.

The Oracle Harvester supports uploading configuration data to different CSIs for each different Oracle Home.

The steps include:

1. Ensuring that the Oracle Harvester has run. This job runs automatically. The status of the run can be monitored from the Support Identifier Assignment page. To access this page from the Enterprise Manager home page, select Setup, then select My Oracle Support. From the menu, select Support Identifier Assignment.

2. Setting My Oracle Support preferred credentials. From the Enterprise Manager home page, select Setup, then select My Oracle Support. From the menu, select Set credentials and supply any valid My Oracle Support credentials.

3. Assigning the Support Identifier.

   1. From the Enterprise Manager home page, select Setup, then select My Oracle Support. Select Support Identifier Assignment and provide the correct user name and password. Select Set credentials.

   2. Select Home. Click Assign button. Select CSI and click OK.

4. Ensuring the message displays indicating the assignment was successful. The message reads:

   Support Identifier has been assigned for 1 Oracle homes. The changes in the Customer Support Identifiers will be reflected in My Oracle Support after the next Harvester run.
   

Viewing CSIs in Enterprise Manager

You can see the CSI associated with a target by viewing the target property or by doing a configuration search with CSI set as the search criteria. Any user with operator privilege on all targets for a given Oracle Home can assign a CSI for that Oracle Home.

Refer to the help in the Enterprise Manager interface on how to access this information.

Oracle Configuration Manager

Oracle Configuration Manager is installed and configured automatically when you install an Oracle product. It is installed in the product Home and collects configuration data for all targets installed in that Home.

The OCM setup requires specifying the My Oracle Support account and password, or My Oracle Support account and Customer Support Identifier (CSI). Configuration data will be uploaded using this information and can be viewed by logging in to My Oracle Support using the same credentials.

OCM must be installed in every Oracle Home from which you want to upload configuration data to Oracle. In addition to being part of the product installation, OCM can also be downloaded from My Oracle Support. The Mass Deployment tool is available to help with deploying OCM across data centers. The OCM kit is available from the Collector tab on My Oracle Support.

Once OCM is installed, no additional work is required. By default, automatic updates are enabled and you are encouraged to use this feature to ensure you are always running the latest version of OCM. This feature can be disabled if required, for example, for security reasons. If you disable the feature, you can turn it on by executing the following command:

<ocm_install_root>/ccr/bin/emCCR automatic_update on

To find more information about OCM, perform the following steps:

1. Log into My Oracle Support at https://support.oracle.com

2. Access the Collector tab. The What, Why, How, Using It, and Additional Resources sections all contain useful information.

Troubleshooting Configuration Data Collection Tools

The following sections describe how to resolve issues with the configuration data collections.

In Enterprise Manager release 12.1.0.2, ensure that collection data is uploaded to Oracle by using the emccr status command. Look at the last uploaded date and time.

Note: This emccr status command shows that collected data was uploaded, but does not ensure the Oracle Harvester collections were successful and uploaded.
