Oracle - Enterprise Manager extractor

Ensure that you create a database user and assign the appropriate rights. During ETL configuration, specify these user details so that the ETL can connect to the database for extracting data.

You must configure the ETL to connect to OEM for collecting the OEM metrics. ETL configuration includes specifying the basic and optional advanced properties. While configuring the basic properties is sufficient, you can optionally configure the advanced properties for additional customization.

A. Configuring the basic properties

Some of the basic properties display default values. You can modify these values when required.

To configure the basic properties:

1. Navigate to Administration > ETL & System Tasks, and select ETL tasks.

2. On the ETL tasks page, click Add > Add ETL. The Add ETL page displays the configuration properties. You must configure properties in the following tabs: Run configuration, Entity catalog, Oracle OEM Configuration, and Connection parameters
   
   

3. On the Run Configuration tab, do the following:

   1. Select Oracle Enterprise Manager Extractor from the ETL module list. The name of the ETL is displayed in the ETL task name box. You can edit this field to customize the name.

   2. Specify whether you want to import the performance and configuration metrics for all entities or import only performance metrics for database instances and RAC clusters.
4. Click the Entity catalog tab, and select one of the following options:
   

   • Shared Entity Catalog: Select if other ETLs access the same entities that are used by the OEM ETL. This is the default selection.

     • From the Sharing with Entity Catalog list, select the entity catalog name that is shared between ETLs.

   • Private Entity Catalog: Select if only this ETL is used for extracting data from the OEM resources.

5. Click the Oracle OEM Configuration tab, and configure the following properties:

   Property	Description
   Import database data	Specify whether you want to import the database data.
   Import server data	Specify whether you want to import data from the monitored hosts. The ETL imports data from the following types of hosts: Database server Instances without an Oracle database running on them
   Import ASM data	Specify whether you want to import data from the ASM entities, such as clusters and instances. The default configuration is to import this data.
   Import PDB data	Specify whether you want to import data from the pluggable databases. The default configuration is to not import this data.
