Setup for Presentation Catalog Replication

To enable Presentation Catalog replication, set up the conditions described in this section.

Edit the instanceconfig.xml for Replication

For each instance Oracle BI Presentation Services, you need to edit the Oracle BI Presentation Services configuration file (instanceconfig.xml) to:

• Enable replication. By default, the replication functionality is disabled for instances of Oracle BI Presentation Services.
• Configure replication for a clustered environment. In a clustered environment, several instances of Oracle BI Presentation Services can share the same Presentation Catalog. For replication to work properly, you need to:
  • Ensure that each instance of Oracle BI Presentation Services writes to its own log file to avoid concurrency issues
  • Make sure that changes made by all instances are taken into account during import and export operations
• Specify the number of records to be kept in a replication log file
• Specify the time period (in hours) from which replication log files are to be read for replication operations.

For more information on editing the instanceconfig.xml file for replication, see Editing the instanceconfig.xml File for Replication.

Create the Oracle BI Presentation Services Replication Agent Configuration File

You need to create the Oracle BI Presentation Services Replication Agent's configuration file (config.xml) to specify which folders on which instances of Oracle BI Presentation Services are to be replicated. For more information, read Creating the config.xml File for Replication.

Use Oracle BI Presentation Services Replication Agent

You can run the Oracle BI Presentation Services Replication Agent (sawrepaj) on any computer that has network access to both instances of Oracle BI Presentation Services. This agent handles all the replication tasks. It has some command line options. For more information, see Using the Oracle BI Presentation Services Replication Agent.

Copy Presentation Catalog Files

The Oracle BI Presentation Services Replication Agent copies changes made to a Presentation Catalog. Because it only copies changes, and not the entire contents, you must first make a copy of the source Presentation Catalog on each of the subscribing instances of Oracle BI Presentation Services.

Maintain the List of Presentation Catalog Folders to Be Replicated

Because the Presentation Catalog came from another instance, the list of catalog folders to be replicated may be incorrect. Use the sawrepaj mark command to maintain the list of catalog folders to be replicated. For more information, see Using the Oracle BI Presentation Services Replication Agent.
