About the Scheduler Configuration
After you install BI Publisher using the BI Platform Installer and start the servers, the BI Publisher scheduler starts running and certain configurations occur.
-
The scheduler schema is installed to the database by the Repository Creation Utility as a preinstall step.
-
JMS is configured in your server for BI Publisher.
-
The WebLogic JNDI URL is configured.
-
Default threads per processor is set to 5.
See Installing and Configuring Oracle Business Intelligence for more information on configurations performed by the Oracle BI Platform Installer.
You can see this configuration in the Scheduler Configuration page: From the Administration page, under System Maintenance, click Scheduler Configuration. The figure below shows the Database Connection and JMS Configuration regions of the Scheduler Configuration page.
Configuring the Shared Directory
The Shared Directory is used to temporarily store data and files used by the scheduler while jobs are executing.
After a job completes, the temporary data for the job is deleted. If the BI Publisher scheduler is configured to run on different nodes or machines, you must define this directory. The directory is used to exchange data and document information among all the BI Publisher nodes and therefore must be accessible by all BI Publisher nodes. The size of the directory depends on the total size of the job data, output documents, and the number of concurrent jobs. The directory should be big enough to hold all the XML data and documents for all the parallel running jobs. If BI Publisher runs on different machines while this directory is not configured, the scheduler may fail.
If BI Publisher runs on a single machine, defining a shared directory is optional. BI Publisher uses the application server's temporary directory to store this data.
