Configuring the job scheduler

The job scheduler accepts job submissions and determines where to run them. As part of managing jobs, the job scheduler stores job information in an external job database. Configurations for the job scheduler includes the selection of the deployment target, data source JNDI name, database schema name, and endpoint job log location to be configured for the scheduler.

Before you begin

See the topic about creating a non-default job scheduler and grid endpoint database.

About this task

Stand-alone application servers or clusters can host the job scheduler. The first time a server or cluster is selected to host the grid scheduler, an embedded Apache Derby database is automatically created, and configured to serve as the scheduler database if the default data source JNDI name jdbc/lrsched is selected.

The job scheduler can be configured using the administrative console or by scripting. To configure the job scheduler using the scripting language, use the link to the job scheduler configuration administrative tasks provided in the related links at the bottom of this topic. To configure the job scheduler using the administrative console, see the following procedure.

Procedure

  1. Choose the environment to host the job scheduler. Use a stand-alone server for test environments. The stand-alone server can use the default Derby database. Use a cluster host for production environments. Although Derby is used as the default job scheduler database, you might want to use your own database. See the topic on creating a job scheduler and grid endpoint database for more information.
  2. Log on to the administrative console.
  3. Expand System Administration > Job Scheduler. The job scheduler panel opens.
  4. In the Scheduler hosted by list, select the deployment target.
  5. Type the database schema name. The default is LRSSCHEMA.
  6. Select the data source JNDI name from the list. If the default of jdbc/lrsched is selected, the default embedded Derby job scheduler database is created.
  7. Type the directory where the job scheduler and the batch execution environment write the job logs. The default is ${GRID_JOBLOG_ROOT}/joblogs.
  8. Click OK and save the configuration.
  9. If administrative security is enabled, enable application security and secure the job scheduler. See the topic on securing the job scheduler for more information. Only authorized users who are granted the lrmonitor, lrsubmitter, and lradmin roles, or a combination of the roles, through the administrative console are allowed access to the job management console.
