Configuring EDB Job Scheduler

The EDB Job Scheduler has a scheduler process that starts when the database cluster starts. To start the scheduler process, load the EDB Job Scheduler extension using the shared_preload_libraries parameter.

After you load the extension, create the extension using the CREATE EXTENSION command. The database in which you're creating the extension must be listed in the edb_job_scheduler.database_list parameter.

The CREATE EXTENSION command also creates two tables in the sys schema: jobs and job_run_details.

In addition, the EDB Job Scheduler provides two more GUCs:

• edb_job_scheduler.max_jobs_per_database — Controls the maximum number of jobs per database level.
• edb_job_scheduler.max_workers_per_database — Controls the maximum number of worker processes per database level.

To apply your changes, reload the configuration using pg_reload_conf() or pg_ctl reload.

Example

This example configures the EDB Job Scheduler extension.

1. Set the GUC parameter and the shared libraries parameter in postgresql.conf:

   Toggle WrapCopy

   edb_job_scheduler.database_list = 'edb'
   shared_preload_libraries='$libdir/edb_job_scheduler' 

2. Restart the database server.

3. Create the extension:

   Toggle WrapCopy

   # Using psql, connect to edb database as superuser
   psql -d edb -U enterprisedb
   # Create the extension
   CREATE EXTENSION edb_job_scheduler;
