indicesThe system runs database maintenance jobs automatically on a daily and weekly basisbasis, and moves records every 15 minutes from the small temporary tables to the final tables. The maintenance jobs help to optimize large-scale deployments with by running bulk operations during off-hours and periodically reorganizing indices indexes on the database tables. The database maintenance runs as standard SQL Server jobs on SQL Server Standard and Enterprise Editions and is executed by the Verba Web Application service in the case of SQL Server Express Edition (where jobs are not supported). The SQL Server jobs are created during install time by the installer running specific SQL scripts. To run these scripts, the installer requires specific permissions on the SQL Server. For more information see SQL Server requirements.
The built-in maintenance jobs provide the following features:
| Actions | Description | Schedule |
|---|---|---|
| Bulk delete records | The action deletes records in a bulk operation where the retention expired or a matching deletion policy is configured. The data management policy which is executing the deletion only marks the records in the database for deletion and the bulk delete job deletes the records ultimately from the database tables. | Daily |
| Move data from temporary tables to the final tables | The action moves data from temporary tables which |
store data for |
15 minutes only to the final tables where the data resides for the long term. The move job runs on the following tables:
|
| Every 15 minutes | |
| Rebuild indexes | The action rebuilds |
indexes where the fragmentation is greater than 30% on all tables |
| Daily |
| Reorganize indexes | The action reorganizes |
indexes where the fragmentation is greater than 5% on all tables |
| Daily | ||
| Extend partitions | The action creates new partitions for the next 5 months and merges partitions with a small amount of data for the following tables:
| Daily |
