Disk space

The system databases reuse disk space when messages are removed.

These databases use disk space up to the maximum size of the file system. As a message is removed from a database, that file's disk space remains open to store another message. As more messages are added to the database, the disk utilization increases.

To restore database disk space and make it available for other messages:

  1. Clean all records in the recovery and error databases.
  2. Initialize the databases and control files.

Cleaning databases

The recovery and error databases sometimes require cleaning at the site level. When cleaning the databases, check to ensure the messages are not required.
