In Store version 1.0, if the Store database file volume has already reached its limit, shortening the data retention period does not reduce the file size. In this case, after specifying a short retention period, back up the Store database, and then restore it.

For details about how to specify a data retention period, see the chapter explaining management of operation monitoring data in the Job Management Partner 1/Performance Management User's Guide. For details about how to back up and restore the Store database, see the chapter explaining backup and restore in the Job Management Partner 1/Performance Management User's Guide.

Unexpected service stoppage or machine shutdown may have produced illegal data in the Store database. Take one of the following steps:

• If the Store database has been backed up, restore it.
• If the Store database has not been backed up, stop the Agent Store service and delete the corresponding database file (*.DB files and *.IDX files), and then restart the service.
