Managing the UC Monitor Database › Hard Drive Maintenance

Hard Drive Maintenance

UC Monitor contains several tables that it consistently accesses for read/write (I/O) operations. These tables occupy most of the disk space on the drive where the management console is installed. The I/O operations cause disk fragmentation over time.

We recommend that you perform the following tasks to maintain the hard disk drive (HDD).

Regular defragmentation

For databases larger than 10 GB in size, defragment the <install path> drive every month. Before starting the defragmentation process:

• Maintain at least 20 percent of the drive as free disk space.
• Stop all CA UCM services, including the CA UCM MySql51 service. You can restart these services after defragmentation is complete.

Regular backups

CA Performance Center data sources constantly write to the HDD. During data-seek operations in support of report compilation, the drive heads move about, simultaneously writing and reading. As with any HDD, this stress over time can lead to failure. To recover quickly with minimal data loss, schedule a regular database backup.
