Linux: Capacity planning

Capacity planning for IBM Spectrum Protect™ includes managing resources such as the database, the recovery log and the shared resource area.

Before you begin

To maximize resources as part of capacity planning, you must estimate space requirements for the database and the recovery log. The shared resource area must have enough space available for each installation or upgrade.
  • Linux: Estimating space requirements for the database
    To estimate space requirements for the database, you can use the maximum number of files that can be in server storage at one time or you can use storage pool capacity.
  • Linux: Recovery log space requirements
    In IBM Spectrum Protect, the term recovery log comprises the active log, the archive log, the active log mirror, and the archive failover log. The amount of space that you require for the recovery log depends on various factors, including, for example, the amount of client activity with the server.
  • Linux: Monitoring space utilization for the database and recovery logs
    To determine the amount of used and available active log space, you issue the QUERY LOG command. To monitor space utilization in the database and recovery logs, you can also check the activity log for messages.
  • Linux: Deleting installation rollback files
    You can delete certain installation files that were saved during the installation process to free space in the shared resource directory. For example, files that might have been required for a rollback operation are types of files that you can delete.
