Use the System Health portlet to track current system-level space usage. This portlet displays segmented bar graphs that show normal, degraded and critical space usage ranges.

Parameter Description Actions
Total disk space Percentage of total disk space in use across the system If system disk space usage moves beyond the normal range (80%), add disk capacity.
DBC disk space Percent of disk space assigned to DBC currently in use The DBC database contains logs, system tables and views, and other functions necessary for system operation.

If DBC space usage moves beyond the normal range, reallocate perm space from DBADMIN to DBC.
