Memory usage
The Memory usage tab of Database Monitor provides information on memory usage in the database.
Note: This tab is available for InterBase databases only.
The diagram area provides visual representation of memory usage.
The pie diagram in the upper area represents the percentage of memory pool allocated for each of the following:
TRA (Transaction manager)
DYN
SQL (SQL statements)
REQ (User queries)
IRQ (Int. metadata queries)
TRG (Trigger requests)
PRM (Metadata structures)
SRT (Sort memory blocks)
CCH (Cache mgr/page buffers)
The chart in the lower area represents the memory pool usage history in progress:
the ordinate defines memory amount (in KB);
the abscissa defines time intervals.
