TOTAL DIST STORAGE BELOW 2 GB (MB)
Total DIST storage below the bar. This includes:
  • Fixed length storage use
  • Getmained storage
  • Save areas
  • Variables

Field Name: SW0225DI

TOTAL GETMAINED STORAGE (MB)

Start of changeTotal storage acquired by GETMAIN. This includes space for virtual pools, EDM pool, compression dictionary, castout buffers, and the data space lookaside buffer, and data space buffer pool control blocks.End of change

This figure can be different from the sum of GETMAIN storage items shown in the statistics DBM1 storage, because DB2 does not produce grouping statistics for all GETMAIN storage.

Field Name: QW0225GM

TOTAL VARIABLE STORAGE (MB)
Total storage used by all variable pools. This includes storage used by:
  • System agents
  • Local agents
  • RID pool
  • Pipe manager subpool
  • Local dynamic statement cache control blocks
  • Local dynamic statement cache statement pool
  • Buffer and data manager trace tables
  • A list of objects in restricted state including the new PRO state. If consumption of this storage pool is high, review restrictive exception state of database objects and check whether they can be resolved or reduced.

Field Name: QW0225VR

NUMBER OF ACTIVE CONNECTIONS

The number of active connections, or active and disconnected DBAT threads.

Field Name: SACDBATS

NUMBER OF INACTIVE CONNECTIONS

Field Name: QDSTCIN2

TOTAL FIXED STORAGE (MB)

Total amount of fixed storage.

Field Name: QW0225FX

TOTAL GETMAINED STACK STORAGE (MB)
