Performance data files: QAPMPOOLB

This database file includes main storage pool file entries and lists the counters for system storage pools.

Field Name Description Attribute
INTNUM Interval number: The nth sample database interval based on the start time specified in the Create Performance Data (CRTPFRDTA) command. PD (5,0)
DTETIM Interval date (yymmdd) and time (hhmmss): The date and time of the sample interval. C (12)
INTSEC Elapsed interval seconds: The number of seconds since the last sample interval. PD (7,0)
DTECEN Century digit. C (1)
PONBR Pool number: Specifies the unique identifier of this pool. The value is from 1 to 64. C (3)
POACTL Pool activity level setting: The maximum number of processes that can be active in the machine at the same time. PD (5,0)
POSIZ Pool size (in KB): The amount of main storage assigned to the pool. PD (9,0)
PORES Pool reserved size (in KB): Specifies the amount of storage from the pool that is dedicated to machine functions. PD (9,0)
PODBF Pool database faults: Total number of interruptions to processes (not necessarily assigned to this pool) that were required to transfer data into the pool to permit the MI instruction to process the database function. PD (11,0)
PONDBF Pool nondatabase faults: Total number of interruptions to processes (not necessarily assigned to this pool) that were required to transfer data into the pool to permit the MI instruction to process nondatabase functions. PD (11,0)
PODBPG Pool database pages read: Total number of pages of database data transferred from auxiliary storage to the pool to permit the instruction to run as a consequence of set access state, implicit access group movement, and internal machine actions. PD (11,0)
PONDPG Pool nondatabase pages read: Total number of pages of database data transferred from auxiliary storage to the pool to permit the instruction to run as a consequence of set access state, implicit access group movement, and internal machine actions. PD (11,0)
POAW Number of active to wait transitions: Total number of transitions by processes assigned to this pool from active state to wait state. PD (11,0)
POWI Number of wait to ineligible: Total number of transitions by processes assigned to this pool from wait state to ineligible state. PD (11,0)
POAI Number of active to ineligible: Total number of transitions by processes assigned to this pool from active state to ineligible state. PD (11,0)
