INTNUMInterval number: The nth sample database interval based on the start
time specified in the Create Performance Data (CRTPFRDTA) commandPD (5,0)
DTETIMInterval date (yymmdd) and time (hhmmss): The date and time of the
sample interval.C (12)
INTSECElapsed interval seconds: The number of seconds since the last sample
interval.PD (7,0)
PONBRPool number: Specifies the unique identifier of this pool. The value
is from 1 to 64.C (2)
POACTLPool activity level setting: The maximum number of processes that can
be active in the machine at the same time.PD (5,0)
POSIZPool size (in KB): The amount of main storage assigned to the pool.PD (9,0)
PORESPool reserved size (in KB): Specifies the amount of storage from the
pool that is dedicated to machine functions.PD (9,0)
PODBFPool 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)
PONDBFPool 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)
PODBPGPool 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)
PONDPGPool 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)
POAWNumber of active to wait transitions: Total number of transitions by
processes assigned to this pool from active state to wait state.PD (11,0)
POWINumber of wait to ineligible: Total number of transitions by processes
assigned to this pool from wait state to ineligible state.PD (11,0)
POAINumber of active to ineligible: Total number of transitions by processes
assigned to this pool from active state to ineligible state.PD (11,0)
PTTYPEType of tuning: The method used by the system to tune the storage pool: - 0 -- No tuning
- 1 -- Static tuning
- 2 -- Dynamic tuning of transfers into main storage
- 3 -- Dynamic tuning of transfers into main storage and to auxiliary storage.
C (1)
PTPAGEChange page handling. The method used by the system to determine when
to write changed pages to auxiliary storage: - 0 -- Use the system default
- 1 -- Periodically transfer changed pages to auxiliary storage.
C (1)
PTNDBFNon-database blocking factor. The amount of data (in KB) that should
be brought into main storage when a request is made to read non-database objects
from auxiliary storage.PD (3,0)
PTDBF1Database blocking factor (class 1.) The amount of data (in KB) that
should be brought into main storage when a request is made to read database
objects from auxiliary storage.PD (3,0)
PTDEX1Database exchange operation type (class 1.) The exchange operation
used to reduce the working set size. - 0 -- Use the system default
- 1 -- Allow exchange operations
- 2 -- Disable exchange operations
- 3 -- Disable exchange operations.
The data that already exists in main storage should be a good candidate
to be replaced when additional storage is needed in the storage pool.C (1)
PTDTS1Database type of transfer to auxiliary storage (class 1.) The method
the system uses to process a request to write an object to auxiliary storage. - 0 -- Use the system default
- 1 -- Purge object from main storage
- 2 -- Write object to auxiliary storage
- 3 -- Indicate object is a good candidate for replacement
- 4 -- Use the system page replacement algorithm.
