Performance data files: QAPMPOOLT

Performance data files: QAPMPOOLTINTNUMInterval number: The nth sample database interval based on the start time specified in the Create Performance Data (CRTPFRDTA) command.PD (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)DTECENCentury digit.C (1)PONBRPool number: Specifies the unique identifier of this pool. The value is from 1 to 64.C (3)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.
