The QAPMPOOLL file is provided to allow for compatibility between Collection Services and the performance monitor. The QAPMPOOL file is created when the performance monitor database files are migrated with the Convert Performance Data (CVTPFRDTA) command to a newer release. Collection Services does not create the QAPMPOOL file. Rather, Collection Services creates the QAPMPOOLL file.
This data includes main storage pool file entries and lists the fields in the storage pool file.

| 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) |

| PTPAGE | Change page handling. The method used by the system to determine when
to write changed pages to auxiliary storage:

C (1) |
| PTNDBF | Non-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) |
| PTDBF1 | Database 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) |
| PTDEX1 | Database exchange operation type (class 1.) The exchange operation
used to reduce the working set size.
|
C (1) |
| PTDTS1 | Database type of transfer to auxiliary storage (class 1.) The method
the system uses to process a request to write an object to auxiliary storage.
