| Offsets | Name | Length | Format | Description | |
|---|---|---|---|---|---|
| 0 | 0 | TIVPGIN | 4 | binary | Number of non-VIO (virtual input/output) page-ins for this step. This field includes page-ins required through page faults, specific page requests, and page fixes. It does not include page reclaims, page-ins for VIO data sets, and page-ins for the common area. |
| 4 | 4 | TIVPGOUT | 4 | binary | Number of non-VIO (virtual input/output) page-outs for this step. This field includes page-outs required through specific page requests including those pages “stolen” by the paging supervisor through infrequent use. It does not include page-outs for VIO data sets, and page-outs for the common area. |
| 8 | 8 | TIVRGNS | 4 | binary | Number of address space swap sequences. A swap sequence consists of a swap-out and swap-in of an address space. |
| 12 | C | TIVSIN | 4 | binary | Number of pages swapped in. This field includes: local system queue area (LSQA), fixed pages, and those pages that the real storage manager determined to be active when the address space was swapped out. It does not include page reclaims nor pages found in storage during the swap-in process (such as pages brought in from SRBs started after completion of swap-in Stage 1 processing). |
| 16 | 10 | TIVSOUT | 4 | binary | Number of pages swapped out. This field includes: local system queue area (LSQA), private area fixed pages, and private area non-fixed changed pages. |
| 20 | 14 | TIVVPI | 4 | binary | Number of virtual input/output (VIO) page-ins for this step. This field includes page-ins resulting from page faults or specific page requests on a VIO window. It does not include VIO swap-ins or page-ins for the common area. |
| 24 | 18 | TIVVPO | 4 | binary | Number of virtual input/output (VIO) page-outs for this step. This field includes page-outs resulting from specific page requests on a VIO window, and includes those pages “stolen” by the paging supervisor through infrequent use. It does not include VIO swap-outs or page-outs for the common area. |
| 28 | 1C | TIVSST | 4 | binary | Step service, in service units. This field is calculated as total job service minus the accumulated job service before this step's initialization. |
| 32 | 20 | TIVACT |
4 | binary | Step transaction active time, in 1024-microsecond units. Calculated as total job transaction active time minus the accumulated transaction active time before this step's initialization. |
| 36 | 24 | TIVPGNO | 2 | binary | Beginning with z/OS® V1R3, this field is always zero. |
| 38 | 26 | TIVTRANT | 4 | binary | Step transaction residency time, in 1024-microsecond units. That is the amount of time the transaction was in real storage. |
| 42 | 2A | TIVCPM | 4 | binary | Number of attempts to read data from an ESO hiperspace that were not satisfied because the data has been deleted. |
| 46 | 2E | TIVRCLAM | 4 | binary | Number of virtual input/output (VIO) reclaims for this step. |
| 50 | 32 | TIVCPGIN | 4 | binary | Number of common area page-ins for this step (link pack area (LPA) + CSA). |
| 54 | 36 | TIVHSPI | 4 | binary | Number of hiperspace page-ins from auxiliary to processor storage. |
| 58 | 3A | TIVPGSTL | 4 | binary | Number of pages “stolen” from the storage for this step. |
| 62 | 3E | TIVPGSEC | 8 | binary | Number of page seconds for this step, in page millisecond units. Calculated as: the number of pages used by this step times the processing time it held that number of pages. |
| 70 | 46 | TIVLPAI | 4 | binary | Number of link pack area (LPA) page-ins for the step. |
| 74 | 4A | TIVHSPO | 4 | binary | Number of hiperspace page-outs from processor to auxiliary storage. |
| 78 | 4E | TIVCPUS | 4 | binary | Step CPU service, in service units. |
| 82 | 52 | TIVIOCS | 4 | binary | Step I/O service, in service units. |
| 86 | 56 | TIVMSOS | 4 | binary | Step main storage service, in service units. |
| 90 | 5A | TIVSRBS | 4 | binary | Step SRB service, in service units. |
| 94 | 5E | TIVTSN | 8 | EBCDIC | Terminal symbolic name. |
