APSB call
The Allocate PSB (APSB) calls are used to allocate a PSB for an ODBA application.
Format
| Call Name | DB/DC | IMS DB | DCCTL | DB Batch | TM Batch |
|---|---|---|---|---|---|
| APSB | X | X |
Parameters
- aib
- Specifies the application interface block (AIB) that is used for
the call. This parameter is an input and output parameter.
These fields must be initialized in the AIB:
- AIBID
- Eye catcher. This 8-byte field must contain DFSAIBbb.
- AIBLEN
- AIB lengths. This field must contain the actual length of the AIB that the application program obtained.
- AIBRSNM1
- Resource name. This 8-byte, left-justified field must contain the PSB name.
- AIBRSNM2
- This is the 4-character ID of ODBA startup table representing the target IMS of the APSB.
Usage
The ODBA application must load or be link edited with the ODBA application interface AERTDLI.
The APSB call must be issued prior to any DLI calls.
The APSB call uses the AIB to allocate a PSB for ODBA application programs.
z/OS® Resource Recovery Services (RRS)
must be active at the time of the APSB call. If RRS is
not active, the APSB call will fail and the application will receive:
AIBRETRN = X'00000108'
AIBREASN = X'00000548'
