| New DL/I release - DL/I VSE 1.12:
DL/I VSE 1.12 is the new DL/I release supplied with z/VSE V4.3 and provides virtual storage constant relief in the 24-bit area. The following additional functions are available:
Allocation of DL/I resources above 16 MB:
When running in a CICS/DLI online environment, the following DL/I resources can be allocated above the 16 MB line of storage:
- PSBs and their transaction working copies
- HD data buffers
- Most of the DL/I action modules
- DL/I user exit routines (excluding randomizers)
Moving HD buffers above the 16 MB line will also allow for keeping more data in storage with possibly faster access to the DL/I data.
DL/I GETVIS storage in separate subpools:
GETVIS storage allocated for different types of DL/I resources is assigned to different sub-pools. This includes:
- PSBs loaded during CICS/DLI initialization
- PSB working copies for the single transactions
- Buffer pool for HD databases
- Action modules and user exit routines
- Queuing elements of the Program Isolation function
The amount of storage that is held by the different subpools can be viewed with their respective subpool-IDs.
DL/I VSE 1.12 is the only DL/I release that can be used with z/VSE V4.3. It replaces DL/I VSE 1.11 and DL/I DOS/VS 1.10.
