Allocate these resources above the 16 MB line of storage when running in a CICS/DLI online environment: PSBs, HD data buffers, most DL/I action modules, the MPS mirror program DLZBPC00 and more.
GETVIS storage allocation for different types of DL/I resources is assigned to different subpools including: DLIPSB, DLIWPS, DLIBFR, DLIMOD and DLIQWA.
With more than one Multiple Partition Support System (MPS), the DL/I Master Partition Controller for the DL/I MPS function can be activated in more than one CICS/DLI online partition at the same time.
DL/I Hierarchical Direct (HD) databases can be allocated on more than one VSAM dataset to get over the 4 GB limit. Up to five datasets can be defined, increasing the maximum database size to 20 GB.
IBM DL/I VSE supports the storage protection introduced with CICS Transaction Server for VSE/ESA Release 1. This increases the availability and integrity of the overall CICS/DLI online system.
