Sort interface for the sort routine
The Sort interface is a front-end processor for the sort routine used in your installation.
Sort performs preliminary checking before passing control to your sort routine. The following is a list of supported sort routines:
- CA-SORT
- DFSORT
- PLSORT
- SYNCSORT
The Sort interface determines whether the data sets that are targeted for sorting, merging, or copying can use EXCP processing. If EXCP processing is appropriate, the Sort interface passes control to the sort program. If the interface detects that EXCP access is jeopardizing data integrity, it causes the sort program to use BSAM instead of EXCP as the access method.
The dynamic allocation of SORT WORK data sets by most sort products might be insufficient. Sort products base their allocations on the size of the data set. Because the data is compressed, the SORT WORK files are typically too small, resulting in the SORT CAPACITY EXCEEDED message. You can avoid this situation by specifying DD statements in the job step for your SORT WORK files.
SYNCSORT maintenance
The following maintenance items affect DATA ACCELERATOR Compression:
- SYNCSORT might receive the WER99A UNSUCCESSFUL SORT 363 W message. Use fix number 3303-1, which is included in Version 3.4, TPF4+ level.
- SYNCSORT Version 3.5 provides an early warning notice (EW4208-0) so the BSAM parameter can be honored for OUTFIL data sets.
