This article documents any issues that need to be taken into consideration for IDMS when upgrading to IBM’s Enterprise COBOL Release 6.x.


Release: All supported releases
Component: CA-IDMS/DC


There are no APARs required that are specific to COBOL 6.x. However there are some for COBOL 5.x. See What PTFs are required for CA IDMS to be compatible with IBM's Enterprise COBOL release 5.1 and above? .

Specific to COBOL 6.x or higher, client experiences show that when running online dc-cobol programs in the CV, it will make more use of the XA REENTRANT POOL (additional runtime modules loaded). The recommendation is to increase the XA REENTRANT POOL by 20% when moving to COBOL 6.x or later and then monitor usage to see if any more increase may be needed.
