Multiple SVCs for the same IDMS release

Products

• IDMS

Issue/Introduction

It is only necessary to have one SVC installed on an LPAR to service all of the IDMS systems regardless of the IDMS releases involved.

Some clients prefer to have a separate SVC per IDMS release.

Although it is rare, some clients run multiple environments (e.g. Test and Production) on the same LPAR, and for that reason it may even be desirable to implement multiple different IDMS SVCs at the same IDMS release.

This article documents the necessary CAIRIM input.

Environment

Release : All supported releases.
Component : IDMS/DB

Resolution

The following CAIRIM input will implement two SVCs, numbered 172 and 173, both for IDMS r19.0 (the "J0" represents r19.0).

//PARMLIB DD *
PRODUCT(CA IDMS) VERSION(GJJ0) INIT(GJJ0INIT) PARM(SVC=172)
PRODUCT(CA IDMS) VERSION(GJJ0) INIT(GJJ0INIT) PARM(SVC=173)

Note that in this case, CAIRIMU will have only one entry, but this is to be expected because it is showing product/release combinations, not SVCs.
