Can IDMSINTC connect IDMS to CICS across LPARs?

Issue/Introduction

This article discusses the ability for the IDMSINTC/IDMSINTL interfaces to connect IDMS to a CICS region on a different LPAR.

Can the IDMSINTC and IDMSINTL interfaces be used to connect IDMS and CICS address spaces on different LPARs?

Environment

Release: All supported releases.

Resolution

No.

The IDMSINTC and IDMSINTL interfaces use an SVC to connect CICS to IDMS and so the two address spaces must be on the same LPAR. The recommendation is to set up a "routing" IDMS CV in the same LPAR as CICS and use DDS (with NODEs using communication method VTAM, TCP/IP or CCI) to send transactions to the desired CV.

For some samples of how to set up a DDS connection using TCP/IP, see IDMS Sample DDS TCP/IP definitions .
