OTMA coexistence considerations

When an IMS 15 OTMA coexists with earlier versions, certain considerations apply.

IMS Version 12 and IMS Version 13 instances of IMS Connect can connect to OTMA tpipes that support parallel processing of RESUME TPIPE requests after the appropriate coexistence APARs are applied. The APARs are required only for IMS Version 12 and IMS Version 13 instances of IMS Connect that connect to tpipes in which tpipe parallelism is enabled.

For connections from IMS Version 12 and IMS Version 13 instances of IMS Connect, support for the parallel processing of RESUME TPIPE requests can be enabled only from the OTMA client descriptors.

Previous versions of IMS Connect require these compatibility fixes:
  • IMS Connect Version 13 APAR/PTF PM93878/UK98632
  • IMS Connect Version 12 APAR/PTF PM93880/UK98633
