I upgraded my CICS to version 7.0 (this is CICS Transaction Server 5.3).
CICS PLT startup fails with abend AEI0.
Support for IBM's CICS Transaction Server (5.3) requires new VPE modules named VPEHJE70 and VPEHJN70 to execute in CICS 7.0.
VPE-based products that execute in CTS 5.3 need the new modules.
CA Ideal, CA Datacom , CA Datadictionary's DDOL and CA Dataquery require VPE support for CTS 5.3.
