Migrating TMRA connections from Local Option to TCP/IP

IMS 14 is the last version to support the Local Option for connections between IMS Connect and IMS TM Resource Adapter. In IMS Version 13, Local Option is supported for 31-bit only. Migrating TMRA connections from Local Option to TCP/IP requires changes to the IMS Connect TCP/IP configuration member.

Local Option uses the z/OS Program Call function for communications between IMS Connect and IMS TM Resource Adapter that runs on WebSphere® Application Server for z/OS®

When you migrate from Local Option to TCP/IP connections, consider changing the following configurations:
  • In the IMS Connect HWSCFGxx configuration member, change the LOCAL value that the PORT and PORTID parameters specify to a unique TCP/IP port number. Valid values for the TCP/IP port numbers are decimal numbers from 1 to 65535. For example, change from PORT=(ID=LOCAL) or PORTID=(LOCAL) to PORT=(ID=nnnn) or PORTID=(nnnn).
  • In the IMS TM Resource Adapter connection factory Custom Properties pages, complete the following actions:
    • Disable Local Option connections by clearing the IMSConnectName field.
    • Enable TCP/IP connections by specifying the HostName and PortName fields.
