Why does the message "9031 Unable to initialize link C10LINK2. Reason=AppcReturnCode::UnrecognizedModeName" appear in the WebLogic log or the CRM standard error file?

The most probable cause is that the mode name specified in the console is not recognized by the back-end system. To correct this: 1. Verify that the mode name is a valid VTAM mode name for your system. 2. For IMS or batch, verify that the mode name is defined on the region logical unit. 3. For CICS, verify that the mode name is defined in the CICS RDO session definition.
