Connect failed with error error
If you tried to connect to a CICS TS v4 system and the connection failed with the error NOTAVAILABLE CPSMAPI, it might be that you have not included the SEYUAUTH and SEYULOAD libraries in the STEPLIB & DFHRPL JCL respectively, or if you are connecting to a stand-alone (SMSS) CICS Region, there is an inconsistency in the version levels of the libraries. See Setting up the CICS management client interface for more information.
Otherwise, review the error information, check that the connection parameters are correct, and try to connect again. See Connecting to a system from the Preferences view for more information.
