CCIN or CTIN transactions have not been recognized.
CCIN and CTIN have not been installed on the server. The CCIN transaction installs a Client connection on the CICS server when using either the TCP/IP or SNA protocol. The CTIN transaction installs your client terminal definition on the CICS server.
If you are using TCP/IP or SNA, the CICS server must have CCIN installed. CTIN must also be installed if you require CICS 3270 emulation and are running in a supported configuration.
