CICS server PTF requirements

See the README file for the latest details on APARs and PTFs applicable to the CICS® Universal Client.

Terminal sign-on capability

CICS servers require APAR fixes to support the terminal sign-on capability available in this release of CICS Universal Client; see Supported software for details of the APAR relating to your CICS server. If the server does not have the required APAR applied and the '-a' option is not specified when the cicsterm command is issued, the installed terminal will give unpredictable results.

Timeout support

Any TXSeries® or CICS Transaction Server on the Windows® and UNIX® operating systems must include the appropriate PTF level to provide complete support for timeouts. See Supported software for details.

If the server does not have the required APAR applied and the '-a' option is not specified when the cicsterm command is issued, the CTIN transaction abends with code A42B. You see the following:
  • The CICS Universal Client displays the message:
    CCL7053E Errors found while communicating with server
  • This message is written to cicscli.log:
    CCL3105 Inbound CICS data stream error (CTIN,4, 0)
  • On the server, this message is written to CSMT.out:
    ERZ042004E/0112: An invalid request was received from client
  • console.msg includes this message:
    ERZ014016E/0036: Transaction CTIN Abend A42B
