End-of-service documentation

When a CICS® product is withdrawn from support, the information remains available for use by clients with extended support contracts, but is no longer maintained. This section provides links to the documentation for back-level versions of CICS Transaction Server: Version 5.1, Version 4.2, Version 4.1, Version 3.2, and Version 3.1. Such product information is provided as-is, in support of your extended service contract and solely for the applicable product and version.

Documentation is available online in IBM Knowledge Center. PDF and legacy information center formats are available for download without charge from IBM Publications Center. (Note that information centers were superseded in 2014 by IBM Knowledge Center.) Some documentation is translated into languages other than English.
