Dealing with CKR1400 MESSAGE - Running on an unsupported version z/OS x.y.z

Technote (troubleshooting)


While zSecure Admin or zSecure Audit can be running at a level lower than an operating system at a higher level, zSecure is unable make use of the new features in the newer version of z/OS and possibly new RACF segments so a warning message is displayed.


Message CKR1400 04 Running on an unsupported version xx.yy.zz of z/OS, results are unpredictable - please upgrade

or similar mismatch of releases with zSecure lower than z/OS


The zSecure suite of products provides advanced use of the features available on the operating system it is written for, and those previous versions of the OS. It cannot make full use of services, features and upgrades (such as new classes and segments within RACF) of a release of z/OS later than its level. At this point, to avoid confusion as to why newer facilities aren't in use, the diagnostic message is written. To ensure it is not overlooked in the message stream, it assigns a return code of 4 (RC=04).

Diagnosing the problem

Locate the message in the SYSPRINT message stream

Resolving the problem

You can use the SUPPRESS MSG=1400 command (either in PREFACE or in the default set of commands issued for all jobs) to suppress the CKR1400 message and its resulting return code setting of 4. This will cause the job to issue a return code 0 unless other errors occur.

As of zSecure Release 1.12, it is also possible to specify NOWARNING on the OPTION statement as shown in the User Guide:


    Reset the return code to 0 when warning messages have been issued. If the
    internal return code is set to 4 or less as a result of warning messages, the
    return code is reset to 0 at the end of the CARLa run. This option is only valid
    on the OPTION command.
