Error description
A Liberty request is being processed. CICS has determined that a CICS task is not required for this work but allows for one to be created later if needed. During the processing of this request an attempt is made to directly access the CICS Task object. There isn't a CICS task associated with the thread so this call throws a RuntimeException. The user code does not catch this exception, so it eventually gets caught by the CICSTaskWrapper. The CICS code then tries to set an appropriate abend code in the TCA. The TCA does not exist because there is no CICS task. The attempt to set the abend code causes an 0C4 abend.
Local fix
Program should use the IsCICS method to check if the CICS API is available for use.
Problem summary
**************************************************************** * USERS AFFECTED: All CICS users * **************************************************************** * PROBLEM DESCRIPTION: 0C4 abend occurs when a Liberty * * request which does not require a CICS * * task tries to access the CICS Task * * object. * **************************************************************** A request that does not require a CICS task arrives in Liberty. An attempt is made to access the CICS Task object, without first using IsCICS.getApiStatus(). This fails and a RuntimeException is thrown. This exception is not handled by user code, but is eventually caught by the CICSTaskWrapper. CICS code then tries to report the error and indicate that an abend should occur. An attempt is made to set an abend code in the TCA. This fails with an 0C4 abend because there is no CICS task environment.
Problem conclusion
The CICS Liberty code has been changed to only set an abend code when there is a CICS task environment.
