Problem summary
**************************************************************** * USERS AFFECTED: All CICS users. * **************************************************************** * PROBLEM DESCRIPTION: A task running in a JVM server is * * unable to create a CICS task. * * NOT_AUTH_SET_USERID is shown in JVMERR. * **************************************************************** A Liberty JVM server is enabled with Liberty z/OS security active. Liberty handles a request that does not bind to a CICS task. Examples of such requests could be a HTTP request to retrieve a static resource or a servlet which does not interact with the JCICS API. This causes a thread local variable to be set to the current user ID, however this is not propagated into CICS or cleared once the request has been handled because no CICS task was bound to the thread. As a result when another request uses this thread with the same user ID no DFHSJJS SWITCH_PTHREAD_CONTEXT domain call is made because the existing logic does not believe a call is necessary. If this new request binds to a CICS task exceptions may occur as the task will not be running under the expected user ID. In reporting customer's case this caused a com.ibm.cics.domains.DomainException to be written to the JVMERR file with function: BUILD_TRANSACTION, response: EXCEPTION, reason: NOT_AUTH_SET_USERID
Problem conclusion
CICS has been updated to ensure the thread local variable used to store the user ID is cleared even if no CICS task is bound.
