APAR status Closed as fixed if next. Error description The server region BBOTRX1S was cancelled after BBOTRX1A returned a reply message and before BBOTRX1A received a prepare request. When the control region BBOTRX1A received prepare request, he found that the server region had gone, so raised CORBA::INTERNAL exception. After that, he never returned a reply message to BBOTRX2A. So the syncpoint processing hang up.Local fix Problem summary **************************************************************** * USERS AFFECTED: All users of WebSphere Application Server * * V4.0 for z/OS and OS/390. * **************************************************************** * PROBLEM DESCRIPTION: An attempt to mark a transaction for * * rollback only after asynchronous RRS * * backout during transaction pre-prepare * * can cause assertion failure in the * * control region. The assertion will be * * surfaced in the job log of the control * * region as a BBOU0022E Assertion failed * * message. * **************************************************************** * RECOMMENDATION: * **************************************************************** If a server region in a subordinate node of a transaction abends during the execution of before_completion, RRS will drive an asynchronous application backout. As part of the abend processing, the ORB will throw a system exception to the caller. OTS handles system exceptions by marking the current transaction for rollback only. Since the current transaction was already marked for rollback only by RRS, RRS indicates that there was a UR state error. When the OTS transaction is in a state of pre-prepare, this UR state error was unexpected and caused an assertion failure.Problem conclusion Temporary fix Comments This APAR is being closed FIN with concurrence from the submitting customer. A solution to this problem will be delivered in a WebSphere Application Server for z/OS and OS/390 release within the next 18 month. . A fix for the problem reported by this APAR has been provided in PTF UQ58682 of WebSphere Application Server V4.0.1 for z/OS and OS/390.
