Local fix
Problem summary
**************************************************************** * USERS AFFECTED: All DB2 V10 and V11 users for z/OS CPU- * * SYSPLEX PARALLEL QUERY. * **************************************************************** * PROBLEM DESCRIPTION: ABEND04E RC00C90101 DSNISEGD ERQUAL5124 * **************************************************************** * RECOMMENDATION: * **************************************************************** DB2 has an internal flag to identify if there is at least one parallel child workfile that exists. During the commit phase, DB2 will reset it to zero without any checking. For a CPU- SYSPLEX Parallel query, if the parent creates its own local workfiles, deletes them and then does a commit, there's a rare timing window that will result in CTCurWFb (current workfile storage) becoming negative, since when this internal flag is reset, it may have a child task running and DB2 will reset it mistakenly.
Problem conclusion
DB2 is changed to initialize the internal flag only if there are no child task running, so that the CTCurWFb value going negative and subsequent abend are avoided.
Temporary fix
