Problem summary
**************************************************************** * USERS AFFECTED: IMS Library Integrity Utilities for z/OS, * * Version 2 Release 1 (FMID=H27P210) users who * * use the MFS Reversal utility or the MFS * * Compare utility. * **************************************************************** * PROBLEM DESCRIPTION: When MFS Reversal utility or MFS * * Compare utility runs, ABEND0C4 can * * occur after reversing MFS source files * * or comparing MFS control blocks. * * * * The ABEND0C4 is caused by accessing * * freed internal work area in the * * storage. It occurs when one of the * * following conditions met: * * * * - When the internal work area in the * * storage obtained by MFS Reversal * * utility or MFS Compare utility is * * freed and other utility obtains the * * area immediately before MFS Reversal * * utility or MFS Compare utility * * re-accesses. * * * * - When MFS Reversal utility or MFS * * Compare utility runs on an * * environment that freed area in the * * storage is not accessible. One of * * the environment is CLIST * * environment. * * * **************************************************************** * RECOMMENDATION: Apply the maintenance for this APAR. * **************************************************************** MFS Reversal utility and MFS Compare utility accesses freed internal work area in the storage when closing data sets after reversing MFS source files or comparing MFS control blocks. If one of the following conditions met, the internal work area is not accessible and ABEND0C4 occurs. - When the internal work area in the storage obtained by MFS Reversal utility or MFS Compare utility is freed and other utility obtains the area immediately before MFS Reversal utility or MFS Compare utility re-accesses. - When MFS Reversal utility or MFS Compare utility runs on an environment that freed area in the storage is not accessible. One of the environment is CLIST environment. This APAR fixes MFS Reversal utility and MFS Compare utility not to access the internal work area in the storage after the area is freed.
