Error description
When processing a VSAM data set that is opened using the ISAM Interface in VSAM, an Abend S16E RC24 will occur after installing PTFs for new function apars OA53954, OA53955, OA55315 which require greater control of the DEB control block. Users Affected: Any users of old applications that were written for ISAM data sets, DSORG=IS. User Impact: An ABEND16E rc24 will occur when closing the data set because the call to delete the DEB does not specify the new requirement of UNLOCKDELETE to ensure integrity. History: The ISAM Interface in VSAM was added many years ago to VSAM so that programs that accessed ISAM data sets using an ISAM DCB could access VSAM data sets without the code in the program being changed. Adding the parameter AMP=AMORG was the minimum JCL requirement to process a VSAM data set that was converted from an ISAM data set at some point in the past. DEBCHK/K
Local fix
If you do not run any ISAM programs, you are not affected by this issue. If you do run ISAM programs, you can ignore the ABEND16E's or apply the ++APAR which will be available by Sept 1,2018 or remove the New Function PTFs.
Problem summary
**************************************************************** * USERS AFFECTED: * * Users of ISAM Interface in VSAM. * **************************************************************** * PROBLEM DESCRIPTION: * * Abend 16E rc x'24' occurs during * * ISAM/VSAM Interface CLOSE. * **************************************************************** * RECOMMENDATION: * * Apply PTF. * **************************************************************** Problem occurs because Common O/C/EOV has recently changed to obtain a exclusive lock for the DEB before ISAM/VSAM CLOSE then an abend occurs when ISAM/VSAM CLOSE failed to obtain the lock for the DEB when it trying to delete the DEB with DEBCHK TYPE=DELETE.
Problem conclusion
ISAM/VSAM Interface was corrected to issue a DEBCHK TYPE=UNLOCKDELETE to delete the DEB and free the lock during CLOSE.
