Error description
Online reorganization of logically-related databases gets ABENDS0C4 when the number of temporary unload files exceeds 131. The workaround is to increase the value of the UNLSPAC base configuration parameter, which increases the size of each temporary unload file.
Local fix
The workaround is to increase the value of UNLSPAC base configuration parameter, which increases the size of each temporary unload file. Try UNLSPAC=800 initially.
Problem summary
**************************************************************** * USERS AFFECTED: All users of IBM IMS Online Reorganization * * Facility V1.1. * **************************************************************** * PROBLEM DESCRIPTION: Online reorganization of * * logically-related databases gets * * ABENDS0C4 when the number of temporary * * unload files exceeds 131. * * The workaround is to increase the value * * of UNLSPAC base configuration * * parameter,which increases the size of * * each temporary unload file. * **************************************************************** * RECOMMENDATION: Apply the maintenance for this APAR. * **************************************************************** When the database has external logical relationship, data space is used to pass data to SAS. ORF creates multiple data spaces. When the number of temporary unload files exceeds 131, the pointer that points to next data space is broken. This causes the ABENDS0C4. New keywords, UNLSPAC and UNLUNIT have been added to allow specifying allocation value for temporary unload data set per job. In addition, the following problem has been fixed in this APAR: - If the database has external logical relationship and "Dataset in use" is occurred for a shadow DBDS in Post Reorg phase or Image copy phase, ORF retries allocating the shadow DBDS to prevent the ORF job from immediately terminating with an error. ======================== = DOCUMENTATION CHANGE = ======================== IBM IMS Database Solution Pack for z/OS Version 2 Release 2 IMS Online Reorganization Facility User's Guide (SC27-9039) Refer to topic What's new in IMS Online Reorganization Facility (https://www.ibm.com/docs/en/ims-dbsolutionpack/2.2?topic=overvi ew-whats-new-in-ims-online-reorganization-facility) in IBM Documentation for doc changes associated with this APAR.
Problem conclusion
Code has been changed so that ORF processes correctly if the database has external logical relationship and the number of temporary unload files exceeds 131.
