Problem summary
**************************************************************** * USERS AFFECTED: All the users who use IMS Database * * Recovery Solution Pack V1R1 might * * be affected. * **************************************************************** * PROBLEM DESCRIPTION: Intermittent S0C4 abend * * with BPE parser. * * There are tow other problems * * are fixed in this APAR: * * 1. 0C4 in index list area. * * 2. IB error when empty data * * was passed over from DRF. * **************************************************************** * RECOMMENDATION: INSTALL CORRECTIVE SERVICE FOR APAR/PTF * **************************************************************** In the parsing processing, a storage was freed after the statement was processed, and then a new storage was obtained for the next statement. We use two identical storages, one for input and one for the output data. However, sometimes, we freed the wrong data storage, and BPE could not find the input storage and so an intermittent S0C4 occurred. For the 0C4 in the index list area, the problem occurred when we have BLD_SECONDARY (select). If a primary index needs to be added, we need to have a larger storage to hold the data. And because every member in the recovery list shares same index list, we need to update every DBD with the pointer of the new storage, but somehow it was updated only for the DBD that has the primary index. For the IB error, the problem occurred when an invalid index was selected in BLD_SECONDARY. If the wrong index was the only one in the selected index list then we passed an empty statement to IB and so got rejected.
Problem conclusion
The parsing module was modified to make sure that we re-use two storages that contain input/output data to BPE for processing. The storges are cleared after one statement is processed and get ready for the next. FRXVSTA2 and FRXTAU00 have been modified for index list issues.
