First is the Red Alert for PM51093 that was recently posted on the Red Alert website: http
Other potential data loss HIPERs include:
Correction: APAR remains open. Corrective relief, AM55070, is available from DB2 Technical Support. The estimated PTF availability date is April 6.
Notes: This is a problem specific to freespace reuse and later rollback. There should be no latent data corruption. i.e. the only way a customer would have data corruption is if they actually encountered an abend during rollback, in which case the page would be marked broken and they should report the problem to IBM Support.
There is no need for customers to proactively check for problems. If such is desired, then any utility such as DSN1COPY, REORG, COPY or any application access would report a page marked broken.
Correction: PTF UK76352 is available (not yet RSU)
Notes: There is no actual data loss, however, the potential exists for corrupted data pages and orphan pointer records. Customers wishing to proactively check for this condition can use DSN1COPY with the CHECK option, which runs offline and is non-disruptive.
However, the IBM COPY utility would automatically detect corrupted data pages, so a normal backup cycle should be sufficient to validate data. If DB2 detects a problem, then the page may be marked broken. This can be reset by REPAIR using REPAIR LOCATE db.ts PAGE(nnnn) RESET. The IBM REORG utility will correct the page corruption.
