APAR status

• Closed as fixed if next.

Error description

• For AUTO_REORG enabled databases with a mixture of row-based
  tables along with either ITC or MDC or columnar tables,
  evaluation of the row-based tables for reclaim extents may be
  performed using ADMIN_GET_TAB_INFO() unnecessarily. Frequent
  execution of ADMIN_GET_TAB_INFO() may cause some lock contention
  with other applications, resulting in lock-wait or deadlock
  conditions for the applications.
  

Local fix

• Upgrade to fixpack inclusive of this APAR fix.
