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.
