Problem IC91562
|
Status: Geschlossen |
UNDER RARE CONDITIONS, AUTOMATIC STATISTICS COLLECTION CAN LEAD TO AN ACTIVE LOG FULL CONDITION. |
| Produkt: |
DB2 FOR LUW / DB2FORLUW / 970 - DB2 |
| Problembeschreibung: |
When auto_runstats and auto_stmst_stats are both enabled, at any
given time, two automatic runstats might be running against
different tables. The runstats operation requires very few
locks. But, when it requests a lock, if LOCKLIST has been been
exhausted at that point in time, it will experience lock
escalation. Under the rare conditions where auto_stmt_stats is
performing an automatic runstats, and auto_runstats experiences
lock escalation while performing another automatic runstats, the
latter might have to wait for the former to complete. If the
auto_stmt_stats runstats is against a large table with multiple
indexes, it might take some time to complete, and the waiting
auto_runstats runstats might have to wait for a significant
amount of time. In this situation, active log full can be
reached. |
