IN PURESCALE ENVIRNMENT, 3-WAY DEADLATCH COULD HAPPEN IN RARE TIMING SCENARIO. | |

Problembeschreibung: | |
In rare timing scenario, 3-way deadlatch among SQLO_LT_SQLB_BPD__bpdLatch_SX and SQLO_LT_SQLD_PAGE_CACHE__pageCacheLatch and SQLO_LT_SQLD_TCB__loadInProgress could happen. This can only happen on pureScale environment. This can be hit when the following 2 situation happens at the same time; 1) Multiple sessions are accessing the same table. 2) The TCB of the index of the table being accessed is being reloaded because its definition is changed on the remote node. SQLO_LT_SQLB_BPD__bpdLatch_SX is an untrackable latch so we cannot determine this 3-way deadlatch using stacks or db2pd -latches output. | |
