Explicit and implicit rebind may result in deadlock on rebind sequence lock | |
Produkt: | |
DB2 FOR LUW / DB2FORLUW / A10 - DB2 | |
Problembeschreibung: | |
Upon implicit or explicit rebind, DB2 acquires the rebind sequence lock. However, this lock may not get released after the statement is completed under certain circumstances and may lead to deadlock and concurrency issues with other statements attempting to rebind the same package. This lock would require the transaction to commit or rollback to get released. To confirm you're hitting this APAR, check the lock dumps for contention on the rebind sequence lock. For example, an application snapshot that shows the symptom: Application handle = 15486 Application status = Lock-wait Package name = P1593222409 Package name = SYSSH200 <corresponding statement from the applications that will on lock wait > ID of agent holding lock = 1124 Lock name = 0x97B2EF1B0000000001000062D3 Lock object type = Internal Sequence Lock Lock mode = Exclusive Lock (X) Lock mode requested = Exclusive Lock (X) This behavior can be seen starting from DB2 V10.1 FP2. | |
