Hallo I'm porting one Oracle Application to Postgres. This Programm uses "long living" Transactions. During the execution of transaction Nr:10295 (PID:18430) one new transaction with Nr:10339 (PID:18431) starts, that writes one record into the table. But this new transaction never stops, because it tries to set one ShareLock to its parrent transaction Nr:10295. My problem is, how can i found out - WHY the second transaction waits for end of first transaction? Is there a tool for analyzing such deadlocks? pg_lock output relation database transacti pid mode granted 251553 251331 18430 AccessShareLock t 251553 251331 18430 RowExclusiveLock t 251487 251331 18430 AccessShareLock t 251487 251331 18430 RowShareLock t 251487 251331 18430 RowExclusiveLock t 251492 251331 18430 AccessShareLock t 251494 251331 18431 AccessShareLock t 251434 251331 18434 AccessShareLock t 251407 251331 18431 AccessShareLock t 251434 251331 18430 AccessShareLock t 251429 251331 18430 AccessShareLock t 251548 251331 18430 AccessShareLock t 251548 251331 18430 RowExclusiveLock t 251575 251331 18430 AccessShareLock t 251458 251331 18430 AccessShareLock t 251524 251331 18434 AccessShareLock t 10293 18434 ExclusiveLock t 251482 251331 18430 AccessShareLock t 251482 251331 18430 RowShareLock t 251492 251331 18431 AccessShareLock t 251577 251331 18431 AccessShareLock t 251477 251331 18431 AccessShareLock t 251567 251331 18431 AccessShareLock t 251417 251331 18431 AccessShareLock t 251492 251331 18434 AccessShareLock t 1247 251331 18431 AccessShareLock t 16839 251331 18438 AccessShareLock t 251494 251331 18430 AccessShareLock t 251494 251331 18430 RowShareLock t 251494 251331 18430 RowExclusiveLock t 251434 251331 18431 AccessShareLock t 251553 251331 18431 AccessShareLock t 251494 251331 18434 AccessShareLock t 251392 251331 18431 AccessShareLock t 251472 251331 18430 AccessShareLock t 251472 251331 18430 RowShareLock t 251526 251331 18431 AccessShareLock t 251577 251331 18430 AccessShareLock t 251482 251331 18431 AccessShareLock t 251482 251331 18431 RowShareLock t 251472 251331 18431 AccessShareLock t 251472 251331 18431 RowShareLock t 251472 251331 18431 RowExclusiveLock t 251487 251331 18434 AccessShareLock t 251553 251331 18434 AccessShareLock t 251407 251331 18430 AccessShareLock t 251407 251331 18430 RowShareLock t 10381 18438 ExclusiveLock t 251487 251331 18431 AccessShareLock t 251487 251331 18431 RowShareLock t 251487 251331 18431 RowExclusiveLock t 251509 251331 18430 AccessShareLock t 251386 251331 18431 AccessShareLock t 251394 251331 18430 AccessShareLock t 10339 18431 ExclusiveLock t 251407 251331 18434 AccessShareLock t 10295 18430 ExclusiveLock t 251422 251331 18430 AccessShareLock t 10295 18431 ShareLock f _________________________________________________________________________ Mit der Gruppen-SMS von WEB.DE FreeMail können Sie eine SMS an alle Freunde gleichzeitig schicken: http://freemail.web.de/features/?mc=021179
