Ok... I have one of those pesky error, in an application not handling deadlocks or lockwaits.
The database object can't be modified to support deadlock/lockwatis... I can only change database parameteres Database info: Server version: 5.5.22-log Source distribution from show engine innodb status; {abstract} *** (1) TRANSACTION: TRANSACTION 5F7EA9A, ACTIVE 33 sec starting index read mysql tables in use 1, locked 1 LOCK WAIT 13 lock struct(s), heap size 3112, 27 row lock(s) update `account` set `balance`= 0.00 + '-6.07' where accountid='3235296' *** (1) WAITING FOR THIS LOCK TO BE GRANTED: RECORD LOCKS space id 5806 page no 69100 n bits 176 index `PRIMARY` of table `f_database`.`account` trx id 5F7EA9A lock_mode X locks rec but not gap waiting *** (2) TRANSACTION: TRANSACTION 5F7A398, ACTIVE 132 sec starting index read, thread declared inside InnoDB 500 mysql tables in use 1, locked 1 14 lock struct(s), heap size 3112, 27 row lock(s) MySQL thread id 92442, OS thread handle 0x7f903b949710, query id 32378480 90.0.0.51 mario Updating update `account` set `balance`= 0.00 + '-1.37' where accountid='3235296' *** (2) HOLDS THE LOCK(S): RECORD LOCKS space id 5806 page no 69100 n bits 176 index `PRIMARY` of table `f_database`.`account` trx id 5F7A398 lock mode S locks rec but not gap *** (2) WAITING FOR THIS LOCK TO BE GRANTED: RECORD LOCKS space id 5806 page no 69100 n bits 176 index `PRIMARY` of table `f_database`.`account` trx id 5F7A398 lock_mode X locks rec but not gap waiting *** WE ROLL BACK TRANSACTION (1) The issue is that I had a lock for over 132 seconds and the other was waiting for 33 seconds, so I get a lockwait. accountid is locked by a select balance from account where accountid='3235296' lock in shared mode How can I tell mysql to wait longer? I know the process which is doing the deadlock, is a long balance process... I know that it takes time, sometives over 15 minutes, but they always resolve... How Can I tell mysql to wait for the lock as needed? like for over 12 minutes? TIA
