derby.locks.waitTimeout

Function

Specifies the number of seconds after which Derby aborts a transaction when it is waiting for a lock. When Derby aborts (and rolls back) the transaction, the transaction receives an SQLException of SQLState 40XL1.

The time specified by this property is approximate.

A zero value for this property means that Derby aborts a transaction any time it cannot immediately obtain a lock that it requests.

A negative value for this property is equivalent to an infinite wait time; the transaction waits forever to obtain the lock.

If this property is set to a value greater than or equal to zero but less than the value of derby.locks.deadlockTimeout, then Derby never performs any deadlock checking.

Default

60 seconds.

Example

CALL SYSCS_UTIL.SYSCS_SET_DATABASE_PROPERTY(
    'derby.locks.waitTimeout', '15')
derby.locks.waitTimeout=60
