## Avg User Wait Time For Task

Avg user wait time for task <task_ID>: <duration> ms, <number_of> waits, application pid <pid>

### Explanation

In a lock collision, the wait time for a lock to be released is quite considerable.

This can be caused by a transaction that takes too long. Long wait times (task status vwait) can also occur when various applications want to lock the same object.

If the locks are requested by other sessions, the database system attempts to execute locking tasks with higher priority within the database kernel.

For information on the current locks, see the system tables TRANSACTIONS and LOCKS of the database instance.

### User Response

Check the following aspects of the application:

- Is it suitable for isolation level 0 (uncommitted)?
- Can the time between the lock request and the COMMIT statement be reduced?
- Can you avoid simultaneous locks on the same row by splitting tables?
