![]() ![]() I’m also available for consulting if you just don’t have time for that and need to solve performance problems quickly. I’m offering a 75% discount to my blog readers if you click from here. If this is the kind of SQL Server stuff you love learning about, you’ll love my training. The big question is: are you better off doing this in T-SQL than in your application? Waiting ~5 seconds (I know I’m simplifying here, and the deadlock monitor will wake up more frequently after it detects one) Normally when a deadlock occurs, one query throws an error, and there’s no attempt to try it again (unless a user is sitting there hitting submit until something works). This is a better pattern than just hitting a deadlock, or just waiting for a deadlock to retry. ![]() The catch block is set up to break if we hit an error other than 1222, which is what gets thrown when a lock request times out. While 5 milliseconds is maybe an unreasonably short time to wait for a lock, I’d rather you start low and go high if you’re trying this at home. WAITFOR DELAY '00:00:01.000' /*Wait a second and try again*/ de 2019 With SET LOCKTIMEOUT, we can set the maximum. You can read more on the MS SQL Server Lock Time-Out feature in the Microsoft documentation. Lock timeout sql server Error 1222: Lock request time out period exceeded: How to Web3 de feb. WHILE 1222 /*Lock request time out period exceeded.*/ Check the data source lockTimeout property at the level of the application server and make the change needed. Different LocksĪn alternative is to set a lock timeout that’s shorter than five seconds. ![]() The problem that may arise is when the deadlock monitor takes a full 5 seconds to catch a query, which can block other queries, and may generally make things feel slower. SQL Server error: The lock request time-out period has been exceeded.I’ll sometimes see people implement retry logic to catch deadlocks, which isn’t a terrible idea by itself. This example perfectly demonstrates and reproduces the problem As for the actual application Talend, it is unclear for what reason the transaction was not committed or rolled back. then you go to SSMs and look at the table and you'll encounter this "the lock request timeout period has been exceeded." (Microsoft SQL Server, Error: 1222) "error. Two: The SQL blocking statement actually led to the above "Lock Request time out period exceeded." (Microsoft SQL Server, error 1222) ".Īs for the above two problems, we can construct a case to see that the following steps can be used in testing the database test to re-make the error:Īs shown above, session 52 is in the sleeping state. Then there is only one possibility that the TRUNCATE statement is inside the transaction, and the transaction has not been committed or rolled back for logical reasons. It's strange that a truncate session is in the sleeping state, and this session is a request from a Linux server Talend application. One: The session ID 65 process is in the sleeping state, and the session is executing the TRUNCATE statement, supposedly truncate should be executed very quickly. ![]() In this case, there are two more confusing places: It blocks sessions with a session ID of 68 SET NOCOUNT on with tablesizestats as ( select Object_schema_name (ps.object_id, db_id (' ODS ')) as SCN-collate chinese_prc_ci_as, object_name (Ps.object _id, db_id (' ODS ')) as TB-collate chinese_prc_ci_as, Sum (ps.page_count) as pg from Sys.dm_db_index_physical_stats (db_id (' ODS '), NULL, NULL, NULL, ' LIMITED ') ps group by ps.object_id ) Insert into #tableNames (SCN, TB, seq, sampling) select & nbsp scn , tb , Row_number () over (Order by SCN, TB) as seq , CASE&NBSP &NBSP &NBSP &NBSP &N bsp when PG > 200001 then ' ten ' when PG between 50000 then ' 20 ' when Pg between 500 then ' + ' else ' + ' End from tablesizestats where (ABS (checksum (TB))% 1) = 0 This error is a bit strange, check the database server monitoring blocked alarm messages, found blocking alarm, I use the following SQL statement to view, as followsĪs shown above, a statement with a session ID of 65 executes TRUNCATE TABLE, which blocks sessions with session ID 60, while a session with a session ID of 60 is YOURSQLDBA updating statistics (Microsoft SQL Server, Error: 1222) ", as shown below, whether it is an account with general permissions or a login with the sysadmin role. (Microsoft SQL Server, error 1222) ", the corresponding Chinese error prompt is" the lock request time-out period has been exceeded. In SSMs (Microsoft SQL Server Management Studio), when you view the table for the database, you encounter the "Lock Request time out period exceeded. ![]()
