Error: Number (1204) Severity (17). Running Out Of Locks

Sep 13, 2006

Hi,

First of all, my apology. I'm not sure if this is the right SQL server forum. Moreover, this didn't even happen on SQL Server but Sybase 11.9. But I'm thinking that the same situation might happen on SQL Server and I can't find any Sybase forum to run this by some experts.

I got the following error on a dev server:
Error: Number (1204) Severity (17). SQL Server has run out of LOCKS. Re-run your command when there are fewer active users, or contact a user with System Administrator (SA) role to reconfigure SQL Server with more LOCKS

The number of locks was set to 10,000.
I set it to 15,000 and ran the same code: Same error.
I set it to 20,000 and ran the same code: No error.
I set it back to 15,000 and ran the same code: No error.
I set it to 10,000 and ran the same code: No error.
I set it to 5,000 and ran the same code: No error.

It seems strange that it used not to work at 10,000 locks (repeatedlly) but once I set the number of locks to 20,000 once, then it worked with the number of locks as low as 5,000. Does anybody have any idea why this would happen?

Another question is that when the number of locks is set to 10,000, I run sp_lock while the code is running and the number of rows returned was often over 10,000. Still, I didn't get the error. Anybody knows why?

Did anybody ever run into a similar situation?

Appreciate your help.

SQL Server 2008 :: Row Locks Not Escalating To Table Locks After 5000

Jul 16, 2015

I've got an INSERT that's selecting data from a linked server and attempting to push 10 million rows into the blank table. More or less, it looks like this:

insert into ReceivingTable (
Field1, Field2, Field3, Field4
, Field5, Field6, Field7, Field8
, Field9, Field10, Field11, Field12
, Field13, Field14, Field15

[code]...

The instance of the SQL Server Database Engine cannot obtain a LOCK resource at this time. Rerun your statement when there are fewer active users. Ask the database administrator to check the lock and memory configuration for this instance, or to check for long-running transactions. There are no other active users. I ran it again and monitored the following DMO to watch the growth of locks for that spid:

SELECT request_session_id, COUNT (*) num_locks
-- select *
FROM sys.dm_tran_locks
--where request_session_id = 77
GROUP BY request_session_id
ORDER BY count (*) DESC

The number of locks started small and held for a while around 4-7 locks, but at about 5 minutes in the number of locks held by that spid grew dramatically to more than 8 million before finally erroring again with the same message. Researching, I can't figure out why it's not escalating from row locks to table locks at the appropriate threshold. The threshold in was set to 0 at first (Server Properties > Advanced > Parallelism > Locks). I set it to 5000, and it still didn't seem to work. Rewriting the INSERT to include a WITH (TABLOCK) allows it to finish successfully in testing. My problem is that it's coming out of an ETL with source code that I can't edit. I need to figure out how to force it to escalate to locking the entire table via table or server level settings.

A colleague suggested that installing service packs may take care of it (the client is running SQL Server 2008 R2 (RTM)), but I haven't found anything online to support that theory.

Transact SQL :: How To List All Locks (including NON-BLOCKING Locks)

Aug 5, 2015

We are migrating our database(s) from ORACLE to SQL. In Oracle we were able to issue a SELECT statement and see all of the locks (Blocking and Non-Blocking) currently in the system.  The query also included the Process ID of the process we needed to kill in order to get rid of the lock.

We now need to create the same type of query for Microsoft SQL Server 2012. I have seen postings on different sites saying that this info can be obtained using SP_WHO2 or using the SQL Server Management Studio Activity Monitor's PROCESSES tab, but we are looking for a SELECT statement that will give us similar information.

Locks

Nov 10, 2003

I have read that even during read procedures (sql select statements), sql server uses row locking. I know that you can use the NOLOCK keyword, but if you don't everytime that a user makes a selects statement on a table, does sql server really lock those rows, and if so are they then unavailable to another user who wants to make a select statement at the same time on that same table? That does not seem like it would be the case otherwise it would not scale well. Thanks for any clarification on this.

Feb 13, 2002

I am using SQL Server7.0. I opened a table through the Enterprise Manager and left it open. In the Query Analyzer when I try to update a field on that table(more than 2000 rows), it goes on running. When I watched the Current Activity, it shows that the update process is being blocked by the select query. But if I try to update the same column for less than 1500 rows, there is no blocking issue and the update occurs immediately. Can anybody let me know why this is happening and what should I do to prevent it?

2 quick questions :

1) How do I keep multiple users from editing the same record without locking the entire table? What would be a 'standard' way of handling this?

2) How do I keep 2 people from posting the same record?

Please help me understand locking, THANKS!!!

Locks For A Max Value

Apr 11, 2005

I have a stored proc which will be entering/updating a record into a table. The table's key is an integer field which I may have to increment by one. I know I can use

declare @nextid int
set @netxid = max(id) from table
insert @nextid into table
Is some kind of lock the best way to approach this?

Jun 16, 2004

Hello There !!

I have a very big problem, with SQL SERVER 2000. I want to know about the locks with select.

When I execute a Select (so big), and I try to update or Insert into one of the tables that I invoke in the select, I get locked.

Is there in SQL Server, something like a Select for update, that could be causing the problem ???

Is there any way to select rows from a table without locking it ?

I really have a big problem with this, and I don't know so much about sql server !

Thank you so much !!!

How To Reconfigure SQL 7 With More LOCKS

Oct 21, 1998

Hello to all!

I`m two weeks old with SQL 7 Beta 3 with no formal training whatsoever. I just kinda tinker with it at the moment since it`s installed in a stand alone server with me having sole access.

Using DTS (import into SQL), I tried to migrate an Inventory History dbf (Dbase 3) having 13+ million records. I got this error message after a few hours:

"Error at Destination for Row number 6353502. Errors encountered so far in this task: 1. SQL Server has run out of LOCKS. Rerun your statement where there are fewer active users, or ask the system administrator to reconfigure SQL Server with more locks."

It was the only application running on the server (aside from the SQL services) and i was the sole user. This is my first time on SQL Server and as DBA i should know everything `bout it.

Question is how and where do i reconfigure for more LOCKS? And how many LOCKS do i have to set?

Please help. Thank you in advance

It Can't Happen, SQL Locks Up

Dec 26, 1999

I am using SQL Server 6.5, when two or more independent applications put transactions through SQL, it locks up. Example of locks up.

When the OrderLines table is locked, then I put the following (Select * from OrderLines) then the query does not return any values, the world goes round and round, the only way out is to shut down and cross my fingers whilst SQL goes into recovery mode.

I have read through some of the documentation, such as deadlocks, livelocks and lock starvation but it say none of these will lock the whole machine. But somehow simultaneous transactions can, and the current activity dialog goes red, bright red.

Any ideas?

Row Vs Table Locks

Oct 10, 2003

I am interested in getting a better handle on how SQL 2000 determines the locking level to apply to different transactions. I am familiar with the fact that SQL does this on the fly but I was wondering if this could be specified in a Stored Procedure to use one over the other instead and what impact if any that might have on indexes. The databases I work with run anywhere from under 100 GB to 150 GB. Thanks for anyone's input on this subject.

Locks And Alerts

Nov 3, 2005

Hi,

I am having trouble with locks and performance issues in one application. The SQL server is specific to this application. What settings should i choose to set an alert to let me know when i get too many locks? the locks i am interested in ar ethe ones that show up in SQL EM. ie where a process is blocking another process(es).

I have tried New Alert | lock requests /sec but that is a huge figure when the server is running OK, so i cant guess what value to set for the counter. Is there a better object/counter i should use?

thanks

Understanding Sch-M Locks...

Sep 4, 2006

Hi Guys,
I have written quite a big stored procedure which creates a temporary table (multi-session) and updates it. All the statements are encapsulated in a single transaction which is explicitly declared in the code. What happens is that a lock is being put by the server on that table (of type Sch-M) in order thus preventing any type of operations on it (including simple select)

Now, I want to be able read that table from within another transaction. Why is that I cannot use a table hint NOLOCK in the select statement?

Here is some code which reproduces my problem.

Query A:



SET TRANSACTION ISOLATION LEVEL READ UNCOMMITTED;

BEGIN TRAN TR_DEMO;

CREATE TABLE ##TBL1(
Oidx int not null primary key identity(1,1),
Name nvarchar(30) not null,
Type char(1) not null
);


INSERT ##TBL1 (Name,Type) VALUES ('Car','M');

WAITFOR DELAY '00:00:10';

INSERT ##TBL1 (Name,Type) VALUES ('Plane','M');

WAITFOR DELAY '00:00:10';

INSERT ##TBL1 (Name,Type) VALUES('Submarine','M');

WAITFOR DELAY '00:00:10';

DELETE FROM ##TBL1;

DROP TABLE ##TBL1;

COMMIT TRAN TR_DEMO;



Query B:

SELECT TOP 1 * FROM ##TBL1 (NOLOCK) ORDER BY oidx DESC;

Launch query A and then execute query B.

Thanks a lot for your help.

Tempdb Locks

Dec 29, 1998

Good day.
I have a same problem with tempdb syscolumns locking. I call a
procedure thats creates a temporary tables fill its and try to insert a results into a table
which have a trigger which try to create a temporary tables.
Sometimes this work fine, but sometimes the server is hangs up. The sp_who shows next:

spid status loginame hostname blk dbname cmd
------ ---------- ------------ ------------------------------------ ----- ---------- ------------------------------------------------
1 sleeping sa 0 master MIRROR HANDLER
2 sleeping sa 0 master LAZY WRITER
3 sleeping sa 13 tempdb DUMP TRANSACTION
4 sleeping sa 0 master RA MANAGER
13 sleeping sa PROG1 0 SHOPNEW INSERT
14 runnable sa PROG1 0 master SELECT

The sp_lock procedure shows next:
............................ (I cut a big list)
13 Ex_page-blk 3 316 tempdb
............................

After that I can't make anything with hempdb (use sp_who2 or sp_lock2 or any other) and
can't a KILL 13. I also can't stop a service SQLServer.exe I can OLNY restart the NT...

Note: I tried to use a begin tran ... end tran. No effects reached.
And I can't understand why the server hang's up when he want...

I have a 20000 LE Threshold maximum.
