Transaction context in use by another session

问题

I have a table called MyTable on which I have defined a trigger, like so:

CREATE TRIGGER dbo.trg_Ins_MyTable
   ON  dbo.MyTable 
   FOR INSERT
AS 
BEGIN
    SET NOCOUNT ON;

    insert SomeLinkedSrv.Catalog.dbo.OtherTable 
        (MyTableId, IsProcessing, ModifiedOn)
    values (-1, 0, GETUTCDATE())
END
GO

Whenever I try to insert a row in MyTable, I get this error message:

Msg 3910, Level 16, State 2, Line 1 Transaction context in use by another session.

I have SomeLinkedSrv properly defined as a linked server (for example, select * from SomeLinkedSrv.Catalog.dbo.OtherTable works just fine).

How can I avoid the error and successfully insert record+execute the trigger?

回答1:

Loopback linked servers can't be used in a distributed transaction if MARS is enabled.

Loopback linked servers cannot be used in a distributed transaction. Trying a distributed query against a loopback linked server from within a distributed transaction causes an error, such as error 3910: "[Microsoft][ODBC SQL Server Driver][SQL Server]Transaction context in use by another session." This restriction does not apply when an INSERT...EXECUTE statement, issued by a connection that does not have multiple active result sets (MARS) enabled, executes against a loopback linked server. Note that the restriction still applies when MARS is enabled on a connection.

I solve It. I was using the same linked server to call the second procedure and then into the procedure I was using the same linked server.

It's very Easy, only we have to know the restricctions of linked servers.

回答3:

I have resolved it by removing linked server used in the stored procedure and then called stored procedure by the same linked server. It wasnt working in DEV environement.

回答4:

I also got the same error in our DEV environemnt, moving the linked databases to another sql instance resolved the issue. In our production environment these databases are already on separate instances

回答5:

In my case I was using SQL 2005 and got "transaction context in use by another session" when running Insert....exec over a linked server. The fix for me was to patch from SP2 build 3161 to SP3. SP2 cumulative 5 is supposed to fix though.

回答6:

When remote database sits on the same server,configure the linked server without specifying the database server ip / hostname and port. Just the database name should be sufficient.

回答7:

I was getting the same "transaction context in use by another session error" when trying to run an UPDATE query:

 BEGIN      TRAN
--ROLLBACK  TRAN
--COMMIT    TRAN
UPDATE  did 
SET     did.IsProcessed = 0,
        did.ProcessingLockID = NULL
FROM    [proddb\production].DLP.dbo.tbl_DLPID did (NOLOCK)
WHERE   did.dlpid IN ('bunch of GUIDs')
--WHERE   did.DLPID IN (SELECT DLPID FROM @TableWithData)

However I didn't realize I was already trying to run this on the DLP database on the ProdDb\Production server. Once I removed that "[proddb\production].DLP.dbo." prefix from the query, it worked fine.
