Script Component - Timeout Expired

Hello,

I have a script component inside one of my packages that performs a calculation on the fields and then does several insert statements on SQL 2005 database for each row inputed.

During the execution, when the data is a bit large ~ 3000 records input that produce around 20,000 insert statement, a "Timeout Expired" message pops up several times from the script component. Although the data enters in the database, but I have to manually click "ok" on each of the messages during run-time.
Any idea as to why I am getting this error or how to fix it?
Below is the code of the script component that does the insert.

Thanks for your help.

Part of Script Component Code:

Try

connMgr = Me.Connections.Connection

conn = CType(connMgr.AcquireConnection(Nothing), SqlConnection)

cmd.Connection = conn

cmd.CommandText = "INSERT statement .... "

If conn.State = ConnectionState.Closed Then conn.Open()

cmd.ExecuteNonQuery()

Catch ex As Exception

MsgBox(ex.Message)

End Try

Why are you doing this inside a script component? This is incredibly inefficient as it issues an INSERT for each of the rows. If you used the data-flow OLE DB Destination it would do set based inserts.

Hi Jamie,

For each row I have an amount, inception date and expiry date. I am using the script component because I have to divide the amount porportionally over each month between the inception - expiry dates and then issue an insert statement for each month with its amount. What I posted in my earlier question was the part that is doing the connection and insert because I thought there might be something wrong in it. So one row triggers multiple inserts depending on dates. I don't know how this is possible using OLE DB Destination.

Thank You,

Grace

How big is your cmd.CommandTimeout? Have you tried to set it to 0 to see whether that helps?

thanks

Yes I tried to set it to 0 but still the same error.

The full error message I get: "Timeout expired. The timeout period elapsed prior to obtaining a connection from the pool. This may have occured because all pooled connections were in use and max pool size was reached."

I tried to use conn.clearPool (conn) after the execution but get the message: "Timeout expired. The timeout period elapsed prior to completion of the operation or the server is not responding."

I tried to close the connection after the ExecuteNonQuery, it seems it worked, no more timeout expired. However, sometimes i get error on the DataFlow Task but when I run it another time, it works fine. I am still testing this case to know what is happening.

Thanks,

Are you trying to insert into a table that is also the target of an OLE DB Destination? If so, your timeout is probably due to a lock.

For the record, I think the OP would be better served sending the new rows to another output of the script and pushing them into an OLE DB Destination, rather than trying to do inserts in the script. It did not sound as if the original scenario was inserting to different tables, which is really the only reason (off the top of my head) to do it in the script.
