Default Question about "shared read blocks" - 09-20-2011 , 02:19 PM






Hi,
I have a question about "shared read blocks". I have an application
that runs a transaction at isolation level=3. After the transaction
is run and committed, I am left with "shared read blocks" for the
tables that were updated in the transaction.

Why?

I checked the converted transaction log and I have commits for all the
transactions. (Below is the transaction log).

As it is the application is not working because if another user loads
a second instance of the application and tries to run the same
transaction it will fail. I need to close the original application
for the locks to clear.

The locks in sa_locks look like this after the transaction runs:

conn usrId table_name lock_type lock_name
32 DBA DBA.iInv S 25769948040
32 DBA DBA.iMaestro S 47244785050
32 DBA DBA.wFacts SP0000 107374857757
32 DBA DBA.wFactsXMes SP0000 180389300171
32 DBA DBA.wFactsXSemana SP0000 274878582002
32 DBA DBA.wMovimiento SP0000 30065445427

If I run the transaction again on the same connection, it works;
however,

I'm using 9.0.2.3687

Why do the shared read locks remain, in particular the SPD0000 types?,
and is there a way to clear them? I'm using an ODBC connection, and
the transaction is running on the client code.

Best regards,
Edgard
