Adrian Brock reassigned JBAS-1426:
----------------------------------
Assign To: (was: Adrian Brock)
> Changing readonly after autocommitt set to false fails with C-JDBC Driver
> -------------------------------------------------------------------------
>
> Key: JBAS-1426
> URL: http://jira.jboss.com/jira/browse/JBAS-1426
> Project: JBoss Application Server
> Type: Feature Request
> Components: JCA service
> Versions: JBossAS-4.0.1 Final
> Reporter: youngm
> Priority: Optional
>
>
> In the C-JDBC JDBC Connection driver it uses autoCommit=false to determine if
> it is in a transaction when changing readOnly.
> Unfortunatly LocalManagedConnection sets autoCommit=false prior to
> "checkState()" which synchronizes the readOnly property with the underlying
> connection. This approach works fine with most JDBC drivers with but not
> with C-JDBC. Looking at the JDBC 3 spec (10.1) JDBC says:
> "Typically, a new transaction is started when the current SQL statement
> requires one and there is
> no transaction already in place."
> The key word being "Typically". So it appears that it may be within C-JDBC's
> right to declare a transaction started once setAutoCommit=false.
> So, would there be any problem with changing LocalManagedConnection.begin()
> to call checkState() prior to setting autoCommit in the underlying connection?
