[jira] [Commented] (DERBY-1016) javax.transaction.xa.forget (Xid)
raises XAER_NOTA exception instead of XA_PROTO on a prepared transaction
[ https://issues.apache.org/jira/browse/DERBY-1016?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13118609#comment-13118609 ]
Jayaram Subramanian commented on DERBY-1016:
--------------------------------------------
Hi
1) In the attaced test case suite, should we add a case for XAER_NOTA scenario
2) In the atttached test case should we test for a positive scenario where XA_FORGET goes through without any issues
3) Also in simillar lines should we test how XA_FORGET behaves after a commit or rollback.

> javax.transaction.xa.forget (Xid) raises XAER_NOTA exception instead of XA_PROTO on a prepared transaction
> I posted a question to derby-dev about this and heard no response so am assuming it is indeed a bug.
> in the XA+
> specification, it seems like xa_forget should only be valid for a
> heuristically completed transaction, so should be XAER_PROTO
> and not XAER_NOTA.
> In xaStateTran.sql we have this case:
> -- get back into prepared state
> xa_start xa_noflags 50;
> insert into xastate values(2);
> xa_end xa_success 50;
> xa_prepare 50;
> select * from global_xactTable where gxid is not null order by gxid;
> -- the following should error XAER_NOTA
> xa_forget 50;
> The user code I am looking at handles forget like this. They expect
> XAER_PROTO in this case.
>
> try {
> xaRes.forget(xidList[i]);
> System.out.print("XA-Transaction [" + (i+1) + "]
> Forgotten. \n" );
> } catch (XAException XAeForget) {
> if ( XAeForget.errorCode ==
> XAException.XAER_PROTO ) {
> System.out.print("XA-Transaction [" + (i+1)
> + "] not heuristically completed yet - Rolling Back instead. \n" );
> xaRes.rollback(xidList[i]);
> System.out.print("XA-Transaction [" + (i+1)
> + "] Rolled Back. \n" );
> }
> if ( XAeForget.getMessage() != null ) {
> System.out.println("XAException " +
> XAeForget.getMessage() );
