Hi Mark,
Thanks for the feedback. I tried...

SQL> alter session set "_smu_debug_mode" = 4;

Session altered.

SQL> exec dbms_transaction.purge_lost_db_entry('4.18.4935'); BEGIN dbms_transaction.purge_lost_db_entry('4.18.4935'); END;

ERROR at line 1:

ORA-06510: PL/SQL: unhandled user-defined exception
ORA-06512: at "SYS.DBMS_TRANSACTION", line 94
ORA-06512: at line 1

:-(

RE: lock held by in-doubt distributed transaction

I believe this is a bug. The first solution I saw was support telling people to convert their systems to using regular rollback segments but I believe that you can issue ' alter session set "_smu_debug_mode" = 4; ' to get around the problem. I do not have the bug number so before you alter your session you may want to check metalink on the hidden parameter. HTH -- Mark D Powell --

Subject: lock held by in-doubt distributed transaction

Hi folks,
One of our developers has just reported this error after a simple select:

select COUNT(*) FROM tracking.tracked_lacosa_request

ERROR at line 1:
ORA-01591: lock held by in-doubt distributed transaction 4.18.4935

So I looked for the in doubt transaction as follows:

select * from dba_2pc_neighbors;

and

select * from dba_2pc_pending;

but both returned no rows.

I tried the same query and also get the same error. I bounced the database (immediate) and still get the error and all the time with the same transaction id 4.18.4935. I got the developers to bounce their jboss

but no joy.

I tried dbms_transaction.purge_lost_db_entry:

SQL> exec dbms_transaction.purge_lost_db_entry('4.18.4935'); BEGIN dbms_transaction.purge_lost_db_entry('4.18.4935'); END;

*
ERROR at line 1:

ORA-30019: Illegal rollback Segment operation in Automatic Undo mode
ORA-06512: at "SYS.DBMS_TRANSACTION", line 65
ORA-06512: at "SYS.DBMS_TRANSACTION", line 85
ORA-06512: at line 1

Any ideas folks?

Cheers
Tony
