RE: Distributed Transactions - Errors - In Doubt Transactions

Admin — Wed, 13 May 2009 04:07:16 GMT

If you see collecting:

SQL> select LOCAL_TRAN_ID,STATE from DBA_2PC_PENDING;

LOCAL_TRAN_ID STATE
---------------------- ----------------
3.70.1108483 collecting

then issue the following to fix it:

SQL> execute dbms_transaction.purge_lost_db_entry('3.70.1108483');

PL/SQL procedure successfully completed.

SQL> select LOCAL_TRAN_ID,STATE from DBA_2PC_PENDING;

no rows selected

Hi,

You Can try the following to rollback your transactions:
(It appears that you are seeing distributed transactions as Prepared instead of collecting.

Try running this:

SQL> select LOCAL_TRAN_ID,STATE from DBA_2PC_PENDING;

Then based on your results issue the following:

SQL> rollback force '[i][/i]';

SQL> commit;

SQL> alter system set "_smu_debug_mode" = 4;

SQL> exec dbms_transaction.purge_lost_db_entry('[i][/i]');

SQL> exit

You should repeat this for each entry that you get back from the first query.

Good luck.

Stacy

I noticed on google that someone received a similar message:

It looks like the user checked dba_2pc_pending and 1 record existing in that table and he gave rollback force. Even after that the record is there in dba_2pc_pending table.

Still no luck.

So I noticed the following in the alert log for which I have no clue on how to do .

The users were complaining that they had application issue but the database seemed to be fine and connections were ok and other users were ok but the distributed transactions were the ones having problems. I didn't know what to do.

Anyone have any clue ? I did a google search but no luck.
