    ORA-01591: lock held by in-doubt distributed transaction

    Hi All,

    Got a mail from one of the developers that he is getting "ORA-01591: lock held by in-doubt distributed transaction 10.45.34659" error.

    The query he is running is just a simple update query connecting directly to the schema.

    update set =3134 where =1020 I have verified in dba_2pc_pending view and force rollback the transaction with the above ID and the issue is resolved.

    I am trying to understand why the simple update query is showing in distributed transactions? Appreciate your inputs.

    Thanks,

    ORA-01501 tells affected query found a locked resource - in this case I assume the updated table. Resource was locked by a dead distributed transaction.

    The simple "update" query did not cause the distributed transaction issue - it just happened to bump into a locked table.

    Thanks PAVB.

    Yes, I see some transactions in dba_2pc_table and rolled back those transactions to release the lock. I am trying to find from which dblink / machine those transactions are distributing. If you have some thing on your finger tips please share.

    Thanks,
