ORA-00060 Deadlock while waiting for resource

Posted on Aug 15, 2016 at 12:07 PM 835 Views

Hi Experts

We have only 12 hours per day for execute our data loading job in SAP BW. But

Every parallel job for data loading is stop with following error:

ORA-00060 Deadlock while waiting for resource

1st we try 8 parallel jobs with 50K packet size, it stop after 9.5 hours when 80% data load.

2nd we try 6 parallel jobs with 50K packet size, it also stop after 12 hours when 80% data load.

If we reduce parallel jobs then it may be take more then 12 hours which is not allowed by basis.

Our DBA doesn't figure out what is the solution. so what is you advice to rectify this issue??

Thanks

    You should ask the DBA's to investigate the Oracle alert log and the traces files when this error appears.

    hi Imran,

    First we need to find out if it is database deadlock or application deadlock. If it is database lock, then we need to adjust initrans, maxtrans.

    If it is application deadlock, needs to involve BW consultant. For the details, please check SAP note 84348.

    Best regards,
    James

      Hi Irman,

      Sorry, I only saw part of the graph.

      In this case, you need to adjust initrans, maxtrans.

      You can use brspace to do this, please see Lars doc:

      Quick help for ORA-60 deadlock in BW systems


      Before changing it, you need to check its current values:

      SELECT partition_name, ini_trans, max_trans FROM

      dba_tab_partitions

      WHERE table_name = '<TABLE NAME>'

      AND table_owner = '<OWNER>';


      Or you can use sqlplus command to adjust them as mentioned in the SAP note 84348 , but afterwards you have to reorganize the table manually to take the new value effect.

      Best regards,
      James
