Enabling and Getting Trace file of a concurrent request

1) Enable Trace of a concurrent request:

Please enable trace on the concurrent program using the following steps: 
Go to Sysadmin > Concurrent > Program > Define 
Query the concurrent program 
Check the trace box to enable trace 


2) Fatching the trace file location:


The following query helps to identify the Trace file path location for a particular Concurrent Request

Pass the request id as parameter 

SQL Code:


SELECT
    req.request_id
    ,req.logfile_node_name node
    ,req.oracle_Process_id
    ,req.enable_trace
    ,dest.VALUE||'/'||LOWER(dbnm.VALUE)||'_ora_'||oracle_process_id||'.trc' trace_filename
