OEJMX provides access to the stack information for a session by querying the AgentManager to find active sessions and then querying those sessions to generate a stack trace.
  1. Write a query to getSessionMetrics .
    Example: 
    
           {"O":"PASOE:type=OEManager,name=AgentManager","M":["getSessionMetrics","
           16952"]}
    Note: The query uses a specific AgentID, 16952 to return session metrics for a specific session.
  2. Save the query as getSessionMetrics.qry .
  3. Run the query using oejmx -Q /path/ getSessionMetrics.qry.
  4. Review the output in instance-name/temp/ getSessionMetrics-out- yyMMdd-HHmm .
    Notice that Session-7 is in ACTIVE state and still running some ABL code. 
    
           { "getSessionMetrics": { "AgentSession": [{ "SessionState": "IDLE", "ConnectionId": 
"org.codehaus.jettison.json.JSONObject$Null", "SessionMemory": 630630, "EndTime": "org.
codehaus.jettison.json.JSONObject$Null", "ThreadId": -1, "SessionExternalState": 0, 
"StartTime": "2018-07-30T15:18:28.736", "SessionId": 4 },{ "SessionState":
            "ACTIVE", "ConnectionId": 20, "SessionMemory": 1646192, "EndTime": "org.
codehaus.jettison.json.JSONObject$Null", "ThreadId": 6, "SessionExternalState": 0, 
"StartTime": "2018-07-30T15:18:28.736",
            "SessionId": 7 } ] } }
  5. Gather more information about "SessionId":7, run the following getSessionStacks query to get information about individual sessions and identify the running code.
    This collect the getSessionStacks details. 
    
           {"O":"PASOE:type=OEManager,name=AgentManager","M":["getSessionStacks", "
           16952","
           7"]}
  6. Save the query as getSessionStacks.qry .
  7. Run the query using the query oejmx -Q /path/ getSessionStacks.qry.
  8. Review the output in instance-name/temp/ getSessionStack-out- yyMMdd-HHmm .
    The output displays a list of the stack trace listing files that were in use by the session.
