Am trying to write java program to read and parse activity report.
It will be helpful if anyone can guide me to apis and preferably a sample Activity report reader and parser code 
From documentation Activity report consist of
1 MQMD
2. Data:
2.1 MQEPH (embedded PCF header)
2.2 report data
But, there has to be a parent to have MQMD and DATA inside that parent. What is that? What is the starting point.
Help appreciated!! |

Hi java_problem, fjb_saper, all
I am trying to read the activity report. Got the activity report structure at
http://publib.boulder.ibm.com/infocenter/wmqv6/v6r0/index.jsp?topic=/com.ibm.mq.csqsav.doc/csqsav0464.htm
and further details at
http://publib.boulder.ibm.com/infocenter/wmqv6/v6r0/index.jsp?topic=/com.ibm.mq.csqsav.doc/csqsav0464.htm
documentation says
Activity reports are standard WebSphere MQ report messages containing a message descriptor and message data. Activity reports are PCF messages generated by applications that have performed an activity on behalf of a message as it has been routed through a queue manager network.
In the same line Activity report is considered as standard report message and also PCF message. Confusing ...
I was able to read activity report and get header information using
| Code: |
MQQueue queue = qm.accessQueue (qName, MQC.MQOO_BROWSE | MQC.MQOO_FAIL_IF_QUIESCING);
MQMessage message = new MQMessage ();
MQGetMessageOptions gmo = new MQGetMessageOptions ();
gmo.options = MQC.MQGMO_BROWSE_NEXT | MQC.MQGMO_NO_WAIT | MQC.MQGMO_CONVERT;
message.messageId = null;
message.correlationId = null;
queue.get (message, gmo); |
and then got header information by message.
So that means activity report is a normal message since I the code didnt threw any exception.
However for statement
| Code: |
| PCFMessage pcf = new PCFMessage (message); |
I got QJE001: Completion Code 2, Reason 3001: MQRCCF_CFH_TYPE_ERROR
that means atleast PCFMessage is not the way to parse it..
Now considering the activity report is a normal MQMessage then getting to its data section is trickier...
documentation says activity data has 2 parts-
1. Embedded PCF Header MQEPH and
2. Activity Report Message Data itself - this inturn has MQMD and Embedded MQMD.
I am not able to get any clear documentation for parsing these... or any guide on parsing the information....
it will be helpful if anyone can provide sample code or guide or link to some clue towards this... even anything which can help me understanding parsing of data....
appreciate quick help!!
thanks |

Also the standard util code
| Code: |
import com.ibm.mq.*;
import com.ibm.mq.pcf.*;
import java.io.*;
public class ReadPCFMessages
{
public static void main (String [] args)
{
int messageCount = 0;
try
{
MQException.log = null;
MQQueueManager qm = new MQQueueManager (args [0]);
MQQueue queue = qm.accessQueue (args [1], MQC.MQOO_BROWSE | MQC.MQOO_FAIL_IF_QUIESCING);
MQMessage message = new MQMessage ();
MQGetMessageOptions gmo = new MQGetMessageOptions ();
gmo.options = MQC.MQGMO_BROWSE_NEXT | MQC.MQGMO_NO_WAIT | MQC.MQGMO_CONVERT;
while (true)
{
message.messageId = null;
message.correlationId = null;
queue.get (message, gmo);
// Parse the message content using a PCFMessage object and print out the result.
PCFMessage pcf = new PCFMessage (message);
System.out.println ("Message " + ++messageCount + ": " + pcf + "\n");
}
}
catch (MQException mqe)
{
if (mqe.reasonCode == MQException.MQRC_NO_MSG_AVAILABLE)
{
System.out.println (messageCount + (messageCount == 1 ? " message." : " messages."));
}
else
{
System.err.println (mqe + ": " + PCFConstants.lookupReasonCode (mqe.reasonCode));
}
}
catch (IOException ioe)
{
System.err.println (ioe);
}
catch (ArrayIndexOutOfBoundsException abe)
{
System.err.println ("Usage: java " + ReadPCFMessages.class.getName () +
" local-queue-manager-name queue-name");
}
}
} |
works for Reading PCF messages including administration, event, accounting and statistics messages.
When code ran on SYSTEM.ADMIN.ACTIVITY.QUEUE got MQJE001: Completion Code 2, Reason 3001: MQRCCF_CFH_TYPE_ERROR
seeking clues !!!
