Can someone advise me what am I doing wrong in following code that I get RC3047?
| Code: |
import java.io.*;
import java.util.*;
import com.ibm.mq.*;
import com.ibm.mq.pcf.*;
public class mqCheck {
public static void main (String [] args) {
//PCFMessageAgent agent;
PCFMessage request;
PCFMessage[] responses;
PCFMessageAgent agent = new PCFMessageAgent();
request = new PCFMessage(CMQCFC.MQCMD_INQUIRE_CHANNEL);
request.addParameter (CMQCFC.MQCACH_CHANNEL_NAME, "*");
int[] attrs = {CMQCFC.MQCACH_DESC,CMQCFC.MQCACH_MCA_USER_ID,CMQCFC.MQCACH_CHANNEL_NAME,CMQCFC.MQIACH_CHANNEL_STATUS};
request.addParameter(CMQCFC.MQIACH_CHANNEL_INSTANCE_ATTRS, attrs);
try {
agent.connect("192.168.1.153", 1414, "MQADMIN.MO71.SVRCONN");
System.out.println("Połaczono");
}
catch (MQException ex) {
System.out.println("A WebSphere MQ Error occured : Completion Code " + ex.completionCode
+ " Reason Code " + ex.reasonCode);
ex.printStackTrace();
for (Throwable t = ex.getCause(); t != null; t = t.getCause()) {
System.out.println("... Caused by ");
t.printStackTrace();
}
}
try {
// send the request and collect the responses
responses = agent.send(request);
for (int i = 0; i < responses.length; i++) {
// get the channel name and trim the spaces
String temp = responses[i].getStringParameterValue(CMQCFC.MQCACH_CHANNEL_NAME);
String channelName = temp.trim();
// get the channel description and trim the spaces
temp = responses[i].getStringParameterValue(CMQCFC.MQCACH_DESC);
String description = temp.trim();
// get the channel MCAUSER
temp = responses[i].getStringParameterValue(CMQCFC.MQCACH_MCA_USER_ID);
String mcauser = temp.trim();
// get the channel status
int chlStatus = responses[i].getIntParameterValue(CMQCFC.MQIACH_CHANNEL_STATUS);
System.out.println("chl: " + channelName + " status: " + chlStatus + "MCAUSER(" + mcauser + ")" + "DESC(" + description + ")");
}
}
catch (PCFException pcfEx)
{
System.out.println("A WebSphere PCF Error occured : Completion Code " + pcfEx.completionCode
+ " Reason Code " + pcfEx.reasonCode);
pcfEx.printStackTrace();
} catch (MQException ex) {
System.out.println("A WebSphere MQ Error occured : Completion Code " + ex.completionCode
+ " Reason Code " + ex.reasonCode);
ex.printStackTrace();
for (Throwable t = ex.getCause(); t != null; t = t.getCause()) {
System.out.println("... Caused by ");
t.printStackTrace();
}
}
catch (Exception e)
{
e.printStackTrace();
}
try {
agent.disconnect();
System.out.println("Rozłaczono");
}
catch (MQException e) {
// We'll silently ignore it in this demonstration program
}
}
}

3047 means MQRCCF_CFIL_PARM_ID_ERROR which means that you have an invalid parameter somewhere in a list. I suspect if you look at the rest of the information in the PCF response message that gave you that error it may also tell you the PARM_ID that was in ERROR.
However, without that information, and just guessing, I suspect you'll find that CMQCFC.MQIACH_CHANNEL_STATUS is not something you can inquire on CMQCFC.MQCMD_INQUIRE_CHANNEL. That parameter ID would be used on an MQCMND_INQUIRE_CHANNEL_STATUS command instead.
Cheers

Hi Morag,
Thanks for your reply, but I tried changing attrs list already leaving only CMQCFC.MQCACH_CHANNEL_NAME, but it didn't change anything, I still receive RC 3047 :/ |

Better look at the complete PCF response then and see what the queue manager thinks is the bad PARM_ID. Can you provide a browse of the reply message content perhaps so we can look at it?
Cheers
Morag

| Oh, sure, where can I find this PCF reply message? |

It's the message you are printing out the 3047 from.
You seem to have exception handling in there which you haven't showed us the output from - perhaps that contains what we need?

Hi,
Did you try our friend Mr. Google?
First off, you need a type, here is a simple setup:
| Code: |
request.addParameter (CMQCFC.MQCACH_CHANNEL_NAME, "*");
request.addParameter (CMQCFC.MQIACH_CHANNEL_TYPE, CMQXC.MQCHT_ALL );
request.addParameter (CMQCFC.MQIACF_CHANNEL_ATTRS, new int [] {CMQCFC.MQIACF_ALL} );
|
Regards,

Hi,
Yes sir. For several hours I was looking for working example but everything what I found was not working :/
Thanks a lot for your reply. My code is working now 
I don't like the documentation for MQ API. It doesn't show relationship between arguments, for example:
| Code: |
| request.addParameter (CMQCFC.MQIACH_CHANNEL_TYPE, CMQXC.MQCHT_ALL ); |
There is no information that CMQCFC.MQIACH_CHANNEL_TYPE can have CMQXC.MQCHT_ALL attribute. Or maybe I read it wrong :/
Next step is to display channel status. I assume I cannot do that within CMQCFC.MQCMD_INQUIRE_CHANNEL and I will have to use CMQCFC.MQCMD_INQUIRE_CHANNEL_STATUS for that for every channel from a list. |

You can use wildcard names for channel status too.
Just don't be surprised if some channels do not return a status. They are in "inactive" status and are fine.
Have fun

You can see the values that are expected here
where it shows:-
ChannelType (MQCFIN)
Channel type (parameter identifier: MQIACH_CHANNEL_TYPE).
If this parameter is present, eligible channels are limited to the specified type. Any attribute selector specified in the ChannelAttrs list which is only valid for channels of a different type or types is ignored; no error is raised.
If this parameter is not present (or if MQCHT_ALL is specified), channels of all types are eligible. Each attribute specified must be a valid channel attribute selector (that is, it must be one from the following list), but it might not be applicable to all (or any) of the channels returned. Channel attribute selectors that are valid but not applicable to the channel are ignored, no error messages occur, and no attribute is returned.
The value can be:
MQCHT_SENDER
Sender.
MQCHT_SERVER
Server.
MQCHT_RECEIVER
Receiver.
MQCHT_REQUESTER
Requester.
MQCHT_SVRCONN
Server-connection (for use by clients).
MQCHT_CLNTCONN
Client connection.
MQCHT_CLUSRCVR
Cluster-receiver.
MQCHT_CLUSSDR
Cluster-sender.
MQCHT_MQTT
Telemetry channel.
MQCHT_ALL
All types.
The default value if this parameter is not specified is MQCHT_ALL.

Thanks a lot for your feedback.
I use docs delivered with MQ client and this is a nightmare for me.
Morag, can you please give me a full link to online MQ API?
Thanks once again!
Cheers

Guys,
I moved one step forward with my tool, but what I dont understand now is why I get printed MQJE001 message everytime channel status is not found while this exception is handled by printing out "Channel status not found" in line 120 and I should not get any additional mesage for this exception.
Do you have idea why I get it?
Thanks a lot in advance!
