I need to get the numver of messages passes through the sonic queue per minute via a java code. I need this so i can create an alert when this messages per minute is higher than normal count. Can some on please assist me with this. Thanks
this information should be available via JMX (enqueued/dequeued count).
try to connect to the broker with VisualVM to find the ObjectName and Attributes.
to access sonicmq by JMX :
Hashtable env = new Hashtable( );
env.put(“ConnectionURLs", "tcp://localhost:2506");
env.put("DefaultUser", "Administrator");
env.put("DefaultPassword", "Administrator");
JMSConnectorAddress address = new JMSConnectorAddress(env);
JMSConnectorClient connector = new JMSConnectorClient( );
connector.connect(address);
ObjectName brokerName = new ObjectName(“Domain1.Container1:ID=Broker1”);
MBeanInfo mi = connector.getMBeanInfo(brokerName );
... usual JMX attributes access

Regarding: “Sending response back to the out/reply queue.”
There is a requirement to send the response back to a different queue (reply queue).
While sending the response, we have to use the correlation and message id from the request message and pass it to the reply queue as header. I suspect the format of correlation/message id is wrong.
While reading the message, the correlation id and message id format are as below:
MessageId = “ID:616365323063633033343361313165646139306638346264”
CorrelationId = “ID:36626161303030305f322020202020202020202020202020”
While sending the back to out/reply queue, we are passing these ids as below:
ITextMessage txtReplyMessage = sessionOut.CreateTextMessage();
txtReplyMessage.JMSMessageID = “616365323063633033343361313165646139306638346264”;
txtReplyMessage.JMSCorrelationID = “36626161303030305f322020202020202020202020202020”;
txtReplyMessage.Text = sentMessage.Contents;
txtReplyMessage.JMSDeliveryMode = DeliveryMode.NonPersistent;
txtReplyMessage.JMSPriority = sentMessage.Priority;
messagePoducerOut.Send(txtReplyMessage);
Please note:
With the XMS.NET library, we need to pass the correlation and message id in string format as per shown above
With MQ API’s (which we were using earlier) passing the correlation and message ids we use to send in bytes format like below:
MQMessage queueMessage = new MQMessage();
string[] parms = document.name.Split('-');
queueMessage.MessageId = StringToByte(parms[1]);
queueMessage.CorrelationId = StringToByte(parms[2]);
queueMessage.CharacterSet = 1208;
queueMessage.Encoding = MQC.MQENC_NATIVE;
queueMessage.Persistence = 0; // Do not persist the replay message.
queueMessage.Format = "MQSTR ";
queueMessage.WriteString(document.contents);
queueOut.Put(queueMessage);
queueManagerOut.Commit();
Please help to troubleshoot the problem.
Troubleshooting is a bit difficult because you haven’t clearly specified the trouble (is there an exception, or is the message just not be correlated successfully?).
In your code you have missed to add the “ID:” prefix. However, to address the requirements, you should not need to bother too much about what is in this field, because you simply need to copy one value to the other:
txtReplyMessage.JMSCorrelationID = txtRequestMessage.JMSMessageID
A bit unclear what the issue is. Are you able to run the provided examples in the MQ tools/examples? This approach uses tmp queues(AMQ.*) as JMSReplyTo
Start the "server" application first.
Request/Response Client: "SimpleRequestor"
Request/Response Server: "SimpleRequestorServer"
You can find the exmaples at the default install location(win):
"C:\Program Files\IBM\MQ\tools\dotnet\samples\cs\xms\simple\wmq"
The "SimpleMessageSelector" will show how to use the selector pattern.
Note the format on the selector: "JMSCorrelationID = '00010203040506070809'"

I need a cron job to obtain only the new emails received in a Exchange server since the last time it synchronized.
I coded the same with imap servers, and it was easy to get the emails since an ID. So I save the last ID at the end of the for cycle to the DB, and resume from that ID the next time the cron job executes.
I tried the same in Exchange, but I get the following error:
Failed to search for messages with "ErrorInvalidValueForProperty: El valor especificado no es válido para la propiedad."
To get the ItemId in Exchange I'm using the following code, with no error:
$item->ItemId->Id;
It returns something like:
AAMkADk3ZWRhY2VmLTdiY2UtNDkxYy04ZDMyLWZiZWIyYTQ4ZjQyMABGAAAAAAChH5wDkXAqTZaoH1oRodz8BwD8BvGliMkPTK/cnnmZJDPUAAAAvGXfAAD8BvGliMkPTK/cnnmZJDPUAAAAvJN5AAA=
To find the emails I'm trying the following code (with the error mentioned before):
$request = new FindItemType();
$request->ParentFolderIds = new NonEmptyArrayOfBaseFolderIdsType();
$request->Traversal = ItemQueryTraversalType::SHALLOW;
$greater_than = new IsGreaterThanOrEqualToType();
$greater_than->FieldURI = new PathToUnindexedFieldType();
$greater_than->FieldURI->FieldURI = UnindexedFieldURIType::ITEM_ID;
$greater_than->FieldURIOrConstant = new FieldURIOrConstantType();
$greater_than->FieldURIOrConstant->Constant = new ConstantValueType();
$greater_than->FieldURIOrConstant->Constant->Value = $UID;
Thanks!!
The EWS ItemId isn't a searchable property because it doesn't need to be eg you can just Bind to the Id in question to see if the Item exists. If it nolonger exists then you will get a specific error to tell you that. The SyncFolderItems operation is probably a more appropriate method to use however https://learn.microsoft.com/en-us/exchange/client-developer/web-service-reference/syncfolderitems-operation.
I am using MQ PCF to list authority records associated with a queue manager. Here is code.
PCFMessageAgent agent = new PCFMessageAgent(queueManager);
agent.setCheckResponses(false);
PCFMessage[] responses;
PCFMessage request = new PCFMessage(MQConstants.MQCMD_INQUIRE_AUTH_RECS);
request.addParameter(MQConstants.MQIACF_AUTH_OPTIONS,
MQConstants.MQAUTHOPT_NAME_ALL_MATCHING + MQConstants.MQAUTHOPT_ENTITY_EXPLICIT + MQConstants.MQAUTHOPT_NAME_AS_WILDCARD);
request.addParameter(MQConstants.MQCACF_AUTH_PROFILE_NAME, "*");
request.addParameter(MQConstants.MQIACF_OBJECT_TYPE, MQConstants.MQOT_ALL);
responses = agent.send(request);
This returns a huge number of authority records, most of these are standard/system records that MQ creates by default.
How do I change the above code (filter out default records) so that only the application specific authority records are returned?
request.addParameter(MQConstants.MQCACF_AUTH_PROFILE_NAME, "*");
You used a wildcard, so the queue manager will give you everything. Use "ABC*" to get ABC* only related authority records.
I need to setup a client which will send sqs to a server:
client side:
...
sqs = AWS::SQS.new
q = sqs.queues.create("q_name")
m = q.send_message("meta")
...
but how the server could read the message of the client?
Thank you in advance.
First you need to have your server connect to SQS then you can get your queue.
Do a get_messages on your queue. Go to boto docs to get more information on the attributes. This will give you 1 to 10 message objects based on your parameters. Then on each of those objects do a get_body() then you'll have the string of the message.
Here's a simple example in python. Sorry don't know ruby.
sqsConn = connect_to_region("us-west-1", # this is the region you created the queue in
aws_access_key_id=AWS_ACCESS_KEY_ID,
aws_secret_access_key=AWS_SECRET_ACCESS_KEY)
QUEUE = sqsConn.get_queue("my-queue") # the name of your queue
msgs = QUEUE.get_messages(num_messages=10, # try and get 10 messages
wait_time_seconds=1, # wait 1 second for these messages
visibility_timeout=10) # keep them visible for 10 seconds
body = msgs[0].get_body() # get the string from the first object
Hope this helps.
I am using IBM Websphere MQ. I have the queue manager and queue name. Now, I want to check whether the queue has any messages in it?
I did not work on this before. Pleas help
Please let me know if you need further information!
Thanks
The below code is .NET / amqmdnet - but you might try and convert this in the meantime until a Java dev sees your post.
To see if there is a message on the queue, without actually taking it off the queue, use MQC.MQOO_BROWSE on the Queue and IBM.WMQ.MQC.MQGMO_BROWSE_FIRST as the option
You'll get MQRC_NO_MSG_AVAILABLE if the queue is empty.
MQMessage queueMessage = new MQMessage();
MQQueueManager queueManager = new MQQueueManager(qmName, channelName, connName);
MQQueuequeue = queueManager.AccessQueue(qName,
MQC.MQOO_BROWSE + MQC.MQOO_FAIL_IF_QUIESCING);
MQGetMessageOptions opt = new MQGetMessageOptions();
opt.Options = IBM.WMQ.MQC.MQGMO_BROWSE_FIRST;
queueMessage.CorrelationId = IBM.WMQ.MQC.MQMI_NONE;
queueMessage.MessageId = IBM.WMQ.MQC.MQMI_NONE;
queue.Get(queueMessage, opt);
String sMessage = queueMessage.ReadString(queueMessage.DataLength);
To peek the next message use IBM.WMQ.MQC.MQGMO_BROWSE_NEXT;
To actually read the message OFF the queue, use MQC.MQOO_INPUT_SHARED on the AccessQueue.
The answer didn't show how to check for MQRC_NO_MSG_AVAILABLE. Here is my solution. If there are better ones please let me know.
try
{
queue.Get(queueMessage, opt);
String sMessage = queueMessage.ReadString(queueMessage.DataLength);
}
catch (MQException err)
{
if (err.ReasonCode.CompareTo(MQC.MQRC_NO_MSG_AVAILABLE) == 0)
return true;
}

It depends on where your queue manager is.
You could use MQUtilities - ih03 pack - which has rfhUtil.exe (Local Qm) and rfhUtilC.exe (for remote qm)
For Local QM , it is straight forward you need to place appropriate values and hit browse, it will show you Queue Depth.
For Remote QM, Place /TCP/(PortNo) for queue manager name and queue for queue name. Hit browse and you will get to know the queue depth.
For Unix/Ubuntu/Linux versions - There is a product called MQVisualEdit which is similar to this one.
