Re: MAXHANDS Attribute on the QMGR
On Friday we received a max channels error message. Instead of changing the qm.ini file and adding the CHANNELS stanza with the MaxChannels/MaxActiveChannels (we were using the default), the MQ admin simply increased the MAXHANDS attribute of the queue manager. This did resolve the problem. However, I am bit puzzled because while I can understand making more handles available to a queue manager might allow more Client channels to be started, why would MQ ignore the limits in the qm.ini file? Furthermore I thought MAXHANDS only applied to a single process. Any thoughts? PS: The version of MQ is old, 5.x (where x is less than 2). 11/19/04 14:02:56 AMQ9513: Maximum number of channels reached. EXPLANATION: The maximum number of channels that can be in use simultaneously has been reached. The number of permitted channels is a configurable parameter in the queue manager configuration file. ACTION: Wait for some of the operating channels to close. Retry the operation when some channels are available.

Re: DefaultQBufferSize and DefaultQFileSize
Does any know if these parameters are valid for MQ 5.3? If I specify DefaultQBufferSize, do I need to specify a value for DefaultQFileSize ? With a very high throughput of persistent messages (200 msg /sec), does anyone have a checklist of things to tweak for a queue manager?

Re: MQJMS2007 Message
Can anyone shed any light on the following scenario: We are doing a stress test with a JMS application and are getting a strange error message without any stack trace. The program works with a message length of 10,000 bytes but when we increase the message length to 315,000 we get this MQJMS2007 error message after putting 7 JMS messages to a destination. Has anyone seen this before?

Re: MQ Clustering Question
At the 'Application' level means the server in my scenario. What I am trying to achieve is this: If a back-end service running on a server is knocked out of the rotation (even though MQ might be OK), I want to: 1. Not send anymore messages to that instance (from the client) 2. Move the "stuck" message on that instance to another instance that is being serviced. I cannot afford for messages to get stuck for any period of time. PS: If a cluster queue is set to PUT(INHIBITED), on the server, will the WLM exit that IBM supplies recognize it when the client does the MQPUT (assume DEFBIND is NOT-FIXED)? Or, will the message travel down the channel to the cluster queue instance that was chosen, then the MCA will detect it when it tries to put the message to the chosen cluster queue? I know it will reroute it to another instance of the cluster queue, if one exist.

Re: Starting a 5.3 Queue manager
I am restoring a couple of queue managers in a cluster to physically different machines with different IP addresses. I still have the production cluster queue managers running (and there is connectivity between the two centers). I do not want any incoming or outbound channels to start if I bring up these queue managers for application testing.

Re: MQ Clustering Question
Thanks for answers to my prior question, especially Paul Clarke from IBM. I will definitely test out your suggestion Background In a cluster I can have cluster queues with the same name on multiple cluster queue managers. I need a way (at the application level) to NOT send messages to a specific cluster queue if the application servicing that instance dies/stops running etc. I don't want to write an exit. Question: Has anyone developed an elegant solution to this problem and would care to share it, on-line or off-line? My application cannot tolerate "stuck" messages.

Re: Trigger a Shell Script that starts a Java Program
I did some more testing and the queue in question is an error queue that can be written to by several applications. I tested a scenario whereby I used MQExplorer to put one message to the queue to trigger the script, then ran the other applications to generate additional error messages. In this scenario, only one instance of the Java program was sever started (IPPROCS=1). However, whenever triggering occurs because of error messages being generated by the applications themselves, multiple instances of the Java program gets triggered (IPPROCS > 1). This happens consistently.

Re: Trigger a Shell Script that starts a Java Program
We are running MQ 5.3 with CSD 6 on AIX. We have a scenario whereby we trigger a shell script then runs a Java program. The Java program has a wait interval of 1000 milliseconds and polls 50 times when the queue becomes empty (don't know why). If you put one message at a time on the queue, the started Java process will process all messages. However, if you were to put 60 (this is just an arbitrary number we are using at this time to recreate the problem), multiple Java processes are triggered off (the number is arbitrary). I have the TRIGINT set to 6 Milliseconds. This seems odd. I thought that if a queue had at least one process (Java or otherwise) that had it open for input, MQ would not generate another trigger message. Can anyone shed some light on what I am seeing?

Re: JMS and ReplyTo Function
Look at the MQ Using Java manual (page 196, SC34-6066-01). You have to use something that looks like URIs.

I can explain how it is supposed to work using the procedural terminology. The program does a MQOpen using the reply to queue and queue manager and MQSeries figures out it need to open and generate messages to a transmission queue with the same name as the ReplyToQueueManager. The problem is they are having problems translating that into object based JMS. They are calling some Sender method passing Destination or something. Any information on how JMS handles reply messages?

Re: AMQ7467 & 8 every 30 min
Part of the MQ logging algorithm is to take a checkpoint every 30 minutes, every 10,000 writes to the log file etc. So even if a queue manager is idle, I assume that a checkpoint would be taken every 30 minutes after the last checkpoint.

Re: MQ V5.3 GA1 and GA2 Version
In order to use BIG MQ as a JMS provider with WebSphere Application Server 5.0 (Network Version), the software prerequisite states that you need MQ 5.3 with CSD 1. Am I right in assuming that the October release of MQ 5.3 (mentioned as GA2 Version) is MQ 5.3 with CSD 1 applied? Or do I need to get CSD 1 and apply it to the October GA2 version?
