Re: A program the uses MQSeries Client and Server libraries
The problem with VB is that you can't store pointers to functions and then call them in the same way you can from C. You could write a small DLL in C that provides the MQCONN etc. entry points and then calls the actual entry points in mqm.dll or mqic.dll based on the discussion below.

Re: A program the uses MQSeries Client and Server libraries
T.Rob, This is good advice and I agree whole heartedly that the application programmer must deal with 2009 reason codes correctly and perform message operations in syncpoint if you need to ensure 100% reliability. However, I do not agree that this is a client thing. Exactly the same decisions must be taken in the server application. There is no difference between the transactional programming model on the client and on the server. (except perhaps XA transactions and let's not start that debate). The only difference in the client is that the windows and opportunities for getting a 2009 are somewhat larger because you have a TCP socket in the way. Cheers, P.

Yes, it is true that you can write code that runs the same on client and server bindings. Just be sure to write the code to the more rigorous standards required for a client. Specifically, you want to do everything under syncpoint and figure out how to handle the 2009 return code. A 2009 means that your connection to the QMgr was lost. The problem is that you do not know whether it was lost BEFORE the MCA got your request or AFTER. So, for example, if you get a 2009 on a PUT, the call may have worked, or it may not. If you are making your calls under syncpoint you can be assured the PUT will be rolled back if you get a 2009. Under syncpoint, the only exposure is if you get a 2009 on a COMMIT. In this case, your messages MAY have been committed or MAY NOT. When your program reconnects, it has no way of knowing so you have to decide - do I redo any PUT and GET activity or not? If the application tolerates dupes well, you can just restart the previous transaction and repeat any PUT or GET activity. We found a bug under MQ 5.3 where the listener threw 2009 on a GET with convert but inetd handled it fine. This problem went away when we moved to the latest client. -- T.Rob -Original Message- From: Jeff A Tressler [mailto:[EMAIL PROTECTED] Sent: Tuesday, September 30, 2003 11:03 AM To: [EMAIL PROTECTED] Subject: A program the uses MQSeries Client and Server libraries We are writing a program that will be able to access either the MQSeries client or MQSeries server depending on the system it runs on.

Re: A program the uses MQSeries Client and Server libraries
bobbee, Like I said in my note I don't really want to get into an XA debate. XA is not *that* different from the single transactional case. If you lose your connection you will generally be backed out on the server. XA is two phase though and if you lose your connection after the 'prepare' phase then the server (ie MQ) can't arbitrarily decide to back it out. The coordinator must resolve the transaction the next time the server comes online. I don't understand your 'is there something I am missing' question. Do you have a specific question in mind ?

Re: A program the uses MQSeries Client and Server libraries
The Perl interface to MQSeries has to decide if it's running on a client or server machine. For Unix, the method it uses is to look for a directory named /var/mqm/qmgrs/@SYSTEM. If it exists, it's a server install, else a client install. For Windows, the code looks into the MQ portion of the registry (LocalMachine - SOFTWARE - IBM - MQSeries - CurrentVersion), and extracts the value of the FilePath key (often C:\mqm). It then looks for a directory named FilePath/qmgrs/@SYSTEM to decide whether it's running n a client or a server. Jeff A Tressler [EMAIL PROTECTED]To: [EMAIL PROTECTED] cc: Sent by: MQSeriesSubject: A program the uses MQSeries Client and Server libraries List [EMAIL PROTECTED] N.AC.AT 09/30/2003 10:02 AM Please respond to MQSeries List We are writing a program that will be able to access either the MQSeries client or MQSeries server depending on the system it runs on. My understanding is that the code can be written such that no changes are needed and the method of connection (Client or Server) depends upon which set of MQSeries libraries the program links with. This would create two different executable, one for a MQSeries Client system and another for a MQSeries Server system Is there a way to create a single executable which will recognize it is on a MQSeries server and perform accordingly and if not, perform as if it were running on a MQSeries client system?
