Multipe Connections at the same time possible?
Hi all, Need a clarification: When it says in the manuals that via a channel table your MQ Client app can connect to multiple qmgrs, does it mean that one connection or multiple connections at the same time? Also, on MQ server 5.3 on Windows NT server: If you have 3 qmgrs on the same machine, and your server app resides on that machine, can your server app connect to more than 1 qmgr at the same time (getting 3 HCONNs). I do not see any reason why multiple concurrent connections may not be possible, as you may be able to get multiple conn handles. But I just would like to confirm that... How is it on OS/390?

I should re-word this part: Also, on MQ server 5.3 on Windows NT server: If you have 3 qmgrs on the same machine, and your server app resides on that machine, can your server app connect to more than 1 qmgr at the same time -- if it knows the names of these queue managers (not via a channel table of course which is accessable only to clients).

Re: Multipe Connections at the same time possible?
Title: RE: Multipe Connections at the same time possible? you can certainly connect to as many qmgrs as you have and want. just need more handles open, and in the case of client, as many client connections defined. But it's not very common to connect to more than one qmgr at a time, although using client, you may need to connect to more than one qmgr. that's the convenience of using MQ client. cheers, Benjamin Zhou State Street. -Original Message- From: Ruzi R [mailto:[EMAIL PROTECTED]] Sent: Thursday, June 26, 2003 8:31 AM To: [EMAIL PROTECTED] Subject: Multipe Connections at the same time possible?

Ruzi, You cannot have more than one queue manager connected from the same application unless you are using threads. If you are using threads, then you can connect to more than one queue manager from within the same application process, but you need to do so in different threads and nota single one. Again you have to bear in mind that you cannot share Hconnsbetween threads.

Just a small clarification, my previous response was with reference to you being a serve app. Cheers Kumar ---Original Message--- From: MQSeries List Date: Thursday, June 26, 2003 11:03:57 AM To: [EMAIL PROTECTED] Subject: Re: Multipe Connections at the same time possible?

Re: Multipe Connections at the same time possible? A bit more info
There are two types of connections: client connections and server connections. You can do either from an application that runs on the same machine as the MQ server. On a machine without an MQ server you can only use client connections. Using server connections, an application can only connect to one MQ server at a time. Using client connections, an application can connect to multiple MQ servers--even if they are on the same machine as the application. -Original Message- From: Ruzi R [SMTP:[EMAIL PROTECTED] Sent: Thursday, June 26, 2003 6:48 AM To: [EMAIL PROTECTED] Subject: Re: Multipe Connections at the same time possible?

Dennis, Using server connections, an application can only connect to one MQ server at a time. If the App is threaded, can't each thread connect to a different qmgr at the same time?

Re: Multipe Connections at the same time possible? A bit more info
I believe V5.3 on NT differentiates applications at the thread level, so each thread can connect to a different qmgr. -Original Message- From: Ruzi R [SMTP:[EMAIL PROTECTED] Sent: Thursday, June 26, 2003 11:30 AM To: [EMAIL PROTECTED] Subject: Re: Multipe Connections at the same time possible?
