We’ve built a Multi-instance Queue Manager environment using two Solaris SPARC 10 servers (server1 & server2) running MQ Server 7.0.1.6 in development.
Most of our applications have successfully tested automated failover, with either the MQSERVER variable or AMQCLCHL.TAB file containing the multiple hostnames as - server1(1414),server2(1414)
However, some of our Java apps do not seem to be able to specify the multiple hostnames. One application developer said that Jboss does not support Multi-instance Queue Manager.
Does anyone know if this is true?
Another Java app uses connection factories. I used JMSAdmin on his MQ Client server to create the connection factory with the multiple hosts, however, he does not want to have to manage connection factories on all of his MQ Client boxes. He wants to have it centralized to a JNDI server.
Can anyone offer any tips as to how to set this up?

I'd suggest you use a file based JNDI.
However using one JNDI with MI qmgrs can be a problem if you still have V6 code hanging around. The same for JBOSS. If all your MQ code there is V7 I do not see why it should not support multi-instance qmgr (that is if you are using a client connection). You do not expect JBoss to support an MI qmgr on a "bindings" connection now do you?

Using ./JMSAdmin, how do I define the QCF to connect to the multi-instance QM?
When I do the following, the app owner says his app can connect:
def qcf(aQCF_SERVER) qmgr(QM.SERVER.01) tran(client) chan(CH.SERVER.CLIENT) host(server1) port(1414)
when I try these, it does not work:
def qcf(aQCF_SERVER) qmgr(QM.SERVER.01) tran(client) chan(CH.SERVER.CLIENT) host(server1,server2)) port(1414)
def qcf(aQCF_SERVER) qmgr(QM.SERVER.01) tran(client) chan(CH.SERVER.CLIENT) connectionnamelist('server1(1414),server2(1414)'))

I would try moving the quotes.

Yeah, I tried a bunch of variations. I guess my main issue is, do I use the HOST and PORT or CONNECTIONNAMELIST in my DEF QCF command?
I tried using HOST and PORT on aQCF_SERVER and CONNECTIONNAMELIST on aQCF_SERVER1 below.
Note the HOSTNAME and CONNECTIONNAMELIST values on the defined QCF's
Basically, I want to wind up with CONNECTIONNAMELIST('server1(1414),server2(1414)')

I don't think you specify both host and connamelist.
But I'm kind of guessing here. |

I agree.
On my first def (aQCF_SERVER), I specified only HOST and PORT.
def qcf(aQCF_SERVER) qmgr(QM.SERVER.01) tran(client) chan(CH.SERVER.CLIENT) host(server1,server2) port(1414)
On my next def (aQCF_SERVER1) I specified only CONNECTIONNAMELIST
def qcf(aQCF_SERVER1) qmgr(QM.SERVER.01) tran(client) chan(CH.SERVER.CLIENT) connectionnamelist('server1(1414),server2(1414)')

I was able to change CONNECTIONNAMELIST using MQExplorer.
I am waiting for the app owner to test it out.

Well, it took it using MQExplorer. Until now, I've been using JMSAdmin command line.
Doesn't mean it's going to work. Once the app owner tests, I'll know.
If it fails, I'll try quotes.

Okay, got it working. App owners confirmed the connection to the first server and the ability to fail over to the second successfully.
Modifying it with MQExplorer worked. For some reason, using the JMSAdmin command line method, would not work for me.
Anyway, thanks all

So if it works without quotes, and you can't get JMSAdmin to accept it without quotes, then you can try escaping the ( and ) in the JMSAdmin command line.
i.e.
| Code: |
| def qcf(aQCF_SERVER1) qmgr(QM.SERVER.01) tran(client) chan(CH.SERVER.CLIENT) connectionnamelist(server1\(1414\),server2\(1414\)) |

No good.

hrm.
Well, maybe it's a forward slash or something else... might be worth a PMR if you were in the mood. |

have you tried
| Code: |
connamelist('server1(1414)', 'server2(1414)') |
?
