Cannot connect to MQ series running on HP UNIX
Hi All,
I am unable to connect from my SCA application (running on Oracle Application server) to IBM MQ series queue manager running on HP UX. Are there any pre-requisites I should check on wrt IBM MQ?
I am using IBM MQ Series 5.3.
I have worked on WebSPhere Process Server with WebSPhere MQ 6.0 in the past and hadn't faced any problem. I just had to add the system userid (running WPS) to the mqm group on the machine running MQ series. That helped me smoothly connect to MQ using an Mq adapter (in WPS).
Pls suggest..
Regards,
Radha

That era of MQ adapter needs to allocate some storage in the application
server's address-space which it will be unable to do if you are using a
32-bit JVM and have set the JVM heap size to its maximum. The easiest
fix is probably to use the version 7 MQ java classes and connect as a
client.
If you wish to use a bindings mode connection, try reducing the JVM heap
size by at least 100 MBytes and try again.

Re: Cannot connect to MQ series running on HP UNIX
What were the error messages or error codes? What is in the MQ error logs on both sides?
BTW, MQ 5.3 is no longer supported by IBM. Please upgrade to 6.0 or 7.0.
