I am trying to use MR01 HA channel exit support pac from IBM to configure a sender channel from MQ to talk to a cluster on WebSphere Application server. IBM instructions to compile to the exit on Solaris 9 was to use CC. I do not have CC complier, hence i used GCC and the modified command is

gcc -D_REENTRANT -lthread -G -o/var/mqm/exits64/exits mr01exit.c -I/opt/mqm/inc -L/opt/mqm/lib64 -L/opt/mqm/lib64 -L/usr/lib/64 -lmqm -lmqmcs -lmqmzse -lsocket -lnsl -ldl -Bdynamic

Then i define in the channels defenition as

ALTER CHANNEL(BHMA.MQ.TO.WAS) CHLTYPE(SDR) MSGEXIT(exits) MSGDATA(/export/home/mqm/ExitConfig)

The channel failed with the following errors:

EXPLANATION:
This message applies to UNIX systems. The shared library
'/var/mqm/exits64/mrexit' failed to load as it is probably a 32-bit library, a
64-bit library is required. The following message gives details of the original
failure.
ACTION:
Supply the name of a 64-bit library.

AMQ6175: The system could not dynamically load the shared library
'/var/mqm/exits64/mrexit'. The system returned error message 'ld.so.1:
runmqchl_nd: fatal: /var/mqm/exits64/mrexit: wrong ELF class: ELFCLASS32'. The
queue manager will continue without this module.

EXPLANATION:
This message applies to UNIX systems. The shared library
'/var/mqm/exits64/mrexit' failed to load correctly due to a problem with the
library.

EXPLANATION:
Channel program 'BHMA.MQ.TO.WAS' ended because user exit
'/var/mqm/exits64/mrexit(ChannelExit)' is not valid.
ACTION:
Ensure that the user exit is specified correctly in the channel definition, and
that the user exit program is correct and available.

EXPLANATION:
Channel program 'BHMA.MQ.TO.WAS' ended abnormally.
ACTION:
Look at previous error messages for channel program 'BHMA.MQ.TO.WAS' in the
error files to determine the cause of the failure.

I re-compiled as a 64 bit, then tried it again. This time it gave the following errors...

04/25/08 18:21:14 - Process(883.1) User(mqm) Program(runmqchl_nd)
AMQ9002: Channel 'BHMA.MQ.TO.WAS' is starting.

EXPLANATION:

Can somebody give me some info on how to resolve this ? It will be really helpful thanks.

Thanks,
