Hello,

I am migrating the IIB server from solaris server to red hat linux server. Since we have maintain same fixpack level ( IIB v10.0.0.6) in both servers, i have used mqsiback and mqsirestore commands to export/import broker properties and deployable objects. That option worked well, however the interfaces are not working. while, i checked /var/adm/messages, i found exceptions on all msgsflows.

Currently, i have started the broker and facing "NoClassDefFoundError exception" for all the existing message flows.

result of echo $PATH, shows that it points to right java directory.

$ echo $PATH
/opt/IBM/mqsi/iib-10.0.0.6/common/jdk/jre/bin:/var/mqsi/extensions/10.0.0/server/bin:/var/mqsi/extensions/10.0.0/bin:/opt/IBM/mqsi/iib-10.0.0.6/server/bin/mosquitto:/opt/IBM/mqsi/iib-10.0.0.6/server/bin:/opt/IBM/mqsi/iib-10.0.0.6/common/node/bin:/opt/IBM/mqsi/iib-10.0.0.6/server/isadc:/opt/mqm/bin:/opt/IBM/mqsi/iib-10.0.0.6/tools:/opt/ActivePerl-5.10/bin/:/opt/ActivePerl-5.10/site/bin/:/usr/local/bin:/bin:/usr/bin:/usr/local/sbin:/usr/sbin:/opt/admin/bin:/ora/u01/oracle/v112/db1//bin

exception sample :-

Easy,

Delete the broker and recreate it from scratch including configured services by using the scripts you saved for doing so... You cannot use mqsibackupbroker and mqsirestorebroker across platforms...

Thanks for the reply.

I have deleted the broker and recreated it. Even then, i am unable to create any executiongroup. I have two iib version ( 10.0.0.6, 10.0.0.12 ) in the redhat server. But i am getting same exception in both fixpack versions.

i have resolved the above issue. Prime reason is to check the $PATH and $CLASSPATH variables.

The broker user was overriding the CLASSPATH and making it not able to find JRE path.

Now i have cleaned the unwanted variable from .profile and i can able to create EG under broker.


Thanks,
Karthik
