I have a requirement to build two servers in Amazon AWS hosted environment to host IBM's Websphere amd MQ instances.
1. Can these be built on Amazon OS 64 bit instances, or do they have to be built on RHEL ?
2. Can anyone recommend approximate file system sizes or point me to a how-to article to architect the sizes of logical volumes to allocate to these instances? I am just not sure how large to make the root file system and which directories to build as logical volumes, so the server does not run out of space down the road.
Here are recommendations I have found:
For Linux, the standard WMQ product binaries placement is in /opt/ibm/mqm while in AIX the product binaries are placed in /usr/mqm. The MQ instance and configurations is placed in /var/mqm.
As shown in the CPA's AIX filesystem partition above, the /var/mqm, /var/mqm/log, /var/mqm/errors and /var/mqm/qmgrs are placed in separated partitions. This is standard practices to allocate separate filesystems for logs and errors.
The partition sizes above are for your reference as the AIX WMB server serves a lot of applications, so the log and error directories are allocated a larger size for log keeping. You may not need 10GB for log space, but do provide ample of space for trouble shooting and it can fill up quickly.
Thank you for any insight in advance!
