Hello, I think I asked that a question last month! We just went through this analysis for a new extremely important app (monetary transactions). IBM was a big help in helping provide the info necessary. While the decision wasn't my groups, I can tell you what the application considered.
MVS - established environment - production process such as monitoring/ops/perf tools/backup tools/security plans/etc all in place - difficult to get all the sw installed because hundreds of other apps are there (this is our env. - your z/OS may be far less complex :) and the cautious change environment - websphere code is "more different" from distributed environment - websphere seems to be built for unix then ported to MVS Linux on z - quick implementation (few days) - multiple instances easy to create for test/dev/production - not entirely est. in "production" support - extremely compatible with distributed environment in case we needed to move to faster blade processors It really came down to implementation time and commonality with distrib. systems giving z Linux the win - or at least a try for June with a Sept. production target. Hope that's useful. Do talk to your IBM folks - we've had great support from them.

Yeah, That's right. But given that same hardware resources are given to both the operating systems, what could be the factors ? I am able to think of the following factors : Positives : 1. Since Linux is an opensource, having WAS on zLinux will eliminate the workload licensing costs for z/OS because of WAS. 2. WAS for zSeries Linux is more advanced and may have features which are not there in WAS for z/OS 3. Performance of Java applications may also be better in zLinux Negatives : 1. Extensive debugging tools likes traces, logs, dumps which are there on z/OS may not be available for Linux for zSeries Regards, Srinivas.
