Re: OS/Hardware choice for Oracle Apps system

We are considering the move for the following reasons: With Linux could have multiple non-production versions of the Oracle Apps running. I believe you can do it on windows but concerned about the path settings, etc. Already running with /3gb and MTS since had hit 2G limit. Currently, we are running with 1.5G Priv Peak. Our SGA is undersized based on the 11i recommended parameters. >>> Mark Burgess <> 9/27/05 12:22:35 AM >>>

Hi Jeffrey,

first of all what would be the justification to move platform? Is it a resource issue on Windows or a move to have everything on the same platform as other systems? What is the usage of your apps install and the user base?

Unless you have a very large user population and need to run a very large SGA I would only consider a platform migration to 64-bit when your current hardware is at the end of its life. Going to a Linux/UNIX infrastructure will possibly make things like remote administration far easier and you would not need to run the MKS Toolkit for patching however there would be a significant time cost in the migration to do the export/import etc.

Like anything large change with apps a platform migration is a significant undertaking and would require alot of time and effort, particularly on the testing side and development side should you have a large number of interfaces into the system.
