We have a complete AIX installation (middleware and collectors) running some years ago. Now, we need to monitor an Oracle DB on Solaris, and I would like to know if we can install a Solaris collector against the same existing middleware on AIX or we need to create a new middleware on Solaris. To summarize: should they (collector and middware) work on the same operating system, or can they be different operating system.
Having a Middleware and Collector on different Operating systems is fully supported
The middle-tier and Oracle host platforms are independent of one another.
For example, a middle tier can be running on Windows 2000 and an Oracle instance running on Windows 2003."
