performance of 11.00 application on 11i

[Ian Lochray]

We produce an application compiled and linked on HP-UX 11.00. One of our customers is buying a new server that only runs 11i. Are there any performance implications of running an application built on 11.00 on a server running 11i?

[Rajeev Shukla]

Since its binary compatible so there shouldn't be any problem for an application running on 11 to run on 11i but for better performance its recommended you recompile it on 11i.

Rajeev,
I appreciate that it would be better if it was native but 99% of our customers want to stay on 11.00 for the moment and we do not want to support two different versions of our product. I am trying to get a feel for the size of any potential performance dergradation when running 11.00 code on 11i O/S.

Hi,

Most of the HP applications (compilers,DCE ...) for 11.0 also works on 11i.
so there shouldn't be any problem in running your application on 11i

See frankly i have copied the informix database(didn't install) and its running fine without any performance issues.
But to go more detail can you please tell what application they are. Are they C programs or 4GL etc.. Coz the memory allocation has definately changed a bit.

I am happy that the application will work on 11i, I am just concerned about any possible performance implications.

[Ian Lochray]

We have a large application consisting of about 20 executables and 40 shared libraries that uses Oracle 8.1.7 and is written using C, ProC and COBOL.

Hi,

If there are any implications, it's related to libraries
