Short answer : many important parameters change. You must tune
ASE after the upgrade.

Long answer :

- "default data cache" must now be sized explicitly. Previously
it inherited whatever memory was left over in ASE after paying
for all other configurable parameters.

- "procedure cache percent" has been changed to "procedure cache
size", so it is configured in an absolute size rather than as a
percent of available cache memory. It must also be sized
explicitly.

- "number of engines at startup" is a new parameter. You must set
this equal to the value of "max online engines" or you will only
have one engine unless you manually bring others online.

Many new parameters have been introduced, some old ones retired,
and some changed. You will find this well documented in the
Sybase manual "What's New in ASE 12.5".

It's also important to make sure your operating system has all
patches required by ASE 12.5. (Particularly on Sun Solaris.) Read
the ASE 12.5 Release Bulletin for more details.
