Re-installation of SP16 over SP15?

[Former Member]

I have done a few thing wrong with my database so I decided to re-install everything. Currently I have SP15, but SP16 is already available so I am downloading the latest version.

Can I simply install the new software over the existing version? Or should I first uninstall the previous version and clean up all folders?

btw, OS is windows.

Hi,

Which DB are you using? Did you mean upgrading EP SP15 to SP 16? If yes, I upgraded to SP 16 from SP15. I had Oracle 9 and OS - windows.

It worked for me only when i uninstalled prev versions and cleaned up all folders and began from scratch.

The steps i followed are:

1. Uninstall Oracle (your DB)(apply patches if necessary)

2. Uninstall WebAS

3. Install your database

Make sure important Oracle services are running.

4. Install WebAS SP (base) we had SP 9 CD

5. Install EP SP (base)- we had EP SP 9 CD

6. Import support package 16 for WebAS

7. Install EP SP 16

(Check if JAVA_HOME env var is set) and start the server in MMC console)

Hope it helps
