Oracle did not used to support that method of installing Oracle. There may also be issues with the Inventory. Why not just create a $ORACLE_BASE/product/9.2.0.6 directory. Install 9.2.0.1 into there and then upgrade it to 9.2.0.6. That can all be done well before the day o fthe migration.

Hi, You have to install 9201, and then upgrade it to 9206. But to shorten the downtime, you can pre-install such a copy on another host, make a tar file, copy it to the target box and relink it. all these can be done without affect existing instance. also edit listener.ora file and copy tns.ora On 7/14/05, Prem <premjhere@xxxxxxxxx> wrote: > Dimitre , > > I have to install 9201 and then upgrade it to 9206. > i cannot straightaway install 9206 .... isn't it ? > Hope you got me ! > can you tell me does it work ?
