RE: PTC Windchill

I do have PTC Windchill running at my site. The first thing I did when the database was "handed over to IT Operations" was to switch to ARCHIVELOG. [A year later, we had some problem with the I/O controller which corrupted the online archivelog file and also some of the files in the HotBackup-to-Disk. I had to restore the database from the previous night's backup and reapply the archivelogs till the last good archivelog. Potentially, we lost some data !]

As per the Site Info document that was provided by the Parametric consultants who did the implementation, we are running WindChill 5.0 which is NOT certified with 8.1.7. Yes, we are still running 8.1.6

The Windchill installation create's its own ORACLE_HOME and datafiles in a "database" directory under the ORACLE_HOME.

{A side note : Plumtree, BlueMartini and TivoliIdentityManager also create datafiles under $ORACLE_HOME/database or $ORACLE_HOME/dbs ! At least for these implementation, I am involved before they go live and either the consultant modifies the script to create the datafiles in the location I specify or I shutdown the database after the application installation and relocate the datafiles !}
