Before You Begin Installing Oracle Database
Determine which versions of Oracle are supported for your application. See the software matrix (available from https://www.ptc.com/en/support/refdoc).
On UNIX systems, the installing user (including root) is typically the database administrator (DBA). It does not matter whether the user is a local user or Network Information Services (NIS) user.
When creating an Oracle database using PSI, you can launch PSI as the user that installed the database software, or as root user.
On Windows systems, the installing user needs to be a member of the Administrator 's group. It does not matter whether the user is a local user or a domain user.
You must have 5-GB of available hard drive disk space for an Oracle server installation with a Windchill demo database. More disk space is accordingly needed for larger databases.
For additional installation requirements, such as hardware and software prerequisites, consult the Oracle Help Center.
To complete the installation, you need to provide the installer with information. PTC recommends you gather this information in advance to allow the installation to proceed without interruption:
Name to assign to the listener.
Default is LISTENER.
Protocol type.
Default is TCP/IP.
Port number for the protocol type.
The default for TCP/IP is 1521.

To create a database using the PSI, the proper environment settings must be configured in a sh shell for an Oracle User. This includes updating the Oracle user profile so that the Oracle environment variable and path are set automatically when launching an sh shell. For more information see Database Configuration.
