I am looking for information regarding upgrading to Oracle 10g from Oracle 9i. We plan to keep the infrastructure constant (HP-UX), but would like to know the impact this would have in terms of memory utilization. Will Oracle 10g require more resources? Is there a method for determining what this increment would be?

Oracle's Technology Network has a wealth of information with respect to upgrading your database to Oracle 10g. The Oracle Database Upgrade Guide 10g Release 2 (10.2) can provide some information about how to migrate a database to 10g.

Another good reference is the Oracle Database Installation Guide 10g Release 2 (10.2) for HP-UX PA-RISC (64-Bit).

Finally, it is a good idea to review the Oracle Database Release Notes 10g Release 2 (10.2) for HP-UX PA-RISC (64-Bit).

If you have a Metalink account, there are also a number of up-to-date articles regarding Oracle 10g on the HP-UX platform.

A final thought would be to remember that migrating a database to a new release requires testing … a lot of testing. You must be prepared to test this migration a number of times prior to doing this in a production environment. And remember that testing requires time and effort from your application support folks and business users; this activity cannot happen in isolation for it to be successful.
