I've started with preparations for Oracle upgrade 10.2.0.2 of our test system which is complete homogenous system copy from production.
It's SAP R/3 4.6C with 4.6D_EXT supp. pack 2271, HP-UX 11.11 and Oracle 220.127.116.11
Following the Oracle Upgrade Guide_211, I'm on the point <b>4.1.6 Installing Required Interim Patches</b>.
Until now I have not installed any interim patch on Oracle 8 and 9i for our SAP system.
Is it really necesary to install all of the interim patches (depending on my environment) mentioned in the Note 871096 Oracle Database 10g Patch sets/patches for 10.2.0.???
Thanks in advance,
