DISABLE DRM

Before 10.2.0.3, we should not use DRM. The main reason is that we have some issues fixed in 10.2.0.3.0 which cannot be backported to earlier versions.

To disable DRM the following parameters must be set on the instances:


- 10gR1
       _gc_affinity_time=0 
-  10gR2
       _gc_undo_affinity=FALSE
       _gc_affinity_time=0 

-  11gR2

       _gc_policy_time"=0

Disable read-mostly object locking
===================================
Run with "_gc_read_mostly_locking"=FALSE
