Hi,

We are doing test upgrades for EBS R12.2.4.    Source is 11.5.10 cu2  .    We have the following hardware in Red hat linux 64 bit

DB  :  8 cpu cores /64 GB memory

APP tier : 8 cpu cores /32 GB memory.

Based on the above information what is the optimum number of workers , I can use.    I am currently using 16 workers.  Can I increase this number ?     Also , what are the db parameters , I should set for the upgrade

db_multiblock_read_count -- disabled

parallel_max_servers =    16   (2X cpu cores)

job_queue_processes = 8  ( equal to number of cpu cores)

Also, I have enabled hugepages.

I have set all other parameters as per recommended list .
