Oracle Upgrade 10g to 12c Pre-upgrade checks

Hi All,

Afraid it's me again with yet another question.

I have just ran the pre-upgrade checks as per the Upgrade Guide for UNIX and am looking at the resultant log and output.

It's complaining about the processes parameter being too low.

                          [Pre-Upgrade Checks]

**********************************************************************

WARNING: --> Process Count may be too low

 

     Database has a maximum process count of 192 which is lower than the

     default value of 300 for this release.

     You should update your processes value prior to the upgrade

     to a value of at least 300.

     For example:

        ALTER SYSTEM SET PROCESSES=300 SCOPE=SPFILE

     or update your init.ora file.

I have checked this parameter against both the 10g note and the 12c note and both say the same thing to calculate as follows :-

So I double checked this and I get the following ABAP only,

16 WPs * 2  = 32

PARALLEL_MAX_SERVERS (CPU Core Count (12) * 10) = 120

+ 40

So I get 192 which is exactly what is set.

So why is it complaining about it needing to be at least 300?

Also things like events and _fix_control amongst others below should these be removed just prior to the upgrade or can these remain and be checked/removed post upgrade?

_disable_objstat_del_broadcast = FALSE

_external_scn_rejection_threshold_hours = 24

_first_spare_parameter = 1

_fix_control = 13627489:ON, 5099019:ON, 5705630:ON, 5765456:3, 6055658:OFF, 6399597:ON, 6430500:ON, 6440977:ON, 6626018:ON, 6670551:ON, 6972291:ON, 7692248:ON, 7891471:ON, 9196440:ON, 9495669:ON

_optim_peek_user_binds = FALSE

_optimizer_mjc_enabled = FALSE

_sort_elimination_cost_ratio = 10

Thanks
