The Solution Rating System

With so many solutions, how can you tell which solutions are most likely to help you and which ones are not? To provide you with a tool to use, we rate our solutions based on various elements that most accurately determine if a solution is a quality solution. To explain what factors affect the solution rating, here are the elements we take into consideration when formulating our solution rating.

The Grade of the Solution
The Zone Rank of the Expert Providing the Solution
The Number of Author and Expert Comments
The Number of Experts Contributing
The Feedback of the Community

Your Input Matters
Because of the way the system is set up, the most important variable in this equation is you. As a member of Experts Exchange, you are able to cast your vote on the quality of the solutions in regard to how complete, accurate, helpful and easy to understand each solution is. When you provide your feedback, each rating is adjusted accordingly. So, if you see a solution that has a poor rating that you think is a good solution, let us know by rating it. As you do, the rating will be adjusted and will become more accurate for other members of our site.

If you have any suggestions that you would like to make for our rating system, please ask a question in the Suggestions Zone of Community Support.

Thank you!

Maximum limit of Oracle sessions / processes in Oracle 9i & HP-UX kernel parameters required

Asked by sunhux in Oracle Database, Unix Operating Systems, HP-UX Unix

Tags: Maximum limit of Oracle sessions / processes in Oracle 9i & HP-UX kernel parameters required

Hi,

The link below said number 32000 is the max limit number of processes
that can be set in Oracle 10g :
http://forums.oracle.com/forums/thread.jspa?threadID=540004

The number of Oracle processes I'm referring to are illustrated below :
SQL>show parameter processes;

NAME TYPE VALUE
------------------------------------ ----------- -----------
. . . . . . .
processes integer 900

Q1:
What's the max value of Oracle processes/sessions that we can set for
Oracle 9i ( Version 9.2.0.8.0 ) ? (ie what's the max value for ??? in the commands :
SQL> alter system set processes=??? scope=SPFILE;
SQL> alter system set sessions=??? scope=SPFILE;

Q2:
On our HP-UX B11.11 with 4Gb RAM, our current sem* kernel
parameter settings are shown in bracketts below and it can
support up to about 1000 Oracle sessions and if we increase the
number of Oracle sessions much higher, we have to repair the
spfile.
My current values are indicated in bracketts below, so if I were
to increase them say by four fold, does that mean I can increase
the max limit # of Oracle sessions/processes in the same proportion,
ie
SQL> alter system set processes=4000 scope=SPFILE
New value I
plan to set to: (current value):
----------------- -------------------
semmni 8400 (currently 2000)
semmns 16800 (currently 2000)
semmnu 4196 (currently 1000)
