When you start up a database, it checks to see if there is at least the number of sems available as the number of max processes you are defining. If there isn't, it won't start. If you have other databases on the same host, be sure your total # of sems is greater than the sum of all the processes parms defined in all your init.ora's. As far as performance metrics... I can't speak to that, except, well do you really want 800 concurrent connections to your database??? If I ever get to that point I am going to implement MTS because it's going to be a nightmare when it does happen. I simply don't have the resources to support that kind of workload. Yet. HTH...

Subject: init.ora PROCESS parameter


Hi All,

Can anyone tell me, how does the PROCESS parameter in = the init.ora file
affect the performance of the database. I can't seem = to find any good
information
in the 8.1.6 documentation.

Database is MTS configured.

My 8.1.6 database init.ora has the following = options:

#processes =3D = 50           &nbs= p;           &nbs= p;           &nbs= p;           &nbs= p;        #
SMALL
# processes =3D = 100           &nb= sp;           &nb= sp;           &nb= sp;           &nb= sp;     #
MEDIUM
#processes =3D = 200           &nb= sp;           &nb= sp;           &nb= sp;           &nb= sp;     # LARGE

processes  =3D 800

What I have noticed is that, my database will not = startup if the process
value is greater
than 800.

Thanks for any help you can provide.
