Hi,
first we when we started up with oracle we had problems with these params:
processes, open_cursors, max_enabled_roles
After a week or so oracle was not able to allocate shared memory,
something like this:
ORA-04031: unable to allocate 4200 bytes of shared memory (shared
pool,TRIGGER$,sga heap,state objects) ORA-00604: error occurred at
(remember I'm allways talking about Oracle under Linux)
This had 2 reasons:
1. wrong kernel-params (shared-memory-limits and semaphore-limits)
2. a memory leak in Oracle 8.1.7 (applying patchset 3 resolved this)
bye,

Hi Michael,
So what you are saying is that apache/php will keep opening sessions
until oracle runs out of processes or cursors or memory or hits
session_per_user maximum ??
I was thinking of experimenting with the profile parameter IDLE_TIME
Profile Parameter to make oracle close open sessions after a certain
amount of time , have you any experience with this?
I have
open_cursors = 500
processes = 200
max_enabled_roles = 30
regards
Steve

Hi,
this depends on your settings in the initinstance.ora in the
directory /opt/oracle/OraHome1/admin/instance/pfile dir.
Here are some settings:
processes = 150
open_cursors = 300
max_enabled_roles = 30
you also have to set the sizes of the shared-memory pool.
bye,

Hi all,
Does anyone know how many sessions can be opened by apache/php to
Oracle using OCIPlogon, or what parameter setting controls this?
TIA
Steve
