Hi all,

 We're  migrating to Solaris from Digital and I've found a problem with t
he
semaphores. As I'm trying to increase the processes more than 35 I get th
e
following error at starting up my instance:

ORA-07279: spcre: semget error, unable to get first semaphore set.
SVR4 Error: 28: No space left on device
Additional information: 1

The documentation recomends the following:
07279, 00000, "spcre: error semget, no se ha podido obtener el primer con
junto
de sem foros."
// *Cause:  An error occurred when trying to get first semaphore set.
// *Action: Check errno. Verify that system is configured to have semapho
res.
//          Verify that enough semaphores are available.  Additional info
rmation
//          indicates how many semaphores were requested.

In OSF had no problems with the default values for sempahores but we've c
hanged
the following values, indicating the rest as default:

set semsys:seminfo semns=120
set semsys:seminfo semmsl=50
set semsys:seminfo semmni=30
set semsys:seminfo semmap=30

We work with Oracle 7.3.4 in a Sun Enterprise 250 with Solaris 2.6

Any help would be greatly apreciated.
