Skgm warning

Question

Hello, I'm trying to decipher the following error message in
my ?/rdbms/ora_????.trc files:
/oras01/app/oracle/product/8.1.5/rdbms/log/ora_3580.trc
Oracle8i Enterprise Edition Release 8.1.5.0.1 - Production
With the Partitioning and Java options
PL/SQL Release 8.1.5.0.0 - Production
ORACLE_HOME = /oras01/app/oracle/product/8.1.5

I'd love to fix the shm parameters but I'm not sure what values
to change. The only kernel parameters I've changed are in the
following header files:
# diff shmparam.h shmparam.h.orig
36c36
< #define SHMMAX 0x5e28800 /* max shared seg size
(bytes) */
#define SHMMAX 0x2000000 /* max shared seg size (bytes) */
# cd ../linux
# diff sem.h sem.h.orig
66c66
< #define SEMOPM 100 /* ~ 100 max num of ops per
semop call */
#define SEMOPM 32 /* ~ 100 max num of ops per semop call */
The database starts up ok, and seems to be functioning normally,
but it still outputs this message. Any idea how to go about
fixing it?
Another, less troublesome, but still annoying message appears in
the alert logs:
Load Indicator not supported by OS !
Is there any way to make that one go away?

We have multiple instances running. Here is what our /etc/system file looks like if it helps....
* Lines below added for Oracle installation
*set shmsys:shminfo_shmmax=268435456
* Increase shmmax to fit more db instances
set shmsys:shminfo_shmmax=402653184
set shmsys:shminfo_shmmin=200
set shmsys:shminfo_shmmni=200
set shmsys:shminfo_shmseg=200
set semsys:seminfo_semmns=870
* set semsys:seminfo_semmns=500
set semsys:seminfo_semmni=500
set semsys:seminfo_semmsl=500
set semsys:seminfo_semmnu=500
set semsys:seminfo_semume=100
set semsys:seminfo_semmap=250
