— sprawdzamy jakie wartości są w pamięci
[oracle@dbnod1 ~]$ cat /proc/sys/kernel/sem
250 32000 100 128
[oracle@dbnod1 ~]$ ipcs -ls

—— Semaphore Limits ——–
max number of arrays = 128
max semaphores per array = 250
max semaphores system wide = 32000
max ops per semop call = 100
semaphore max value = 32767

sysctl -w kernel.sem=”250 50000 100 200″

— wrzucamy do pliku
cat /etc/sysctl.conf | grep kernel.sem

— po zmianach:
