I created two databases on one server,db version:9.2.0.7.0
Red Hat Enterprise Linux AS release 4 x86_64 GNU/Linux
memory:16G
linux server sysctl.conf
kernel.core_uses_pid = 1
kernel.shmmax=8589934592
kernel.shmmni=4096
kernel.shmall=4194304
kernel.sem=250 32000 100 128
DB1:
sga_max_size 4297038336
shared_pool_size 570425344
db_cache_size 1677721600
DB2:
sga_max_size 8601448992
shared_pool_size 1073741824
db_cache_size 2147483648
DB1 sometimes appears the message:out of memory
How should I modify the parameters or increase the memory?
