Linux hang when we install Oracle 10G and change sysctl.conf

[johnlee_dicko]

Hello,

Any one can help me !

We upgrade the oracle 9i to 10G and change the sysctl.conf. The Linux alway hang when we use "tar" to compress or decompress the large Oracle Database.

sysctl.conf

net.ipv4.ip_forward = 0
net.ipv4.conf.default.rp_filter = 1
net.ipv4.conf.default.accept_source_route = 0
kernel.sysrq = 0
kernel.core_uses_pid = 1

kernel.shmall = 2097152
kernel.shmmax = 2147483648
kernel.shmmni = 4096
kernel.sem = 250 32000 100 128

fs.file-max = 65536

net.ipv4.ip_local_port_range = 1024 65000

net.core.rmem_default=262144
net.core.rmem_max=262144
net.core.wmem_default=262144
