bove the amount of memory I can handle in my box, even with swap.
kernel.shmmax controls the maximum amount of memory to be allocated for shared memory which in this example is 2GB.
kernel.shmmni defines the maximum number of segments system-wide.
net.core.rmem_default and net.core.rmem_max define the default and maximum read buffer queue for network operations (1 MB in this example)
net.core.wmem_default and net.core.wmem_max define the default and maximum write buffer queue for network operations (256 KB in this example)
net.ipv4.ip_local_port_range tells the kernel the port ranges that will be used for outbound connections.
kernel.sem has four parameters:
cat /proc/sys/kernel/sem or ipcs -ls . On my machine, after the modifications on sysctl.conf , these commands output:# cat /proc/sys/kernel/sem 250 32000 100 128 # 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(I really don’t know if these are enough or too much, but I’ll keep you posted.) For a better understanding of these kernel-tweaking settings, I’d recommend these resources:
/etc/security/limits.conf , letting the oracle user use more resources than the defaults allowed. You may notice that all these values are a power of 2 minus one. When soft limits are exceeded, you’ll get a warning; the hard limits can’t be exceeded in any situation: you’ll get an error. I’m not completely sure, but I think these limits apply to each session/login (and since Oracle doesn’t exactly log in to the machine, my best guess is these limits apply per instance running).oracle soft nproc 2047 oracle hard nproc 16383 oracle soft nofile 1023 oracle hard nofile 65535Step Nine Make sure the limits.conf is being interpreted as the oracle user logs in by adding these lines to /etc/pam.d/login . You will want to make sure that is actually happening, since the defaults are way lower and you may get all sorts of problems.
拥有帝国一切，皆有可能。欢迎访问phome.netsession required /lib/security/pam_limits.so session required pam_limits.soStep Ten Unpack and prepare the installation. # cd /path/to/zipfile # unzip linux_11gR1b5_database.zip(And wait… wait a bit more… go get a cup of coffee…) After your second cup of coffee, you should have a multi-gigabyte set of files; this is our installer. # sudo chown -R oracle:oinstall database # sudo c |
