1. Check memory, at least 1G
grep memtotal/proc/meminfo

2. Swap partitions

Between 1 GB and 2 GB 1.5 times the sizeof RAM
Between 2 GB and GB Equal to the sizeof RAM
More than 16GB GB

grep "model name"/proc/cpuinfo
grep swaptotal/proc/meminfo

echooracle | passwd--stdin Oracle

9. Modifying kernel parameters

Shmmax-The maximum number of bytes in a shared memory segment, it is recommended to set a large point, even larger than the number of bytes in physical memory
Shmmin-The minimum size of the shared memory segment .
Shmmni-The maximum number of shared memory segments .
SHMSEG-The maximum number of shared memory segments that can be allocated per process .
Shmall-The maximum number of concurrent shared memory segments, larger than the SGA .
Semmns-The maximum number of semaphores associated with Oracle's process Count .
SEMMSL-The maximum number of semaphores in each semaphore set .

Vi/etc/sysctl.conf

Kernel.shmall= 2097152
Kernel.shmmax = 536870912
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
net.core.wmem_max=262144

Execute this command after modifying: sysctl-p

12. Modify Profile
if [$USER = "Oracle"]; Then
if [$SHELL = "/bin/ksh"]; Then
Ulimit-p 16384
Ulimit-n 65536
Else

13. Create a directory structure

Mkdir-p/u01/app/oracle/product/10.2/db_1
Chown-r oracle:oinstall/u01/app/
Chmod-r 775/u01/app/

14.

Vi/home/oracle/.bash_profile

Export Oracle_base=/u01/app/oracle
Export Oracle_home= $ORACLE _base/product/10.2/db_1
Export ORACLE_SID=ORCL
Export path= $ORACLE _home/bin: $PATH
