1、記憶體管理，在該檔案末尾添加
/etc/sysctl.conffs.aio-max-nr = 1048576 fs.file-max = 6815744 kernel.shmall = 2097152 kernel.shmmax = 536870912 kernel.shmmni = 4096 kernel.sem = 250 32000 100 128 net.ipv4.ip_local_port_range = 9000 65500 net.core.rmem_default = 262144 net.core.rmem_max = 4194304 net.core.wmem_default = 262144 net.core.wmem_max = 1048576
# /sbin/sysctl -p
2、系統限制，開啟檔案數和進程數oracle soft nproc 2047 oracle hard nproc 16384 oracle soft nofile 1024 oracle hard nofile 65536 oracle soft stack 10240
3、env
su - oraclevi .bash_profileexport ORACLE_HOSTNAME=escmtest001 export ORACLE_BASE=/u01/app/oracle/ #跟後面設定的保持一致 export ORACLE_HOME=/u01/app/oracle/product/11.2.0/dbhome_1/ #跟後面設定的保持一致export ORACLE_SID=<sid> #大小寫都可以滴export PATH=.:$ORACLE_HOME/bin:$ORACLE_HOME/OPatch:$ORACLE_HOME/jdk/bin:$PATHexport LC_ALL="en_US" export LANG="en_US" export NLS_LANG="AMERICAN_AMERICA.ZHS16GBK" export NLS_DATE_FORMAT="YYYY-MM-DD HH24:MI:SS"
su - oracle
4、exit
vi /etc/hosts
add
