2.5 user limits settings
在/etc/security/limits.conf中添加如下配置。
oracle soft nproc 4096
oracle hard nproc 16384
oracle soft nofile 10240
oracle hard nofile 65536
oracle soft stack 10240
oracle hard stack 10240
Add the following line to the "/etc/pam.d/login" file,
if it does not already exist.
session required /lib/security/pam_limits.so
session required pam_limits.so
Add the following to
/etc/profile if Oracle user will use the bash shell.
if [ $USER = "oracle" ]; then
ulimit -u 16384
ulimit -n 65536
fi
2.6 config enviroment variables
首先切换到oracle账户 ，编辑修改主目录下 .bash_profile
TMP=/tmp; export TMP
TMPDIR=$TMP; export TMPDIR
ORACLE_BASE=/u01/app/oracle; export ORACLE_BASE
ORACLE_HOME=$ORACLE_BASE/product/12.1.0/db_1; export ORACLE_HOME
