oracle数据库自动启动配置

前言

Oracle数据库默认情况下是不会随系统启动而启动的。在某些特殊情况下，有些用户希望可以自动启动，那么就需要手工编写相关的脚本来实现了。如下借鉴网络上的信息整理测试如下，经过测试可以正常运行。

Su -root 
1.
mkdir /home/oracle/scripts

2.
cat > /home/oracle/scripts/setEnv.sh <<EOF
# Oracle Settings
export TMP=/tmp
export TMPDIR=\$TMP

export ORACLE_BASE=/u01/app/oracle
export ORACLE_HOME=\$ORACLE_BASE/product/12.2.0.1/db_1
export ORACLE_SID=betadb

export PATH=/usr/sbin:/usr/local/bin:\$PATH
export PATH=\$ORACLE_HOME/bin:\$PATH

export LD_LIBRARY_PATH=\$ORACLE_HOME/lib:/lib:/usr/lib
export CLASSPATH=\$ORACLE_HOME/jlib:\$ORACLE_HOME/rdbms/jlib
EOF


3.
echo ". /home/oracle/scripts/setEnv.sh" >> /home/oracle/.bash_profile

4.

cat > /home/oracle/scripts/start_all.sh <<EOF
#!/bin/bash
. /home/oracle/scripts/setEnv.sh

export ORAENV_ASK=NO
. oraenv
export ORAENV_ASK=YES

dbstart \$ORACLE_HOME
EOF


cat > /home/oracle/scripts/stop_all.sh <<EOF
#!/bin/bash
. /home/oracle/scripts/setEnv.sh

export ORAENV_ASK=NO
. oraenv
export ORAENV_ASK=YES

dbshut \$ORACLE_HOME
EOF

chown -R oracle.oinstall /home/oracle/scripts
chmod u+x /home/oracle/scripts/*.sh


5.
You should be able to start/stop the database with the following scripts run from the "oracle" user.


$ ~/scripts/start_all.sh
$ ~/scripts/stop_all.sh




创建服务：
Create the service file called "/lib/systemd/system/dbora.service".

# systemd ignores PAM limits, so set any necessary limits in the service.

If you are using NFS storage, you need to define the dependency between Oracle and NFS.
