ORACLE随Linux开机启动

  ORACLE随Linux开机启动

        环境:VM+redhat9+oracle9.2

        1.修改/etc/oratab内容          ORACLE_SID:/u01/app/oracle/product/10.2.0/db_1:N改为如下内容
        # add below content
        #$ORACLE_SID:$ORACLE_HOME:Y
        demo:/u01/app/oracle/product/9.2.0:Y

        2.修改/etc/rc.local文件加以下内容          ####################################
        location :/etc/rc.local
        ####################################
        !/bin/sh
         This script. will be executed *after* all the other init scripts.
         You can put your own initialization stuff in here if you don"t
         want to do the full Sys V style. init stuff.
        touch /var/lock/subsys/local
        add below content
        su - oracle -c "/bin/sh /home/oracle/dbstart.sh"

        3 new file dbstart.sh vi /home/oracle/dbstart.sh的内容          export ORACLE_BASE=/u01/app/oracle
        export ORACLE_HOME=/u01/app/oracle/product/9.2.0
        export ORACLE_SID=demo
         start the listener
        /u02/oracle/ora/bin/lsnrctl start
        #start the db
        sqlplus "/as sysdba" <<eof
        startup
        exit
        eof

        问题：

        当开闭linux时，oracle也会关闭，对事务有哪些影响
