Dear All

I have a test standby database setup, which I have to shutdown every evening and start again in the morning. I use the following method for this
to startup

   sqlplus '/as sysdba'
     startup nomount
     alter database mount standby database
     alter database recover managed standby database disconnect from session;

and to shutdown

    sqlplus '/as sysdba'
    alter database recover managed standby database cancel;
    shutdown;

Is there any way I can automate these two processes

Thanks in advance

Saju

Write a script and put it in the crontab?

Thanks for the hint. I could do this using the following script
for startup

#!/bin/bash
ORA_HOME="/opt/oracle/920"
ORA_OWNER="oracle"
SQLCMD="sqlplus '/as sysdba'"
LOGFILE="strt.log"
cat startup.sql | su - $ORA_OWNER  -c "$SQLCMD" > $LOGFILE

startup.sql

startup nomount;
alter database mount standby database;
alter database recover managed standby database disconnect from session;

and for shutdown

#!/bin/bash
ORA_HOME="/opt/oracle/920"
ORA_OWNER="oracle"
SQLCMD="sqlplus '/as sysdba'"
LOGFILE="sht.log"
cat shutdown.sql | su - $ORA_OWNER  -c "$SQLCMD" > $LOGFILE

shutdown.sql

alter database recover managed standby database cancel;
shutdown;
exit

You have to explicitly set ORACLE_HOME and ORACLE_SID.
Don't "su" in your script, put the script in oracle crontab not root one then you just have to call "sqlplus '/ as sysdba' @startup"

Thanks Michel for your advice. But, if I put these scripts as cron entries for user oracle, how will it execute at system boot and shutdown?. If I am right, cron executes at preset timings and not at system startup and system shutdown. That is why I put these scripts in /etc/init.d/rc.n (n stands for runlevel).
