Check for DB status and startup DB
EXPERTS,
I need a UNIX shell script to check the DBs status (Running/Shutdown) in the server.If its Running then no issue but if it is in shutdown state ,it should prompt like " DB is shut down you want to startup??" if i enter YES it should startup.
ORACLE_SID are present in /var/opt/oracle/oratab

Atleast need a logic to implement this..

Code:
check_stat=`ps -ef|grep ${ORACLE_SID}|grep pmon|wc -l`;
oracle_num=`expr $check_stat`
if [ $oracle_num -lt 1 ]
then
exit 0
fi

i tried this.. but the problem is ORACLE_SID is not set. the list of instances can be found in /var/opt/oracle/oratab.. i dont know how to proceed next..

Could you please how exactly the entries are there in oratab file? usually it will have ORACLE_SIDSmilieath at which oracle installed:shoudl it use db start or not (Y/N).

If you have multiple entries then you should know which SID you are searching for..

the problem is all of the below mentioned DBs will run on that server.if any one of DB goes down,i need to start up that particular DB.

Code:
ZBC102DI:/ora/product/v910:Y
ZBC112DI:/ora/product/v910:Y
ZBC122DI:/ora/product/v910:Y
ZBC132DI:/ora/product/v910:Y
#BUILDDB:/ora/product/v910:N
OMAGENT:/ora/product/omagent10g/agent10g:Y
