Oracle 19C RAC Database stop and start Step By Step process

 

Dear All,

In this post i am going to show you how to start and stop Oracle 19c RAC Database services including cluster services .

Check the db and grid background process status from putty ( backend ) 

ps -ef |grep oracle / ps -fu $USER  >> this will show you the all the process which are running under specific login user .

ps -ef |grep grid

ps -ef |grep d.bin

ps -ef |grep smon

Check the DB and Oracle Instance status from SQL prompt : 

select name,open_mode,instance_name from v$database,v$instance;

 

 

 

 Stop the database :: 

 

srvctl stop database -d RACSDB -o immediate

srvctl stop database -d RACSDB

 

Start and stop individual Instances : 

srvctl start instance -d RACSDB -i racsdb1

srvctl start instance -d RACSDB -i racsdb2

 

srvctl stop instance -d RACSDB -i racsdb1

srvctl stop instance -d RACSDB -i racsdb2

 

 Start and stop the cluster services :

Note : login to root user and go the grid home/bin path and execute below commands 

##cluster status 

./crsctl check cluster -all

./crsctl stat res -t

./crsctl check crs

##stop the cluster services 

./crsctl stop crs

##start the cluster services 

./crsctl start crs

 

crsctl check cluster -all

crsctl start res ora.crsd -init

crsctl check crs

./crsctl stat res -t

crsctl check crs

>>> Check Oracle High Availability Services On The Local Server.

crsctl stop crs

>>> Stop Oracle High Availability Services On The Local Server.

crsctl start crs

 >>> Start Oracle High Availability Services On The Local Server.

 

crsctl query crs software version

>>> Check Oracle Cluster ware Software Version

crsctl query crs active version

 >>> Check Oracle Cluster ware Active Version

crsctl query crs release version

>>> Check Oracle Cluster ware Release Version

 

 Thanks,
