Oracle RAC Database startup and shutdown ?

Описание: Hi everyone, In this video we'll learn about RAC (Real Application Cluster) and how to start and stop the DB, Cluster, CRS this steps often use in Production Deployments and needs to restart, shutdown servers at that time we do the steps.
Note:-
apologize guys for the audio...
some notes want to share like in oracle RAC db its the same database that has been distributed over a large number of servers. We can take example of single database has distributed over 100 servers, in this we assume punedb is database and pune1, pune2, pune3,...,pune100 are instance such that pune1 is on server1, pune2 on server2,..., pune100 is on server100,etc. this way RAC DB distribute and works it prevents downtime and increase availability for the users.

steps: Needs to be run on each node
Note: to find the bin directory path execute
$ ps -ef | grep d.bin
Note: to stop only instance
$ srvctl stop/start instance -d db_name -i instance_name
Note: to find db_name
$ cat /etc/oratab : below format oracle_sid = db_name
$ORACLE_SID:$ORACLE_HOME:Y/N

Shutdown the sequence
1) [oracle@server~]$ srvctl stop database -d your_db_name
2) [root@server bin~]# ./crsctl stop cluster -all
3) [root@server bin~]# ./crsctl stop crs

Startup the sequence
1) [root@server bin~]# ./crsctl start crs
2) [root@server bin~]# ./crsctl start cluster -all
3) [oracle@server~]$ srvctl start database -d your_db_name
