Database Software

I have steps to stop the 10g RAC Database and clusterware but not sure about starting it.

I have heard executing

$crsctl stop crs --as root
on each node
will start the database,asm,nodeapps .Is that true?

or we have to do that step by step like we do in stopping the clusterware and database below

1.Stop the agent:
cd to $AGENT_HOME/corpng04.amhc.amhealthways.net/bin, then run: ./emctl stop agent

2.Stop the full database
$ oracle_home/bin/srvctl stop database -d db_name

3.Stop the ASM Instances on node1,node2
$ oracle_home/bin/srvctl stop asm -n node -- I guess you can't give multiple nodes in one command with comma,you need to give this multiple times with diff node name

4.Stop the NodeApps :vip,listener,oms and gsd
$ oracle_home/bin/srvctl stop nodeapps -n node -- I guess you can't give multiple nodes in one command with comma,you need to give this multiple times with diff node name


5.Stop the CRS cluster processes :those bloody 3 evmd,ocssd,crsd
$su - root
$CRS_home/bin/crsctl stop crs
