How to disable auto startup of Grid and RAC Cluster and RAC database and tfa?

hi,

What is best and sound way to disable auto startup of Grid and RAC Cluster and RAC database and tfa?

There is no ASM used for database, just NFS/normal volumes.

I assume it's like this?

1)

--run for as oracle user, for disable database auto start.

srvctl modify database -d MYDB -y manual 

2)

--run for each RAC node as root user, to disable HAS (High Available Service) auto start.

/u01/app/19.0.0/grid/bin/crsctl disable crs

3)

-- fun for each RAC node as root user, to disable tfa (Trace File Analyzer) auto start.

/etc/init.d/init.tfa disable
