  1. Your Site is very informative and helpful. You are a master
    I just wanted know what is the actual command for “crs” as i dont see there is “CRS” command.
    Following is one of the example you are using to find the svc details, but i could not use this command
    I tried crsctl stat res -t /p etc., but couldnt get output what you get from this
    crs | egrep ‘hr.svc|NAME|—-‘

    Appreciate if you could help with this

    1. Hi,
      crs [ and crsi ] are both shell scripts to display the CRS status.
      You can download these scripts by using Menu Path
      RAC -> RAC Generic -> RAC Scripts
