Query regarding stopping of vcs

Hi Team,

 

Could you please suggest on this,

 

To stop the vcs and leaves the application running we use,

 

 hastop -all -force

and then start the vcs with hastart.

 

But, under which condition do we have to use  this command "hastop -all -force." when this operation  will require to keep the application running and do VCS stop and start.

When this is required to use " hastop -local " OR hastop -all to stop the VCS and application.

 

Please explain.

 

Thanks
