datastage command shell or dssh

Good afternoon

im new at datstage but i have some questions about it

when using dssh, what it is used for generally speaking?

1. can i connect to a teradatata database and make some querys?
2. if so, can i see teradata database sesions instead using Teradaata Manager?
3. can i kill database sesions instead of Teradaata Manager?

which are the pros and cons?
