Akash,
which phantom do you mean? If you do a "ps -ef | grep ds" you will see a number of processes, "dsapi_slave", "dscs", "dsrpcd" and a lock_daemon (I think). Since you refer to a phantom, I am assuming that you are looking at the Universe level, and a Phantom is the engine's definition of a background process. The process is a DataStage internal one.

"Phantom" is the term that DataStage uses to mean "background process" (in UNIX, they are specifically implemented as nohup processes so that they can continue to execute even though their parent process logs out).
Apart from daemons (executables such as dsdlockd, dsrpcd) and agent processes (dsapi_server and dsapi_slave), almost every DataStage process on the server will be a phantom.
Incidentally, the term "phantom" is the reason for the directory name &PH&. This directory contains the output from all phantom processes.
