FanDeZhi runs a more or less standard z/OS, so if you need to know what to find where, you should really look in the manuals. All of IBM's manuals are available on-line, at the IBM Library Server Library, so that should be your first, second and third port for call.
Likewise, if you get an error, you can look up the error message using IBM: LookAt - z/OS message help.
If you have a fast connection, you can actually download all 5Gb of manuals from IBM Online Library: z/OS V1R13 and Software Products DVD Collection, Sept 2012 (SK3T-4271-31).
