In "Timing setup" form,I have selected "worst" and "best" as Operating condition.
Warnings below ,however,came up when running "Timing Report" command.

WARNING : Operating condition worst does not exist
WARNING : Operating condition best does not exist
WARNING : Cannot set operating condition for the design.

My question is
1. What data or library should I prepare for setting Operating condition?
2. How to set operating condition for the design?

have you tried verify the existence of the 3 basic libraries: WC, NC and BC (Worst, normal and Best case). Those are PVT (process, voltage and temperature) variants of the same library and your vendor must provide it.

I don't remember the commands for astro. You can have a good help if access to solvenet (synopsis web help)
