First time trying to use MySQL on NOWS SBE 2 (SLES 10 sp1). NCP prosix is working OK.

General questions:
1.Where is the documentation about the specific installation of the MySQL on SLES 10?
2.Do I need to the any specific post installations actions for the first time I use MySQL on a new server?
3.How can I check if MySQL is already running?
4.Since I'm migrating the old MySQL DB from an old Netware WEB server to the SLES, how can I change the default folder of the DB to other specific volume\partition?
