Default Re: make a slave db a master db

Hi Keith,
Thanks for the info,
Actually, we are moving our db to a new database center, so during one point
of time, we will not have access to the old data center (master db), so i
want to set up a second slave, and at a specific point in time, make the
second slave, a stand alone master db.

regards
anandkl
