<h1 align=center>Replication environment priorities</h1>
<p>Each database environment included in a replication group must have a
priority, which specifies a relative ordering among the different
environments in a replication group. This ordering determines which
environment will be selected as a new master in case the existing master
fails.
<p>Priorities must be a non-negative integer, but do not need to be unique
throughout the replication group. A priority of 0 means the system can
never become a master, regardless. Otherwise, larger valued priorities
indicate a more desirable master. For example, if a replication group
consists of three database environments, two of which are connected by
an OC3 and the third of which is connected by a T1, the third database
environment should be assigned a priority value which is lower than
either of the other two.
