For Oracle installations, ensures that a master and slave
pipeline are configured regardless of the default role. This
ensures that in the event of a role change, for example when a
manual switch has taken place, that the slave has the correct
configuration to operate as a master, and vice versa. This
option also ensures that the replication position can be updated
correctly after the switch operation.
When enabled, the supplied prefix is added to each command alias
that is generated for a given installation. This enables
multiple installations to co-exist and and be accessible through
a unique alias. For example, if the executable prefix is
an alias for the installation to trepctl will
be created as east_trepctl.
Alias information for executable prefix data is stored within
file for each installation.
