29.3 Using the sec_admin Program

While the DCE control program includes commands that create and maintain the master

and slave replicas of the registry, the program does not provide functions that are useful

for reconﬁguring the replica set in a cell. Reconﬁguring the registry replica set in a cell

involves reassigning the roles of the master and the slaves. This reassignment of roles

typically accompanies a change in the operations on one or more of the nodes in the cell.

It becomes desirable for some reason to change the site of the master replica, and the

easiest way to move the master is to swap its role with a slave. The sec_admin program

commands that you use to exchange master and slave replica roles are the become

command and change_master command. The following subsections provide

instructions for starting, stopping, and getting help on the registry editor, and provide

brief descriptions of the become and change_master commands.

29.3.1 Starting, Stopping, and Getting Help

To start the sec_admin program, enter the following command:

$ dceshared/bin/sec_admin

Once invoked, sec_admin enters the interactive mode in which you can execute

commands.

To exit from sec_admin, enter the following command:

sec_admin> quit

To display a list of the sec_admin commands, enter the following command:

sec_admin> help

29.3.2 sec_admin Commands for Reconﬁguring Replica Sets

Table 29-3 provides brief descriptions of the sec_admin commands for reconﬁguring the

registry’s replica set. Instructions for changing master and slave replica roles can be

found in Chapter 40 of this guide.
