SCR Overview
Additional Uses of SCR
Change Management
SCR can complement your system change management process by
keeping good records of changes and alerting you to unplanned
changes.
• You can configure SCR to automatically take periodic snapshots.
• You can take snapshots whenever you want them.
• You can tailor reports to compare the current system state to
previous states.
• You can generate records of all reports.
Use the scrupdate, scrconfig, and scrhist commands to perform
change management, as follows:
1. Complete the initial configuration steps described in this chapter.
2. Take an initial snapshot of the systems as they are, to provide a base
for detecting future changes:
# scrupdate -a
3. Set SCR to collect data weekly or as often as you wish:
# scrconfig -i lw
4. Have SCR email a system history report to you. (Remember that
SCR will not store a snapshot if the node has not changed since the
last snapshot.)
# scrhist
5. When you receive the email, order a scrdiff report on the system
nodes that showed differences, to see what they are.
# scrdiff
