Availability of Super-Group Capabilities

Make sure that operators, system managers, and others who may need super-user or

super-group capabilities have access to them. While a super-group user ID (255,n) is not

needed under normal conditions, it may be required to solve certain problems. Having

access to a super-group password is often the fastest—and sometimes the only way—to

solve a problem. The Introduction to NonStop Operations Management describes a

procedure for taking advantage of super-group capabilities while maintaining

appropriate security.

Disaster-Recovery Planning

Disaster-recovery or contingency planning is essential especially in companies where

day-to-day business activity is tied to a computer system. Section 8, “Planning for

Disasters,” describes disaster prevention and recovery planning in detail.

Automated Recovery Procedures

Automating your recovery procedures ensures that they are carried out quickly,

efficiently, and consistently whenever problems occur. Section 6, “Automating

Operations and Recovery Procedures,” provides guidelines for automating recovery

procedures.
