Chapter 1: R/3 System Administration BasicsR/3 System GuidelinesEverything you do as a system administrator should be focused on protecting andmaintaining the system’s integrity. If the system’s integrity is compromised, incorrect decisions could be made based oninvalid data. If the system cannot be recovered after a disaster, your company could be out ofbusiness. The system administrator must have a positive, professional attitude.If the system administrator has less than this attitude, critical tasks may not be properlycompleted (for example, backups may not be taken as scheduled and backup logs maynot be checked, which reduces the chances for a successful recovery). System administrators should maintain a “my job is on the line” attitude.This attitude helps to ensure that administrators focus on maintaining the integrity ofthe system. The company may not survive if the system crashes and cannot berecovered. The system must be protected from internal and external sources.One problem today is employees “poking around” in the network. R/3 is so large and complex that one person cannot be expected to know everything.If you are unsure which task to complete or how to complete it, you could make amistake and cause a larger problem. Mistakes within the system can be expensive.Certain things cannot be “undone,” and once set, are set forever. The only way to learn is to ask.There are no dumb questions—only dumb reasons for not asking them.
