Chapter 16: OperationsOverviewOperations is a generic category that refers to the tasks that would be done by a computeroperations group. These are the tasks that the people in the “glass room” in a data centerwould be doing. If you do not have a data center, these tasks do not disappear; they must beassigned to the appropriate employees.This chapter is important because operations is a crucial part of system administration.While learning to manage operations, readers will learn how to perform: Batch jobs Background jobs Operation modes BackupsTransaction SM51 allows you to look at all the servers in your system (for example, the PRDdatabase server and all of its application servers). You do not have to log into each serverindividually.The ability to look at the servers is important because if: One of your dialog application servers is not up, the users who usually log on to thatapplication server will not have a server to log on to. The batch application server is down, batch jobs that are specified to run on that serverwill not run.16–2Release 4.6A/B
Chapter 16: OperationsBackground (Batch) Jobs1. In the Command field, enter transaction SM51 and choose Enter(or from the SAP standard menu, choose Tools → Administration → Monitor → System monitoring →SM51 - Servers).2. Review the list of instances underServer name.Verify that all your instances arelisted. If it is listed, it is up andrunning.2In the R/3 System, a batch job is referred to as a background job. This job runsindependently of a user being logged on.There are two kinds of background jobs: RegularThese are jobs that are run on a regular schedule. Ad hocThese are jobs that are run as needed or required.Background jobs are used for the following reasons: Users have the flexibility of scheduling jobs when they are out of the office. The program can be run without locking a user session. Jobs that run for a long time would time out if executed online.System Administration Made Easy16–3
