Chapter 5. SAP R/3’s System Management
This chapter provides a brief overview of SAP R/3’s systems management and
Tivoli’s Module for SAP R/3.
5.1 The Computing Center Management System (CCMS)
The CCMS is the SAP R/3 system management solution. It is available as a
standard tool. Since in a client/server environment the different components are
spread over several hardware servers, it is important to have a systems
management tool.
CCMS comprises System Monitoring and Systems Management. As the system
management tools can be used from any SAP R/3 client, there is no need for a
central console. System administrator can view the current state of the R/3
environment and run every system management task from every front end.
SAP R/3 provides MIB-based SNMP interface through which all relevant
information related to tasks,events etc. is made public and hence products like
Tivoli Management software can use it to monitor an R/3 system. The core
components of the CCMS are tools for the following:
• System and performance management
• Database and archiving management
• Workload management
• Output management
• Security management
The CCMS is open to external system management tools like Tivoli Module for
R/3 by making use of the CCMS System Management APIs, which allow
integration of R/3 system administration with Tivoli.
5.1.1 What’s New in CCMS in SAP R/3 Release 4.0
There is a new monitoring architecture in Release 4 of R/3 under which each
resource inside or outside of R/3 can be instrumented with a
data supplier . A data
supplier is nothing but a program that collects information. If it detects an
abnormal condition, it triggers an alert, which can be handled automatically by
the system or by the administrator. Alerts can be filtered and dispatched
according to administrative role or problem area. The alert infrastructure can be
extended by using a programming interface. Multiple R/3 systems can be
monitored.
The SAP R/3 systems can be reconfigured on the fly without shutting down; for
example, from dialog-intensive operation during the day time, you may switch
over to background-intensive processing at night. CCMS also provides a tool to
track and check the startup and system profiles, called the profile maintenance
tool. CCMS also provides you graphical control tools to view logs, start or stop
servers, check users, etc. CCMS also provides tools to monitor system and
business statistics.
