Layout of R/3 Manager Snap-In
Use
The R/3 Manager snap-in for the MMC provides essential information for monitoring the R/3 System and offers functions to start, stop and restart the system. All the information and functions available for R/3 can be accessed in the same way as the functions of other tools incorporated in the MMC. Therefore, before you begin working with the R/3 snap-in, it is useful to gain a general overview of the MMC layout and standard methods of accessing information and functions.
The MMC presents information on two panes of a window. The pane on the left is the scope pane. It displays available information in a tree structure that can be expanded and compressed. The pane on the right is the result pane. It shows detailed information about any item selected in the scope pane.
Features
When the MMC has been started, you can display the R/3 Manager snap-in by expanding the Console Root. The snap-in consists of a root node, SAP R/3 System, under which various R/3 Systems are listed. Under each of these systems, you can display individual instances. Each of the listed instances allows you to navigate to sub-nodes that provide detailed information about the system. The sub-nodes Process List, Current State and Open Alerts are always displayed. The additional nodes, Syslog, Queue Statistic and WP Table, are only available in Expert user mode.
The system icons and the nodes for instances, processes and alerts are displayed in different colors, depending on their state. The colors mean the following:
Gray: Unknown state, only outdated values, system is offline
Green: Error-free
Yellow: Critical
Red: Error
The R/3 snap-in periodically updates Process List information at a set time interval. Only the most critical state is passed on from the Process List to the parent instance node above it. The nodes at the R/3 System level contain all the states of the instance nodes. For example, if two instances are green, one is red and three are gray, the system node displays all 3 colors and thus reflects the states of all the instances.
To access detailed information about your R/3 system, you have to fully expand one of the R/3 instances listed in the MMC scope pane and then select an available item, for example, Open Alerts. Once an item has been selected, the corresponding information is displayed on the result pane. Usually you can navigate from here to further levels of detail or other categories of system information. The following table summarizes the available options:
Selected Item |
Information Displayed |
Process List |
Displays the processes that have been started by the start service and their state. |
Current Status |
Displays detailed information on the current state of the system (analogous to transaction RZ20). It allows you to navigate to different categories of system information and levels of detail. |
Open Alerts |
Displays the most serious alerts in the system (analogous to transaction RZ20). |
Syslog |
Displays the system log, even if the R/3 system is not functioning properly or is offline (expert mode only). |
Queue Statistic |
Displays the state of the R/3 queues (expert mode only). |
WP Table |
Displays information on work processes (analogous to transaction SM50). The R/3 System has to be started, but does not have to be functioning properly as shared memory of the R/3 System is accessed (expert mode only). |
You can choose to display the information you require in different ways using the View option. For example, the options Large icons, Small icons or List allow you to change the size and format of the display. Note that for the nodes Alerts, Syslog, Queue Statistic, WP Table, only the option List makes sense and is therefore the automatic default setting.
You can update the information displayed at any time using the Refresh option that is available on the context menu.
