SMMS
Data Description
The SMMS event is used in SAP to administrate the message server. Only one message server can run in each SAP system. It performs the following tasks in the SAP system:
Central communication channel between the individual application servers (instances) of the system
Load distribution of logons using SAP GUI and RFC with logon groups
Information point for the Web Dispatcher and the application servers (each application server of the system firsts logs on to the message server)
When an instance is started, the dispatcher process contacts the message server so that it can announce the services it provides (DIA, BTC, SPO, UPD, and so on). If the connection setup to the message server fails, an entry is made in the system log (syslog).
If the message server stops working, it must be restarted as quickly as possible to ensure that the system continues to operate smoothly.
Potential Use Cases
This event could be used in the following scenarios:
Alert on failures associated with the message server.
Determine the protocol types used by the message server.
Correlate the information regarding the message server with other SAP processes such as work processes or data from ST03.
