7 Event Management
The TCP/IP subsystem reports information about events it detects by issuing event
messages. A management application can obtain these event messages by opening
an Event Management Service (EMS) distributor process and requesting the
messages. The application can also specify that a filter be applied to select certain
event messages. This section describes the event messages that the TCP/IP
subsystem can issue and the specific programming considerations for dealing with
these event messages in an application. For general information on how an application
obtains event messages from a subsystem, see the EMS Manual.
In this section, event-message tokens and their values are represented in data
definition language (DDL). For a brief explanation of DDL as it applies to SPI, see the
SPI Programming Manual.
Subsystem Processes That Report Events
Event messages are generated by the TCP/IP process. All event messages issued by
the TCP/IP subsystem contain the subsystem ID, ZTCI-VAL-SSID, which is described
in SPI Standard Definitions on page 5-1. For more information about subsystem IDs,
see the SPI Programming Manual.
Table 7-1 lists the event messages that the TCP/IP subsystem can issue.
