2.3.1 Event service

An event service is functionality that registers and manages an event that occurs in the system as a JP1 event.

The JP1/Base event service can be used for the following:

Storing JP1 events in the event database

When JP1/Base receives JP1 events, it stores them in a file called the event database. Each host with JP1/Base has its own event database.
Forwarding JP1 events to other hosts

The JP1 events generated at each host can be forwarded to a management server at a higher level in the hierarchy. You can choose which JP1 events you want to forward to higher-level management servers. Forwarding events helps the management server monitor the status of each host and promptly detect any problems that might exist, dealing with them immediately.

JP1/Base can also automatically re-forward JP1 events that were not sent the first time due to a transmission error caused by a network error or by the event server not running.
Maintaining partial upward compatibility with the event services provided by the pre-Version 6 programs, JP1/SES and JP1/AJS

Events issued by JP1/SES (a program in version 5 and earlier) running under UNIX, and events issued via commands executed in JP1/AJS (another program in version 5 and earlier) running under Windows NT, can also be acquired.

A program called the event server manages the above features. When the event server is active, JP1 events can be sent and received.
