Chapter 1 Introduction to Administration : Engine Startup and Shutdown Sequence

Engine Startup and Shutdown Sequence
This section outlines the main actions that occur during engine startup and shutdown (in normal circumstances). In any particular project only some of the actions may be required. For example, a project may have no startup rule functions.
TIBCO BusinessEvents Express  Content relating to Cache OM and backing store does not apply to TIBCO BusinessEvents Express edition.
Except where noted, this section assumes cache OM and inference agent startup and shutdown. It provides the main milestones only.
Cluster Startup and Shutdown
There are only two main points to keep in mind for orderly system startup and shutdown:
Start storage-enabled agents (cache agents) first   When Cache OM is used, you must start a node that has storage enabled first. In production systems that would be a dedicated cache agent engine. (In test deployments this could be another type of agent node with cache storage enabled.)
Stop other engines before storage-enabled agents (cache agents)  In unusual situations where all cache agents are stopped but engines running other types of agents are running, you must restart all engines.
Startup Sequence
During engine startup the following actions occur:
1.
2.
3.
(Cache OM only) Inactive (Standby) Nodes  If all agents in an engine are inactive, then this ends the startup sequence for that engine.
4.
5.
6.
7.
8.
9.
10.
Shutdown Sequence
During engine shutdown the following main actions occur:
1.
2.
3.
