2.2.1 Flow of processing for starting a server

This subsection provides an overview of the processing performed by HA Monitor and HA Monitor Kit when a server (Oracle instance or Oracle listener) is started. Note that the figures used in this subsection show examples in which an Oracle instance or an Oracle listener is associated with a single server.

Organization of this subsection
(1) Flow of processing for starting an Oracle instance
(2) Flow of processing for starting an Oracle listener

(1) Flow of processing for starting an Oracle instance

The following figure provides an overview of the processing performed by HA Monitor and HA Monitor Kit when an Oracle instance is started.

#1: Executed to allow an IP address for client connection to be included in the server resources. For details about the resources required by servers, see 3.1.2 Resource configuration considerations and 3.2.6 Setting up the shared resources to be used by Oracle.

#2: HA Monitor executes the server start command.

#3: When a single server is used to control multiple Oracle instances, the flow of processing described in this subsection is repeated as many times as there are Oracle instances.

(2) Flow of processing for starting an Oracle listener

The following figure provides an overview of the processing performed by HA Monitor and HA Monitor Kit when an Oracle listener is started.
