This subsection provides an overview of the processing performed by HA Monitor and HA Monitor Kit when startup of a server (Oracle instance or Oracle listener) fails. 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.
The following figure provides an overview of the processing performed by HA Monitor and HA Monitor Kit when startup of an Oracle instance fails.
Figure 2-5 Overview of processing when startup of an Oracle instance fails
#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.
The following figure provides an overview of the processing performed by HA Monitor and HA Monitor Kit when startup of an Oracle instance times out.
Figure 2-6 Overview of processing when startup of an Oracle instance times out
#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: HA Monitor executes the server termination command. This occurs only if you specified use in the termcmd_at_abort operand of the HA Monitor environment settings.
#4: 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.
The following figure provides an overview of the processing performed by HA Monitor and HA Monitor Kit when startup of an Oracle listener fails.
Figure 2-7 Overview of processing when startup of an Oracle listener fails
#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.
The following figure provides an overview of the processing performed by HA Monitor and HA Monitor Kit when startup of an Oracle listener times out.
Figure 2-8 Overview of processing when startup of an Oracle listener times out
#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.
