Configuring Packages and Their Services
Editing the Configuration File
Chapter 6304
•Use the monitored_subnet parameter to specify a subnet that is to
be monitored for this package. If there are multiple subnets, repeat
the parameter as many times as needed, on a new line each time.
• If this is a Serviceguard Extension for Oracle RAC (SGeRAC)
installation, you can use the cluster_interconnect_subnet
parameter (see page 288).
• If your package will use relocatable IP addresses, enter the
ip_subnet and ip_address. addresses. ip_subnet must be a subnet
that is already specified in the cluster configuration.
• For each service the package will run, enter values for the following
parameters (see page 289):
— service_name (for example, a daemon or long-running process)
— service_cmd (for example, the command that starts the process)
— service_fail_fast_enabled and service_halt_timeout if
you need to change them from their defaults.
— service_restart if you want the package to restart the service
if it exits. (A value of unlimited can be useful if you want the
service to execute in a loop, rather than exit and halt the
package.)
• To configure the package to monitor a registered EMS resource,
enter values for the following parameters (see page 291):
— resource_name
— resource_polling_interval
— resource_up_value
— resource_start
See “Parameters for Configuring EMS Resources” on page 170 for
more information and an example.
• If the package needs to mount LVM volumes to filesystems, use the
vg parameters to specify the names of the volume groups to be
activated, select the appropriate vgchange_cmd, and use the fs_
options in the FILESYSTEMS portion of the configuration file to specify
the options for mounting and unmounting the filesystems. Do not use
the vxvm_dg or cvm_dg parameters for LVM volume groups. Enter
each volume group on a separate line, for example:
