refresh Command

Edit online

Purpose

Requests a refresh of a subsystem or group of subsystems.

Syntax

refresh [ -h Host] { -g Group| -p SubsystemPID| -s Subsystem}

Description

The refresh command sends the System Resource Controller a subsystem refresh request that is forwarded to the subsystem. The refresh action is subsystem-dependent.

Note: The refresh command is unsuccessful if the communication method for the subsystems is signals.

Flags

Item Description
-g Group Specifies a group of subsystems to refresh. The refresh command is unsuccessful if the Group name is not contained in the subsystem object class.
-h Host Specifies the foreign Host machine on which this refresh action is requested. The local user must be running as "root". The remote system must be configured to accept remote System Resource Controller requests. That is, the srcmstr daemon (see /etc/inittab) must be started with the -r flag and the /etc/hosts.equiv or .rhosts file must be configured to allow remote requests.
-p SubsystemPID Specifies a particular instance of the subsystem to refresh.
-s Subsystem Specifies a subsystem to refresh. The Subsystem name can be the actual subsystem name or the synonym name for the subsystem. The refresh command is unsuccessful if Subsystem name is not contained in the subsystem object class.
