Initializing Cluster Attributes in the Configuration File

You may assign values for cluster attributes while configuring the cluster. (See Cluster Attributes for a description of each attribute cited below.)

Review the following sample configuration:

cluster vcs-india (
  EngineClass = "RT"
  EnginePriority = "20"
  ProcessClass = "TS"
  ProcessPriority = "40"
)

Setting Cluster Attributes from the Command Line

To update the EngineClass

# haclus -modify EngineClass value

For example, to set the EngineClass attribute to RealTime::

# haclus -modify EngineClass "RT"

To update the EnginePriority

# haclus -modify EnginePriority value

For example, to set the EnginePriority to 20::

# haclus -modify EnginePriority "20"

To update the ProcessClass

# haclus -modify ProcessClass value

For example, to set the ProcessClass to TimeSharing:

# haclus -modify ProcessClass "TS"

To update the ProcessPriority

# haclus -modify ProcessPriority value

For example, to set the ProcessPriority to 40:

# haclus -modify ProcessPriority "40"

Note For the attributes EngineClass and EnginePriority, changes are effective immediately. For ProcessClass and ProcessPriority changes become effective only for processes fired after the execution of the haclus command.
