Linux PaceMaker Equivalent to a SharedAddress Resource Type
In HA platforms, there is the concept of a "Scalable Resource Type, which included the sharedaddress" that is used in commonly Web Servers resource groups. The sharedaddress resource type is provided so a developer can use this Resource type to build their own scalable resource group. I see PaceMaker provides a Apache Resource type, but I do not believe its generic to create your own group to use the sharedAddress ability with. Red Hat support seems to be confounded by the concept, it also could be I am not explaining it correctly. Most anyone who has any type of HA Application background should be able to understand the concept I am talking about.
Does PaceMaker provide a sharedAddress or similiar concept, resource type to roll your own Scalable Resource Group?

Hi all...
In my Unix system a program exists called "daemon2" which is responsible to enqueue program executions. For example, if I want to make the system to enqueue lpr executions for certain users, I call daemon2 with lpr as the parameter.
Is there an equivalent in Linux?
Thanks

poe::resource
POE::Resource(3pm) User Contributed Perl Documentation POE::Resource(3pm)
NAME
POE::Resource - internal resource managers for POE::Kernel
SYNOPSIS
Varies, although most POE::Resource subclasses do not have public APIs.
DESCRIPTION
POE manages several types of information internally. Its Resource classes are mix-ins designed to manage those types of information behind
tidy, mostly private interfaces. This was done to facilitate testing and a conversion to C without the need to port POE::Kernel all at
once.
POE::Resource subclasses are generally different from one another, but there are some similarities to note.
Every resource should have an initializer and finalizer method. Initializers set up initial data and link resources into POE::Kernel.
Finalizers clean up any remaining data and verify that each resource subsystem was left in a consistent state.
One common theme in resource implementations is that they don't need to perform much error checking, if any. Resource methods are used
internally by POE::Kernel and/or POE::API classes, so it's up to them to ensure correct usage.
Resource methods follow the naming convention _data_???_activity, where ??? is an abbreviation for the type of resource it belongs to:
POE::Resource::Events _data_ev_initialize
POE::Resource::FileHandles _data_handle_initialize
POE::Resource::Signals _data_sig_initialize
Finalizer methods end in "_finalize".
_data_ev_finalize
_data_handle_finalize
_data_sig_finalize
Finalizers return true if a resource shut down cleanly, or false if there were inconsistencies or leaks during end-of-run checking. The
t/res/*.t tests rely on these return values.
