Process migration
Using binary translators, would it be possible capture the runtime image (instructions and data) of processes and translate these so that the process can run from where it left on a machine with a different architecture? This will be useful for migrating applications to heterogenous systems for purposes of high availability.

NAME
cm - cluster monitor for high availability clusters
Remarks
Cluster operations require the installation of the optional Serviceguard or Serviceguard Extension for RAC software, which is not included
in the standard HP-UX operating system.
DESCRIPTION
Serviceguard and Serviceguard Extension for RAC are high availability products which provide an environment such that after a failure of a
node, services (applications) can be up and running again on another node within a very short amount of time. In addition, Serviceguard
Extension for RAC is the enabling software for the Real Application Clusters (RAC). Working with the basic Serviceguard product, Service-
guard Extension for Faster Failover allows configuration of clusters for optimized failover.
Commands
The following set of commands is used to configure a high availability cluster:
cmquerycl(1M)
cmmakepkg(1M)
cmcheckconf(1M)
cmapplyconf(1M)
The following commands are used to run or halt a cluster:
cmruncl(1M)
cmhaltcl(1M)
cmrunnode(1M)
cmhaltnode(1M)
cmviewcl(1M)
Once a cluster is formed, the following commands are provided for manual operation on high availability packages:
cmrunpkg(1M)
cmhaltpkg(1M)
cmmodpkg(1M)
The following commands are used within a package control script to control the services and networks configured for a package:
cmrunserv(1M)
cmhaltserv(1M)
cmmodnet(1M)
A command is provided to aid in migrating from a SwitchOver/UX configuration to a Serviceguard cluster:
cmmigrate(1M)
This command is not applicable with Serviceguard Extension for RAC.
