Oracle VM for SPARC (LDoms) Live Migration

This document provides information how we can increase application
availability by using the Oracle VM Server for SPARC software
(previously called Sun Logical Domains).

We tested the Oracle 11gr2 DB on a SPARC T4 while migration the
guest domain from one SPARC T4 server to another without shutting down the
Oracle DB.

In the testing the Swingbench OrderEntry workload was used to
generate workload, OrderEntry is based on the oe schema that ships
with Oracle 11g.

The scenario includes the following characteristic :
30GB DB disk size with 18GB SGA size, The number of
workload users were 50 and the time between actions taken by each
user were 100 ms.


The paper shows the complete configuration process, including the
creation and configuration of guest domains using the ldm command.
In addition to that Storage configuration and layout plus software requirements that
were used to demonstrate the Live Migration between two T4 systems.

Hi,
how can I migrate a guest ldom when source and target domains don't have access to the same subnet?

Thanks in advance for your comments.

Juan Vidal.

Hi Juan,

You need to have network connectivity between the the source and target control domains because you are moving the memory blocks across the network.

Thanks,
Orgad
