We have middleware platform enabling services, including the following services: Weblogic, WebTierSOA Suite, Service Bus (OSB), Oracle iAs, WebCenter, Data INtegrator (ODI), Identity Management, Goldengate and any Oracle technology product that is installed over Weblogic.
Technological upgrading projects have a series of benefits not obvious to the majority of organizations:
Minimizing operational risk
Premium support
New characteristics, improving availabilty.
Security patches
Avoiding an emergency migration in case of an existing failure
Better investment use.
Adding new characteristics (performance, administration, functionals).
Automatic improvements (without app changes).
Allowing HW and SO updates (flexibility)
Diminishing TSO thanks to new administration options.
High availabilty and disaster recoveries, don´t appear to be as relevant in Middleware components as in Databases, it´s implementation requires careful planning in the following aspects:
Administration servers.
Cluster configuration.
Configuration repositories .
Session information.
JMS tail storage.
