Development Life Cycle Topology
1-10 Advanced Topologies for Enterprise Deployments
1.6.1 Moving Applications from Test to Stage
To move applications from a test to a stage environment, you deploy them on middle
tiers in the stage environment. The applications use the Identity Management and
Oracle Application Server Metadata Repository of the stage environment.
If an application uses custom data in a database, you need to move that data from that
database to a database in the stage environment.
1.6.2 Moving Applications from Stage to Production
You can move applications from a stage environment to a production by deploying the
applications and moving any application-specific data from the stage environment to
the production environment.
Another method is to use the rejoin feature, which enables you to unjoin a middle tier
from its infrastructure and associate it with a different infrastructure. You can use this
feature to move middle tiers (and their applications) from stage to production.
You still need to move application-specific data stored in a stage database to a
database in the production environment.
Rejoining middle tiers is convenient if you need additional computers and application
server resources for the production environment. In one step, you can add a computer
that already has a middle tier and deployed applications.
See the Oracle Application Server 10g Administrator’s Guide for details on rejoining
middle tiers.
