Deployment in PROD Env

In production env the deployments are usually script or autosys based .

This is to eliminate error while deployment and make the deployment faster

if the deployment is done graphically then then procedure is the same as in other env.

ie Install Application >> browse the ear >> next .. next .. next .. finish :-) ( obviously you need to select the appropriate mapping , virual host etc )

As a procedure per say its normally done this way

1) Take the backup of the old ear in both PROD and DR
2) Confirm with the AD wherether the ear staged is the latest one.
3) Network team flips the DNS to point to the DR
4) Do the deployment in DR
5) Check the logs and access the DR apps , test the application using the DR url
6) If the apps is working fine and its confirmed by the AD team then
7) Network Team to flip the PROD
8) Do the deployment in PROD
9) Check the logs and access the PROD apps , test the application using the PROD url

where  AD = Application Development
DR = Disaster Recovery
