How You Prepare RAMDB Before Linking

You can use the following methods to prepare RAMDB before you link your regions to set up the multisystem environment:

Important! When you link two regions, one region has the database you want and the other region will have its database overwritten. Linking must always be initiated from the region whose database is to be overwritten.

• You can create the system images for the individual systems on which the regions are deployed. You then assign one region as focal, transmit the images from the other regions to it, and then link the other region to it.

  The linking must be done from the new region where the database is deleted and rebuilt to mirror that in the focal region.

• You can create the system images for all the required systems in the complex in the main focal region. Then each new region can be deployed with the default RAMDB provided during setup. The default RAMDB is deleted and rebuilt with the required system images when the region is linked to the focal region.

After the regions are linked, their RAMDBs are kept synchronized automatically.

Note: For more information about how to set up a multisystem environment, see the Administration Guide.
