A process called dbm irror has to be executed in the same machine where the original server is runnin g. dbmirror is a secondary server, i.e., a server that runs in an inferior level as that of Essentia. dbmirror will be the process who will update the mirror da tabase using the journal and a command called dbmcopy, which is similar to the U NIX cp command, but allowing incremental copies.
To get a firmer grap on these concepts, let's see a sample session to install an Essentia server with its corresponding mirror.
Sample Diagram:
Also, install the server ``msisint'' in host B, assuring that it has exactly the same structure and data.
Be sure that the file /etc/ess.env is properly configured for an Essentia remote server (see ``Installation''). Turn off the Mirroring parameter in msisint.sv (i.e., assing it a zero value).
Once the servers are properly ``sincronized'', perform the following operations:
#essentia sisint
#essentia -m msisint
To temporarily suspend the mirroring process, use the command
