Copying files to use on the backup master domain manager
To back up the important master domain manager files
to the backup master domain manager,
use the following procedure:
- Copy the Security file on the master domain manager to the <TWA_home>/TWS directory on the backup master domain manager. Add a suffix to the file so that it does not overwrite the backup master domain manager's own Security file, for example, Security_from_MDM.
- Copy all files in the TWA_home/TWS/mozart directory.
- Copy the localopts file (see Setting local options for the location). Add a suffix to the file so that it does not overwrite the backup master domain manager's own localopts file; for example, localopts_from_MDM.
This procedure must be performed each production period, or whenever there are significant changes to any objects. It can be incorporated into a script.
In addition to these required files, you might also want to copy
the following:
- Any scripts you might have written.
- Archived Symphony files, for reference.
- Log files, for reference.
Note: Another approach could be to place all of the above files
on a separately mountable file system, that could easily be unmounted
from the master domain manager and
mounted on the backup master domain manager in
the event of need. You would almost certainly want to backup these
files in addition, to protect against loss of the separately mountable
file system.
To prevent the loss of messages caused by a master domain manager error, you can use the fault-tolerant switch-manager facility.
