User’s Guide
Setting up the source database (online backup)
This section details some of the tasks you must perform on the source database to prepare to run Fathom Replication. Refer to this section if you are using an online backup of the source database to create the target database.
To enable online backups, you need to implement the deferred agent startup mode, which is described in the "Overview of implementation tasks for deferred agent startup" section.
Preliminary tasks
To set up the source database, you must first perform the following tasks:
For more information on how to perform these tasks see the Progress Database Administration Guide and Reference .
Creating a structure file
Once you have shut down your source database, you need to build a structure file (.st) with the following command:
The structure file that originates from the source will be moved to the target machine.
Enabling After Imaging
To use Fathom Replication, After Imaging (AI) must be enabled on your source database. If AI is already enabled on your machine, skip this section and go to the "Enable the source for Fathom Replication" section.
To enable AI on your source database:
- Add AI areas by entering the following command:
where
addai.st
is the name of your structure file. This structure file defines AI areas to be added to the database. You might need to build a structure file that contains the AI area specifications.- Turn on AI with the
RFUTIL
Utility. For more information on using theRFUTIL
utility, see the Progress Database Administration Guide and Reference .Enable the source for Fathom Replication
Fathom Replication requires that the source database be enabled before starting the database. To enable the source database, enter the following command:
Configure the Fathom Replication server for deferred agent startup
Online backups require a server that is configured for deferred agent startup. To do so, you must set
defer-agent-startup
property to a valid time-out value (in minutes) in the server property file. In the following example, the time-out is set for 4 hours:
For more information, see the "Fathom Replication properties files" section and the "Fathom Replication properties" section.
Restart the source database
If you need information about starting databases, see the Progress Database Administration Guide and Reference .
Perform an online backup
To perform an online backup, use the
-REPLTargetCreation
and the-online
options. For example:
If you need more information about database backups, see the Progress Database Administration Guide and Reference .
After you complete the tasks described in this section, go to the "Starting up the target database" section.
