Using the immediate agent startup mode

Following is an overview of the tasks you must perform to use the immediate agent startup mode for OpenEdge Replication. To use startup mode, be sure that the server and agent are already in synchronous communication.

To set up the immediate agent startup mode for OpenEdge Replication:

1. Using the PROENV utility, ensure that you have the $DLC, $PROMSGS, $DSRHOME, and $PROCFG environment variables set correctly. For more information about these variables, see OpenEdge Getting Started: Installation and Configuration.

2. Shut down the database you intend to use as the source.

3. On the source machine, do the following:

a. Create an initial backup of the source database.

b. Create a structure file (.st) of the source database.

c. Ensure that after-imaging is set up and running.

d. Enable the source database for OpenEdge Replication.

e. Perform an incremental backup of the source database.

For more information about these tasks, see Setting up the OpenEdge Replication databases.

4. On the target machine, do the following:

a. Copy the source database backup to the target machine. (The source database backup is the initial copy of the target database.)

b. Enable the target database for OpenEdge Replication.

For more information about these tasks, see Setting up the OpenEdge Replication target database.

5. To set OpenEdge Replication property values, do the following:

a. Configure the server properties file.

b. Configure the agent properties file.

For more information, see Configuring the OpenEdge Replication property files.

6. Start the databases in the following order:

a. The target database

b. The source database

Because the databases are enabled for OpenEdge Replication, the OpenEdge Replication server and agents will also start.

This immediate agent startup mode does not allow source or target database activity until both the server and agents complete their startup and initialization phases.
