When you execute the hdestart command at the source system, the source Datareplicator starts in accordance with the extraction system definition, extraction environment definition, and transmission environment definition. In the Windows edition of Datareplicator, execute the command at the command prompt.

To initialize the source Datareplicator's environment, execute the hdestart -i command. To initialize the transmission environment only for a specific target, use the hdestart -i -S command to initialize the environment only for the corresponding target.

If you use HiRDB's standby-less system switchover (effects distributed) facility, you can also use the hdestart_n command to execute partial start (to start extraction master processes and extraction node master processes separately).

For details, see the hdestart command in Chapter 7. Command Syntax.

In the Windows edition of Datareplicator, you can also use either of the following methods to start the source Datareplicator:

• Start the extraction service manually.
• Set the extraction service to start automatically when Windows starts.

To set the extraction service to start automatically when Windows starts:

1. In Control Panel, double-click the Services icon.
2. Verify that the node master process startup service is started.
3. Under Service, choose HiRDB Datareplicator (Source Site).
4. In the Startup Parameters field, specify the startup options (options for the hdestart command).
5. Click the Start button.

Notes on initial startup by specifying the -i option

• When you execute initial start from the service, Datareplicator does not display a message asking whether files are to be initialized. Therefore, before you execute an initial start, check that HiRDB Datareplicator linkage is not underway at the source HiRDB.
• Because the source Datareplicator terminates once file initialization is completed, an error message might appear in the Service dialog box. In such a case, check the event viewer or error log file for the initialization completion message. If an initialization completion message has been issued, initial start executed normally.

Setting the extraction service to start automatically when Windows starts

The following explains the procedure for setting the extraction service to start automatically when Windows starts. In this case, you cannot specify any start options (options in the hdestart command).

To set the extraction service to start automatically when Windows starts:

1. In Control Panel, double-click the Services icon.
2. Verify that the node master process startup service is set to start automatically.
3. Under Service, choose HiRDB Datareplicator (Source Site).
4. Click the Startup button.
5. In the Service dialog box, under Startup Type, choose Automatic.
6. Click the OK button.
7. Click the Close button.

The next time you start Windows, the extraction service will start automatically.

There are four start modes for the source Datareplicator, as described below.

For details about the start modes, see the hdestart command in Chapter 7. Command Syntax.

Initial start

The initial start mode only initializes the following files; it does not actually start the source Datareplicator:

• Extraction information queue files
• Extraction master status file
• Extraction server status file
• Extraction master error information files
• Extraction node master error information files
• Extraction master trace files
• Extraction node master trace files
• Data linkage file

Partial initial start

The partial initial start mode initializes the transmission environments for specified destinations only, in accordance with the extraction system definition or the transmission environment definitions for the specified destinations (partial initialization). It does not change the transmission environments for any other destinations. This mode does not actually start the source Datareplicator.

Normal start

The normal start mode starts the source Datareplicator in accordance with the extraction system definition, extraction environment definition, and transmission environment definitions without inheriting the settings of the previous session.

Restart

When extraction or transmission processing in the previous session terminated with an error, the restart start mode starts the source Datareplicator with the same settings that were in effect for the previous session in order to guarantee conformity between source and target databases.
