This article describes the basics of how to configure a swSlaveServer.
- Existing swServer (master server) is configured and running
- swSlaveServer hardware meets the requirements in SystemWeaver Server - Software and Hardware Requirements
- swSlaveServer installation (see below) is in place on the hardware that will host the swSlaveServer
The following directory should be located on the slave server machine:
If your organization is considering a slave server for the first time, please contact email@example.com to obtain the necessary installation files.
Configuring the Slave Server
- Open the swSlaveServer.ini in a text editor.
- Configure the settings (see table below).
- Save your changes.
swSlaveServer.ini Configuration Options
|SWServerIP||The domain address of the SystemWeaver master server (swServer.exe) that the Slave Server should connect to. The address may be specified as either a fixed numerical address (123.456.789.012) or a domain name (EV198).|
|SWServerPort||The port number of the SystemWeaver master server that the Slave Server should connect to.|
|Port||The same entry as the .props files*|
|IP||The same entry as the .props files.*|
|CertPassword||The same entry as the .props files.*|
|AutoStart||The same entry as the .props files.*|
|LoadAllData||Defines if the slave server should load the complete database from the main server upon startup (true) or not (false).|
|SWUser||Should be set to "system".|
|SWPassword||Should be set to the password of the "system" user.|
|SWPasswordEncrypted||An alternative to the SWPassword entry, where the password is entered in encrypted form. The SystemWeaver utility tool EncryptString.exe may be used for generating an encrypted password for this purpose. Contact firstname.lastname@example.org to obtain the tool if desired.|
|SimulateLatency||Simulates a network latency between the slave and main server. The integer value is set in ms.|
Note that this option should never be used in production environments.
|WriteChannelCount||Set to the number of write channels to be used.|
"0" implies 1 channel for all (Read and Write) operations,
"1" implies 1 channel for Read operations and 1 channel for Write operations,
"2-N" implies 1 channel for Read operations and multiple (N) channels for Write operations.
* See "Format of props file" in the SystemWeaver Help.
Starting the Test Slave Server
The swTestSlaveServer.exe provides a user-friendly interface and log window. It will basically read the contents of the swSlaveServer.ini and present those settings in the interface.
Before starting the swTestSlaveServer.exe, be sure that the swSlaveServer.ini is located in the same directory as the application.
- Test the Slave Server first by opening the swTestSlaveServer application. The configuration entries made will be viewable in the GUI.
- Click Start. When start-up is completed, it will be indicated in the log window:
Starting the Slave Server
Before starting the swSlaveServer.exe, be sure that the swSlaveServer.ini is located in the same directory as the application.
- To start the slave server, double-click on the swSlaveServer.exe. A swSlaveServer window will display when it is up and running:
Note: Depending on the selected settings, there may be a delay. For example, if LoadAllData is set to 'true', the slave server must first load all server data from the master server as part of its start-up process. You will see it loading the tables in the log and when it is completed, it will indicate "All data loaded."
Using the swServerMonitorService
A third alternative is to use the swMonitorService.exe to start/restart the slave server. The swServerMonitorService application supports multiple instances of the same SystemWeaver server as a service on the same server computer. Learn more about this option in the Help by searching for 'swServerMonitorService'.
