Expanding a scaled system

A scaled system can be expanded at any time by adding further sub-servers. The master server can manage a maximum of 64 sub-servers.

Procedure

  1. With CTK, a sub-server can be added to an existing system. To do so, change to the Server settings dialog in the master server client setup and open the Change operation mode dialog in the Operation mode section. Use the Add button in the Sub-server specification dialog to add more sub-servers. Then, set up the new sub-servers as follows.
  2. First, use the PPM runppmconfig system command to export the entire configuration (including the associated InitSystem_settings.properties file) of an existing sub-server.

    Example

    runppmconfig -user system -client sub1 –mode export -system <installation directory>\ppm\server\bin\work\data_ppm\custom\sub2\xml

  3. Then, copy the file created by runppmconfig (InitSystem_settings.properties) into the config directory of the newly created sub-server so that the exported configuration is applied.
  4. Now the new sub-server is initialized with the configuration files you exported (PPM system command runinitdb). This ensures that the new sub-server has the same configuration as the master server.
  5. Restart the master server.

The existing sub-servers do not need to be restarted. The file InitSystem_settings.properties copied in step 2 needs to be emptied after initialization of the newly added sub-server in its config directory. The file must be empty.
