2.9. Limitations of the WebManager¶
Information displayed by the WebManager does not always reflect the latest status. To acquire the latest information, click the Reload icon on the toolbar or Reload in the Tool menu.
- If a server fails while the WebManager is acquiring information, the information acquisition fails, which may result in the failure to show some objects.Wait for the next automatic update, or click the Reload icon on the toolbar or Reload in the Tool menu to reacquire the latest information.
The EXPRESSCLUSTER logs cannot be collected from two or more WebManager instances simultaneously.
If you work on the WebManager when no connectivity is established, it may take a while to regain control.
While the mouse pointer is the hourglass which indicates that the OS is processing something, moving the cursor outside the browser may return to the arrow icon even if the process is still underway.
If a proxy server is used, configure the proxy server so that the port number of the WebManager can be relayed.
When a reverse proxy server is used, the WebManager does not run normally.
When updating EXPRESSCLUSTER X SingleServerSafe , close all running browsers. Clear the Java cache (not browser cache) and open browsers.
When updating Java, close all running browsers. Clear the Java cache (not browser cache) and open browsers
If the client PC to connect to WebManager uses Java(TM) Runtime Environment Version 8.0 Update 162 or later, and cannot be connected to the Internet, it may take time to start WebManager. This can be avoided by setting Execute Certificate Revocation Check to Not Check on Detailed Settings on the Java Control Panel. For details of how to set it, check the Java website.
Do not set the "Reload Interval" on the WebManager tab or less than 30 seconds. If you set it for less than 30 seconds, it may affect the performance of EXPRESSCLUSTER X SingleServerSafe.
