Test Tools

Apache JMeter was used to perform functional tests targeting WWSK instances running on the Ubuntu, CentOS and Windows platforms.

  • The JMeter test resources (*.jmx files) are in the /jmeter folder hierarchy
  • Shell and Python scripts for generating WMS test input .csv can be found in the /scripts/wms_requests/ folder

Install/Update/Removal

Install

WWSK is installed by simply unzipping a platform specific distribution to a folder on a target computer.

Linux Specific Notes
The wwsk.service service unit file uses a hard-coded path to /opt/maps/wwsk to locate the WWSK installation. Assuming /opt/maps/wwsk is a symbolic-link, it must be created/updated to reference the root folder of your WWSK installation. Run ./install.sh to install the wwsk.service.

Removal

WWSK is removed by simply deleting the folder in which it was installed. If a wwsk.service has been created (Linux), it should be stopped, disabled and removed.

Update

The recommended practice to update WWSK is to:

  1. Install a new version of WWSK alongside an older version,
  2. (Optionally) copy/move data and workspaces from the old version to the new version,
  3. Remove the old version.

Updating WWSK by unzipping a distribution into an existing WWSK instance has not been tested and is not recommended.
