To configure the map file share (a shared image folder) to Spectrum™ Technology Platform you first need a shared map image directory. To create a map file share, see Creating a Map Image File Share on Unix/Linux or Creating a Map Image File Share on Windows.
Once a map image directory has been created, configure the map file share:
-
Modify the Mapping Service configuration by pointing to a shared image folder
and load balance server. In the ImageCache change the Directory parameter to a
common image directory, and change the AccessBaseURL parameter to the load
balancer machine image URL.
If you are using a virtual machine environment, remember this IP address, as you must set the load balancer VM to this IP address.
For Unix/Linus installations:
<ImageCache>
<Directory>/<spatial server root>/server/modules/spatial/images</Directory>
<AccessBaseURL>http://<loadbalance_IP_address>/rest/Spatial/MappingService/internal/imageCache</AccessBaseURL>
<FileExpire>30</FileExpire>
<ScanInterval>30</ScanInterval>
</ImageCache>
For Windows installations:
<ImageCache>
<Directory>\\server\Share\images</Directory>
<AccessBaseURL>http://<loadbalance_IP_address>/rest/Spatial/MappingService/internal/imageCache</AccessBaseURL>
<FileExpire>30</FileExpire>
<ScanInterval>30</ScanInterval>
</ImageCache>
-
For Unix/Linux installations, you must set up a symbolic link to enable map images to go to the shared file system.
Create an images subfolder in the mounted share folder, e.g., /mnt/<linux mount>/images
cd /<spatial server root>/server/modules/spatial
rm –Rf images
ln -s /mnt/<linux mount>/images ./images
