Question:
How can I increase the number of sites seen in the 'Go to' drop down menu in UMP?
Answer:
Unified Infrastructure Management (CA UIM) 8.x uses Liferay Portal Enterprise Edition for its portal framework. Liferay by default limits the drop down list to 8 sites but can be configured to display a larger number. To do so you will need to modify the portal-ext.properties file and add a new configuration key.
Edit:
$NIM_ROOT\probes\service\wasp\webapps\ROOT\WEB-INF\classes\portal-ext.properties
Add:
my.sites.max.elements= xx
Where xx is the number of elements to display.
After making the configuration change deactivate and reactivate the wasp probe. When the probe comes backup you should now be able to see more than 8 sites in the drop down menu.
Additional Information:
When upgrading make sure to back up the portal-ext.properties file as it can be overwritten back to defaults.
