Distributed UMS vs. UMS High Availability (HA)
If you want to install the UMS with multiple servers, IGEL recommends to use the Distributed UMS feature:
-
for new installations
-
for existing single-instance installations. For more details, see IGEL UMS Installation.
If you have an existing fully functional HA installation, you can leave everything as it is. Note, however, that no new features will be added for the UMS HA.
If you want to migrate, see How to Migrate a UMS High Availability Installation to a Distributed UMS.
Problem
The UMS HA is not starting correctly after an upgrade from UMS 6 to UMS 12.
Environment
-
UMS 12 HA Installation
-
Windows Server
Solution
Enable the TCP/IPv6 option in the network adapter settings of the Windows server. For more details on installation requirements, see HA: Installation Requirements .
