Installing the Distributed IGEL UMS

This article describes how to install the Distributed IGEL Universal Management Suite (UMS). Detailed information on the Distributed UMS can be found under Installing an IGEL UMS Server. The following instructions can be used:

• if you plan a new installation of the Distributed UMS
• if you already have a standard UMS installation but want to switch to the Distributed UMS
  
  

To install the Distributed UMS, proceed as follows:

1. Install the first UMS Server. For the instructions, see IGEL UMS Installation under Windows or IGEL UMS Installation under Linux. 
   In the UMS installer, select Standard UMS with either an embedded or external database.
   
   
   
2. Configure an external database, see Connecting External Database Systems.
   
   
3. Add this database as a data source in the UMS Administrator > Datasource and activate it. See How to Set Up a Data Source in the IGEL UMS Administrator.
   If you already have a standard UMS installation with an embedded database and want to switch to the Distributed UMS, copy the embedded database to the new external data source. See Copying a Data Source. 
   
   
4. Open the UMS Console and go under UMS Administration > UMS Network > Server to check that the server is up and running.
   
   

5. In the UMS Console, go to UMS Administration > Global Configuration > Server Network Settings and activate Distributed UMS enabled. 
   
   
   

6. Restart the UMS Server service, e.g. via UMS Administrator > Distributed UMS. For detailed instructions on how you can restart services, see IGEL UMS HA Services and Processes.
   
   
   

7. Install other UMS Servers and connect them to the same database.

   

   For load distribution, DNS-Round-Robin load balancing of the server IP address should be used. The DNS-Round-Robin for igelrmserver should point to all servers.

If you activated the Distributed UMS feature and have multiple UMS Servers, take care in case you decide to disable the feature. If the Distributed UMS feature is deactivated but more than one UMS Server is using the same database, no synchronization will be done between the UMS Servers.
