Issue/Introduction
On our Management UI, we have a Router DSA that is routing requests to a number of Data DSAs that are grouped into diffferent sets of load-share groups. Do we need to name each of these groups using different names? The "Load Share Group" is on the "Ext Knowledge" tab of a DSA configuration screen.
Environment
Release: 14.1
Component: CA Directory
Resolution
The "Load Share Group" is used to name a group of load share partners when there is a need to distinguish groups that share the same DSA prefix but may have different precedences.
For example group1 could be in data center 1 while group2 in data center2. In this scenario, ldap clients that connect to DSAs in the data center 1 tends to have the preference to use use DSAs in the data center 1 so that the traffic does not need to go through the network link between data center 1 and data center 2 as the link is presumable slower than just the connection to servers in the data center 1. With the use case, DSAs in the data center 1 can use the "set precedence Command" to set their precedence-list so that group1 comes betfore group2:
For Management UI, the command is set using the Precedence field on the "Settings" tab.
This also means if there is no need to name the group of load-share group, there is no need to use the set-precedence command and the field on the Management UI can simply be left blank.
