Change the number of core group coordinators
Overview
For large cells, multiple core group coordinators are recommended. In general, one coordinator per 20 core group members.
Change the number of core group coordinators only if:
- IBM support instructs you to do so.
- we are directed to do so as part of the installation process for another WebSphere product.
- The coordinator process is consuming abnormally high amounts of memory or CPU resources.
- we are scaling up the number of servers in a cell.
To change the number of core group coordinators for a core group, go to...
Servers | Core Groups | Core group settings | core_group...and specify the number of coordinators for this core group in the field...
