Error description
DWLM Controller is prematurely setting the weight to 0 for servers that are in 'inprogress' maintenance mode causing disruption of service when a node or an other middleware server is put into maintenance mode.
Local fix
Problem summary
**************************************************************** * USERS AFFECTED: WebSphere Virtual Enterprise 'Other * * middleware server' dynamic clusters (DCs) * * users * **************************************************************** * PROBLEM DESCRIPTION: The DWLM controller prematurely sets * * the weight to 0 for 'other middleware * * servers' in 'inprogress' maintenance * * mode. * **************************************************************** * RECOMMENDATION: * **************************************************************** The dynamic workload management (DWLM) controller does not recognize the'inprogress' maintenance mode state for members of 'other middleware server' dynamic clusters. Therefore the DWLM controller sets the weight to 0 for servers that are not yet completely in maintanenance mode. This behaviour causes service disruption because the application placement controller does not start a replacement server.
Problem conclusion
The issue is now resolved: the dynamic workload management (DWLM) controller recognizes the 'inprogress' maintenance mode state, and sets the member weight to 0 only after the servers are in maintenance mode. This fix will be included in the next WebSphere Virtual Enterprise fix pack.
