PQ54963: PERFORMANCE PROBLEM IN THE ADMIN CONSOLE IN A MULTI-NODE ENVIRONMENT, WHEN ONE OF THE NODES GOES DOWN.


APAR

APAR status
Closed as program error.

Error description
When running in a multi-node environment and one of the nodes
goes down, the admin console continues to attempt to contact
the down'ed node for various user operations.  This results
in performance problems because the user must wait for the
connection timeout in order for the operation to complete.
Local fix

* PROBLEM DESCRIPTION: When in a multi-node environment and    *
*                      one node goes down, performance of      *
*                      admin console is very slow.             *
****************************************************************
* RECOMMENDATION:                                              *
****************************************************************
Performance was degraded because admin console was continuing
to attempt to contact downed node to obtain active attributes
during various operations.
Problem conclusion
Admin server was modified to mark a node "down" and prevent
future attempts to contact the node via the admin console
after detecting node down 1st time.  Node remains down until
manually reconnected using admin console, thus minimizing
performance impacts.
Temporary fix
