APAR status
Closed as new function.
Error description
The Load Balancer high availability state is controlled in the executor code. The dsserver process queries the status based off the highavailability interval setting that is defined in seconds. The interval should allow for milliseconds to maintain accurate status.
Local fix
Problem summary
**************************************************************** * USERS AFFECTED: IBM WebSphere Load Balancer users with * * LB high availability configured * **************************************************************** * PROBLEM DESCRIPTION: The Load Balancer server does not * * obtain the high availability status * * in a timely fashion. * **************************************************************** * RECOMMENDATION: * **************************************************************** The Load Balancer server obtains the current high availability status from Load Balancer's executor code every 3 seconds. High availability heartbeats occur every 0.5 seconds and the high availability status can change every 0.5 second. The server needs to query the status more frequently to provide accurate status.
Problem conclusion
The interval to query the high availability status was modified to use milliseconds instead of seconds. Status queries occur on a 250ms interval. This value can be modified by setting the custom property LB_HA_INTERVAL=new_value where the new_value is expressed as milliseconds (1 second = 1000 milliseconds). Fix levels: 8.5.5.25 9.0.5.19
