DB2 - Problem description

Problem IC75494 Status: Closed

HEALTH MONITOR FAILS TO DIFFERENTIATE BETWEEN HADR PRIMARY AND SECONADRY
AFTER HADR TAKEOVER.

product:
DB2 FOR LUW / DB2FORLUW / 950 - DB2
Problem description:
Health monitor, when configured with HADR, throws errors after 
HADR takeover. We need to fix the gap between HADR and Hmon, 
hmon is not working in HADR environment. Health monitor is mot 
able to pick up the new primary after HADR takeover and it 
continues to assume the old primary as a primary (which is 
standby actually). db2acd should indicate that DB is inactive to 
all plugins hosted within acd. 
 
Here are few sample error messages in db2diag.log after take 
over :

Hence, the gap between Health monitor and HADR needs to be 
bridged.
