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 :
