DB2 - Problem description

Problem IC78186 Status: Closed

HADR STANDBY MAY TRY TO RETRIEVE LOG FILES EVEN WHEN LOG ARCHIVE METHOD IS
SET TO LOGRETAIN

product:
DB2 FOR LUW / DB2FORLUW / 970 - DB2
Problem description:
HADR standby database may still try to retrieve log files from 
archive device even after userexit is turned off. 
 
 
When hitting the problem, database configuration looks like 
this: 
 Log retain for recovery enabled             (LOGRETAIN) = 
RECOVERY 
 First log archive method                 (LOGARCHMETH1) = 
LOGRETAIN 
 User exit for logging enabled                (USEREXIT) = OFF 
 
Normally, with the above configuration, HADR standby should not 
retrieve log files for local catchup. However, when hitting this 
problem, similar messages could be found in db2diag.log:
