DB2 FOR LUW / DB2FORLUW / A50 - DB2

When there are many current and incoming connections to the HADR
primary database, the takeover hadr command could sometime
return SQL1770N rc7.

During hadr takeover, the primary database has to force off
current connections and block incoming connections from
entering. When there are too

many connections the process might take too long and eventually
timeout, causing takeover to fail on the standby database.

The following diagnostic message can be found in db2diag.log on
standby:
