I am running DB2 v8.1 FP 16 (Db2 v8.2.9) and I am implementing HADR using 2 sample databases between 2 identical servers (AIX 5.3).

Checking on DB2 Control Center everything seems to be ok, both are in peer mode, and after issuing the commands on primary I have:
b2hawk@hawk:/home/db2hawk:>db2pd -hadr -alldbs

Database Partition 0 -- Database SAMPLE -- Active -- Up 0 days 00:12:19 -- Date 04/21/2008 11:28:49

On the standby database I have:

Also I inserted couple rows on SAMPLE db on the PRIMARY side and after stopping HADR on STANDBY side I was able to browse and see those rows using control center.

I issued the command db2 list utilities on SATNDBY side and I got:
db2hawk@elmer2:/home/db2hawk/scripts:>db2 list utilities

ID = 10
Type = ROLLFORWARD RECOVERY
Database Name = SAMPLE
Partition Number = 0
Description = Database Rollforward Recovery

I have 2 major issues:
1) I would like to stop (and I did it) HADR on either both side oir standby side and try to acces it..I can access it via Control Center but not from db2 connect command on CLP. Also I would like to have this database in STANDARD mode so that I could use it ...
But it doesn't work, every time I try to connect to got the message saying that it is not allowed in HADR mode etc
2) I would like to be able to switch roles or take over but it always failes woth the same error:
SQL01770 Reason Code 4 (and I tried from both side on Control Center)

Please help me

Thanks

always execute command sin command window to see the correct /complete message
go on standby machine and issue
db2 takeover hadr ..... (see command ref for details)
db2 stop hadr should stop hadr and rollforward complete should make the standby db available
