Db2diag.log Severe msg db2fmp, common communication sqlccipcdarihandshake

Question

I am new to SAP and DB2 as a Netweaver Administrator of a new project.  We do not have anyone who has experience on the following messages on the db2dialog.log.
Is is normal to see lots of the following messages during a DB2 offline backup on the ECC server?
2006-11-18-22.00.49.xxxxxx-480 I457336A288        LEVEL: Severe
PID     : xxxxxx               TID  : 1           PROC : db2fmp (idle) 0
INSTANCE: db2dss               NODE : 000
FUNCTION: DB2 UDB, common communication, sqlccipcdarihandshake, probe:3
RETCODE : ZRC=0x83000024=-2097151964
There is a warning message before these messages:
2006-11-18-22.00.49.422496-480 I456932A403        LEVEL: Warning

MESSAGE : Bringing down all db2fmp processes as part of db2stop

Thanks a lot.                                 ....

Hi,
I assume you have scheduled the offline backup in the SAP system.
Because the application servers are connected permanently to the database offline backups cannot be done without forcing of all connected appliations. On SAP systems this is achived by a db2stop force call before performing the offline backup.
The call to db2stop force is the reason for the errors and warnings you see during an offline backup of a SAP system.
As an alternative to offline backups you should evaluate the usage of online backup or online backups include log files.
