DB2 FOR LUW / DB2FORLUW / B10 - DB2

There is a boundary condition during online backup where the
database on some member is in the process of performing log file
registration.
If the database encounters this timing window, the online backup
fails with error (SQL0901N) and you
may see db2diag.log messages like bellow.

-Before issue the backup, customer can run a small transaction
(eg. insert one row into a dummy table) from every member.  This
should avoid the boundary condition that triggers the problem.

-The following query can be used to detect boundary condition:

    select MEMBER, LOG_WRITES from
table(mon_get_transaction_log(-2))

If any member returned a value of 0 for LOG_WRITES, it means
that member has not written any log records to disk (so likely
no update transaction has executed on that member).  If ALL
member return non-zero value, BACKUP command should not run into
this issue.
