The sample db2.conf file is as follows:

#
# The following settings are used by Backup Exec to perform
# an alternate restore or a rollforward of a DB2 database during a
# a DBA-initiated operation using Backup Exec's vendor dll
# db2sqluv.dll or user exit program db2uext2.exe.
# Reminders:
#
# Uncomment the following lines by removing the # preceding every line
# and add appropriate data to perform an alternate restore/rollforward 
# operation. 
# You can add more blocks for any additional alternate restore/rollforward 
operations.
