db2 备份与恢复问题01

db2 backup ... INCLUDE  LOGS是v8.2后的参数
怎样确实一个备份介质中是否有日志????????
db2ckbkp -H 这个命令可以看备份文件是否INCLUDE  LOGS
----------------------------------------------
$ db2 restore db tt from /bk taken at 20080103122136 logtarget /home/db2
DB20000I  The RESTORE DATABASE command completed successfully.

$ db2 rollforward db tt query status

                                 Rollforward Status

Input database alias                   = tt
Number of nodes have returned status   = 1

Node number                            = 0
Rollforward status                     = DB  pending
Next log file to be read               = S0123231.LOG
Log files processed                    =  -
Last committed transaction             = 2008-01-03-12.21.36.000000


$ db2 rollforward db TYDB to 2008-01-03-12.21.36.000000 using local time and stop
SQL1275N  The stoptime passed to roll-forward must be greater than or equal to
"2008-01-03-12.11.36.000000", because database "tt" on node(s) "0" contains
information later than the specified time.
$ db2 rollforward db tt to 2008-01-03-12.21.36.000000 using local time and stop
SQL1268N  Roll-forward recovery stopped due to error "24" while retrieving log
file "S0123231.LOG" for database "TYDB" on node "0".
$db2 rollforward db tt query status
                                 Rollforward Status
Input database alias                   = tt
Number of nodes have returned status   = 1
Node number                            = 0
Rollforward status                     = DB  working
Next log file to be read               = S0000232.LOG
Log files processed                    =  -
Last committed transaction             = 2008-01-03-12.21.36.000000

又要S0000232.LOG日志了，我的想法是备份前的某一事务提交的记录跨了两个日志文件了，现在怎么办？

db2 rollforward ... NORETRIEVE
