Issue the following command below to extract information about transactions log.

db2 get db cfg for sample

....

 Log file size (4KB)                         (LOGFILSIZ) = 1000
 Number of primary log files                (LOGPRIMARY) = 3
 Number of secondary log files               (LOGSECOND) = 2
 Changed path to log files                  (NEWLOGPATH) =
 Path to log files                                       = C:\DB2\NODE0000\SQL00
002\SQLOGDIR\
 Overflow log path                     (OVERFLOWLOGPATH) =
 Mirror log path                         (MIRRORLOGPATH) =
 First active log file                                   = S0000002.LOG
 Block log on disk full                (BLK_LOG_DSK_FUL) = NO
 Percent of max active log space by transaction(MAX_LOG) = 0
 Num. of active log files for 1 active UOW(NUM_LOG_SPAN) = 0

...

With the output above you can extract a lot of information about transactions logs:

Total of log file size:

 Number of primary log files                 (LOGPRIMARY) = 3
 Number of secondary log files               (LOGSECOND) = 2

________________________________________________________
                                                                                 5

Now, you have to multiple the followings values:

Log file size (4KB)                         (LOGFILSIZ) = 1000

4KB*1000 = 4000 KB

Finally, multiply the sum of LOGPRIMARY and LOGSECOND variables by 4000KB, you will have:

4000KB*5=20000KB or 20MB

So, the space reserved for transactions log file is 20MB

What is the First active log file  ?

In the output above you can find the following parameter:

First active log file                           = S0000002.LOG

So, the first active log file is S0000002.LOG

What is the Path to log files  ?

In the output above you can find the following parameter:

Path to log files                                       = C:\DB2\NODE0000\SQL00
002\SQLOGDIR\

So, the path to log file is C:\DB2\NODE0000\SQL00002\SQLOGDIR\
