GET DATABASE CONFIGURATION命令将为您提供有关数据库的所有配置信息。

它包含有关日志文件大小，主日志文件和辅助日志文件的数量等信息。下面的示例输出。

Log file size (4KB)                         (LOGFILSIZ) = 1024
Number of primary log files                (LOGPRIMARY) = 13
Number of secondary log files               (LOGSECOND) = 4
Changed path to log files                  (NEWLOGPATH) =
Path to log files                                       = D:\DB2\NODE0000\SQL00003\SQLOGDIR\
Overflow log path                     (OVERFLOWLOGPATH) =
Mirror log path                         (MIRRORLOGPATH) =
First active log file                                   =
Block log on disk full                (BLK_LOG_DSK_FUL) = NO
Block non logged operations            (BLOCKNONLOGGED) = NO
Percent max primary log space by transaction  (MAX_LOG) = 0
Num. of active log files for 1 active UOW(NUM_LOG_SPAN) = 0
