如何在DB2中找出当前的事务日志大小？

Question

如何找出当前的事务日志大小？是否可以通过查询一些带有SQL的系统表来做到这一点？找出事务日志的最大大小也很有趣.

是从文件系统查找的唯一选项吗？

Answer 1

该GET DATABASE CONFIGURATION命令会给你一个数据库中的所有配置信息.

它包括有关日志文件大小,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
