做DB2的插入操作报错
db2 => insert into atmjobsts values ('20090805','2')
DB21034E The command was processed as an SQL statement because it was not a
valid Command Line Processor command. During SQL processing it returned:
SQL0964C The transaction log for the database is full. SQLSTATE=57011
原因：
缓冲池扩展失败，由于可用的虚拟内存的大小不足
-----------------------------------------------------------------------------------------------
解决：
1. 查看
db2 => get db cfg
Database Configuration for Database
...
Log file size (4KB) (LOGFILSIZ) = 10240
Number of primary log files (LOGPRIMARY) = 13
Number of secondary log files (LOGSECOND) = 4
Changed path to log files (NEWLOGPATH) =
Path to log files = /db2data/db2shjh/db2inst1/NODE0000/SQL00001/SQLOGDIR/
Overflow log path (OVERFLOWLOGPATH) =
Mirror log path (MIRRORLOGPATH) =
First active log file =
Block log on disk full (BLK_LOG_DSK_FUL) = NO
Percent max primary log space by transaction (MAX_LOG) = 0
Num. of active log files for 1 active UOW(NUM_LOG_SPAN) = 0
...
2. 修改
后来把这个参数的大小相应调整了一下，调整后如下：
Log file size (4KB) (LOGFILSIZ) = 61440
调整方法为
update db cfg using LOGFILSIZ 61440
3. 调整后重启数据库
执行 db2stop 来停止DB2服务，如果停止不掉可以考虑执行 db2stop force 强制停止。
执行 db2start 启动DB2服务。
4. 查看
Log file size (4KB) (LOGFILSIZ) = 61440
Number of primary log files (LOGPRIMARY) = 13
Number of secondary log files (LOGSECOND) = 4
Changed path to log files (NEWLOGPATH) =
Path to log files = /db2data/db2shjh/db2inst1/NODE0000/SQL00001/SQLOGDIR/
Overflow log path (OVERFLOWLOGPATH) =
Mirror log path (MIRRORLOGPATH) =
First active log file =
Block log on disk full (BLK_LOG_DSK_FUL) = NO
Percent max primary log space by transaction (MAX_LOG) = 0
Num. of active log files for 1 active UOW(NUM_LOG_SPAN) = 0
5. 再执行 插入操作 OK 解决
db2 => insert into atmjobsts values('20090805','3')
DB20000I The SQL command completed successfully.
