今天应用报错，尝试重启db2服务，报错了：

SQL1025N  The database manager was not stopped because databases are still active.

之后执行强制关闭：

[db2inst1@localhost db2dump]$ db2stop force

03/16/2012 14:14:52     0   0   SQL1064N  DB2STOP processing was successful.

关闭成功了

再次启动数据库：

[db2inst1@localhost db2dump]$ db2start     

03/16/2012 14:15:00     0   0   SQL1063N  DB2START processing was successful.

Command Line Processor for DB2 Client 9.7.5

You can issue database manager commands and SQL statements from the command 

prompt. For example:

    db2 => connect to sample

    db2 => bind sample.bnd

For general help, type: ?.

For command help, type: ? command, where command can be

the first few keywords of a database manager command. For example:

 ? CATALOG DATABASE for help on the CATALOG DATABASE command

 ? CATALOG          for help on all of the CATALOG commands.

To exit db2 interactive mode, type QUIT at the command prompt. Outside 

interactive mode, all commands must be prefixed with 'db2'.

To list the current command option settings, type LIST COMMAND OPTIONS.

For more detailed help, refer to the Online Reference Manual.

db2 => connect to newhis

SQL0752N  Connecting to a database is not permitted within a logical unit of 

work when the CONNECT type 1 setting is in use.  SQLSTATE=0A001

类连接设置时，在逻辑工作单元内不允许连接数据库。

解释:
发出 COMMIT 或 ROLLBACK
语句之前，尝试连接另一个数据库或同一个数据库。在 CONNECT 1
类环境内不能处理该请求。

退出执行reset

重新执行就可以了，

[db2inst1@localhost ~]$ db2 connect reset

[db2inst1@localhost db2dump]$ db2 connect to newhis

  

   Database Connection Information

 Database server        = DB2/LINUX 9.7.5

 SQL authorization ID   = DB2INST1

 Local database alias   = NEWHIS

一切正常了

[db2inst1@localhost db2dump]$ db2
