Answer 1

1、一般情况是配置的数据库名不对，进入服务器。切换到用户，例如我的是**su - db2inst1**
2、查看当前的库名：db2inst1@kf4:~>** db2 list db directory**
内容如下:

System Database Directory

Number of entries in the directory = 1

Database 1 entry:

Database alias = SAMPLE
Database name = SAMPLE
Local database directory = /home/db2inst1
Database release level = d.00
Comment =
Directory entry type = Indirect
Catalog database partition number = 0
Alternate server hostname =
Alternate server port number =
3、修改为库名SAMPLE，成功连接
