安装完成后，欲登陆sample数据库和toolsdb，发现出错：
- db2 => connect to sample
- SQL1031N The database directory cannot be found on the indicated file system.
- db2 => connect to toolsdb
- SQL1031N The database directory cannot be found on the indicated file system.
1、 猜想数据库未安装，查看/hom/db2inst1目录下的，仅有sqllib文件夹：
- [db2inst1@localhost ~]$ ls
- sqllib
对比下其他学员的情况，发现本人的服务器上少了一个db2inst1目录：
- [db2inst1@localhost ~]$ ls
- b2inst1 sqllib
2、下面手动对两个数据库进行创建：
2.1、创建示例数据库：
- [db2inst1@localhost ~]$ db2sampl
- Creating database "SAMPLE"...
- Connecting to database "SAMPLE"...
- Creating tables and data in schema "DB2INST1"...
- Creating tables with XML columns and XML data in schema "DB2INST1"...
- 'db2sampl' processing complete.
2.2、创建toolsbd数据库：
- [db2inst1@localhost NODE0000]$ db2 create tools catalog systools create new database toolsdb
- DB20000I The CREATE TOOLS CATALOG command completed successfully.
2.3、确认相应数据库文件创建的情况：
- [db2inst1@localhost NODE0000]$ cd
- [db2inst1@localhost ~]$ ls
- db2inst1 sqllib
- [db2inst1@localhost ~]$ cd db2inst1/
- [db2inst1@localhost db2inst1]$ ls
- NODE0000
- [db2inst1@localhost db2inst1]$ cd NODE0000/
- [db2inst1@localhost NODE0000]$ ls
- SAMPLE SQL00001 SQL00002 sqldbdir TOOLSDB
2.4、登陆数据库。首先登陆到sample，然后断开与该数据库的连接，再连接到toolsdb：
- [db2inst1@localhost NODE0000]$ db2
- (c) Copyright IBM Corporation 1993,2007
- Command Line Processor for DB2 Client 9.7.1
- 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 sample
