DB2数据库实例创建与删除 学习笔记

以root身份执行 $DB2HOME/instance/db2idrop -f 实例名,注意一定要加-f,否则不会删除实例下面sqllib文件。如果不幸忘了,执行db2icrt,会报sqllib文件存在的错误,即使先删掉这个文件也不行,执行一下db2icrt,就会生成一部分sqllib,进入死胡同,这个是由于用实例用户登录造成的,也许有个db2profile文件在登录时搞怪,该怎么办呢?看我的吧!用一个非实例的用户登录,su成root,然后再删掉sqllib,试试再db2icrt,问题解决了:)

创建db2 实例和创建库的方法大致分为两类!一类是图形界面db2setup 创建一种是CLI创建!此处只描述一下CLI方式至于图形界面请大家搜索一下吧!
db2 创建实例 创建数据库

1.创建实例用户
mkdir /db2/db2test 创建实例用户目录
smitty user
选择Add a User
* User NAME                                          [db2test]                                                             
User ID                                                   []                                                                    
ADMINISTRATIVE USER?                       false                                                               
Primary GROUP                                     [db2iadm1]                                                           
Group SET                                           [staff]                                                              
ADMINISTRATIVE GROUPS                   []                                                                   
ROLES                                                         []                                                                   
Another user can SU TO USER?            true                                                                
SU GROUPS                                          [ALL]                                                                
HOME directory                                     [/db2/db2test]
Initial PROGRAM                                    [/usr/bin/ksh]


2.创建实例 DB2_install=/usr/opt/db2_08_01/instance
./db2icrt -u db2test db2test


3.创建数据库
su - db2test
db2start     #此处不执行启动实例将报:SQL1032N No start database manager command was issued. SQLSTATE=57019
db2 create db db2test


4.删除数据库
db2 drop db db2test
db2stop


5.删除实例
cd DB2_install
./db2idrop -f db2test # -f参数一定要添加否则删除完了会报错!


6.删除用户
smitty user
选择Remove a User
* User NAME                                          [db2test]                                                           +
Remove AUTHENTICATION information?                  yes      

删除用户目录
rm -rf db2test
