Db2 卸载步骤（参考）linux
开始卸载sql
1. 删除全部数据库。数据库
可使用“控制中心”或drop database命令删除数据库。笔者卸载而未删除数据库，结果是从新安装后没法创建同名数据库。服务器
若要显示全部已建立的数据库能够执行以下命令：app
# db2 list db directoryasync
删除数据库ide
# db2 drop database 数据库名ui
[db2inst1@gxmzd-test-db2 ~]$ db2 list dbdirectoryspa
System Database Directoryorm
Number of entries in the directory = 2
Database 1 entry:
Database alias = GXMZDDB
Database name = GXMZDDB
Local database directory = /home/db2inst1/db2inst1
Database release level = d.00
Comment =
Directory entry type = Indirect
Catalog database partition number = 0
Alternate server hostname =
Alternate server port number =
Database 2 entry:
Database alias = GXMZD
Database name = GXMZD
Nodename = GXMZD
Database release level = d.00
Comment =
Directory entry type = Remote
Catalog database partition number = -1
Alternate server hostname =
Alternate server port number =
执行删除数据库动做
# db2 drop database + 数据库名称
[db2inst1@gxmzd-test-db2 ~]$ db2 dropdatabase
SQL0104N An unexpected token "END-OF-STATEMENT" was found following
"DATABASE". Expected tokens may include: "<identifier>". SQLSTATE=42601
[db2inst1@gxmzd-test-db2 ~]$ db2 dropdatabase GXMZDDB
DB20000I The DROP DATABASE command completed successfully.
[db2inst1@gxmzd-test-db2 ~]$ db2 dropdatabase GXMZD
SQL1428N The application is already attached to "DB2INST1" while thecommand
issued requires an p_w_upload to"GXMZD" for successful execution.
二中止DB2管理服务器：
必需要中止DB2管理服务器才能在linux上卸载DB2。
1.1. 做为DB2管理服务器全部者登录。
1.2. 用db2adminstop命令中止DB2管理服务器
[root@gxmzd-test-db2 home]# su dasusr1
[dasusr1@gxmzd-test-db2 home]$ db2adminstop
SQL4407W The DB2 Administration Server was stopped successfully.
三中止DB2实例：
必需要中止DB2实例才能在linux上卸载DB2。
1.3. 做为具备root用户权限的用户登录。
1.4. 输入/opt/ibm/db2/V9.7/bin/db2ilist命令，获取系统上的全部DB2实例的名称。
1.5. 注销。
1.6. 做为想要中止的实例的全部者登录。
1.7. 进入该用户的主目录下，运行脚本：. sqllib/db2profile
1.8. 输入db2 forceapplication all命令来中止全部数据库应用程序。
1.9. 输入db2stop命令来中止DB2数据库管理器。
1.10. 输入db2terminate来确认DB2数据库管理器已中止。
1.11. 对每个要删除的实例重复以上步骤。
[db2inst1@gxmzd-test-db2 home]$/opt/ibm/db2/V9.7/bin/db2ilist
db2inst1
[db2inst1@gxmzd-test-db2 home]$ cd db2inst1
[db2inst1@gxmzd-test-db2 ~]$ ls
db2inst1 sqllib
[db2inst1@gxmzd-test-db2 ~]$ ll
总用量 8
drwxr-xr-x. 2 db2inst1 db2iadm1 4096 Apr 13 00:32 db2inst1
drwxrwsr-t. 23 db2inst1 db2iadm1 4096 Apr12 11:41 sqllib
[db2inst1@gxmzd-test-db2 ~]$ .sqllib/db2profile
[db2inst1@gxmzd-test-db2 ~]$ db2 forceapplication all
DB20000I The FORCE APPLICATION command completed successfully.
DB21024I This command is asynchronous and may not be effective immediately.
[db2inst1@gxmzd-test-db2 ~]$
[db2inst1@gxmzd-test-db2 ~]$ db2stop
SQL1064N DB2STOP processing was successful.
[db2inst1@gxmzd-test-db2 ~]$ db2 terminate
DB20000I The TERMINATE command completed successfully.
4. 删除DB2管理服务器：
必须删除DB2管理服务器才能卸载DB2。
1.12. 做为DB2管理服务器全部者登录。
1.13. 进入该用户的主目录下，运行脚本：. das/dasprofile.
1.14. 注销。
1.15. 做为root登录，经过输入命令/opt/ibm/db2/V9.7/instance/dasdrop除去DB2管理服务器。
[dasusr1@gxmzd-test-db2 home]$ cd dasusr1
[dasusr1@gxmzd-test-db2 ~]$ ls
das
[dasusr1@gxmzd-test-db2 ~]$ .das/dasprofile
[dasusr1@gxmzd-test-db2 ~]$
[dasusr1@gxmzd-test-db2 ~]$ exit
exit
[root@gxmzd-test-db2 home]#
[root@gxmzd-test-db2 home]#
[root@gxmzd-test-db2 home]#/opt/ibm/db2/V9.7/instance/dasdrop
SQL4410W The DB2 Administration Server is not active.
DBI1070I Program dasdrop completed successfully.
5. 删除DB2实例：
一旦删除系统上的实例，该实例下的全部DB2数据库都将不可用。
1.16. 经过输入/opt/ibm/db2/V9.7/instance/db2idropdb2instname删除实例。
[root@gxmzd-test-db2 home]#/opt/ibm/db2/V9.7/instance/db2idrop db2inst1
DBI1070I Program db2idrop completed successfully.
6. 卸载DB2产品
以root身份登录，到DB2版本产品CD-ROM上的根目录或DB2安装文件（一般就是tar解包文件）下找到 db2_deinstall命令，
运行db2_deinstall －a命令能够删除全部DB2产品。
可能须要输入DB2安装路径，这里是/var/opt/ibm/db2/V9.7
而后也能够在LINUX中删除DB2用户，这并不是必须，从新安装仍可以使用它们。
[root@gxmzd-test-db2 expc]# ls
db2 db2_deinstall db2ls db2setup installFixPack readmefirst.htm
db2ckupgrade db2_install db2prereqcheck doc readmefirst readmefirst.txt
[root@gxmzd-test-db2 expc]# ./db2_deinstall-a
Enter full path name for the installdirectory -
------------------------------------------------
/opt/ibm/db2/V9.7
DBI1016I Program db2_deinstall is performing uninstallation. Please
wait.
The execution completed successfully.

"/tmp/db2_deinstall.log.31318".
[root@gxmzd-test-db2 expc]#
