删除目录：C:\ProgramData\IBM\DB2
删除目录C:/program files/SQLLIB若是存在(个人是c:/IBM/SQLLIB)，

 

## 2017更新, 直接使用db2_deinstall删除db2

参考: https://www.ibm.com/support/knowledgecenter/SSEPGG_9.7.0/com.ibm.db2.luw.admin.cmd.doc/doc/r0023670.html

最终使用了/opt/ibm/db2/v10.5/install/db2_deinstall -a
.

Example

To uninstall all the DB2 database products that are installed in a location (DB2DIR), issue the db2_deinstall command located in the DB2DIR/install directory:

DB2DIR/install/db2_deinstall -a

Usage notes

• If you run db2_deinstall -a -f sqllib, the $HOME/sqllib directory will be removed. Be certain to backup any files, that require saving, from this directory prior to running the command.
