#/opt/IBM/db2/VXX.Y/instance/db2ilist ###这里是root用户执行
#su –
$db2 list db directory
上面示例显示如何获得实例和数据库,根据你安装db2软件的目录和版本不同,命令的位置可能不同。找到实例和数据库后,先删除数据库,再停止实例,最后删除实例。过程一般如下
$db2 drop db
$db2stop force
$exit
#/opt/IBM/db2/VXX.Y/instance/db2idrop ###这里是root用户执行
2、上面做完后,可以删除db2软件了
#/opt/IBM/db2/VXX.Y/install/db2_deinstall ###这里是root用户执行
根据提示输入安装目录后,这个脚本会执行删除操作
3、最后,可以看下安装目录下是否有残留文件和目录,可以直接rm删掉。
上面的步骤是单机的DB2删除过程。现在DB2有hadr、purescale集群等环境,在这些环境下清除步骤就更复杂裂态了,这里先不写了。
