unix 安装db2 大家有遇到类似的问题吗？怎么解决啊。
ERROR:An error occurred while running the command
"/home/db2inst1/sqllib/bin/db2 CREATE TOOLS CATALOG SYSTOOLS USE EXISTING
DATABASE TOOLSDB FORCE" to initialize and/or migrate the DB2 tools catalog
database. The return value is "4".

Creating DB2 tools catalog:.......Failure
WARNING:A minor error occurred while installing "DB2 Enterprise Server Edition"
on this computer. Some features may not function correctly.


------解决方案--------------------------------------------------------
是安装介质有问题还是 系统设置问题？看下安装日志吧
------解决方案--------------------------------------------------------
是用户的问题吧，我已将好像碰到过，忘记怎么解决的了。
------解决方案--------------------------------------------------------
TOOLSDB 是DB2辅助功能（如自动备份）所用的系统库
看错误提示是初始化此库时出错
是不是安装所用帐户的权限问题，如磁盘、目录操作权限
------解决方案--------------------------------------------------------
