But, when I start using 'db2start' it throws the following error

I installed DB2 using 'root' and starting 'DB2' from 'instance' (sathish in this case)

This problem generally occurs if you have recently changed the password of the account which is the owner of that db2 instance what you need to do is go to services-> properties of the db2 instance -> and then from log on part select local system account
如果您最近更改了该 db2 实例所有者帐户的密码，通常会出现此问题，您需要做的是转到服务-> db2 实例的属性-> 然后从登录部分选择本地系统帐户

This looks like something is wrong with the installation. There should be some hints on what DB2 ran into in the db2diag.log file (look under ~/sqllib/db2dump/db2diag.log).
这看起来像是安装有问题。db2diag.log 文件中应该有一些关于 DB2 遇到的问题的提示（查看 ~/sqllib/db2dump/db2diag.log）。
What you could do if the db2diag.log does not provide a clue is to verify your installation is correct. DB2 includes a tool for that named "db2val". Here is the link to the documentation of db2val for version 9.7. Just run "db2val" as the instance owner and check the output.
如果 db2diag.log 没有提供线索，您可以做的是验证您的安装是否正确。DB2 包含一个名为“db2val”的工具。这是9.7 版 db2val 文档的链接。只需以实例所有者身份运行“db2val”并检查输出。
