I check error log. log files located in the data directory, ifound the below errors,
[root@TEST-R data]# tail -f TEST-R.err /db/mysql/app/bin/mysqld: Can't create/write to file '/db/mysql/tmp/ib3xHqRO' (Errcode: 2)

Can any one give me the solution how to fix this issue.

The error you quoted clearly indicates the problem, InnoDB cannot create file /db/mysql/tmp/ib3xHqRO because there is no such file or directory (errcode 2). The solution is up to you, either create the folder beforehand, or point your server to already existing location.
