Hello Manideep,
After seeing your log files, Your password has been expired for the database/schema of the project you are using/accessing.
The easiest way to fix is change the password for that database/schema(utaf_utaf_dashboard_db) back to what the password was originally then make it so that the password does not expire. Otherwise, you would have to change the password on that project database, then ''remove'' the project from ALM then change the password in the dbid.xml file and then ''restore'' the project in ALM.
we always recommend that you please make the ALM databases so that the passwords do not expire, this does not happen.
