Report server configuration issue

Hi Members,

I am facing a issue in configuring report server. Report server is installed and successfully running with out any error. while configuring report server in MWS datasoruce is throwing below error

QE-DEF-0325 The logon failed for the following reason:RQP-DEF-0068 Unable to connect to at least one database during a multi-database attach to 1 database(s) in: SAG_TradingNetworks UDA-SQL-0031 Unable to access the “SAG_TradingNetworks” database.UDA-SQL-0107 A general exception has occurred during the operation “attach”.Error while trying to retrieve text for error ORA-01804

Any one faced the same issue, I have already add ORA_TZFILE in environment setting

But think that it’s not working properly
