Hi,
   Recently, the CSS stop connecting to MySQL data base. It gives an error,
 
2018-10-09 16:18:24.264 WARNING [Thread 48] org.csstudio.trends.databrowser3.archive.ConnectJob (run) - Cannot connect to archive jdbc:mysql://localhost/archive

I am not even able to set database password in CSS Applications->Trends->RDBArchive.


Thanks
Vishnu
