Check with your DBA to verify below:

  • Any port changes happened on Database side.
  • In WCC server, try ping, nslookup, telnet  to Database server 
  • In WCC server, check the DB connection using MSSQLServer Management Studio(in case of SQL Server), tnsping <SId>(in case of Oracle)

If all looks good, try restarting the DB and WCC Servers.
