Does database services are started ?

have you try to repair the SEPM

1. Browse to conf.properties by navigating through

%Program Files\Symantec\Symantec Endpoint Protection Manager\tomcat\etc\conf.properties
2. Edit Conf.properties
3. Add scm.db.datasource= jdbc/metadatabase at the last line (There will be a space after the equal sign)
4. Save the file

Execute Management Configuration Wizard.

Once the Management Configuration is complete. Symantec Endpoint Manager services would be started and you should be able to login to SEPM console.
