20 Mar 2020 17:31:47,414- Thread: 28 SEVERE [com.vontu.util.jdbc.JDBCLogger] Failed to initialize JDBC Logging
Cause:
java.nio.file.NoSuchFileException: C:\Vontu\Protect\logs\debug\manager_jdbc_0.log.lck
java.nio.file.NoSuchFileException: C:\Vontu\Protect\logs\debug\manager_jdbc_0.log.lck
 at sun.nio.fs.WindowsException.translateToIOException(WindowsException.java:79)


Note that it may not always be the jdbc_0.log.lck but some .lck file has become corrupted.
This may be due to a file system corruption, a server crash, or a backup such as P2V having been made without first stopping the DLP services

Resolution

1. Stop the DLP services see this article for the correct order of DLP service starts
2. Move all of the log files out of the log folders to a backup location, leaving only the log folder and its tomcat, and debug child folders intact
3. Restart the services in the correct order
4. Allow a few minutes for the services to get up and running, then load the console
