## Interface TraceManager

- All Superinterfaces:
    ServiceManager
  All Known Implementing Classes:
    FBTraceManager

      public interface TraceManager
      extends ServiceManager

  Implements the Trace/Audit API available new in Firebird 2.5.

  This functionality includes:

  - Starting a new trace session
  - Stopping an existing trace session
  - Suspending an existing trace session
  - Resuming a suspended trace session
  - Retrieving a list of trace sessions

    Methods
    Modifier and Type | Method and Description
    --- | ---
    `java.lang.Integer` | `getSessionId(java.lang.String sessionName)` Gets the sessionId for the given name.
    `void` | `listTraceSessions()` List all currently registered trace sessions
    `java.lang.String` | `loadConfigurationFromFile(java.lang.String fileName)` Deprecated. We suggest you use standard Java functionality instead (eg `new String(Files.readAllBytes(Paths.get(fileName)), Charset.defaultCharset())`. This method will be removed in Jaybird 4.
    `void` | `resumeTraceSession(int traceSessionId)` Resumes a trace session with the given trace session ID
    `void` | `startTraceSession(java.lang.String traceSessionName, java.lang.String configuration)` Starts a trace session with an optioanl trace session name and configuration
    `void` | `stopTraceSession(int traceSessionId)` Stops a trace session with the given trace session ID
    `void` | `suspendTraceSession(int traceSessionId)` Suspends a trace session with the given trace session ID

      Parameters:
        `traceSessionName` - The trace session name (optional)

      Parameters:
        `traceSessionId` - The trace session ID
      Throws:
        `java.sql.SQLException`

    - #### resumeTraceSession

          void resumeTraceSession(int traceSessionId)
                                  throws java.sql.SQLException

      Resumes a trace session with the given trace session ID
      Parameters:
        `traceSessionId` - The trace session ID
      Throws:
        `java.sql.SQLException`

    - #### listTraceSessions

          void listTraceSessions()
                                 throws java.sql.SQLException

      List all currently registered trace sessions
      Throws:
