In addition to the header, you can direct tblog to display the following
information:
■ Copies of blobpages from blobspaces (copied from the logical log
backup tape only, not available from disk)
■ Logical log record header and data (including copies of blobs stored

If tblog detects an error in the log file, such as an unrecognizable log type, it
displays the entire log page in hexadecimal format and terminates.
