How to Use Logger Messages

This chapter gives you general information and helpful tips about messages. It covers these topics:

About the Logger Messages

The Oracle Video Server logger messages are generated by various components of the Oracle Video Server system and are written to the log file by the Oracle Media Net logger process, mnlogsrv. For more information about mnlogsrv, see the Oracle Video Server Administrator's Guide for your platform.

The logger messages themselves are stored in the file $ORACLE_HOME/vs21/mesg/mzlm.dat. This document is created from mzlm.dat. However, mzlm.dat contains many informational messages in addition to error or warning messages. Most of these informational messages do not have Cause or Action statements and are not listed in this document, because there is no additional information.

When you start mnlogsrv, you specify the destination of the logger messages. Usually this is a file, but if a file is not specified, logger messages are sent to the console.

To view logger messages as they are written to a file, use the command:

tail -f filename

The filename is the name of the log file.

Recognizing Variable Text in Messages

To help you find and fix errors, Oracle embeds object names, numbers, and character strings in some messages. These embedded variables are represented by num, str, hex, and so on.

For example, the message:

5317 invalid stripe size of num specified for volume `str'

might actually appear as:

5317 invalid stripe size of 12 specified for volume `trailer2'

Abbreviations

These abbreviations may appear in the Messages, Cause, or Action lines.

BLOB - Binary large object

DSM - Down-stream manager

MDS - Media Data Store

OCS - Connection service

PTS - Position time stamp (from tagger)

RPC - Remote procedure call

STB - Set-top box

WWS - Oracle World-Wide Support

Messages Ranges

The Oracle Video Server logger messages are grouped into specific ranges indicating the component that generated the message. The message ranges are:

1-9: Oracle Video Server logger internal messages

200-399: Connection service messages

400-499: BLOB wrap utility messages
