Chapter 14. Using logging and tracing features

One of the tasks of the WebSphere Partner Gateway administrator is to help

diagnose problems that arise when documents are being processed. Logging and

tracing are the tools that are used in the diagnosis of the problems. The

administrator needs to know how to configure the system so it can provide the

information needed to diagnose problems.

WebSphere Application Server provides sophisticated logging and tracing

capabilities that are available to applications that it hosts. WebSphere Partner

Gateway components are applications that are hosted by WebSphere Application

Server, and they use the WebSphere log and trace capabilities.

WebSphere Application Server documentation contains general information about

configuring logging and tracing, but in order to use it for WebSphere Partner

Gateway, there are many specific things that you need to know. In this chapter,

you will find a summary of the important items you need to know about using the

WebSphere Application Server console to control logging and tracing. In addition

to this general information, you will also find the specific items about using

logging and tracing to solve WebSphere Partner Gateway problems.

Log and trace files

The log and trace files used for WebSphere Partner Gateway are described in this

section:

SystemOut.log and SystemErr.log

Log messages are written whenever an application writes to the standard

output stream or standard error stream. Application developers can write

messages to these streams to provide general information about the status

of the programs. For example, when an application is starting up, log

messages are often provided to verify that the subsystems used by the

application have been accessed, and that the application itself has started.

When Exceptions occur, these are recorded in the form of a log message by

the application that detected the Exception. The stack trace showing the

state of the system when an Exception occurred is saved by writing it to

the standard error stream.

Log messages are written to the following WebSphere Application Server

files:

SystemOut.log

which records messages written to the standard output

stream.

SystemErr.log

which records messages written to the standard error

stream.

There is not a way to filter log messages so that only some are written and

others are omitted. Since they are always written, log messages tend to be

short and general in nature. Often they are useful because they do provide

information about the status of the system and they can give you hints

about what kind of detailed tracing you should use when a problem

occurs.

Trace file

Unlike log messages, trace messages are only written by applications when
