Hi,

when debugging applications based on CDO (incl. the Hibernate Store) the
logging output can be a bit overwhelming.

How and where can I control the logging output generated by CDO and Net4J?

What are good strategies to keep the logging output of your own app
separate from the logging output generated by the underlying frameworks?

Thanks,
Goetz

Our Operations & Maintenance (OM) platform distinguishes between logging important events and tracing debug
informations. While log events can not be suppressed, traces can be configured in a fine grained manner through the
normal OSGi mechanisms, e.g., the Tracing tab of a launch configuration or the .options file of a product.

*But*: Both log and (enabled) trace events can be handled in custom ways by adding or removing OMLogHandlers and
OMTraceHandlers to/from the OMPlatform.INSTANCE:

org.eclipse.net4j.util.om.OMPlatform.isDebugging()
org.eclipse.net4j.util.om.OMPlatform.setDebugging(boolean)
org.eclipse.net4j.util.om.OMPlatform.addLogHandler(OMLogHandler)
org.eclipse.net4j.util.om.OMPlatform.removeLogHandler(OMLogHandler)
org.eclipse.net4j.util.om.OMPlatform.addTraceHandler(OMTraceHandler)
org.eclipse.net4j.util.om.OMPlatform.removeTraceHandler(OMTraceHandler)

You can easily remove the default org.eclipse.net4j.util.om.trace.PrintTraceHandler.CONSOLE and/or add a custom trace
handler that writes traces to a file:

org.eclipse.net4j.util.om.trace.PrintTraceHandler.PrintTraceHandler(PrintStream)

BTW., OMPlatform.INSTANCE.setDebugging(false) disables trace events altogether.

Please also note that all OM facilities (logging, tracing, monitoring, preferences, etc.) work with or without OSGi.
That's the whole purpose of the OM framework.

You should write and register your own trace handlers with the OMPlatform and possibly remove the default one.

Hi Eike,

thanks for the hints. I made some progress, but still keep getting too
much logging output.

For context: I am using CDO with the Hibernate Store. So this might also
be a question for Martin Taal.

Here is what I tried to get rid of the logging output:

1) I imported the net4j projects as source, found the .options files and
reconfigured the debug options to "false".

2) When starting the CDO Hibernate Server I switch tracing off in the
launch configuration.

3) In my application, which is acting as a CDO client, I inserted
OMPlatform.INSTANCE.setDebugging(false);

However, I keep getting logging output. I am pasting examples below.

Any hints where I could look?

There are some parts in the application that are using log4j so I
suspected that output might be coming from there, but reconfiguring the
log4j.properties file did not make any difference.

Thanks,
Goetz

Hi Goetz,

The traces (not logs) definitely come from Net4j and CDO. So you must have made a mistake when you tried to disable
them. I recommend to set breakpoints at your OMPlatform.INSTANCE.setDebugging(false) statement and some of the
TRACER.trace() calls, e.g., in org.eclipse.net4j.util.lifecycle.Lifecycle.

Note that yo udon't necessarily need the sources to change the tracing options.
http://wiki.eclipse.org/FAQ_How_do_I_use_the_platform_debug_tracing_facility%3F says:

"Finally, you need to enable the tracing mechanism by starting Eclipse with the -debug command line argument. You can,
optionally, specify the location of the debug options file as either a URL or a file-system path after the -debug
argument. "

Cheers
/Eike
