Symptoms

In Oracle Application Server 10gR3 or OC4J based environment, the main log file file log.xml stops collecting information and is not updated anymore.

Changes

The problem occurs when in ASControl, the log level for the logger "oracle" has been set to NULL voluntarily or accidentaly.

After setting it back the log level to its original value, or to any other log level as INFO, CONFIG, WARN, etc .. the logging functionality does not recover and the log file still does not receive any logged message.

The problem can be reproduced for testing very easily with following actions:

1) Create a testing oc4j instance

is inserted, but there is no "<handler" tag any more. 

As there is no handler associated to the logger, the log file will never be populated with logging information.
