Using the Oracle BI Presentation Services Logging Facility

By default, Oracle BI Presentation Services is configured to log all error events and informational and warning events of sufficient importance. An example of an important informational event would be a server starting up or a server shutting down. Log files are named sawlogxx.log, where the xx is replaced by an incremented number.

To debug specific issues that a user may be encountering, the logging level can be increased to log more information than the default configuration. For example, while debugging a particular Oracle BI Presentation Services connectivity issue, it might be useful to increase the maximum logging on the saw.odbc log source only. This adds detailed logging for that component, without cluttering the log with detailed logging from other events. Another example is to create a new log writer that records only chart events. For an illustration of this example, see Figure 5.

CAUTION:  Do not increase the logging on a production implementation, except to diagnose specific issues. Logging affects performance.

All Oracle BI Presentation Services configuration information is loaded from the file logconfig.xml, located in the following directory (based on operating system platform):

• Windows:

  SADATADIR/web/config

• UNIX:

  SADATADIR/web/config

where SADATADIR is the Oracle BI Presentation Services data directory.
