Modifying or Replacing the Logging Configuration File

You can use the SET LOG CFG command of the IOMOPERATE procedure to replace or modify the logging configuration.
You can modify the logging configuration to do the following:
  • configure a logger with a new or existing appender
  • change a logger level
  • add a new appender
  • remove an appender
Note: SAS ignores the IMMUTABILITY settings of a logger when an administrator modifies a configuration file using the IOMOPERATE procedure or SAS Management Console.
To modify the logging configuration, you create a logging configuration file only with the changes that you would like to make. A complete configuration file is not required. The configuration file must contain the <?xml>, <logging:configuration>, and </logging:configuration> elements. Any time you modify the logging configuration, the <logging:configuration> element must have the modify attribute set to "TRUE". If you are removing an appender, the remove attribute on the appender element must be set to "TRUE". Here is an example of a logging configuration file that is used to associate an existing appender with a logger:
<?xml version="1.0"?>
   xmlns:logging="" modify="true">
  <logger name="App.Program">
    <appender-ref ref="newcons"/>
To replace the logging configuration, you create a new logging configuration file. The <logging:configuration> element must have the modify attribute set to "FALSE" or the modify attribute must not be present in the <logging:configuration> element.
When you modify or replace the logging configuration, the IOMOPERATE procedure might look similar to this:
proc iomoperate uri="iom://localhost:15976;Bridge;TRUSTEDSAS" type=METADATA;
  set log cfg="newcfg.xml";
