STDOUT DD information in MFASTC disappears after maintenance


Article ID: 247483


Updated On:


Advanced Authentication Mainframe


Prior to applying AAM maintenance,  the STDOUT DD in MFASTC provided trace data useful for debugging, but this is no longer produced.  

An example of the output:

Release : 2.0

Component : Advanced Authentication Mainframe


If the customer had previously set the level for MFA_STDOUT in logback.xml, in rare instances maintenance may have overwritten this customization.


The details on tracing are in our doc on this page under the sub-title

(Optional) Configure Tracing for the Advanced Authentication Mainframe Java Component

Configure tracing by updating logback.xml in /MFASTC/directory if needed. logback.xml is an ASCII file and must be updated in ASCII format. Review the following options and update if desired.

<root level="INFO"> Determines the log level. The five levels are (ERROR, WARN, INFO, DEBUG, and TRACE). These levels are in order from the least amount of information logged (ERROR) to the most (TRACE). Default: INFO

<file> Contains the path and the name of the file to which the log data is sent. Default:  FASTC/directory/logs

<FileNamePattern> Determines where to archive log files and the name format. The default path is MFASTC/directory/logs. (%i is the index where the index ranges from what is specified by

<MinIndex> and <MaxIndex>.) The default values of <MinIndex> and <MaxIndex> are 1 and 20 respectively.

<MaxFileSize> Specifies how large the file can get before the file resets and archives. Default: 50 MB
