IKJ56644I NO VALID TSO USERID, DEFAULT USER ATTRIBUTES USED

Explanation
 If RACF® is
installed, a background job will be run using the minimum default
user attributes.  Either the user ID was unidentifiable, or no user
ID was specified as a JOB card parameter, or allocation of the user
attributes data set (SYS1.UADS) failed. Note: An unidentifiable user
ID can be a user ID that is greater than seven characters.

 If RACF or its equivalent is not active,
then the system always issues this message.
