 APAR NUMBER: IX79294            RESOLVED AS: PROGRAM ERROR

 ABSTRACT:
 IX79294: ANR9999D ADMNODE(6648): INVALID NODE TYPE 0 FOR NODE ...


 ORIGINATING DETAILS:
 This APAR is to document this message and let customers know
 that this message may be ignored.  This message is issued as a
 result of code added in level 3.1.0.2 and 3.1.1.1 to correct a
 problem where server nodes were counted against the number of
 clients licensed.
 ANR9999D is a diagnostic message which should only be issued
 when there is a problem which requires further diagnosis or
 corrective action by ADSM Service.  In this case, it is an
 inappropriate use of the message because the server is
 actually correcting an existing problem and no further action
 or diagnosis is required.
 Customers should ignore this particular ANR9999D message.
