Explanation
 VTAM® issues
this message when the library member COSAPPN was empty, not
found, or contained a syntax error.
 library is
the data definition name (DDNAME) specified for the definition library.
 errortype indicates
the type of error and can be IS EMPTY, NOT FOUND, or IN
ERROR (contains a syntax error).

System action
 VTAM initialization
continues.  However, the IBM-supplied classes of service may not be
available for APPN route selection.

Operator response
 If the APPN classes of service have been
defined under a different member name and are activated by configuration
list processing or by a VARY ACT command, then no action is necessary.
 Otherwise,
save the system log for problem determination. 

System programmer response
  If IS EMPTY or NOT FOUND is displayed, verify that
COSAPPN was either intentionally left empty or not found.
If IN ERROR is displayed, see the z/OS Communications Server: SNA Resource Definition
Reference for additional information.

 Note: If an alternate set of appropriate classes of service
is not defined through another configuration file specified in the
start options, attempting to activate APPN sessions will yield unpredictable
results.
