Explanation
 The connection name (CONNAME= ) that JES2 passed
to XES is not valid. JES2 creates the connection name by concatenating
the string ‘JES2_’ with the name of the local member as specified
on either the OWNMEMB= parameter of the MASDEF initialization statement
or the default name specified as the SID specification in the MVS
SMFPRMnn PARMLIB member.

System programmer response
 Ensure that the value specified on
the OWNMEMB= parameter is valid and contains characters that are valid
as a XES connection name.  Correct the OWNMEMB= value if necessary
and allow JES2 to attempt to reconnect the member. For MASDEF OWNMEMB=
naming convention information and for the SMFPRMnn PARMLIB member,
see z/OS MVS Initialization and Tuning Reference.
