 process-name

  Specifies the name of the process to which the connection is  to  be
  made.    Process  names  can  contain  from  1  to  15  alphanumeric
  characters.  If a connection to  the  specified  process  cannot  be
  made,  an  error  message  is  displayed.  You cannot connect to the
  process if:

  o  The process is your current process

  o  The process is not part of your current job

  o  The process does not exist

  If you specify the /IDENTIFICATION qualifier,  you  cannot  use  the
  process  name parameter.  If you omit the /IDENTIFICATION qualifier,
  you must specify a process name.

/IDENTIFICATION

 /IDENTIFICATION=pid

 Specifies the process identification (PID) of the  process  to  which

  error message is displayed.

  When you use the  /IDENTIFICATION  qualifier,  do  not  specify  the
  process  name parameter.  If you omit the /IDENTIFICATION qualifier,
  you must specify a process name.
