VM65975: CP SEND COMMAND TO PSF PRINTER FAILS

Obtain the fix for this APAR.

APAR status

• Closed as program error.

Error description

• The CP SEND <prtid> function is used by PSF/VM (and other
  distributed services) to allow one VM user, like the Spool
  File Conversion Machine (SFCM), to notify another VM user,
  like the Printer Driver Machine (PDM) of an event such as the
  arrival of a new spool file to be processed. After an upgrade
  from z/VM 6.1 to z/VM 6.3, a customer noticed SFCM failed to
  notify PDM and required additional intervention to print.
  When a new spool file arrives on an empty print queue, the
  printer driver does not automatically respond.  It must be
  started by a manual operation (which could be as simple as a
  query).
  

Local fix

• A circumvention is possible with automation to send a status
  request to the printer driver on a regular basis.

Problem conclusion

• For SSI support in z/VM 6.2 the SEND command was enhanced to
  support remote SCIF over ISFC through a new 'AT' operand.  The
  required changes to the command parsing introduced a logic flaw
  that altered a couple of registers that were needed when
  the command was intended for a print server.  Instead of
  delivering the message, SEND failed with an error (HCPSEC045E).
  To address this problem, the registers are restored before
  the code forks to call HCPXSSSE (user) or HCPAPXSD (printer).
