This appendix describes ZMCS message types that can be received while executing
MEDIASRV commands programmatically:
MEDIASRV Startup Messages
A MEDIASRV process generates these text messages in response to the indicated
error conditions encountered during process startup (before the process enters its
routine processing cycle). After issuing the message, MEDIASRV calls the Guardian
PROCESS_STOP_ procedure.
The MEDIASRV process writes the message to its home terminal. If a home terminal
was not specified in the RUN command, the default is the terminal running the
command interpreter. If a home terminal was not specified in a PROCESS_CREATE_
procedure call, the default home terminal is the home terminal for the process calling
the procedure. If a terminal has other processes controlling it (a command interpreter,
for example), the text messages issued by the MEDIASRV process appear only when
the process controlling the terminal relinquishes control. If you let the home terminal
default to the home terminal of the process issuing the RUN command or
PROCESS_CREATE_ procedure call, you might not know where the error messages
will appear. Because these messages might be the only indication that a MEDIASRV
process stopped, specify an appropriate home terminal.
These MEDIASRV startup error messages consist only of text. They are not returned
in SPI messages, nor are they associated with an error code.
The startup message sent to the MEDIASRV process was never read by the
MEDIASRV process. The Guardian READ procedure returned a file-system error and
did not finish successfully. For descriptions of file-system errors, see the Operator
Messages Manual.
