Startup Errors

An SCP process generates the following 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, the SCP process calls the Guardian

ABEND or PROCESS_STOP_ procedure.

The SCP process writes the message to its home terminal. If a home terminal was not

specified in the RUN command, the default is the terminal that is 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 SCP process can 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 an SCP process

has stopped, you should specify an appropriate home terminal.

These SCP 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 SCP process was never read by the SCP process. The

Guardian READ procedure returned a file-system error and did not finish successfully.

The SCP process could not obtain its own ID.

parameter-number

indicates which run option is invalid.

A run option specified in a RUN command or in a startup message is invalid. Run

options are numbered in the order that they appear in the RUN command or startup

message. For example, if the first run-option parameter specified in a RUN command is

BACKUPCPU and if this parameter has an invalid value, parameter-number in the

error text would be 1.

The SCP process was not started with a process name.
