Interpreting Console and EMS Messages

Messages generated by GDSX can be classified according to severity:

Where Messages Are Displayed

GDSX can generate console messages to the home terminal and EMS messages to

an EMS display terminal. These terminals can be configured to be the same device or

different devices.

Home Terminal

At process initialization time, all messages from TSCODE are sent to the home

terminal, because the monitor task, which handles messages sent to EMS, is not yet

active. To ensure that all messages are seen, you can change the home terminal to a

paused terminal. For example, the following RUN command changes the home

terminal to device $TF2.#F22:

> RUN GDSE /NAME $GDSX, NOWAIT, TERM $TF2.#F22/

Make sure you pause such a terminal.

Status messages Report a state change within a GDSX process. Some examples

of status messages are startup, open, and close messages.

Warning

messages

Report an unexpected state change within a GDSX process.

An example is a message reporting that the backup stopped.

Error messages Report that an error occurred within a GDSX process. Two

examples of conditions that cause the generation of error

messages are a checkpoint failure and a memory pool error.
