Programmatic Commands Versus Interactive
Commands
•
Size and capacity parameters (such as memory size). These parameters
determine the resources needed to run a GDSX process.
•
Attribute parameters (such as a flag specifying whether or not dynamic terminals
are supported). These parameters determine the attributes of a terminal.
•
Control parameters (such as whether or not debugging is used). These parameters
determine the internal control mechanism and can be changed at any point during
the life of the process.
To make appropriate system management decisions, you must be able to retrieve the
following information from GDSX:
•
Status messages, such as startup, open, and close messages. These messages
report a state or status change within a GDSX process.
•
Warning messages, such as “backup stopped” or a notification that a USCODE
procedure is missing. These messages report an unexpected state or status
change within a GDSX process.
•
Error messages, such as faults, checkpoint failures, and nonrecoverable errors.
These messages report that an error occurred within a GDSX process.
For information about message retrieval, see Section 5, Commands and Responses.
For information regarding GDSX messages, see the Extended General Device Support
(GDSX) Manual.
Programmatic Commands Versus Interactive
Commands
Table 1-2 shows the association between the SPI management programming
commands you send to GDSX and the Subsystem Control Facility (SCF) interactive
management commands that you can use to control and inquire about the GDS
subsystem.
