TERM Commands
Considerations
The PATHMON process returns an error if any of the following conditions apply:
A FREEZE command has not been issued against the server.
The specified TERM object is not communicating with the specified server.
The TERM object's STOP-MODE special register is zero, signifying that the
TERM object is not preventing the server from being frozen.
The PATHMON process also returns an error if the server is already frozen. Note
that this can occur after the first in a loop of FREEZESTATUS SCTERM
commands because of the following sequence of events:
1. The first TERM object is stopping the freeze; status is reported on the first
TERM object.
2. The first TERM object completes; the server class freezes.
3. The second FREEZESTATUS command arrives at the server and receives an
error.
