NRJE Shutdown
NRJE Shutdown
Two ways to shut down NRJE using MPE commands exist:
• Stop NRJE using an NRJECONTROL STOP or NRJECONTROL HALT
command from MPE.
• Issue an SNACONTROL STOP command from MPE. This shuts down
the SNA link and NRJE.
A STOPWS issued from within NRJE has the same effect as an
NRJECONTROL STOP. A HALT issued from within NRJE has the same
effect as an NRJECONTROL HALT. NRJECONTROL HALT and NRJECONTROL
STOP as well as the and HALT commands are described in the SNA
NRJE Node Manager’s Guide. SNACONTROL STOP is described in the
SNA Link Services Reference Manual or the SNA Link/XL Node
Manager’s Guide.
Upon terminating communication with the host, NRJE will set
NRJEJCW in the job stream to indicate the reason for the termination.
This JCW can be used to determine whether to attempt to restart
NRJE in the job stream.
These JCW values may vary depending on the version of the SNA link
product installed on the system.
In general, all other values set upon termination are a result of a
potential error condition encountered.
