exitNode - "gracefully" terminate SIAM node service

exitNode nodeHost

The exitNode utility "gracefully" shuts down each SIAM instrument service on the specified node (effectively executing shutdownPort for each service), switches off power to all instrument ports, and then terminates the SIAM node service. E.g., the following shuts down the instrument and node services on "surface":
 

% exitNode surface

Note that delays will occur while each instrument service is being terminated, depending on how the specific instrument service shuts down its device. If for some reason these delays are excessive, it is possible to use killj9 to immediately terminate the node application. Note however that killj9 does not result in graceful instrument shutdown or power shutoff.

This utility may be run on the same host as the node, or on any networked host from which the node host is accessible. If run on the node's host, then nodeHost can be specified as "localhost" or simply "loc".

ENVIRONMENT

The following environment variables must be set:

• JAVA_HOME - location of Java installation, e.g. /j9 or /opt/java/jdk1.3.1
• JAVA - name of the JVM. E.g. on a Sidearm, JAVA should be set to j9. On a workstation with Sun's Java installed, JAVA could be set to java.
• SIAM_HOME - top of the SIAM directory tree
• SIAM_CLASSPATH - on a Sidearm, SIAM_CLASSPATH should be set to $JAVA_HOME/lib/jclMax/classes.zip:$JAVA_HOME/lib/prsnlmot.jar:$JAVA_HOME/lib/RXTXcomm.jar:$SIAM_HOME/classes.  On X86 system, SIAM_CLASSPATH should be set to $SIAM_HOME/classes
