Hi !

----

Long long ago there was an unix-startup/shutdown script...

... and here comes an update for it :-)

The script is configured for Solaris 7 but should work on Solaris >=
2.5.1 and Linux, too.
The script requires some modifications (admin user+password for
"jigkill", CLASSPATH and path to server config) to run on your site.

----

Bye,
Roland

#######################################################
# version history
# V1.15 (05.09.2000): - Fixed various flaws in function handling for Solaris /sbin/sh
#                     - Added extra "sleep" after sending SIGTERM to give signal handler in jigsaw more time
#                     - Increased limit of max. open files per process to 1000
# V1.14 (03.03.2000): - Now uses test -d /proc/<pid> to test if process exists or not
#                     - Moved check into a seperate function "pexists"
# V1.13 (24.01.2000): - Replaced JSDK 2.1 with "tomcat" (JSP 1.1 and JSDK 2.2)
# V1.12 (27.09.1999): - Removed check for single user dirs at jigsaw startup, 
#                       instead a single test is made if the automounter is running.
# V1.11 (05.09.1999): - Improved checking if automountd can reach user directries or not.
# V1.10 (12.08.1999): - Added JIGROOT config variable which allows that jigsaw's root can be anywhere.
#                       Suggested by John E. Conlon (jconlon@verticon.com). Thanks !
# V1.9  (11.08.1999): - removed -host option at startup. It seems that jigsaw 2.0.3 no longer requires this option...
# V1.8  (26.07.1999): - fixed the longstandig (silly!) bug that "ps -ef | grep bla-bla" returns the "grep" line
#                     - "grep" replaced by "fgrep" - smaller, faster...
#                     - reduced the "start" sleep value back to 5 sec...
# V1.7  (29.05.1999): - Changed CLASSPATH for JAVA Project-X Release 2
# V1.6  (12.05.1999): - stop now only starts jigkill if there's a jigsaw-server process running
# V1.5  (07.05.1999): - start: increased the delay from 10 to 20 sec after jigsaw has been invoked because 
#                       some msgs are "eaten" by dtlogin/xdm
# V1.4  (03.05.1999): - added "save" option to save servers
#                     - "stop" option now waits until the "jigkill" background process returns
#                     - fixed delay in stop option (was "sleep 8" instead of "sleep 5"; 
#                       bug introduced in V1.2)
#                     - fixed startup delay (should be 10 sec to see jigsaw's startup messages on console)
# V1.3  (28.04.1999): - changed CLASSPATH for new servlet archive /usr/local/java/jsdk2.1/servlet.jar
#                     - added SIGKILL shutdown method to force a "shutdown" of jigsaw service if SIGTERM 
#                       did not work
#                     - added "restart_server" switch to make "stop" + "start" in one step.
#                       (I did not use the name "restart" because this may be reserved by another /etc/init.d/ 
#                       script functionality...)
# V1.2              : - added "sleep 5" at startup to see servers startup messages before xdm/dtlogin hides 
#                       this info...
# V1.1              : - initial release
