[DAEMON] Problems with JSVC and Solaris 9

[Administracion de sistemas web <ad...@merlot.tel.uva.es>]

Hello, this is my first post in this list. I'm not an expert so I
apologize for any mistake in the description of the problem.

Scenario
-> Hardware: SunFire V210 (sparc)
-> OS: Solaris 9
-> Common daemons version: I'm using the JSVC source code included with
Tomcat 5.0.16 release.


Main problem:
I compile jsvc source code following the indications in 
http://jakarta.apache.org/tomcat/tomcat-5.0-doc/setup.html without errors.

I run jsvc with the following command $CATALINA_HOME/bin/jsvc -user tomcat
-Djava.endorsed.dirs=$CATALINA_HOME/common/endorsed -cp
$CATALINA_HOME/bin/bootstrap.jar -outfile /export/logs/tomcat/catalina.out
-errfile /export/logs/tomcat/catalina.err -pidfile
$CATALINA_HOME/bin/jsvc.pid org.apache.catalina.startup.Bootstrap

The Tomcat server started and the user change is made. No problems here.
The problem is in the shoutdown. When I kill the process with the command
kill #process_number_in_jsvc.pid the server stops but if I have a look to
the errfile (catalina.err) I see that in the last line "jsvc error:
Service
exit with a return value of 143". And the most important thing is that
tomcat didn't stop correctly. When I have a look to tomcat's log there are
no references to the shutdown, the last line is "INFO: Server startup in
8109 ms" (usually when you stop Tomcat without using JSVC there are
always some lines in the log describing the shtdown process).

I try to track the program with debug mode. I also add a print line after
waitpid() in the parent process to know the status value before processing
it with wstat macros. Here it is, I hope it can be helpful:

$CATALINA_HOME/bin/jsvc -verbose -debug -jvm server -home /usr/local/java
-user tomcat -Djava.endorsed.dirs=$CATALINA_HOME/common/endorsed -cp
$CATALINA_HOME/bin/bootstrap.jar -outfile /export/logs/tomcat/catalina.out
-errfile /export/logs/tomcat/catalina.err -pidfile
$CATALINA_HOME/bin/jsvc.pid org.apache.catalina.startup.Bootstrap

Other problems:

I have found also other minor problems:

-> I have the same core dump problem with jsvc -help that was describe in
http://www.mail-archive.com/commons-user@jakarta.apache.org/msg05127.html
I solve it creating a jvm.cfg file with this content:

root@merlotnew:/usr/local/java/jre/lib# more jvm.cfg
#
# @(#)jvm.cfg   1.10 00/08/01
#
# Copyright 1999 by Sun Microsystems, Inc.,
# 901 San Antonio Road, Palo Alto, California, 94303, U.S.A.
# All rights reserved.
#
# List of JVMs that can be used as the first option to java, javac, etc.
# Order is important -- first in this list is the default JVM.
#
-client
-hotspot
-server
-classic



The good point is that 1.3 and 1.4 Jvm.cfg files are in different places
so you can have both at the same time.


-> I get also a core dump is I use the debug option alone. Example, this
command fails:

root@merlotnew:/usr/local/tomcat/bin# $CATALINA_HOME/bin/jsvc -debug -user
tomcat -Djava.endorsed.dirs=$CATALINA_HOME/common/endorsed -cp
$CATALINA_HOME/bin/bootstrap.jar -outfile /export/logs/tomcat/catalina.out
-errfile /export/logs/tomcat/catalina.err -pidfile
$CATALINA_HOME/bin/jsvc.pid org.apache.catalina.startup.Bootstrap

jsvc debug: | JVM Name:        "Error de segmentaci�n (se ha creado un

The last line means "Segmentation fault, core dumped in Spanish. If I use
the -jvm and the -home options I don't get that core dump. I think there
is some probblem in the arguments parssing, perhaps in the optional()
function.



Sorry for this long e-mail, but I think that the debug information was
necessary.
