SunStudio 11: unable to get collector to work

We have a pretty long web page on how to profile WebLogic. I need to find out how to get that page accessible from outside. For now, I believe I can post a launch script referred from that page:

#!/bin/sh

#@(#)collectlaunch.sh.txt 1.1 06/01/20

#

# This script is used by the WebLogic NodeManager to start up Managed servers

# on Unix systems under the control of an Admin server. The Admin

# server supplies the arguments to this script.

# The script is invoked with 4 arguments:

#Arg1: is the command line used to start up a Managed server

#Arg2: is the file to which stdout is to be redirected to

#Arg3: is the file to which stderr is to be redirected to

#Arg4: is the file into which the process id of the Managed server

#is saved.

# This script uses just one variable:

# JAVA_HOME - which is used to determine the Java version that is

# to be used to start up the WebLogic Managed server.

# set up WL_HOME, the root directory of your WebLogic installation

WL_HOME="/apps/infra/weblogic/8.1/PO/INT4/weblogic81"

# set up common environment

. "${WL_HOME}/common/bin/commEnv.sh"

# verify that JAVA_HOME points to a real Java

#? But why check for javac, as opposed to java? Only java is needed

if [ ! -f "$JAVA_HOME/bin/javac" ]; then

echo "The JDK wasn't found in directory $JAVA_HOME." > $3

exit 1 # fail if not found

fi

#last steps -- commented out here, and repeated below

# Spawn the Java

# "$JAVA_HOME/bin/java" $1 >$2 2>$3 &

#

# Save its PID, write it to the file named in the fourth argument

# PID=$!

# echo $PID > $4

#Begin customization, to enable Sun Studio Data collection on the launched server

# Set NEWARG1 to the argument to be used for invoking the JVM

# NEWARG1=`echo $1`

# At this point, massage NEWARG1 if there are any arguments to be removed

#when profiling, or extra arguments to add for profiling.

# use sed on arg1 to extract the token beginning with -Dweblogic.Name= and extract the string

#following the = which is the name of the application being launched; set APPNAME to it

APPNAME=`echo $NEWARG1 | sed 's/^.*-Dweblogic.Name=\([^ $]*\).*/\1/'`

# use sed on arg2 to remove the trailing basename to yield the directory in which

#the log files are being written and set APPDIR to it

APPDIR=`dirname $2`

# construct a name for the experiment, EXPNAME, as ${APPDIR}/${APPNAME}.mm.dd.hh.mm.ss.er

#where mm.dd... is the current time stamp

# use that EXPNAME as a -o argument to collect

EXPNAME=${APPDIR}/${APPNAME}.`date '+%m%d_01/20/06M%S'`.er

# construct a name for a script file to send SIGPROF to the process as ${APPDIR}/kill.${APPNAME}

SIG_SCRIPT=${APPDIR}/kill.${APPNAME}

# Set $COLLECTOR to command and arguments -- in this case

#Default clock profiling

#Signal-controlled pause and resume

#Archive copying for portability

#experiment name constructed above

COLLECTOR="collect -j on -y PROF -S off -A copy -o ${EXPNAME}

# Or, use APPNAME to extract COLLECTOR from a configuration file

#e.g., grep for $APPNAME.COLLECTOR, and then sed to extract

#the remainder of the line and set COLLECTOR to it

#

# Or, use APPNAME to extract components for construction of

#COLLECTOR for that application from a configuration file

#Also, could grep for additional Java arguments, etc.

# create a log of the information processed in this script

echo "arg1= " $1 > ${APPDIR}/col.log

echo "arg2= " $2 >> ${APPDIR}/col.log

echo "arg3= " $3 >> ${APPDIR}/col.log

${COLLECTOR} "${JAVA_HOME}/bin/java" ${NEWARG1} >$2 2>$3 &

# Save the PID, write it to the fourth argument (as in original script)

PID=$!

echo $PID > $4

# and write it to the collector log file

echo "PID= " $PID >> ${APPDIR}/col.log

# write a script to send SIGPROF to the process

echo "#!/bin/sh" > ${SIG_SCRIPT}

echo "kill -PROF $PID" >> ${SIG_SCRIPT}

chmod 777 ${SIG_SCRIPT}
