What I do is:
1. Download the log4jdbc4-1.2alpha2.jar, and put into $PE_HOME/jars
2. Download from SL4J the compress file: slf4j-1.5.8.tar.gz. Extract slf4j-api-1.5.8.jar and slf4j-simple-1.5.8.jar from the compress file, and put into $PE_HOME/jars
3. Modify $PE_HOME/conf/pe_dic.props, remark the old value and change the line:

#pe_dic.Url=jdbc:oracle:thin:@myoraclemachine:1521:PHDIC
pe_dic.Url=jdbc:log4jdbc:oracle:thin:@myoraclemachine:1521:PHDIC
#pe_dic.Driver=oracle.jdbc.driver.OracleDriver
pe_dic.Driver=net.sf.log4jdbc.DriverSpy

You’ll need to check your $PE_HOME/logs/pe_dic-server.log, to see the additional jdbc log messages.
Below is the snippet of the log file:

The problem happen when we try to install as a user which its home directory is not mounted. We tried to set the HOME to other directory by setting up HOME environment variable. But, we got:
No module find error

Then we try to debug the installation by:
sh -x setup.bin
It come back with a lot of debug messages, and at the end we will see a line with:
CLASSPATH=/tmp/install.829388/jar/...
exec /tmp/install.829388/jre/bin/java ....

What we did is to manipulate the user home by
$export CLASSPATH=/tmp/install.829388/jar/...
/tmp/install.829388/jre/bin/java -Duser.home=/tmp/tmpdir ...
This way, we will force the installer to use different HOME directory

The work around is to set IATEMPDIR environment to location that has sufficient space
$ export IATEMPDIR=/glb/apps/3rdparty_test/tmp

JConsole remotely monitors JMX-enable Java Apps

To enable JMX in PowerHub add lines below to $PE_HOME/bin/runServer:
-Dcom.sun.management.jmxremote \
-Dcom.sun.management.jmxremote.port=8024 \
-Dcom.sun.management.jmxremote.authenticate=true \
-Dcom.sun.management.jmxremote.ssl=false \

Notice:
1. JConsole is part of JDK default installation
2. “-Dcom.sun.management.jmxremote” is minimum parameter to enable JMX for local console. But this is not advisable.
3. Remote connect of JConsole can be achieve by setting the other three parameters
4. Remote connect use port. Each Java Application should be started with a separate port. e.g: 8001, 8002, 8003,…
