Using the new wshang.ksh version 3.1

I just downloaded the new  wshang.ksh version 3.1 and tried it. Go to  the download location.

(Note: above url is not valid any more. Please download it from My Oracle Support (MOS) site from note: Doc ID 1325651.1 - Download Location For Wshang Script - Gather Debug Data Script For Troubleshooting Oracle iPlanet Web Server or Oracle iPlanet Web Proxy Server Hangs.)

It is very easy to use.

After I downloaded and gunzipped it, I just ran it,

 APPLE:/export/home/bits/iws/misc/SUN-GDD-webserver-wshang-solaris-v3> ./wshang.ksh
./wshang.ksh[65]: date+%y%m%d%HH%MM%SS:  not found

 This script collects 3 snapshots of the following information
 at a 15 seconds interval against a web server process:
        prstat -L -a (will try 'top' on pre-Solaris 8 systems)
        pmap -x
        netstat -an
 And collections 30 seconds of:
        truss -feald -vall -wall -rall

Data will be collected to the location /tmp/wshang by default.
Data location should have enough disk space for large core files.
Would you like to specify a different directory for data?

Specify a directory:

The following is a list of web server processes:

Enter the PID of the web server process to collect data on
(Note that the correct PID for child webservd/ns-httpd process will not be listed correctly here if you have MaxProcs > 1 in your magnus.conf):

(this is already the needed worker process pid from my ptree outputs,

Then it is all done and just need to do this ,

"Please send the file /export/home/bits/iws/misc/SUN-GDD-webserver-wshang-solaris-v3/data/11111111-gdd-wshang-.tar.gz to
Sun Microsystems at
Choose cores as the destination.

NOTE : Make sure you rename the above xxx.tar.gz  so that your case SR# is part of the filename,

e.g. 71234567-customer_name-wshang-.tar.gz.

This will ensure the uploaded file will be moved to the right location for your case SR#.

Sun support engineers can then find the uploaded file easily.

New wshang.ksh version 3.0 just released


We got a new troubleshooting tool,  wshang.ksh version 3.0 just released. FYI.

You can download it at

There are some user configurable options inside, e.g.

Some notes on usage:  The customer will have to edit the script to
change a few options as needed.  These options will be made interactive
in the next release of wshang.

# The following four settings can be changed as necessary:

# Change this value to set the duration in secs between data collection


# Set the following variable to y or n to allow a gcore to be taken


# Set the following variable to y or n to allow the pkgapp script to run.

# Assumes the pkgapp script is in the same location as wshang script.


# Set the following variable with your Case Number. If no case number
has been

# opened but wish to use wshang.ksh to trap an issue, you can use your

# Name (no spaces) or all 1's.  Once you get a Sun Case number, you can

# the resulting tar file before sending to Sun.


This will be a useful tool to collect troubleshooting data for web and/or proxy server. 


to share tips and experience in Oracle products, e.g. SunONE / iPlanet Web server, Weblogic server, Web protocols, security and performance.
