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.

http://www.sun.com/bigadmin/jsp/descFile.jsp?url=descAll/sun_gdd_wshang_vers

(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:
        pstack
        pfiles
        prstat -L -a (will try 'top' on pre-Solaris 8 systems)
        pflags
        pmap -x
        pldd
        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?
(y/n)


Specify a directory:
/export/home/bits/iws/misc/SUN-GDD-webserver-wshang-solaris-v3/data


The following is a list of web server processes:

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 https://supportfiles.sun.com/upload
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

Hi,


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


You can download it at


http://www.sun.com/bigadmin/jsp/descFile.jsp?url=descAll/sun_gdd_wshang_vers


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
rounds

DURATION=15


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

CORECHOICE=y


# 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.

PKGAPP=y


# 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
Company

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

# the resulting tar file before sending to Sun.

CASENUMBER=11111111


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

Pkgapp 3.0 for Solaris Available now !

I just know this, so share here,


Pkgapp 3.0 for Solaris Available!


 This is a very useful tool to collect the data for troubleshooting, see more at web GDD , e.g.

Data collection for Sun Java Web server issues ?

If you hit some issues in Sun Java Web server, then you will likely try to collect some data for more troubleshooting.


One url  that  shows the data collection :


http://docs.sun.com/app/docs/doc/820-2483/gebaq?a=view



"



1.5 Types of Web Server Debug Data


This section describes the various kinds of debug data that you need
to provide to the Sun Support Center. The procedure to obtain debug data based
on the kind of problem you are experiencing is described in-detail.


This section contains the following topics:




"


You can see different types of issues and their appropriate data collection.


The data will be helpful if you open a support case with Sun, or try to do any problem isolation by yourself. 


There are other GDD docs for other products.


Hope this can help you next time when you try to collect data for problem isolation and troubleshooting.
