IBM Technote# 1403094: Cause : unable to to respond within the default ORB request timeout due to the high load or the size of the requests.

Resolution: Increase the value of ORB timeout on WebSphere admin console >> Servers > Application servers > server_name > Container services > ORB service >> set “Request Timeout” parameter to new value. ( By default its 180 seconds, try increasing it a bit, for example try setting it to 600 seconds.)

It seems to happen often enough that I had to note this

If your in WebSphere counsole and stop your JVM but it doesn’t go down, or it partially goes down.. Open a command line on the server

If the JVM is called: server1

run this:  ps -ef|grep server1

Then find the processID and run:  kill -9 (procID)

I found an OpenSource project called Clonezilla (http://clonezilla.org/). This software does essentially the same thing as Norton Ghost, and there is also a version than can do distributed cloning (such as doing an install for a computer lab).

5.2.16. /proc/loadavg This file provides a look at the load average in regard to both the CPU and IO over time, as well as additional data used by uptime and other commands. A sample /proc/loadavg file looks similar to the following:

0.20 0.18 0.12 1/80 11206

The first three columns measure CPU and IO utilization of the last one, five, and 10 minute periods. The fourth column shows the number of currently running processes and the total number of processes. The last column displays the last process ID used.

good link to explain load:

Web container thread pool:
1.        In the administrative console click Servers > Application Servers > server_name.
2.        Near the bottom of the page, open Additional Properties, Thread Pools.
3.        Click on WebContainer.
4.        Change the Minimum Size field to whatever the Maximum is set to, probably 50.
5.        Ensure that the “Allow thread allocation ?” checkbox is not checked [or that it is set to false].
6.        Click OK and then save the configuration.

The application server will need to be restarted for the setting to take effect.

1. Click Start, click Programs, click Administrative Tools, and then click Internet Information Services.
2. Right-click a Web site that you want to enable PERL for, and then click Properties.
3. Click the Home Directory tab.
4. Click Configuration.
5. Click Add.
6. In the Executable box, type the following:
   full path to\perl.exe %s %s

Download the ActivePerl MSI file from http://www.activestate.com/

Install ActivePerl on your web server. Follow the prompts but when asked, install the program to the C:\Perl directory. (You may need to create this directory.)
