Vncviewer clipboard operations like copy/cut+paste suddenly stops on linux

Many times you must have observed that clipboard operations like copy/cut and paste suddenly stops workings with the vncviewer. The main reason for this there is a program called as vncconfig responsible for these clipboard transfers. Some times the program may get closed because of some bug in vnc or some other reasons like you closed that window.

To get those clipboard operations back you need to run the program "vncconfig &".

After this your clipboard actions should work fine with out any problems.

How to Use Jmeter to do the LDAP/OID Load Testing

This summary is not available. Please click here to view the post.

How to use Jmeter to load test Portal Application

1. Download the latest Jmeter version from http://jakarta.apache.org/jmeter/

2. Set the JDK 1.5 or JDK 1.6 in your path and run jmeter.bat batch file

3. Create a Thread Group with the following values

Set the number of Threads to 50 and the Loop Count to 10. This will send 500 requests to the server

 

4. Under the ThreadGroup create HTTP Cookie Manager with the following values

The CookieManager is required to pass the cookie values across the different page requests. Otherwise Jmeter ignores the cookie value.

In the cookie manager select the Check Bog Clear Cookies each iteration and set the Cookie Policy to Default.

5. Under the Thread group create a Loop Controller

Right Click on the Thread Group and Add Logical Controller –> Loop Controller

6. Under the Loop Controller Add Sampler –> HTTP Request HTTP Client

Set the Server Name as say xxx.xxx.oracle.com and Port as 7784 enter the Path as /portal/page?_pageid=33,1&_dad=portal&_schema=PORTAL&_mode=16 Select the CheckBox “Follow Redirects”

7. Under HTTP Request HTTP Client add the HTTP Authorization Manager

Add the Portal username and password in this example I used orcladmin and welcome1.

8. Add another Portal Page for testing

Under the Loop Controller Add Sampler –> HTTP Request HTTP Client

9. Add another SSO Protected  Page for testing

Under the Loop Controller Add Sampler –> HTTP Request HTTP Client

Use the following values shown below

10. This is how the JMeter project looks like after doing the above steps

11. Now run the Jmeter project by Pressing  Control+R or the Menu option Control+R

12. Check the access_log file for the requests from the Jmeter load test
