HP DIAGNOSTICS

Overview
Identifying and correcting availability and performance problems can be costly, time consuming and risky. IT organizations spend more time identifying an owner than resolving the problem.
HP Diagnostics helps to improve application availability and performance in pre-production and production environments. HP’s diagnostics software is used to drill down from the end user into application components and cross platform service calls to resolve the toughest problems. This includes slow services, methods, SQL, out of memory errors, threading problems and more.

Performing Manual Correlation with Dynamic Boundaries in LR

What is Correlation: It is a Process to handle dynamic values in our Script. Here the dynamic value is replaced by a variable which we assign or capture from the server response.

Ways to do correlation: There are two ways to do this Correlation.

They are as follows:

• Auto-Correlation: The Correlation Engine in LR Package captures the value and replaces it with another value
• Manual Correlation: Understanding of the Script and its response is highly needed to do this. It is bit complex to do Manual Correlation sometimes but this is always the preferred method to handle Dynamic Values in our Script

Usually the Manual Correlation is done by capturing the dynamic value which is present in between the Static left and right Boundaries.

Objective: The intention of this article is that to give a method which will be useful when we wanted to capture and handle Dynamic Values when even the Left and right Boundaries are also dynamic.

HP Ajax TruClient – Overview with Tips and Tricks

Overview

• In LoadRunner 11.5, TruClient for Internet Explorer has been introduced. It is now possible to use TruClient on IE-only web applications.

Note: This still supports only HTML + JavaScript websites. It does not support ActiveX objects or Flash or Java Applets, etc.

• TruClient IE was developed as an add-in for IE 9, so it will not work on earlier versions of IE. This version of IE was the first version to expose enough of the DOM to be usable by a TruClient-style Vusers. Note that your web application must support IE9 in “standard mode”.
• Some features have also been added to TruClient Firefox. These include:
  • The ability to specify think time
  • The ability to set HTTP headers
  • URL filters
  • Event handlers, which can automatically handle intermittent pop-up windows, etc.

• Web page breakdown graphs have been added to TruClient (visible in LoadRunner Analysis). Previously they were only available for standard web Vusers.

XML Optimization through custom Properties

1. Problem Statement:

I am creating a XML file as an output . If my source is empty, is there a way to  avoid the creation of an empty XML file?

Sample output Data with source data :

Case 1 : Empty Source – Creation of Minimal XML file

We have to set the following properties of an XML Target at session level under the Mapping tab.

Null Content Representation – “No Tag”

Empty String Content Representation – “No Tag”

Null Attribute Representation – “No Attribute”

Empty String Attribute Representation – “No attribute”

Advanced Replication Setup for High availability and Performance

In my personal opinion, Oracle leads the market in Directory Product offerings (LDAP Directories). Starting from Oracle Internet Directory (OID), to the latest Oracle Unified Directory (OUD), Oracle definitely provides variety of LDAP Directory related products for integration.

With increasing demand for mobile computing and cloud computing offering, there is a need to standardize LDAP Deployments for Identification, Authentication and (sometimes) Authorization (IAA) services. With a highly scalable, highly performing, highly available, highly stable and highly secure LDAP Directory, these IAA services will be easier to integrate with applications in the cloud or for the mobile applications.
