Application development risk has never been higher. Deployment of applications has become risky. Applications impact how internal business gets done, how customers transact and how companies care for their customers. Customer facing, distributed applications present the greatest challenge. These applications prevent you from controlling one the most important variables of system performance, the number of users. More components, platforms and applications than ever before are required to work together in these business systems. Finding problems late in the development cycle is costly and damaging.
Test your application with QACenter Performance Edition to determine production readiness and you’ll know whether or not you’re ready to go live. Our tools help you expose and resolve issues that would otherwise impact application scalability and performance and the ultimate satisfaction of your customers and business partners.
Our solution helps you conduct realistic, in-depth and repeatable performance testing on applications throughout the enterprise. With a powerful combination of load testing and resource utilization tools, you will not only identify performance problems quickly but also have the critical information needed to resolve those problems, before customers and business partners are impacted.
Improve the scalability and availability of your applications with QACenter Performance Edition.
Using QALoad, you can simulate the load generated by hundreds or thousands of users on your application—without requiring the involvement of the end users or their equipment. You can easily repeat load tests with varied system configurations to achieve optimum performance.
From the Conductor module in QALoad, you set up a load testing scenario to control the conditions for the test, create the virtual users you need to simulate the load, initiate and monitor test and report the results. A Player module simulates the roles of users performing multiple functions using testing scripts that represent your application
QALoad’s Script Development Workbench provides customized modules that facilitate the development of testing scripts. These modules, called EasyScripts, allow testers to record the traffic an application generates and convert it into a testing script.
The resulting scripts directly reflect the actual traffic generated by the application and measure the time taken to perform these transactions to ensure that the system under test will perform to specifications under load.
During each QALoad test session, performance statistics can be viewed online. QALoad enables testers to insert checkpoints into scripts to identify and review specific areas of system performance for a test. QALoad displays test results in a variety of reports, graphs and charts.
The data from a testing session can also be automatically exported to office automation packages or custom analysis programs for further review.
Compuware’s ServerVantage provides an in-depth view of your application by monitoring its operating system, database and network components, as well as the application itself. QALoad’s integration with ServerVantage allows you to generate a realistic load on your system while monitoring it for resource utilization problems. Application response time and resource utilization data from a load test can be accessed from the QALoad Conductor, allowing you to quickly identify and resolve application bottlenecks.

File-AID/CS provides data management for objects created in eXtensible Markup Language (XML) for complex information-sharing between B2B web applications. File-AID/CS gives users the XML edge, allowing them to use XML technology to bridge the gap between web-based applications.
With File-AID/CS, you can verify the reliability of your B2B application and the XML data it uses by generating XML data for test purposes and validating the accuracy of the results. With its simple Graphical User Interface, developers and can easily transform complex relational databases into accurate streams of XML data.
File-AID's Compare facility discovers, displays and reports differences between two XML files or between an XML data stream and a relational database table. A color-coded comparison report, viewable either online or in print, identifies the exact XML data that has been inserted, deleted or changed.
File-AID/CS allows developers to populate test tables with subsets of data that accurately reflect production relationships. You can quickly define the criteria for copying subsets and extract the precise amount of data required to satisfy the relationships defined between the tables. You need copy only the rows required to satisfy the selected relationships, customizing data for specific testing requirements. You can also save, modify and reuse all extract and load criteria, making it easy to repeat the process each time you must restore the test database. File-AID/CS helps load a set of related tables into Oracle, Sybase, Informix, Microsoft SQL Server or DB2 UDB, regardless of the database management system where the data originated.
Using File-AID/CS in combination with File-AID/RDX on the mainframe, you can create test data by easily selecting synchronized subsets of DB2 data and loading them into your target client/server databases. File-AID/CS automatically generates the DDL and runs the necessary utilities to create the target tables, keys and indexes. It also loads the data in the proper order to maintain the original data relationships and dependencies.
File-AID/CS automatically transforms data in the major client/server databases, eliminating the need to write one-time programs. It manipulates, converts and transforms data to create specific test cases.
You define transformation criteria for each column/field through a graphical interface. You can use data structures as templates for identifying the columns/fields containing the data values. For example, use table definitions, DDL or COBOL record layouts directly as the templates. You can also define selection criteria to age only a subset of a table/file.
Once you have created your test data and run a test case of your application, you need to be able to view and analyze the results. You can do this manually, but scanning pages of "before" and "after" data can be both tedious and inaccurate. File-AID/CS automates this comparison for you.
File-AID/CS gives you an efficient, accurate way to compare the differences in Oracle, Microsoft SQL Server, DB2 UDB, Sybase, Informix and many other 32-bit ODBC-compliant databases. It can also compare ASCII text and report files.
File-AID/CS enables you to:
The File-AID/CS report includes rows that have been inserted, deleted or changed. In addition, File-AID/CS can group the comparisons you have created and run them in batch. If you want to examine specific portions of the tables yourself, use File-AID/CS to browse them. With File-AID/CS's query facility, you can easily select subsets of data to view. After retrieving the data, you can further customize the display to view only the data you need and in the order you need it. In addition, File-AID/CS can automatically find any invalid data in UNIX files so that you don't have to search for it manually. It can also display multiple tables simultaneously from the same or different databases.
File-AID/CS enables you to create test data by copying a subset from an existing database or file. File-AID/CS can convert, copy and reformat a range of data types and formats. It can be used to copy a subset of data between two like file or database or easily create test data.
For example, if you need to access production data stored in Oracle or DB2 UDB, File-AID/CS can subset that data based on your selection criteria then load it into any if the other supported databases. You can also use File-AID/CS to convert data between numerous data types and relational databases; for example, between XMLand Oracle, or Sybase and Access.
Using a graphical interface, File-AID/CS enables you to view your source and target data structures side by side, drag and drop data fields between them and define any modifications or calculations required for these fields. It also converts EBCDIC to ASCII and performs intelligent conversions of packed fields, if necessary. You can also save these conversion criteria to restore your data at any time.
After having copied data into your test environment using File-AID/CS, you can further refine the data to introduce new test conditions.
Using File-AID/CS's spreadsheet interface, you can access Oracle, Sybase, Informix, Microsoft SQL Server and DB2 UDB data from anywhere in the enterprise. You can also access UNIX files through the same interface and use COBOL record layouts as templates. These editing and browsing capabilities allow you to make changes easily and accurately.
Sometimes there is no existing data within your enterprise to use as a starting point for your testing needs. File-AID/CS can automatically generate test data, based on the parameters you define for generating the columns and rows. For example, it can generate random numbers, create strings in specific formats, create numbers sequentially and ensure that values fall within certain limits. This saves you the time it would take to enter the data manually.
Once you have run a test case of your application, you need to reset your test data to its baseline values. The File-AID/CS products help automate this process several ways: if your data has only a few changes, you can use File-AID/CS's editing or global search/replace features to restore the test data to its original values; if your application changed a lot of data, you may prefer to recreate the original test tables from the master test database. The stored conversion and load criteria make it easy to refresh the test data automatically.
