The article will provide a user with information on Middleware Management with Oracle Enterprise Manager Grid control. It will cover synthetic transaction and managing Enterprise Manager.
Synthetic transaction
There are times when all of the performance indicators are within acceptable ranges, but users still complain for about application performance. In order to troubleshoot issues, the system administrators can log in to the application to try to simulate what the real users do. Users wil note that sometimes such problems are related to some specific geographic regions only. An example will make this clear. The customers in Europe cannot check out the shopping cart but customers in other countries are fine.
In order to monitor such issues a user can record typical user actions and then repeat those instructions from different geographical regions. The Enterprise Manager provides a framework for such support where typical user behavior can be recorded and repeated from various geographical locations. A user can record the web transaction for checking out of the shopping cart and can repeat this synthetic transaction from various locations. A user can also use the web transactions to check the availability for web applications. Enterprise Manager provides other mechanisms to check the availability of other resources. Fore example a user can use TNSPING to check the availability of a database.
Managing Enterprise Manager
Enterprise Manager has a multi-tiered architecture; with the presentation layer on a J2EE server and content that is presented in HTML format. The Enterprise Manager console can be accessed through a browser that the system administrator can access remotely. Enterprise Manager is certified for all major browsers like Internet Explorer, Firefox, Netscape, Mozilla, etc.
