Integration and Acceptance Testing The purpose of integration and acceptance testing is to verify functional and performance requirements as well as the stability of an application. It can never be stressed enough that performance tests have the same importance as function tests. For all intents and purposes, an application experiencing poor performance is no worse than an application failing to fulfill its functional requirements. In both situations, the application is useless. Still, it is possible to verify the performance requirements only once they have been clearly defined.
Their purpose is to recognize irregular load patterns that pop up as well as failures. Even though these tools can monitor the whole infrastructure at once, it is important to emphasize that they monitor only individual components (for example, hosts, application servers, databases, or storage subsystems) without considering the interplay between them. As a result, it is difficult, and for complex infrastructures virtually impossible, to determine the impact on the system response time when a single component of the infrastructure supporting it experiences an anomaly.
The following are the steps carried out during the processing of a cursor: Open cursor: A memory structure for the cursor is allocated in the server-side private memory of the server process associated with the session, the user global area (UGA). Note that no SQL statement is associated with the cursor yet. Parse cursor: A SQL statement is associated with the cursor. Its parsed representation that includes the execution plan (which describes how the SQL engine will execute the SQL statement) is loaded in the shared pool, specifically, in the library cache.
