1. The use of testing tools to simulate multiple end users concurrent testing;
The disadvantage of this test approach is that end users are often not directly connected to the database, but rather pass through one or more intermediary services, so it is not guaranteed to access the database or concurrency. Second, this test method needs to wait until the client program, the

testing a DLL file on a windows®2000 Professional machine. The physical machine runs Windows server®2008, which is called a host in Virtual Server terminology. In the background, Virtual Server runs as a Windows service on the host. The virtual machine instance running Windows Professional is called the guest machine and is managed using a web-based interface. I
Virtual server technology is used in a pilot environment to save money, time, and manpower, but the same tools, if unchecked, can lead to complex structures, waste of resources, and increased management difficulties.
Industry analysts and IT professionals say that virtualization technology relieves the physical server test environment and enables resource sharin

Oracle RAC Load Balancing enables client-initiated connections to be efficiently allocated to instances with smaller listener loads. There are two ways to achieve client load balancing, one is by configuring the client's load_balance, one by configuring the server-side Remote_listener parameters. Both approaches have advantages and disadvantages, and they are not mutually exclusive, so they can be combined in two ways to achieve more efficient load ba

By reducing the keepalivetimeout from 15 seconds to 2 seconds, you can increase the maxclients command, 19 is too small, and 128 is much better. By reducing the number of seconds that a
