playback screenAdd the CLAPPR plugin after the playback screen　　CLAPPR Architecture:Guided by component-based software engineering theory, the Ribeiro team listed the CLAPPR three main plugins: 1. Playback PluginUsed to play a video resource. CLAPPR will traverse all the playback plugins until they find the plugin that will play correctly.2. Container plug-inEach playback is associated with a container. In most cases, a container matches a resource playback and is instantiated.

also said that the port number is configured correctly firewall interception may also cause this problem, Then just go to the firewall in the "exception" to add your database to use the port number on it, if the installation of firewall software is the same reason, add an exception to the port. Finish the above changes first use Sqlplus to try, if you can log in then on the right, if you can not login, then you need to open the database

and sensors. And the performance of Ssio is better than Sio, and it supports 4 kinds of control modes, polling mode, auto-control mode, concurrency mode and singleton mode.When using Sio and Ssio two-time forms, you do not need to care about the scheduling of devices, Io, and control modes, just inherit the interface development device driver and set the corresponding parameters. In addition, Sio and Ssio can be used as the core communication components of the configuration software. E

Currently, well-known concurrent performance testing tools include rational robot, qaload, LoadRunner, and Microsoft was. Among them, qaload, LoadRunner, and rational robot are all good commercial testing tools (expensive). Microsoft's was is a free testing tool that is easy to use, however, because the recorded test script cannot be displayed or edited, its controllability and graphical test results are weak, which causes some limitations. Opensta is a free performance testing tool dedicated t
