Plsql connecting Oracle requires local installation of Oracle client (download in the attachment): After downloading the file, put it in any directory, for example D:\instantclient_10_2 Modify the Tnsnames.ora file, the first line to fill in the database name to link, the 4th line to fill in the database IP, line 7th fill the SID Configure environment Variables Tns_admin D:\instantclient_10_2\, add%tns_admin% in path, this can not be less,

Objective I wanted to write a test tool before, but there was no good analytical tool, so there was no motivation to write. Recently learned to use Arthas hurriedly put the pressure test tool to fill up, Crazy Crush server performance. The existing connection pool model with Netty can save the work of maintaining the connection. Originally wrote 5 classes, sorted out the code found very simple, the base class on one. "Connection pooling" Forget who yo

Open eclipse,run--> Run configurations and enter Wsdl2java in the main class box to search, provided your project has joined Axis's jar package, Will search to Org.apache.axis.wsdl.WSDL2Java, enter parameters in the Arguments tab bar, default base directory is the current project, the parameters are as follows:src\\cfg\\test.wsdl-p com.xxx.xxx.xxx.client-tThis is the case of the WSDL file locally, if it is not a local WSDL file, but instead the URL way (for example: http://xxx:8080/xxx/xxx/xxx?w
