1 压力测试

1.1环境

Weblogic版本:9.2  

数据库版本：informix:11.5

JDK版本: jrmc-3.1.0-1.5.0

1.2 压力测试问题现象以及分析

1.2.1整体监控

  从晚上7：30到晚上10点，混发压力测试。压力测试间多次取thread dump并分析，发现大量的thread 被堵塞。从应用的日志文件中分析，发现有执行超时的线程。

1.2.2异常分析

1） 应用中有执行时间过长的线程。该线程与数据库的操作有关。建议开发工程师和数据库工程师参与分析。

2 建议

      所有系统中的应用都部署在域的admin server中，建议新建一个被管服务，把应用部署在被管服务中，admin server只做管理用。

驱动类名：com.informix.jdbc.IfxDriver

链接URL：jdbc:informix-sqli://hostname:1526/dbname:INFORMIXSERVER=informixservername;user=username;password=password

获得方式：Class.forName ("com.informix.jdbc.IfxDriver");

con=DriverManager.getConnection("jdbc:informix-sqli://hostname:
port:informixserver=servername;user=username;password=realpassword");
