一、简介
环境
名称 |
版本 |
服务器操作系统 |
Centos 5.6 |
应用服务器操作系统 |
Windows 7 |
Websphere版本 |
WAS 7.0 |
数据库 |
Oracle 10g |
方向1:连接数:10-100
思路:资源àJDBCà数据源à数据源名字à连接池属性
参考操作截图,见“操作步骤”
方向2:Java虚拟机
目的:设置节点的server内存大小
参考设置堆大小:512-1024M(此处需依据实际情况做设置,有设置为:1024-2048M)
思路:应用程序服务器àserver1à进程定义àjava虚拟机
参考操作截图,见“操作步骤”

方向3:端口
说明:依据现场客户要求,默认为9080
思路:应用程序服务器àserver1à端口
参考操作截图,见“操作步骤”

方向4:启动servlet高速缓存
思路:应用程序服务器àserver1àweb容器
参考操作截图,见“操作步骤”
二、操作步骤
1、连接数的设置

2、Java虚拟机的堆大小设置

进入界面后,找到“进程定义”,点击进入:

进入后可看到堆大小设置选项,如下所示:

3、修改默认端口
当客户要求设置其它端口时,需要在此处进行配置,如下图:

点击“端口”,如下所示:

可以查看到,默认端口:9080的设置,点击进入

参考操作,如下所示:
4、启动高速缓存

三、其它设置
1、修改日志信息
设置输出记录日志信息,经过相关设置后,开发人员常会用其去找sql记录信息。
界面初览:

操作:

点击“所有组件”,进入到级别设置菜单,如下:

点击确定后,注意保存设置,如下:

类似如上设置,也可对日志文件信息进行设置,如下图提示:

2、数据源语句缓存

点击web应用服务数据源属性设置,如下:
设置区域,如下:

3、web容器线程池设置

进入server1,点击“线程池”,如下:

点击“WebContainer”设置,如下:

Time complexity measures the execution time of an algorithm relative to the size of the input. Tips for reducing the time complexity of C++ programs include: choosing appropriate containers (such as vector, list) to optimize data storage and management. Utilize efficient algorithms such as quick sort to reduce computation time. Eliminate multiple operations to reduce double counting. Use conditional branches to avoid unnecessary calculations. Optimize linear search by using faster algorithms such as binary search.
