如何用java 监控websphere是否正常运行
告诉你一个简单的办法，你先看看你websphere的端口是多少，然后写几行代码，也去偿试监听这个端口，因为这个端口已经被占用了，会报异常，这时候说明websphere是正常的，只要你的这个小程序端口监听成功了，你就可以理解为websphere挂了
如何在java中使用WebSphere MQ
websphere mq : 用于传输信息 具有跨平台的功能。
1 安装websphere mq 并启动
2 websphere mq 建立 queue Manager (如：MQSI_SAMPLE_QM)
3 建立queue 类型选择 Local类型 的 （如lq ）
3 建立channels 类型选择Server Connection （如BridgeChannel）
java 代码如下：
package test.mq;
import com.ibm.mq.*;
/*
* 成功的访问mq 的java 类
*/
public class FirstMqTest {
// public static void main(String[] args[]){
// FirstMqTest first = new FirstMqTest();
// first.test();
// }
public static void main(String args[]){
FirstMqTest first = new FirstMqTest();
first.test();
}
public void test(){
String qManager = "MQSI_SAMPLE_QM"; //QueueManager name
String qName = "lq";//Queue Name
try {
//configure connection parameters
MQEnvironment.hostname="172.16.17.123";//MQ Server name or IP
//MQEnvironment.port=1414;//listenr port
MQEnvironment.channel="BridgeChannel";//Server-Connection Channel
MQEnvironment.CCSID =1381;
// Create a connection to the QueueManager
System.out.println("Connecting to queue manager: "+qManager);
MQQueueManager qMgr = new MQQueueManager(qManager);
// Set up the options on the queue we wish to open
int openOptions = MQC.MQOO_INPUT_AS_Q_DEF | MQC.MQOO_OUTPUT;
// Now specify the queue that we wish to open and the open options
System.out.println("Accessing queue: "+qName);
MQQueue queue = qMgr.accessQueue(qName, openOptions);
// Define a simple WebSphere MQ Message ...
MQMessage msg = new MQMessage();
// ... and write some text in UTF8 format
msg.writeUTF("Hello, World!");
// Specify the default put message options
MQPutMessageOptions pmo = new MQPutMessageOptions();
// Put the message to the queue
System.out.println("Sending a message...");
/*
* 在此测试一下 mq 的传输次列
*
*/
for(int j=0;j 5;j++){
String str ="test11111111111";
str = str+j;
msg.writeUTF(str);
queue.put(msg, pmo);
}
queue.put(msg, pmo);
// Now get the message back again. First define a WebSphere MQ message
// to receive the data
MQMessage rcvMessage = new MQMessage();
// Specify default get message options
MQGetMessageOptions gmo = new MQGetMessageOptions();
// Get the message off the queue.
System.out.println("...and getting the message back again");
queue.get(rcvMessage, gmo);
// And display the message text...
String msgText = rcvMessage.readUTF();
System.out.println("The message is: " + msgText);
// Close the queue
System.out.println("Closing the queue");
queue.close();
// Disconnect from the QueueManager
System.out.println("Disconnecting from the Queue Manager");
qMgr.disconnect();
System.out.println("Done!");
}
catch (MQException ex) {
System.out.println("A WebSphere MQ Error occured : Completion Code "
+ ex.completionCode + " Reason Code " + ex.reasonCode);
}
catch (java.io.IOException ex) {
System.out.println("An IOException occured whilst writing to the message buffer: "
+ ex);
}
}
}
