Send and Receive XML formatted text to IBM WebSphere MQ using XMS

问题 We have IBM WebSphere MQ 7.5. We have setup Queue Manager and Queues. We want to read and write XML formatted text from the queues using XMS for .net client application. I tried below code but I don't know how to read that data. Code: try { var factoryfactory = XMSFactoryFactory.GetInstance(XMSC.CT_WMQ); var connectionfactory = factoryfactory.CreateConnectionFactory(); connectionfactory.SetStringProperty(XMSC.WMQ_QUEUE_MANAGER, queueManager); connectionfactory.SetStringProperty(XMSC.WMQ_HOST

MessageListener, will it get concurrent messages

问题 I'm using XMS 7.5 client to access the IBM MQ and wanted to know one thing about MessageListener. When there are multiple messages are present on the queue, will the associated MessageListener method (i.e, ProcessNewMessage in the below code)called concurrently? OR The messages will be dispatched to the MessageListener(i.e, ProcessNewMessage in the below code) method only at a time? The code is something like below: private XMSFactoryFactory xMSFactoryFactory; private IConnectionFactory

WebSphere MQ - Changing channel definition structure using XMS.NET API

拈花ヽ惹草 提交于 2019-12-04 02:24:05
问题 I am trying to set the MQCD structure properties - specifically HeartBeatInterval using XMS.NET API. Background: I have client applications (in .NET) using XMS.NET API to read messages from WebSphere MQ. I use the ClientAcknowledge mode. If the client reads the message and does not ack it, WebSphere MQ waits for 300 seconds before timing out and makes (backout) the message available in the original queue for other clients to read the message. Task: I want to lower the timeout from 300 seconds

java -Xms -Xmx 设置java 应用程序运行的内存大小,Xms Xmx PermSize MaxPermSize 区别 版权声明:本文为博主原创文章,未经博主允许不得转载。 -Xms 和 -Xmx 是 Java 命令的一个选项,用来设置你的应用程序启动时的可用内存大小和运行时的可用的内存大小。 Xmx 是 java 的一个选项,用来设置你的应用程序能够使用的最大内存数(看好,只是你的应用程序,不是整个 jvm ) , 如果你的程序要花很大内存的话,那就需要修改缺省的设置,比如配置 tomcat 的时候,如果流量啊程序啊都很大的话就需要加大这个值了,不过有一点是要记住的,不要大得超过你的机器的内存,那样你的机器会受不了的,到时候就死翘翘了。 Xms 是另一个设置内存的参数 , 用它来设置程序初始化的时候内存栈的大小,增加这个值的话你的程序的启动性能会得到提高。不过同样有前面的限制,以及受到 Xmx 的限制。 不同的虚拟机的实现虽然千差万别,但是他们的运行模式都是一样的,只是性能有所不同罢了。 虚拟机只是一个软件实现,它是一个在内存中的机器,而我们机器上装的是 jre ,是为了生成这个 jvm 用的。通常来说,每次运行一个 application 都会生成一个 jvm ,但是也可以有多个程序在同一个 jvm 里面。 Eclipse 崩溃,错误提示: MyEclipse

I'm running the bot with the following command: java -Xms5M -Xmx10M -server -jar IrcBot.jar "/home/jbot" But top shows that actual memory reserved for java is 144m (or am I interpreting things wrong here?). 13614 jbot 17 0 144m 16m 6740 S 0.0 3.2 0:00.20 java Any ideas what can be wrong here?

java JVM虚拟机选项: Xms Xmx PermSize MaxPermSize 区别

java虽然是自动回收内存,但是应用程序,尤其服务器程序最好根据业务情况指明内存分配限制。否则可能导致应用程序宕掉。 举例说明含义: -Xms128m 表示JVM Heap(堆内存)最小尺寸128MB,初始分配 -Xmx512m 表示JVM Heap(堆内存)最大允许的尺寸256MB,按需分配。 说明:如果-Xmx不指定或者指定偏小,应用可能会导致java.lang.OutOfMemory错误,此错误来自JVM不是Throwable的,无法用try...catch捕捉。 PermSize和MaxPermSize指明虚拟机为java永久生成对象(Permanate generation)如,class对象、方法对象这些可反射(reflective)对象分配内存限制,这些内存不包括在Heap(堆内存)区之中。 -XX:PermSize=64MB 最小尺寸,初始分配 -XX:MaxPermSize=256MB 最大允许分配尺寸,按需分配 过小会导致:java.lang.OutOfMemoryError: PermGen space MaxPermSize缺省值和-server -client选项相关。 -server选项下默认MaxPermSize为64m -client选项下默认MaxPermSize为32m 经验: 1、慎用最小限制选项Xms,PermSize已节约系统资源。
