How to get “saveqmgr -s” function using “dmpmqcfg” in IBM MQ

由 烂漫一生 提交于 2019-12-11 13:31:32
问题 I am used to dumping objects from a queue manager without system objects. But now I have to use dmpmqcfg and I cant find a flag to remove those system objects from output. MQ version is 7.5.0.1 Command I use now : dmpmqcfg -m SMQ -t all -x object Possible flags : c:\> dmpmqcfg -h Usage: dmpmqcfg [-m QMgrName] [-n ObjName] [-t ObjType] [-x ExportType] [-o Format] [-a] [-z] [-s MsgSeqNo] [-q RplQName] [-r RmtQMgrName] [-c default|-c DEFINE CHANNEL..] -m Queue manager name. -n Object name or a

Certificate Label when fetching from Windows Cert Store for .Net MQ Client

由 落花浮王杯 提交于 2019-12-11 10:05:20
问题 I have set the KeyStore to *User to get the certificate from the windows certificate store.The Mq Client application is trying to find the certificate using the label name as shown in the log from the client Trace. I tried setting the CertificateLabel from the client.ini and code but it is not overriding the value. How should i change that? Even if i can override how can i change the label of the certificate which i directly imported into my certificate store? Please Help 000001B6 12:23:39

Lifecycle of MQ Connection in JSF - Connection Closed

由 不问归期 提交于 2019-12-11 06:00:40
问题 I use JSF 2 an WebSphere MQ for Messaging (JMS). I want to know what's the best practice to open / close the QueueConnection? Should I use for each client session one connection and open it on (post-)construction and close it on (pre-) destruction like here? Or are there better ways to handle the connection? E.g. "Open EntityManager in View" Pattern for JDBC/JPA? 回答1: Avoid creating a new connection for each getMessage() invocation. Create one connection at construct time, save it as an

Routing messages in RabbitMQ topic exchange that do NOT match a pattern

由 二次信任 提交于 2019-12-10 18:17:20
问题 Two queues are bound to a topic exchange with the following routing keys: Queue A, bound with routing key pattern match *.foo Queue B, bound with routing key pattern match *.bar I'd like to add a third queue to this exchange that receives messages that are neither foo messages nor bar messages. If I bind this queue with a # routing key, I naturally get all messages I need, but including foo 's and bar 's which I don't want. Any way to route messages patching a pattern NOT *.foo AND NOT *.bar

消息队列RabbitMQ入门介绍

（一）基本概念 RabbitMQ是流行的开源消息队列系统，用erlang语言开发。我曾经对这门语言挺有兴趣，学过一段时间，后来没坚持。RabbitMQ是AMQP（高级消息队列协议）的标准实现。如果不熟悉AMQP，直接看RabbitMQ的文档会比较困难。不过它也只有几个关键概念，这里简单介绍。 RabbitMQ的结构图如下： 几个概念说明： Broker：简单来说就是消息队列服务器实体。 Exchange：消息交换机，它指定消息按什么规则，路由到哪个队列。 Queue：消息队列载体，每个消息都会被投入到一个或多个队列。 Binding：绑定，它的作用就是把exchange和queue按照路由规则绑定起来。 Routing Key：路由关键字，exchange根据这个关键字进行消息投递。 vhost：虚拟主机，一个broker里可以开设多个vhost，用作不同用户的权限分离。 producer：消息生产者，就是投递消息的程序。 consumer：消息消费者，就是接受消息的程序。 channel：消息通道，在客户端的每个连接里，可建立多个channel，每个channel代表一个会话任务。 消息队列的使用过程大概如下： （1）客户端连接到消息队列服务器，打开一个channel。 （2）客户端声明一个exchange，并设置相关属性。 （3）客户端声明一个queue，并设置相关属性。 （4

Trying to connect to MQ using PHP; almost there

由 最后都变了- 提交于 2019-12-10 12:48:52
问题 So I've spent the past few days trying to solve this that seems to have been forgotten since none of the two PECL extensions available (SAM and mqseries) have been updated for a long time. I've tried both and mqseries seems to get me the furthest at this point since SAM refuses to get me a connection, even though MQ works perfectly from the command line. I've successfully created a connection to my QueueManager and it's during the next step (MQOPEN) that I fail miserably: $mqcno = array(

WAS MQ 7.5.x Queue access control

由 自作多情 提交于 2019-12-10 12:22:50
问题 I have a qmgr QM1 and local queues Q1 and Q2 . There is a SVRCONN channel with MCA set to mqm . There are multiple application connect to my QMGR for example APP1 and App2 . I want App1 only have PUT authority which means ONLY PUT message to Q1 or Q2 and App2 only have GET authority to ONLY GET message from Q1 or Q2 . Is there any advice. 回答1: Each unique set of authorizations needs to be attached to a group. Then when the app connects it needs to do so as a user ID in the appropriate group.

gradle+springBoot2.2集合ActiveMq

springBoot集成AcitiveMq的时候，由于springBoot的版本不同，所有会出现不同的问题。 当我们在启动连接池的时候有的时候会出现：启动项目会报错，提示JmsMessagingTemplate无法注入、 这个时候，你可以参考： https://blog.csdn.net/eumenides_/article/details/91850332 可能是你引入jar包的问题。 我们以springBoot2.2为例 第一步：引入jar包。 compile('org.springframework.boot:spring-boot-starter-activemq') compile group: 'org.messaginghub', name: 'pooled-jms', version: '1.1.0' 在这个地方一定要切记： 不能再引入springBoot的时候，把geronimo的包去除了。因为ActiveMq需要这个包。下面的要注解掉。 config.exclude group: "org.apache.geronimo.specs" config.exclude group: "com.google.code.findbugs" 第二步：在代码中引用mq 在启动类里添加： @EnableJms 所以接下来，在需要的controller层，引入redis /**

题目链接： http://118.190.20.162/view.page?gpid=T56 题目分析 一开始看到题目描述以为是一道有点意思的算法题，看完数据范围1 ≤ n ≤ 1000，1 ≤ m ≤ 1000，发现原来是普通的模拟题。 需要用到一个mark数组记录各个编号学生所在的位置，每次调整队列时，先通过mark数组得到第p号学生的位置，然后根据q的正负值对p号学生的位置进行调整， 调整的过程中要记得更新mark数组的值 。虽然做下来是 O ( m q ) O(mq) O ( m q ) 的时间复杂度，但是跑得挺快的hhh。 代码如下 # include <iostream> # include <algorithm> using namespace std ; const int maxn = 1005 ; int n , m , p , q ; //a[i]表示i号位置站的学生编号，mark[i]表示i号学生的位置 int a [ maxn ] , mark [ maxn ] ; int main ( ) { ios :: sync_with_stdio ( false ) ; cin . tie ( 0 ) ; cin >> n >> m ; for ( int i = 1 ; i <= n ; i ++ ) { a [ i ] = i ; mark [ i ] =
