Release date:Updated on:Affected Systems:
Ibm mq Light
Description:
CVE (CAN) ID: CVE-2015-1955Ibm mq Light is a new message service based on IBM Bluemix.A security vulnerability exists in the implementation of ibm
Processing of RHF2 message headers in ibm mq message middleware jms messages, mqrhf2
When the company's technical platform is connected to a brokerage with ibm mq message middleware, the message header information is added to the message sent to MQ: RHF2, resulting in abnormal message receiving and processing. Record how the problem is handled here.

MVC + MQ + WinServices + Lucene. Net Demo,
Preface:
I have never been familiar with Lucene. Net before. Recently, many great gods have been reading this article in the garden, which is very enlightening. Adhering to the spirit of "practice with real knowledge", combined with the actual situation of the company's projects, we have the idea of writing a Demo, which is a test of our own capabilities.
Function Description:
1. After the front-end website
IBM WebSphere MQ is used to provide message transmission services in enterprises. When executing the following entries, IBM WebSphere MQ 7.1 unexpectedly interrupts and generates an FDC file. The implementation vulnerability exists. After successful exploitation, attackers can cause application crashes. PIDS:-5724H7220LVLS:-7.1.0.0Product Long Name:-WebSphere MQ

Let's start with a brief introduction to WebSphere MQ and installation
WebSphere MQ: A cross-platform feature for transmitting information.
1 Install WebSphere MQ and start
2 WebSphere MQ establish queue Manager (e.g. MQSI_SAMPLE_QM)
3 Establish the queue type select a local type (such as LQ)
4 Establish channels
Brief introduction
IBM WebSphere MQ Messaging provider in IBM WebSphere Application Server V7 provides complete support for Java™ channel exports. Exit is the user code that runs at the specified point in the IBM®WEBSPHERE®MQ channel lifecycle. There are many possible uses for channel exits, including auditing, security, compression, conversion, and so on.
In the previous version of WebSphere application
Zbus = MQ + RPC + PROXY
Support for Message Queuing, publish subscriptions, RPC, proxy (TCP/DMZ)
Billion-tier message stacking capability, HA-enabled high availability
Single jar package No dependency ~300k
Service agent-adapting to transform existing business systems to provide cross-platform and language
Rich Api--java/c/c++/c#/python/node.js Multi-language access
Zbus-dist Select zbus.sh or Zbus.bat to execute directly
Currently there are many MQ products in the industry, we make the following comparisons:RabbitMQis an open source message queue written using Erlang, which itself supports a lot of protocols: Amqp,xmpp, SMTP, STOMP, and so on, making it very heavyweight and more suitable for enterprise-class development. A broker framework is also implemented, which means that messages are queued in the central queue before they are sent to the client. Good support fo
MQ for Linux install and uninstall "Go"First, installation steps:1. Log in to the system with the root account2. The MQ installer needs to install the code under directory/OPT/MQM, save the data to the directory/VAR/MQM, and make sure that there is enough disk space in the relevant directory3. Create a group and user named "MQM" and specify the user's directory as/VAR/MQMSet up a user group MQM, note: The g
With the development of computer network and distributed application, remote message transmission is becoming an indispensable part of application system.
The emergence of commercial message middleware ensures the reliability, high efficiency and security of message transmission, and also reduces the development cycle of the system.
Currently, the most widely used message middleware products are IBM MQSeries.
The Dongfeng piping System is communicated through
Message Queuing (Mq,message queue) in the message data transmission of the preservation of data communication provides a guarantee and real-time processing convenience, here we take a look at the python thread of the MQ Message Queuing implementation and the advantages of Message Queuing analysis
Message Queuing is the container in which messages are saved during the transmission of a message. The Message
The MQ Queue Manager cannot be stopped by using the endmqm command. What should I do?

The MQ Queue Manager cannot be stopped by using the endmqm command. What should I do?
Generally, you can use endmqm to stop the MQ queue manager. However, in some special case
Set the trigger on the queue of ibm mq and call the application to process the message when the message reaches the queue.
1. Specify a trigger for the queue. You can create a queue in the following way:
Mq1 is the name of the queue manager.
Runmqsc mq1Define QL (Q. init) replaceDefine QL (testq) trigger trigtype (every) process (testproc) initq (Q. init) replace
2. Define the process to be called:
Define process (testproc) applicid ('d:/temp/tes
1. Compliance with JMS specifications
MQ complies with the JMS specification and Kafka does not follow the JMS specification. Kafka uses file systems to manage the lifecycle of messages
2. Throughput
Kafka is a sequential write disk, so the efficiency is very high. Kafka deletes messages based on time or partition size, while broker is stateless, consumer consumption status (offset) is controlled by consumer itself (each consumer instance consumes
Why Message Queuing (MQ) is required.

The main reason is because in high concurrency environment, due to too late synchronous processing, the request will often occur congestion, for example, a large number of insert,update and other requests to reach MySQL, directly resulting in countless row lock table lock, even the final request will accumulate too much, the
