It only supports sending to a “Queue” object. Also, it is not possible to directly connect to a “Topic” (2) object. The BizTalk MQSC adaptor cannot directly specify a “TopicString” in the adaptor. NET it is possible to directly make use of “Subscriptions” (1) on IBM MQ, without a topic object (2), by specifying the “TopicString” while sending a message. When using the IBM MQ Client library for. BizTalk MQSC Adapter – Send to IBM MQ Topic/Subscription In the future we might be able to move to the IBM MQ REST API as more features will be added. We are using this solution now for more then 6 months without any issues. I don’t think IBM approves this approach, but it works for what we need it. The question is if this approach is advised… In the end I am happy that I was able to build a solution for the problem. In the sample a showcase the functionality described in the table at the beginning of this post. To help you get started, I added my sample proof of concept solution to GitHub in the MqPcfAutomation repository. This seemed less easy then I thought, I spend a lot of time figuring out what dependencies I needed. Now that we have our DLLs, we can add them to our. You will find the output in the source directory of the JAR files: Ikvmc -target :library -sharedclassloader I have the IBM client installed, so the JAR files will be on there default installation (C:Program FilesIBMMQjavalib)

Download (and Install) the IBM MQ redistributable client (in order to extract the JAR files).The whole process consists basically out of 3 steps: Using IKVM.NET is not that easy when you use it for the first time. Now I will shortly explain how we were able to put it all together. NET assemblies and use the supported and documented IBM Java Packages from a. Using IKVM.NET we should be able to convert the IBM JARs to. NET.“īased on this description it sounded like it could offer a possible solution! It also includes a port of the OpenJDK class libraries to. It can both dynamically run Java classes and can be used to convert Java jars into. IKVM.NETĪfter some searching I stumbled upon IKVM.NET: NET platform was a requirement at that time, because the whole build and deployment pipeline was focused on. Using JAVA seemed to be the only alternative if we wanted to build this custom REST API with all features. All other tasks we wanted to automate are possible in. NET PCF namespaces are not supported/documented by IBM and do not provide the possibility to inquired the existing subscriptions on a queue manager. The IBM MQ REST API was not a possible alternative at that moment in time. For my current project we wanted to build a custom REST API to automate object creation based on our custom needs. Programmable Command Formats (PCFs) define command and reply messages that can be used to create objects (Queues, Topics, Channels, Subscriptions,…) on IBM Websphere MQ. NET support for PCF in the IBM client, but we can use IKVM.NET to convert JARs to DLLs so we can still use. NET using IKVM.NETīy Jeroen | | BizTalk Community Blogs via Syndication So this may cause your MSMQ Storage folder large issue.Automate IBM MQ object creation with PCF in. Note - only truly empty storage files are removed - one lonely message will keep a storage file active as MSMQ performs no defragmentation or compaction. You can modify this time by changing the following registry entry on the local computer. When messages are deleted, only message storage files that have no messages in them are deleted.īy default, these files are cleaned up only every six hours. The only restriction to how messages are stored in these files is that a single message cannot span multiple files. Each file may contain messages from multiple queues, and conversely,Ī single queue's messages may be stored in several files. A single file does not represent the messages of a single queue.

mq extension represent memory-mapped files where messages are stored. The files in the MSMQ\Storage folder include message files (xxxxxxxxx.mq files), a history file (QMLog file), and state files for received message (MQInSeqs.lgx files) and transaction operations (MQTrans.lgx files).
