![]() Each file may contain messages from multiple queues, and conversely, a 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). The information in these files is useful when you need to manually retrieve the queue number of a private queue, inspect the properties of a private queue, or determine the disk space being used to store the messages on a computer. These files cannot be stored on a compressed drive. This topic describes the message files found in the MSMQ\Storage folder and the queue registration files found in the …\MSMQ\Storage\Lqs folder. If the “FILTER” key is not specified or the value is set to something else, the exit can simply return without doing anything further.Applies To: Windows 10, Windows 7, Windows 8, Windows 8.1, Windows Server 2008, Windows Server 2008 R2, Windows Server 2012, Windows Server 2012 R2, Windows Server Technical Preview, Windows Vista If the condition satisfies, then rest of the code in the exit is executed. At the beginning of the entry point of the exit, a check for “FILTER”= “YES” can be made. For example., you can specify “FILTER”=”YES” with the transfer request. You can pass metadata, a key-value pairs of data with the transfer request for this purpose. ![]() You can however control whether the code in the exit is executed completely or not. You must note that the exit gets called for every transfer request submitted to an agent. The sample can be easily modified to pass file size limits as metadata with the transfer request itself. The sample reads an XML file to determine the minimum and maximum file sizes. The sample also contains instructions on how to compile and deploy the exit. Here is a sample exit that performs the above actions to filter files of specified sizes. Return the modified list of files back to agent to transfer files.Remove the filenames from the list whose size is out of the specified range.Keep the filename in the list if its size lies in the specified range.The source agent calls the exit with a modifiable list of files to transfer. SourceTransferEndExit - After the entire file transfer is completeįor our requirement here, i.e., transfer only those files whose size is in between the specified range, a SourceTransferStartExit can be used.DestinatonTransferEndExit - After the entire file transfer is complete.DestinationTransferStartExit - Before the entire file transfer starts.SourceTransferStartExit - Before the entire file transfer starts.There are four types of interfaces provided by MFT – The code in the exits is run before a transfer begins and completes at source and destination agents. These exits must be written in Java and implement certain interfaces defined by MFT. MFT provides interfaces to customize transfers through a concept called “exits”. Now what if the requirement is to transfer only those files whose size is in between, say 2KB and 10 KB (or any specified value)? ![]() Transfer only those files whose size did not change in specified number of monitor polls.Īs seen #2 above – resource monitor can be configured to initiate transfer of files whose size is equal to or greater than certain value.Transfer files whose size is equal to or greater than certain value, say 5KB.Transfer only those files that have an extension of “.doc” or “.pdf”.With filters, known as “match” conditions, you can further customize transfer definitions. Using resource monitors you can configure an MFT agent to automatically initiate transfers when an event occurs. Managed File Transfer eliminates costly redundancies, lowers maintenance costs, and maximizes your existing IT investments. You can use Managed File Transfer to build a customized, scalable, and automated solution that enables you to manage, trust, and secure file transfers. IBM MQ Managed File Transfer (MFT) transfers files between systems in a managed and auditable way, regardless of file size or the operating systems used.
