Hi All

I have few Query as listed below

1) I want To transfer the Files (Large Size Doccumentssay a word doccument / PDFs) through MQSeries Is it possible through Client Server Scenario or You need to have Server - Server Connection in the Distributed Enviroment

2) This Question may look silly I just want to know whether is it possible to have File transfer Scenario using Publish Subscribe where the subscriber gets the File (Word/PDFs ) as the Subscription rather than Message

All types of Comments are welcome

Note : All the Transfer of file involves the File transfer from AIX,NT/200,Linux,AS/400 only say in diffrent Countries

Thanks

1) Size isn't important

You can send large numbers of large messages using client-server - it doesn't have to be server-server. BUT of course instead of merely stufing the data into a queue using local disk transfer, your application will have to sit and wait until it is finished the network transfer of course...

2) There's no such thing as a silly question, only a silly answer

And I hope this isn't it....never used Pub-sub myself but AFAIK your susbscribers get a message - what else can they can get from MQ?

I have just finished my project about File transfert for my company. We do that with OS390's Server to NT's Server.

I have met differents problems like :
1) Large files, Word doc (binary type) and so on.
2) Even if MQSeries can put a message until 100MB. You should think about log file (when QMGR failed) and the number of messages you send. 3) When you transfert a large file (350 MB for example) how are you going to ensure that you receive completely all splitting messages ?
4) How are you going to use the syncpoint when errors occur during the transfert?
5) MQSeries process will work hard to convert differents characters before putting to a queue.

We have resolved those problems by deciding the size maximum (not over 4 MB) : one message = one message

You can have a look at the AMI (Application Message Interface) on IBM site. It is free and I am sure that it is very usefull for you. There is also the Publish Subscribe sample too.
