I'd always thought that on OS/390 pagesets etc. came with some indexing functionality provided by the operating system. It would seem logical (to me) that MQ makes use of that functionality rather than inventing it's own. Because the storage mechanism on OS/390 is so different, it might be that the indexing can be configured on different "fields" in the message.
On the Windows/Unix platforms, the operating system does not provide such indexing facilities. Basically any data file (text file, html page, word document etc) are flat files like any other and contain a stream of bytes. The MQ software has no OS functionality to use so has to implement its own.

"This parameter is supported only on z/OS. On other platforms, retrieval optimization might be provided, but it is not controlled by a queue parameter." So it "might" be there, but if it is you can't touch it. Unfortunately, I don't think this settles the question one way or the other! -- T.Rob -----Original Message----- From: MQSeries List [mailto:[EMAIL PROTECTED] Behalf Of Robert Broderick Sent: Wednesday, August 18, 2004 10:24 AM To: [EMAIL PROTECTED] Subject: Re: Queue Indexing on Distributed Platforms R U sure??????? I was told that indexing was ONLY available on the OS390. Maybe what you say is true. Maybe this is a pre 5.3 condition. >From: "David C.
