Good point.
#3 In the above example where you say the Group ID will have ABCD00000000000000000000, will there only ever be one message on the queue with ABCD00000000000000000000?

And don't forget, if you are moving messages between systems with different CCSIDs, the fields you are using will NOT be converted.
Been there, and done this, and it's a really, really bad idea.
Cheers,

Vitor : we ran some etst and performance is ok.
Markt : you are tight - "ABCD" plus enough Blank chars to fill MQCHAR24.
It is still a "substring" of MsgId", that has "ABCD" ( shop id ) plus "0000/00/00" (date), plus "00:00:00" (time) plus some chars more.
Peter : I know you know this thread is "paralel" to another one ...
Yes, the queue shall hold 3.000 messages next month, around 5.000 messages in one yoear. Each msg is around 400 KB.
Yes, after the MsgId (or GroupID) is found, the messages is read, extracting it from the queue. So the queue shall hold only the catalogs for the shops that have not updated yet their price list.
This is, the producer puts 3.000 messages, and the end of the day the queue shall be empty, based on timezone opening hours.
Two catalogs for the same shop ? Not very usual to change the price twice in a day, but still possible. We want to "browse" for a message using "GroupID", and once we have we shall Read it using Msg_Id, provided by the previous "Browse". And in 10-15 minutes the shop shall read ( or try to read) the following catalog ...
Correl_Id : you are right. No known reason why we dont use it. Just watched the docs and saw GroupId was also MQCHAR24, found GMO_MATCH_GROUPID, and "voilà " ...
Eddie - no problem with CCSIDs - we generate the IDs and also read them.
>>> thanks all of you ! Seb. |
