Exactly what do you mean by size problem?

What evidence of size problem do you see? What errors are in the error logs?

Why do you believe that deleting a message from the SCTQ will resolve the problem?

HI,
Msg's which are above 10MB are getting strucked. When i'm removing that msg from my folder and uploading once again all the msg's are transmitting smoothly.

As these msg's are coming from another application, i can'tcontrol them so i want to delete them temporarily by filtering msg's on basis of size.

Exactly what is the size of the inbound messages? What is the max message length attribute of the destination queue? If the inbound messages are greater than 10MB, then the destination queue max message length must be >10MB.

Removing that message from what folder?

What messages are once again transmitting smoothly?

Filtering where? How?

The OP is almost certainly moving files through WMQ. Almost certainly without involving WTE.

So are they actually getting "strucked" in the SCTQ or not moving out of this folder of yours? If the latter, and removing them from this folder is resolving the problem, isn't it more likely the application is having the issue rather than WMQ?

Depends on the version of 6.0 and whether or not message compression is used...
Saw that problem in 6.0.2.6 and 6.0.2.7 in the cluster with message compression. Had to get a fix through PMR for it. (Running channel, message stuck in SCTQ for no apparent reason...)

My destination queue max. length is 99900000.

I receive msg's from another application and the msg's size may vary from 2KB to 20MB.
After Rxing all msg's, scheduled batch will be executed and all files are put in to SCTQ successfully.

If msg size is more than 10MB, allmsg's will struck in SCTQ, then
1. I will clear all msg's from SCTQ
2. Remove msg >10MB from folder
3. Re-execute batch, so that remaining msg's get txed.

So, is there any way for deleting a particular msg from SCTQ.

Have you tried setting BATCHSZ to 1 (one)? Have you considered that the issue you may be facing could be due to large persistent messages being transmitted?

Batch size is set to 50.
All my msg's should be in Persistent and it is compulsory for my application.

Did you set BATCHSZ to 1? Did you try again? What was the result?

So you have enough logs to hold 1000 MB? (50 *20 MB)?
You might want to use for sake of speed and expediency 2 overlapping clusters. One with batchsize 50 for small messages and one with batchsize 1 for the big messages...

Have fun

No you don't, you need to fix the problem, not the symptom...
