I have a Message Flow that has 10 MQInput Nodes and everything seems to work fine most of the time. Every so often I get the following errors in my AIX Broker log:

It seems to happen randomly, sometimes for multiple messages in a row then everything works again???

Any help would be appreciated.

thanks

I followed the instructions and still have the same issue.

From the notes in the link, I have the following values:

maxuproc = 1200
processess running = 33
maxappls = 40
avg appls = 1

Should I try increasing maxappls? If so do you know how, I looked through the DB2 books but only found out to view it.

Any other ideas?

I am running DB2 7.1.0

Try increasing maxappls parameter to 100. I would also increase avg_appls to 5.
Using DB2 control Center select configure.. for your database by right clicking on it. Under Applications tab, you will see parameters, maxappls, avg_appls.

It's DB2 for AIX. I assume those instructions were for NT?

Found it in the manual.

For anyone else following along that cares....it's:

UPDATE DATABASE CONFIGURATION FOR dbname USING MAXAPPLS 100

Didn't help though. Still getting same errors. Seems like it works for a few messages then breaks for a few and then works again. The most I have seen it work for is 4 messages in a row.

What happens when we have millions of messages going through this thing?

I got around this issue by implementing the TCP/IP loop-back.

The problem is that AIX is (for some unknown reason) unable to create several DB2 connections through shared memory and you have to make the DB2 connections through TCP/IP although the DB2 resides on the very same AIX system.

A similar operation is described in:
