Hi.
Whether there's a parameter controlling the number of concurrent client connections?
I got a following situation:
- ASP.NET WebService client puts messages to some queue_01.
- some other application (application_B) Gets from the queue_01 and processes the messages.
If I run simultaneously 10 ASP.NET clients to Put messages in the queue_01 only 2 messages at a time Put in the queue_01. Other 8 clients are still waiting till those 2 messages will be retrieved (Get) by the application_B.
- how to enable all clients' messages being Put in queue without waiting others' ?
NOTE: platform and product version info:
Server OS: HP-UX 11.31 v3
MQ Server: 7.0.1.2
Thanks in advance.
Best Regards, |

additional info:
tried the below, with no changes in the Put behavior of the concurrent clients.
- MQPMO_ASYNC_RESPONSE on the client MQPutMessageOptions
- alter qlocal(Q.01) DEFPRESP(ASYNC) |

How about turning off conversation sharing on the channel?

Thanks for the clue.
tried the MQCNO_NO_CONV_SHARING in the client side and SHARECNV(1) on the chl definition. unfortunately no change in the behavior.
- anything that I could have missed?
the channel is:
| Code: |
dis chl(CHL.CLI.02)
2 : dis chl(CHL.CLI.02)
AMQ8414: Display Channel details.
CHANNEL(CHL.CLI.02) CHLTYPE(SVRCONN)
ALTDATE(2010-08-11) ALTTIME(09.54.55)
COMPHDR(NONE) COMPMSG(NONE)
DESCR( ) HBINT(300)
KAINT(AUTO) MAXINST(999999999)
MAXINSTC(999999999) MAXMSGL(4194304)
MCAUSER(mqm) MONCHL(QMGR)
RCVDATA( ) RCVEXIT( )
SCYDATA( ) SCYEXIT( )
SENDDATA( ) SENDEXIT( )
SHARECNV(1) SSLCAUTH(REQUIRED)
SSLCIPH( ) SSLPEER( )
TRPTYPE(TCP) |

- How could the licensing restrict number of concurrent Post's?
- Does this sound reasonable, providing I try with the "90 days free trial" edition?

I hope your qmgr is not a mainframe without CAF attached...
There is a limit of 7 client connections to a MF without Client Attachment Facility...

Actually the connection logic in the WebService side seems was the cause.
After modifying that now I could hit 24 concurrent Posts from the WebService in stress tests.
Will try further, but have no clues yet for "why 24" . |
