Can somebody give me your advice or suggestion about if you know a configuration or similar to use about 1000 conections o more in a configuration client-server, the server is a MQ installed in a Z/Os environment, currently we have our applications under client-server where which branch send the message one by one, the messages are sended using a connect/open,Get o Put/close/disconnect and this operations in days with the system are full the use of CPU is high (peak). Our proposal is to connect the 1000 connections, with this action we consider the CPU will be high only during the period of the connect and after the use of CPU will be decreased because the application don’t do the connect and disconnects actions.
The 1000 connections we are planning to connect using a java application in the windows environment.
Any help or advice will be appreciate.
Thanks a lot.
Regards.

Just Wondering Why do you need 1000 connetions for a Java Application
Is this a online Application from 100 Windows Servers where you do synchrous Messaging ?
Are the messages continuosly routed 24/7 from all these client Windows Servers , Or You can send them In Batches ,
If It is a Synchrous Connection , You have the option of Just Connect to Qmanager , Connect to Queue and wait indefinetly ,
Also there is MQPUT1 I believe where you can simply the open , put , close in one Call,
Also Check
------------------------------------------------
Connection pooling
WebSphere MQ classes for Java provides additional support for applications that deal with multiple connections to WebSphere(R) MQ queue managers. When a connection is no longer required, instead of destroying it, it can be pooled and later reused. This can provide a substantial performance enhancement for applications and middleware that connect serially to arbitrary queue managers.

Finally you may want to use Triggering on windows and send Messages in batches , Mq triggering is better way in some cases, |

hi,
this application have arround 1000 windows client (branches) and the communication is asyncronuos because if the message isn't in the reply queue the application response a timeout and the changes are rollbacked, the timeout is about 45 seconds.
