[omniORB] Question about ORB configuration

[Thomas Zumbiehl]

Hi Duncan,

Yes, I ment Bi-directional GIOP.
And, yes, I did read the manual chapter on connection and thread management.

The latest configuration I got on both A and B servers is :
scanGranularity=5

clientTransportRule=* tcp,bidir
offerBiDirectionalGIOP=1
oneCallPerConnection=0
maxGIOPConnectionPerServer=200
outConScanPeriod=600

endPoint=giop:tcp::0
serverTransportRule=* tcp,bidir
acceptBiDirectionalGIOP=1
maxServerThreadPerConnection=200
maxServerThreadPoolSize=200
inConScanPeriod=600

Do you think this is correct ?

Cheers,

Do you mean Bi-directional GIOP?  If so, that limits things somewhat...

What thread and connection parameters are you currently using?  Have you read the manual chapter on connection and thread management?
