Hi Fernando,

Thanks for your answer.
If you see the messages on the CDI there is a answer from Jonny what they talk about the new parameter:

Probably this is the same solution what you talk about.
I tested this parameter on xC7 and appear no have effect.

And yes, I have this issue in two clients with mach active..

Hello Cesar.
Someone else already mentioned this. There is (or should be) a new option
that tells the CM to use only the ALIAS listed in the local (from the CM
point of view) SQLHOSTS.

This should be included in *FC8 when available.
I was involved (from a customer point of view) in this issue, but I didn't
have the opportunity to test it.
If you have any issue with it I'd like to know...
