Hi, Mike

Finally I've got the book and I eager to go through it. There are many issues
I am missing and I hope to find answers on many questions.

In the beginning of the book you ask send notes, tips etc. I plan to do it, it
is my first message.


1. Page 3: "The IIOP connection is used by theJaguar Manager administration
tool and is required for clusters and synchronization". Right, it also used
for connection to Jaguar from client application:

location=iiop://<jag server machine>:9000

2. Page 6. "Under this deployment configuration, any client accessing the
logical server Jaguar can use components in PackageA, but not in PackageB, and
PackageC." And for Jag2 vice versa.

I didn't try, but I think if on client side we create two instances of
Connection object and then ConnectToServer() them with different properties,
we can access all packages, but using different connection objects?

3. Page 10: "Before moving the components to another Jaguar server, it may be
necessary create ... database connection caches.." Then you mean
synchronization do it automatically. It is true for Jaguar 3.6, for 3.5 and
lower there was bug that was fixed:

"9110 217030 Syncronization: Doesn't copy Connection Cache Jaguar when
configured in a cluster will not copy Connection Cache entries." ( from list
of fixes)

Thank you,
Vladimir Uzlaner

P.S. Mike, if you find annoying such kind of messages, please, let me know. I
just like discussions and to be exact in issuing points.

Yep.
Unless you are using Web clients and accessing Java servlets using Jaguar's
HTTP listener.

Of coarse. The point of a logical server is to allow several clients to use
the same Jaguar server w/o getting out other packages (requires roles to
implement) and to partition an application in clustering and load balancing.

Glad it is fixed.
