Hi Matt,
You must make sure that each pair of configuration file uses the same
virtual database name and same group name (in the Distribution element).
A good practice is to use different JGroups configuration files with
different multicast addresses for each virtual database to avoid traffic
collision between messages of different virtual databases.
If this does not help, feel free to post your configuration files so
that we can help you.
Thanks for your interest in Sequoia,
Emmanuel
Hey guys, I've got a setup of 2 controllers and 4 backends. On each
of my backends which are all MySQL I have a test1 and test2 database.
When I setup my virtualdatabase files I have called them db1-test1 and
db1-test2 and db2-test1 and db2-test2 and so on, all the way up to
db4-test2. When I load the configuration files for test1 vdb
everything loads up ok, No Problems. I'm then able to load db1-test2
and db2-test2 by loading the test2 xml file, but after that I'm unable
to load db3-test2 and db4-test2 because it says I can not use the same
backends or they are not compatible. I have checked my xml files with
a fine tooth comb and each line has different backend names and
backend locations.
db1-test1 points to jdbc:mysql://db1:3306/test1
db1-test2 points to jdbc:mysql://db1:3306/test2
db2-test1 points to jdbc:mysql://db2:3306/test1
db2-test2 points to jdbc:mysql://db2:3306/test2
db3-test1 points to jdbc:mysql://db3:3306/test1
db3-test2 points to jdbc:mysql://db3:3306/test2
db4-test1 points to jdbc:mysql://db4:3306/test1
db4-test2 points to jdbc:mysql://db4:3306/test2
If you need me to post the xml files I will do so, but I was hoping
someone might have a clue as to why when I load up the second set of
test2 database backends it complains about the backends. The error I
see in the console window is as follows...
Loading of virtual databases configuration file failed (because of The
virtual database test2 could not be added to the controller (because
of Error while joining group test2
(org.continuent.sequoia.common.exceptions.ControllerException: Virtual
database configuration is not compatible with other controller
settings.))).
Thanks so much in advance,
