Can't have two instances of Phoenix running on same machine?
I am running hsqldb inside hsql avalon block.
I am using Phoenix4.0. hsqldb 1.7.1
I created two phoenix directories one for development
and one for PA product assurance. My intent was to be
able to have both development and PA running on the
same machine. I can already do this with Tomcat by
changing port attributes in server.xml.
I changed the port and the database file parameters in
config.xml in the SAR for the PA instance and started
it running.
When I tried to run development phoenix instance, at
same time, I got following error:
-----------------------------
INFO 2002-10-21 16:12:15.421 [Phoenix ] (): Logger
started
WARN 2002-10-21 16:12:15.500 [Phoenix ] (): Phoenix
was not started by the daemon thus it will not be
possible to restart the JVM via the Management
interface.
FATAL_E 2002-10-21 16:12:16.046 [Phoenix ] (): There
was a fatal error while starting Embeddor.

-----------------
There seems to be a port being used that I am not
aware of and have no way of changing.
2)Is this port "JVM_Bind" part of Phoenix?
If so, and I cannot run more than one Phoenix
environment on a machine then I suppose I could put
both SARs in one Phoenix environment. I will try that
next.
3)Assuming that works, is there a way to bring down
and startup a given SAR as opposed to bringing down
entire Phoenix system itself?
Another subject:
4a)I have been shutting Phoenix down using cntrl-C.
Is there another preferrable way to shut the server
down?
4b)After shutting down Phoenix the db.properties
indicates modified=yes. This means that changes to
database have not been saved/commited to the data
file. I would like to do SHUTDOWN COMPACT on hsqldb
when Phoenix shuts down. I can't see any mechanism in
DefaultHypersonicSQL.java nor in
HypersonicSQLHandler.java for implementing this.
How can I do this?
Thanks and Regards, Jim

Okay - still can't reproduce it. What version of Linux are you ising. I am
testing on Mandrake 7.x with kernel 2.4.18-6mdksecure and using libc-2.2.4
Theres quite a few problems with RH7.2 and some Sun JDKs. Would this be the
combo that causes the error?

Okay will look into it. Before I do can you make sure that the ext directory
does not have any jars in it that it shouldn't and that the phoenix directory
is also clean (with no stray jars) and that the kernel.xml is unmodified (or
if modified could you send it to me).

I don't know of any documented ones... but I had troubles with IBM's
JDK with Tomcat and Phoenix that I didn't have with Sun's (this was all
1.3.1). Since Sun's didn't work I didn't investigate further (and this

Baffling Exception
Posted by "Peter M. Goldstein" <pe...@yahoo.com>.
Ok folks, I've got a doozy of an error.
When one of our developers starts Phoenix 4.0.1 running James, he gets
the following:
INFO 2002-10-21 18:52:09.222 [Phoenix ] (): Logger started
WARN 2002-10-21 18:52:09.612 [Phoenix ] (): Phoenix was not started

nents(DefaultEmbeddor.java:507)
This exception trace starts with a NPE, to a standard call to
getValueAsInteger on an AbstractConfiguration subclass. Tracing the
code in AbstractConfiguration we see something that looks like:
String value = getValue().trim();
Which will obviously produce an exception if getValue() is null. All
good so far.
Now, getValue() should, according to the implementation of
DefaultConfiguration, throw a ConfigurationException if the value to be
returned is null. Because of the code in AbstractConfiguration, this
seems to be a requirement for subclasses of AbstractConfiguration, lest
you generate NPEs.
Ok, here's the baffling part - is there another subclass of
AbstractConfiguration being used? I can't find one - the only one in
use seems to be DefaultConfiguration. But DefaultConfiguration throws a
ConfigurationException upon encountering a null value. So there
certainly shouldn't be an NPE.
Here's more of the baffling part - I don't see this problem when I start
the server on Windows. So on Windows there is no NPE, while on Linux we
see a seemingly impossible NPE. Any thoughts? Anyone who knows the
internals of Phoenix wish to comment (Peter D., perhaps)?

Jim,
Easy: in one of the phoenix conf dirs, edit kernel.conf and change the
MX4J port from 8082 to something else. That or run without MX4J.

inside PHOENIX_HOME/conf/kernel.xml, there is the "SystemManager"
component.
There are two tags under there that could be causing this:
<manager-adaptor-port>8082</manager-adaptor-port>
<enable-rmi-adaptor>true</enable-rmi-adaptor>
'enable-rmi-adaptor' may be commented out, or set to false. if so,
don't worry about it. Otherwise, you want to set it to false on one of
the instances.
You also want to make sure the 'manager-adaptor-port' is unique on each
phoenix installation (I would just increment by one for the other
install)

Yes, using the web-based management interface. http://localhost:<port

On Windows I believe Control-C is preferrable at the moment (4.0). I
believe 4.1 has some batch file wrapper to start/stop

Is it possible to shutdown the server from the HsqlSocketRequestHandler
interface?
If so, by modifying DefaultHypersonicSQL to implement the Disposable
interface and calling the shutdown methods inside of dispose() would be
the preferred way to implement.
