Subject [jira] [Commented] (GERONIMO-5987) The ActiveMQ working directory and port are not referenced correctly - multiple instances not possible
Date Thu, 02 Jun 2011 20:17:47 GMT

    [ https://issues.apache.org/jira/browse/GERONIMO-5987?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13043024#comment-13043024
] 

Russell E Glaue commented on GERONIMO-5987:
-------------------------------------------

Apparently there are two places in which the ActiveMQ Host and Port could be configured in
a bundle deployment.
1. var/config/config-substitutions.properties
2. etc/blueprint-activemq-placeholder.cfg
(The fact that the second file has the word "placeholder" in the file name makes me curious
about the developer's status of the ActiveMQ plugin.)
Configuring the port in either file is not utilized by ActiveMQ
Also, the "activemq.data" working directory can be configured in the second file. But ActiveMQ
does not utilize that either.

> ActiveMQ is configured to run as "org.apache.geronimo.home.dir/var/activemq" and port
61616, and does not cooperate with multi-server configurations, nor does it use the PortOffset.
This is the use of the "org.apache.geronimo.server.name" option and PortOffset in "var/config/config-substitutions.properties".
(see: https://cwiki.apache.org/GMOxDOC30/running-multiple-geronimo-instances.html)
> First, Problem with working directory
> When wanting to run more than a single server instance, the ActiveMQ startup will block
waiting for the lock file "$GERONIMO_HOME/var/activemq/lock" to become available.
> Obviously this causes any server instance started after the first server instance is
started to block during startup while waiting for the lock file to become available.
> Second, Problem with PortOffset
> When configuring the PortOffset in  "var/config/config-substitutions.properties", all
Geroniomo components expect and attempt to connect to ActiveMQ at the port {ActiveMQ + PortOffset}.
However, regardless of what you set the PortOffset to be, the ActiveMQ service only ever binds
to port 61616, the default configured port (or whatever you have the port set as for this
service).
> Steps to repeat working directory problem:
> 1. Download and unpack G3.0 SNAPSHOT (3.0-20110523 tested)
> 2. Create the server instances:
> -- 2A. cd ${GERONIMO_HOME}
> -- 2B-1. mkdir gserver1
> -- 2B-2. cp -rp var gserver1/
> -- 2B-3. cp -rp etc gserver1/
> -- 2B-4. cp -rp repository gserver1/
> 3. update the "PortOffset" parameter in gserver1/var/config/config-substitutions.properties
for the gserver1 instance.
> 4. Start the default instance and gserver1 instance:
> -- bin/startup
> -- env GERONIMO_OPTS=-Dorg.apache.geronimo.server.name=gserver1 bin/startup
> 5. `tail -f gserver1/var/logs/geronimo.log` and you will see this as the last line that
outputs:
> "2011-05-31 16:26:39,609 WARN  [AMQPersistenceAdapter] Waiting to Lock the Store var/activemq"
> The server waits here indefinitely.
> 6. Shutdown the default instance and you will see the "gserver1" instance continue on
in the startup procedures. (of course you will see errors due to the PortOffset problem)
> * If I first start the "gserver1" instance by itself (before starting the default instance),
the directory "org.apache.geronimo.home.dir/var/activemq" is created and populated. Instead
it should be "org.apache.geronimo.home.dir/org.apache.geronimo.server.name/var/activemq" that
is created and populated.
> * Probably the patch should be to reference the ActiveMQ working directory as "org.apache.geronimo.server.dir/var/activemq"

> This is the two error messages you receive when configuring PortOffset to 100 (for example).
The second error message, regarding XAResource, repeats:

> This one reveals the problem that ActiveMQ ia not using PortOffset. RecoveryController
wants to connect to ${ActiveMQ + PortOffset} (61616 + 100).

> In this tested scenario, ActiveMQ is binding to port 61616, even though the PortOffset
value is 100.
