Subject meaning of property-name="local" in Farming
Date Mon, 09 Nov 2009 12:33:56 GMT
Hi All

Could you please tell me what is the significance of property name="local"
in org.apache.geronimo.farm.config.BasicNodeInfo.
When I give "local"= true in clustering environment and try to deploy one
application, I am getting error like "Configuration already exists". I have
also checked cluster-repository dir of app server dir, one new empty dir has
been created there.

I have followed these steps:

1. Installed two geronimo instances A and B at different paths

2. Made the following changes to Geronimo A
For var\config\config-substitutions.properties
clusterNodeName=NODE --> clusterNodeName=NODE-A

For var\config\config.xml, add the following contents to module:
org.apache.geronimo.configs/farming/2.1.4/car
-----------------------------------------------------------------
<gbean
name="org.apache.geronimo.configs/farming/2.1.4/car?ServiceModule=org.apache.geronimo.configs/farming/2.1.4/car,j2eeType=NodeInfo,name=NODE-B"
gbeanInfo="org.apache.geronimo.farm.config.BasicNodeInfo">
<attribute name="name">NODE-B</attribute>
<attribute
propertyEditor="org.apache.geronimo.farm.config.BasicExtendedJMXConnectorInfoEditor"
name="extendedJMXConnectorInfo">
<ns:javabean
class="org.apache.geronimo.farm.config.BasicExtendedJMXConnectorInfo"
xmlns:ns4="http://geronimo.apache.org/xml/ns/attributes-1.2" xmlns:ns="
http://geronimo.apache.org/xml/ns/deployment/javabean-1.0" xmlns="">
<ns:property name="username">system</ns:property>
<ns:property name="password">manager</ns:property>
<ns:property name="protocol">rmi</ns:property>
<ns:property name="host">localhost</ns:property>
<ns:property name="port">1109</ns:property>
<ns:property name="urlPath">JMXConnector</ns:property>
<ns:property name="local">true</ns:property>
</ns:javabean></attribute>
</gbean>
-----------------------------------------------------------------

3. Made the following changes to Geronimo B
For var\config\config-substitutions.properties
clusterNodeName=NODE --> clusterNodeName=NODE-B
PortOffset=0 --> PortOffset=10

For var\config\config.xml, add the following contents to module:
org.apache.geronimo.configs/farming/2.1.4/car
-----------------------------------------------------------------
<gbean
name="org.apache.geronimo.configs/farming/2.1.4/car?ServiceModule=org.apache.geronimo.configs/farming/2.1.4/car,j2eeType=NodeInfo,name=NODE-A"
gbeanInfo="org.apache.geronimo.farm.config.BasicNodeInfo">
<attribute name="name">NODE-A</attribute>
<attribute
propertyEditor="org.apache.geronimo.farm.config.BasicExtendedJMXConnectorInfoEditor"
name="extendedJMXConnectorInfo">
<ns:javabean
class="org.apache.geronimo.farm.config.BasicExtendedJMXConnectorInfo"
xmlns:ns4="http://geronimo.apache.org/xml/ns/attributes-1.2" xmlns:ns="
http://geronimo.apache.org/xml/ns/deployment/javabean-1.0" xmlns="">
<ns:property name="username">system</ns:property>
<ns:property name="password">manager</ns:property>
<ns:property name="protocol">rmi</ns:property>
<ns:property name="host">localhost</ns:property>
<ns:property name="port">1099</ns:property>
<ns:property name="urlPath">JMXConnector</ns:property>
<ns:property name="local">true</ns:property>
</ns:javabean></attribute>
</gbean>
-----------------------------------------------------------------

4. Started both Geronimo A and B

5. Ran the following commands in Geronimo_A_Path\bin
deploy --user system --password manager start
org.apache.geronimo.configs/farming/2.1.4/car
deploy --user system --password manager --port 1109 start
org.apache.geronimo.configs/farming/2.1.4/car

6. Deployed one sample hello2.war in Geronimo_A_Path\bin

deploy --user system --password manager deploy --targets
org.apache.geronimo.configs/farming/2.1.4/car?ServiceModule=org.apache.geronimo.configs/farming/2.1.4/car,j2eeType=ConfigurationStore,name=MasterConfigurationStore
%PATH_SAMPLE%\hello2.war

Getting errors in command prompt:

------------------------------------------------------------------------
    Error: Unable to deploy hello2.war: java.io.IOException: See nested

        See nested

        Configuration already exists:
    org.geronimo.samples/hello_G_SLAVE/2.1.1.2/car
-------------------------------------------------------------------------

I have checked in the app server dir and new dir
%Location%\NODE_A\cluster-repository\org\geronimo is created now but its an
empty one.

Geronimo_A Log output:

2009-11-09 16:05:46,875 ERROR [RepositoryConfigurationStore]
%Location%\NODE_A\cluster-repository\org\geronimo\samples\hello_G_SLAVE\2.1.1.2\hello_G_SLAVE-2.1.1.2.car
is not an empty directory
2009-11-09 16:05:47,171 ERROR [Deployer] Deployment failed due to
