Sharing Config Dir Between Several Synapse ESB's
Hi,
We are running synapse by configuring xml files (endpoints/proxy-services) in the repository/conf/synapse-config directory. Because of failure safety we would like to run further synapse esb's and share the configuration directory between these esb's. Therefor the hot update feature of the configuration directory should still be working and affect all running synapse esb's. We already looked at the sample 11 but we can't get the desired behavior. Is there a way to get this done?? Grateful for any help.
Thanks in advance.

I suppose you need to put your entire configuration as a single synapse.xml file in the HTTP server (similar to sample 11). This will not use regular hot deployment/update, but you should be able to dynamically update sequences and endpoints.
If you want to use regular hot deployment/update, you should use the SVN/Git based solution. This is probably the most elegant way to solve this problem in a distributed setting.
Thanks,

You can use the Simple URL repository of Synapse to point to some shared HTTP server, and put your configuration files in the HTTP server. Or you can check-in your configurations to a SVN/Git repo and deploy a script in each host to periodically checkout/pull the configuration files. You can even write a Synapse task to do this.

AW: Sharing Config Dir Between Several Synapse ESB's
Posted by "Mitchell, Jermaine" <Je...@tia.com>.
Hi,
we placed the configuration files in a HTTP Server under (http://localhost/synapse-config/). But when trying to use the Simple URL registry by configuring the registry.xml ...
<registry xmlns="http://ws.apache.org/ns/synapse" provider="org.apache.synapse.registry.url.SimpleURLRegistry">
<parameter name="root">http://localhost/synapse-config/</parameter>
<parameter name="cachableDuration">15000</parameter>
</registry>
... this doesn't affect anything. Is there something missing?
Thank you again for your help

When running Synapse servers on the same machine, you can probably change the Synapse config directory location to point to the same directory. This can be done by modifying the synapse.sh file. Locate the following command and change accordingly:
# synapse config
SYNAPSE_XML=$SYNAPSE_HOME/repository/conf/synapse-config
There are couple of approaches you can take to solve this problem in a distributed environment. You can use the Simple URL repository of Synapse to point to some shared HTTP server, and put your configuration files in the HTTP server. Or you can check-in your configurations to a SVN/Git repo and deploy a script in each host to periodically checkout/pull the configuration files. You can even write a Synapse task to do this.

Are you running all Synapse instances on the same host?
