Described below is how to set up Deployment Synchronizer for a WSO2 product cluster using two cluster nodes (master, and one slave) with a shared registry (WSO2 Governance Registry). For information on clustering, refer to section Clustered Deployment.
Assume you have Master and Slave nodes, and a shared registry. The Master node will act as a Registry Read-Write (RW) Node, and the slave as a Registry Read-only node.

svnadmin create /home/test/mylocalsvnrepo |
The file:// protocol can be used instead of setting up http:// url for the repo (by using a webserver like Apache) if the repo is in local system. For example, you can do a manual checkout of the repository by using the command,
| Code Block |
|---|
svn checkout file:///home/test/mylocalsvnrepo/ |
4. To configure the Deployment Synchronizer, you have to simply edit the following code block in <PRODUCT_HOME>/repository/conf/carbon.xml file of the product's Master node.
| Code Block | ||
|---|---|---|
| ||
<!-- Deployment Synchronizer Configuration. Uncomment the following section when running with "svn based" dep sync.
In master nodes you need to set both AutoCommit and AutoCheckout to true
and in worker nodes set only AutoCheckout to true.
-->
<DeploymentSynchronizer>
<Enabled>true</Enabled>
<AutoCommit>true</AutoCommit>
<AutoCheckout>true</AutoCheckout>
<RepositoryType>svn</RepositoryType>
<SvnUrl>http://svnrepo.example.com/repos/</SvnUrl>
<!-- <SvnUrl>http://svnrepo.example.com/repos/</SvnUrl> -->
<SvnUser>username</SvnUser>
<SvnPassword>password</SvnPassword>
<SvnUrlAppendTenantId>true</SvnUrlAppendTenantId>
</DeploymentSynchronizer>--> |
- Auto Commit - Allows to perform commit operations automatically.
- Auto Checkout - When this option is selected, an additional option named "Use Eventing" will be enabled.
- Use Eventing - Allows to trigger checkout actions on registry events. This is not needed most of the time.
- Synchronization Period - Synchronizer will get initialized and start running periodically as specified in this parameter. Default is 10 seconds.
7. Add content as the following example to the product's slave node(s).
| Code Block | ||
|---|---|---|
| ||
<DeploymentSynchronizer>
<Enabled>true</Enabled>
<AutoCommit>false</AutoCommit>
<AutoCheckout>true</AutoCheckout>
<RepositoryType>svn</RepositoryType>
<SvnUrl>file:///home/test/mylocalsvnrepo/</SvnUrl>
<!-- <SvnUrl>http://svnrepo.local.com/repos/</SvnUrl> -->
<SvnUser>test</SvnUser>
<SvnPassword>password</SvnPassword>
<SvnUrlAppendTenantId>false</SvnUrlAppendTenantId>
</DeploymentSynchronizer> |
The only differences between the Master and Salve configs are that in slave nodes, we set AutoCommit to false, and AutoCheckout to true.
8. The Deployment Synchronizer setup is complete. Start the Governance Registry and the two product nodes and examine how uploads to the master node gets synchronized to the slave nodes accordingly.
