addtodeploymentdotxml

This utility adds a fragment of XML to a deployment.xml file for a running VoltDB database.

Is is not intended to be used on a production system.

It works by looking for a pattern - such as the word 'deployment'. It assumes the pattern is an XMl end tag and injects the new content in just before it. It then calls UpdateCatalog.

Example

Imagine we want to add an export connector to a brand new VoltDB database. Our extra XML is in a file called 'newbit.xml' and looks like this

<export>
    <configuration target="USER_TRANSACTIONS" enabled="true" type="file">
        <property name="type">csv</property>
        <property name="nonce">user_transactions</property>
        <property name="outdir">/Users/drolfe/Desktop</property>
    </configuration>
</export>

The deployment.xml looks like this:

<?xml version="1.0" encoding="UTF-8" standalone="yes"?>
<deployment>
    <cluster hostcount="1"/>
    <partition-detection/>
    <heartbeat/>
    <ssl/>
    <httpd enabled="true">
        <jsonapi enabled="true"/>
    </httpd>
    <snapshot enabled="false"/>
    <commandlog enabled="false">
        <frequency/>
    </commandlog>
    <systemsettings>
        <temptables/>
        <snapshot/>
        <elastic/>
        <query/>
        <procedure/>
        <resourcemonitor>
            <memorylimit/>
        </resourcemonitor>
        <flushinterval>
            <dr/>
            <export/>
        </flushinterval>
    </systemsettings>
    <security/>
</deployment>

We call our jar file and ask it to add newbit.xml just before '':
