19.2. Copying Deployed Applications Between Standalone Servers

While EAP 6 server groups manage content centrally for all group members, standalone servers are on their own. JBoss ON can help as an intermediary to sync application content between separate server instances. The addToCluster function has this as an option when joining a standalone server to a cluster. The copyDeployments function can copy deployments between any two standalone instances.
Invoking the function requires only the name of the source EAP 6 server (the one to copy the deployments from) and then the name of the target EAP 6 server (the one to copy the deployments to).
Assuming that you already know resource IDs of the two EAP 6 server resources, set the source and target resources. For example, in interactive mode: 
[root@server bin]# ./rhq-cli.sh -u rhqadmin -p rhqadmin
rhqadmin@localhost:7080$ var source = ProxyFactory.getResource(10381) 
rhqadmin@localhost:7080$ var target = ProxyFactory.getResource(10577) 
rhqadmin@localhost:7080$ copyDeployments(source, target)
The first part of the function gets the server resource IDs. 
function copyDeployments(sourceAS7, targetAS7) {
    if (typeof sourceAS7 == 'object') {
        sourceAS7 = sourceAS7.id;
    }

    if (typeof targetAS7 == 'object') {
        targetAS7 = targetAS7.id;
    }
All of the deployed applications are listed as children of the source JBoss EAP 6 server. The copyDeployments function retrieves each deployment by searching for all of the children of the server that are of a deployment resource type. 
    var deploymentResourceType = ResourceTypeManager.getResourceTypeByNameAndPlugin('Deployment', 'jboss-as-7');

    var deploymentsCrit = new ResourceCriteria;
    deploymentsCrit.addFilterParentResourceId(sourceAS7);
    deploymentsCrit.addFilterResourceTypeId(deploymentResourceType.id);

    var unlimitedPageControl = PageControl.unlimitedInstance;

    var sourceDeployments = ResourceManager.findResourcesByCriteria(deploymentsCrit);
    var iterator = sourceDeployments.iterator();
    while (iterator.hasNext()) {
        var deploymentResource = iterator.next();
        //get a resource proxy for easy access to configurations, etc.
        deploymentResource = ProxyFactory.getResource(deploymentResource.id);

	println("Copying deployment " + deploymentResource.name);
Each discovered deployment is then copied over as a new child resource to the target server. These are content-backed resources, so they are exported and uploaded as content. The function also searches for and pulls in the content metadata and the content history, so that any important historical information about the deployment is also copied over. 
        var installedPackage = ContentManager.getBackingPackageForResource(deploymentResource.id);
        var content = ContentManager.getPackageBytes(deploymentResource.id, installedPackage.id);

        var runtimeName = deploymentResource.resourceConfiguration.getSimpleValue('runtime-name', deploymentResource.name);

        var deploymentConfiguration = new Configuration;
        deploymentConfiguration.put(new PropertySimple('runtimeName', runtimeName));

        //so now we have both metadata and the data of the deployment, let's
        //push a copy of it to the target server
        var history = ResourceFactoryManager.createPackageBackedResource(targetAS7,
            deploymentResourceType.id, deploymentResource.name,
            deploymentResource.pluginConfiguration,
            installedPackage.packageVersion.generalPackage.name,
            installedPackage.packageVersion.version,
            installedPackage.packageVersion.architecture.id,
            deploymentConfiguration, content, null);

        while (history.status.name() == 'IN_PROGRESS') {
            java.lang.Thread.sleep(1000);
            //the API for checking the create histories is kinda weird..
            var histories = ResourceFactoryManager.findCreateChildResourceHistory(targetAS7, null, null, unlimitedPageControl);
            var hit = histories.iterator();
            var found = false;
            while(hit.hasNext()) {
                var h = hit.next();

                if (h.id == history.id) {
                    history = h;
                    found = true;
                    break;
                                           
                }
            }

            if (!found) {
                throw "The history object for the deployment seems to have disappeared, this is very strange.";
            }
        }

        println("Deployment finished with status: " + history.status.toString() +
            (history.status.name() == 'SUCCESS' ? "." : (", error message: " + history.errorMessage + ".")));
    }
}
