Deploying VDBs

A VDB is the primary means to define a Virtual Database in Teiid. A user can create a VDB using Teiid Designer - http://www.jboss.org/teiiddesigner/ - or follow the instructions in the Reference Guide to create a VDB without Teiid Designer.

Once you have a "VDB" built it can be deployed/undeployed in Teiid runtime in different ways.

Warning
If VDB versioning is not used to give distinct version numbers, overwriting a VDB of the same name will terminate all connections to the old VDB. It is recommended that VDB versioning be used for production systems.
Caution
Removing an existing VDB will immediately clean up VDB file resources, and will automatically terminate existing sessions.
Caution
The runtime names of deployed VDB artifacts must either be *.vdb for a zip file or *-vdb.xml for an xml file. Failure to name the deployment properly will result in a deployment failure as the Teiid subsystem will not know how to properly handle the artifact.

Direct File Deployment

Copy the VDB file into the

<jboss-install>/standalone/deployments

directory. Then create an empty marker file with same name as the VDB with extension ".dodeploy" in the same directory. For example, if your vdb name is "enterprise.vdb", then marker file name must be "enterprise.vdb.dodeploy". Make sure that there are no other VDB files with the same name. If a VDB already exists with the same name, then this VDB will be replaced with the new VDB. This is the simplest way to deploy a VDB. This is mostly designed for quick deployment during development, when the Teiid server is available locally on the developer’s machine.

Note
This only works in the Standalone mode. For Domain mode, you must use one of the other available methods.

Admin Console Deployment (Web)

Use the admin web console at:

http://<host>:<port>/console

More details for this can be found in the Admin Console VDB deployment section. This is the easiest way to deploy a VDB to a remote server.

CLI based Deployment

WildFly 10.0.0 provides command line interface (CLI) for doing any kind of administrative task. Execute

bin/jboss-cli.sh --connect

command and run

# in stand alone mode
deploy /path/to/my.vdb

# in domain mode
deploy /path/to/my.vdb --server-groups=main-server-group

to deploy the VDB. Note that in domain mode, you need to either select a particular "server-group" or all available server groups are deployment options. Check out CLI documentation for more general usage of the CLI.

AdminShell Deployment

Teiid provides a groovy based AdminShell scripting tool, which can be used to deploy a VDB. See the "deploy" method. Consult the AdminShell documentation for more information. Note that using the AdminShell scripting, you can automate deployment of artifacts in your environment. When using AdminShell, in domain mode, the VDB is deployed to all the available servers.

Admin API Deployment

The Admin API (look in org.teiid.adminpi.*) provides Java API methods that lets a user connect to a Teiid runtime and deploy a VDB. If you need to programatically deploy a VDB use this method. This method is preferable for OEM users, who are trying to extend the Teiid’s capabilities through their applications. When using Admin API, in domain mode, the VDB is deployed to all the servers.
