The ATG distribution provides two VFSs that can be configured for switch deployments:
/atg/epub/file/ConfigFileSystem/atg/epub/file/WWWFileSystem
ConfigFileSystem
The ATG distribution provides ConfigFileSystem with the Publishing agent. As installed, ConfigFileSystem is configured for online deployments. In order to deploy personalization and scenario assets to the target, you must configure ConfigFileSystem on each ATG server for switch deployments.
To configure each ConfigFileSystem VFS for switch deployments, perform these steps for each target ATG server:
Create an instance of
atg.vfs.switchable.SwitchableLocalFileSystem. The installation provides aConfigFileSystem.propertiesfile that you can copy from this location.<ATG10dir>/PublishingAgent/config/atg/epub/file/Uncomment the settings that are specific to switch deployment, and modify the properties where necessary. For more information about these properties, see SwitchableLocalFileSystem in Appendix B, Virtual File Systems.
Place the new
ConfigFileSystem.propertiesfile in each server’slocalconfigdirectory:../localconfig/atg/epub/file/For each server, add
ConfigFileSystemto the list of switchable data stores configured in theDeploymentAgent:../localconfig/atg/epub/DeploymentAgent.propertiesSet
switchableDataStoresto theConfigFileSystem’s fully qualified Nucleus path:/atg/epub/file/ConfigFileSystem
WWWFileSystem
The ATG distribution provides WWWFileSystem with the Publishing Web agent. As installed, it is configured for online deployments. If you install the Publishing Web agent on the target Web servers for deployment of deploy static text and binary files, you can configure the WWWFileSystem on each Web server for switch deployments.
To configure each WWWFileSystem VFS for switch deployments, perform these steps for each target Web server:
Create an instance of
atg.vfs.switchable.SwitchableLocalFileSystem . The installation provides aWWWFileSystem.propertiesfile that you can copy from this location.<ATG10dir>/PublishingWebAgent/config/atg/epub/file/Uncomment the settings that are specific to switch deployment, and modify the properties where necessary. For more information about these properties, see SwitchableLocalFileSystem in Appendix B, Virtual File Systems.
Place the new
WWWFileSystem.propertiesfile in each server’slocalconfigdirectory:../localconfig/atg/epub/file/For each server, add
WWWFileSystemto the list of switchable data stores configured in theDeploymentAgent:../localconfig/atg/epub/DeploymentAgent.propertiesSpecify
WWWFileSystemby its fully qualified Nucleus path:/atg/epub/file/WWWFileSystem
Configure VFSs on a New ATG server for Switch Deployment
When adding an ATG server or Web server to an existing target, configure its switchable VFSs like those on the existing ATG target servers. Verify that:
It has the same underlying data sources.
Its initial data store, specified in the
name1property of the VFS, is the same as their current data store, so the new server’s agent application starts up using the same data store.
