The XML Data Archiving Service (XML DAS) is part of a standard Application Server Java (AS Java) installation and can be used for archiving data both from Java and ABAP application systems.
The XML DAS comes with an administration tool called the XML DAS Administration.
An AS Java installatin contains the following for XML DAS:
The servlet /archtech/xmldasinitservice is responsible for creating User Management Engine (UME) roles and for initialising the MBeans.
Before you can begin XML DAS archiving you must set up the different components involved and configure your systems.

XML-based data archiving involves two systems that are logically, and usually also physically, separate.
During XML-based archiving the meta data and the property indexes used for value-based searches of archived data are stored in the database of the AS Java. The actual data that has been archived is stored in a storage system, which is connected to the AS Java. To configure your file or WebDAV system for XML DAS archiving, you use the XML DAS Administration, shown in the figure below.
You can reach the XML DAS Administration via the address http://<Host of J2EE Engine>:<HTTP port>/DataArchivingService/DAS
For example: http://localhost:50000/DataArchivingService/DAS
After you have set up your systems and made the archive stores available, you must use the XML DAS Administration to perform the following tasks:
The concept of an archive store is used to refer to a location (WebDAV collection or file system directory) within a storage system. Using the XML DAS Administration, you must first define archive stores to be able to test their availability. In case of WebDAV servers accessed via proxies, register the proxy for each archive store.

The XML DAS Connector of an application system provides a function to propagate new home paths to the XML DAS. Make sure that this function is executed so that XML DAS synchronizes the "known" home paths with new ones required by the applications.
SAP recommends that, if possible, you perform this necessary step from within the application system. This is because only here application-specific customizing can be taken into account.

Using the XML DAS Administration, you must assign an archive store to every home collection or application collection you want to use for archving.

In addition the XML DAS Administration offers the following features for packing and unpacking resources:

You can view the archive hierarchy, including details about the collections and resources in the hierarchy. You can also view all metadata managed by the data archiving service (XML DAS).
