ASG-Rochade Ecosystem
Figure 1 on page 1 shows the Rochade architecture, which includes these components:
•
®
ASG-Rochade Server (herein called Rochade Server) and the Rochade repository
The Rochade repository provides a central point for collection, control,
management, and reuse of information assets. In turn, the Rochade Server provides
the connected Rochade components with access to the data in the repository.
•
APIs
—
®
ASG-Rochade Java API (herein called Java API/SRAP)
Java API is an object-oriented application programming interface (API)
available on all operating systems that support Java.
—
®
ASG-Rochade Information Retrieval (herein called Info Retrieval)
Info Retrieval searches and retrieves metadata from Rochade. The API also
can use Apache Solr to search an index of Rochade metadata.

System and Runtime Requirements
Rochade Server
ASG recommends these system resources for Rochade Server:
Rochade Server System Resources
Linux, UNIX, and
Windows
• RAM: At least 16 GB.
• Processors: One or more CPUs that, together, support multiple
concurrent threads at a clock rate of 2 GHz. Rochade Server can
utilize up to 43 processor cores.
• Disk capacity: 250 GB, including standard databases without user data.
z/OS
• Region size: 512 MB.
• Disk capacity: 250 GB, including standard databases without user data.
NOTE:
For z/OS, ASG provides only 32-bit modules of Rochade Server. For all other
supported operating systems, only 64-bit modules are provided.

ASG-Rochade Ecosystem
General Disk Properties
Rochade’s performance depends greatly on the data transfer rates of the storage system
you are using. Regardless of whether you are storing the Rochade databases on a local
hard disk, a disk array, or a storage area network (SAN), employing a disk controller with
a large cache (> 1 GB) can significantly improve performance.
ASG recommends that you only use disk controllers that have been designed for use
in data-critical transactional database systems. In particular, the disk controller must
guarantee that storage processes can be treated as complete as soon as the data have
reached the controller’s cache. The cache, therefore, must be protected against data
loss during power outages (e.g., by a backup battery). The controller can then continue
to write the cached data to the connected hard disks once the power has been restored.
The onboard caches of disk drives usually are not protected by a backup battery. These
caches, therefore, cannot guarantee to protect cached data during power outages. ASG,
therefore, recommends that you configure your storage system to disable the on-disk
cache and use the disk controller’s battery-backed cache instead.
