Service API 3.0B – Zero Downtime Service
Zero-downtime during initial load / Early-delta initialization
In logistics, you can achieve zero-downtime during the initial load: data can already be written to the delta queue at the same time as data is transferred from the setup tables. A flag in the scheduler (as of 3.0A SP7) controls this feature.
Zero-downtime prior to and during initial load using a mirror source system
The Service API zero downtime service allows you to fill the setup tables in a mirror system, while posting continues in the original source system and and fills the Delta queue. After the setup tables have been filled and the initial load from the mirror system into the BW has been completed, the status information is synchronized with the original source system. Deltatransfer takes place from the original source system now into BW.

DB Connect (BW3.0B) - Scenario
Application
ORACLEDataBase
Purchasing
Unix
SAP BW
MS SQLDataBase
NTDB-Connect
A purchasing application runs on a legacy system based on an ORACLE database. To analyze the data from the purchasing application, the data needs to be loaded into the BW System (possibly installed on a different database, e.g. MS SQL-Server). DB-Connect can be used to connect the DBMS of of the purchasing application and extractdata from the tables or views.

� DB2 UDB
� DB2/400
� DB6
� Informix
� MS SQL Server 7.0 & MS SQL Server 2000
� Oracle 8.1.7.3+
� SAP DB

DB Connect - Prerequisites
� SAP BW 3.0B
� Table names and field names have to be in capital letters
� Usage of views on top of tables is recommended
� The SAP specific part of the database interface, the DBSL (database shared library) for the source DBMS, has to be installedon the application server. It can be downloaded from the SAP Service Marketplace. It is licensed and delivered to customers solely for use as part of the SAP BW.
� In some cases you need a Windows based AppServer, e.g. for source MS SQL
� The database specific DB-Client for the source DBMS has to be installed on the application server. It has to be licensed by the customer from the DB vendor and is delivered as part of the database access license .

Open Hub Pricing Issues
What the price list says about Open Hub:
„Open Hub has to be licensed whenever data is being extracted and transferred from mySAP BI into 3 rd party target systems. The communication between multiple SAP BW’s does not require Open Hub.“
Note: The term ‘Open Hub’ here has a broader scope, than the software functionality ‘Open Hub Service’
