SAP-Basis Interview questions

Not at all. On the contrary, SAP will continue to develop and support SAPDB to drive future enhancements in cooperation with the open-source community. Leveraging database technology is important for delivering comprehensive and innovative SAP components. Basis development in Berlin contributes to the Supply Chain Management/liveCache, Knowledge Management/Info DB, and SAPDB for SAP solutions among other tasks.

SAP DB's web-based problem tracking system can be used for bug reports and change reQuests.

At present, you are invited to send everything to the mailing list . Dependent on the amount of submissions, the contribution traffic may be moved to a separate mailing list or into the error tracking system.

No. Applications are using SAPDB as a service similar to the way they are using the operating system. The programming interfaces are released under the GNU LGPL (Library or Lesser General Public License). Software linked with the programming interfaces is not reQuired to be released as Open Source.

SAPDB is a state-of-the-art enterprise database system with a high level of performance, scalability, robustness and reliability. It is very easy to use and maintain, for example, no reorganization is reQuired and the database allows for uninterrupted 24x7 operation.
Thanks to its automatic, dynamic memory management, SAPDB also needs less disk space than other database systems such as Oracle or Informix. System resources do not reQuire constant attention.
All this, together with the fact that SAPDB is an open source solution, keeps total cost of ownership (TCO) at an all-time low compared to other database systems.

At the moment, no general summary is available. However, in terms of functionality and performance, SAPDB meets all the reQuirements needed to ensure smooth operation of all SAP solutions.

SAPDB currently supports Linux (Intel), Windows NT / Windows 2000 / Windows XP, IBM-AIX, SUN-Solaris, Tru64-Unix and HP-UX. OS/390, ZLinux and Microsoft .NET will also be supported in the near future.

Yes, but the 64-bit Linux and Intel ia64/Windows version are not yet available for productive use. We expect those during the first half of 2003.

ODBC (3.5.1), JDBC (2.0/3.0), C/C++ precompiler, and others.

None. Due to its fully automatic memory administration, SAPDB is completely reorganization free.

Yes. Using SAPDB, all necessary backup activities can be executed online.

ODBC is the official C-API. There is no performance loss because ODBC is not implemented as a wrapper around a lower level API. In UNIX, programmers can use either one of the available driver managers or link them directly with the libraries provided with SAP DB.

Backup and recovery are also part of our ease-of-use approach. The Database Manager, an SAPDB tool, offers intuitive backup scenarios and guides you through recovery processes. If you are running an SAP system with SAPDB, you can also schedule and execute your database administration tasks in the SAP Computing Center Management System (CCMS).

Yes, you can also use external backup tools. The Database Manager currently supports the following backup tools: TSM (IBM), Backint for Oracle, Backint for SAPDB, and NetWorker (Legato).
