- 14. Cisco Systems Broadband Provisioning Register Runs on Berkeley DB Requirement : Cisco’s Broadband Provisioning Registrar (BPR) needed to manage up to 5 million networked devices and 150 configuration change transactions/second. BPR needed an embedded data manager which was fast, scalable, reliable and cost-effective. Solution : Berkeley DB was used to replace an object-oriented database in BPR. The result was faster, more reliable and saved Cisco $50,000/CPU. Cisco BPR Anton Okmianski, Senior Software Engineer, Cisco Systems “ When we switched to Berkeley DB we never looked back. It gave us high performance, small footprint and a set of well-targeted features that let us take our solution to a new level.”

Editor's Notes
- #8: Oracle Berkeley DB has a thriving Open Source community, a high download rate and over 200 Million deployed applications that use Berkeley DB, BDB XML or BDB Java Edition. You may not know it, but you probably use Oracle Berkeley DB every day. If you use Linux or Unix or access applications that run on those platforms, you are relying on Berkeley DB. If you use the Apache Web server or applications that use it, you are using Berkeley DB. Many open source scripting languages using Berkeley DB in some fashion. And this is only talking about the open source applications. In addition to all of these open source projects, you can add all of the OEM and ISV partner applications that embed Berkeley DB, like Cisco, Motorola, Alcatel, Mitel, Openwave, Critical Path etc. These applications are deeply embedded in the technology that underlies the infrastructure that we use every day. If you include enterprise applications that run NASDAQ, Google, Amazon, AOL, Starwood, etc. it is probable that you are using Berkeley DB many times during your day. XQilla was donated by the Oracle BDB XML team and integrate directly with BDB XML. The Internet Archive project uses Berkeley DB Java Edition to store and manage historical web page data
- #11: Berkeley DB is faster on INSERT/UPDATE/DELETE because it uses a Write Ahead Log. This allows BDB to only have to flush the appropriate log records to disk in order to insure ACID transactions. SQLite native uses a different logging implementation, which forces it to flush dirty cache pages AND log records, making it slower than BDB. SQLite does SELECTS pretty efficiently. There is very little that BDB can do to be more efficient. SQLite acquires and releases a single lock per table/database, where as BDB has to acquire and release a lock per page. The good news is that we’re more concurrent. The bad news is that we have to do more work than SQLite. In the worst case scenario (many random record lookups, based on a non-selective index) can cause BDB to be about 20-30% slower than SQLite.
- #12: Oracle Lite provides an end-to-end solution to enable developers to build, deploy and manage applications that need to access mission critical information in such a manner (i.e. in the field). Diagram At the heart of the Oracle Lite product is the Mobile Server component which provides two major functions: data synchronization a centralized console for managing all aspects of the distributed application deployment – deploying the application itself and updating its versions, managing the devices the application runs on in order to execute remote commands etc., managing the users who use the applications, and tuning data synchronization itself. At the edge of the network ( Embedded or Mobile Client ), the Oracle Lite client stack consists of a small footprint database, a synchronization client and a device management client. The database runs on client devices and provides a local relational store. The synchronization client can synchronize data with an Oracle RDBMS installation as well as application binaries via the Mobile Server. The Mobile Server Repository is simply an Oracle RDBMS installation in which Mobile Server can store it’s metadata that relates users, devices, applications, etc.
- #14: Reliability: Users often relax the ACID guarantees of SQLite in order to improve throughput by specifying PRAGMA synchronous=NORMAL or OFF. In this mode, the SQLite database can become corrupt if the application or system crashes. This is not the case with Berkeley DB. With Berkeley DB, transactions that have not been flushed to disk will be rolled back, but the database will be transactionaly consistent and database corruption will not occur.
