  • Oracle & MySQL « Jnan Dash’s Weblog
    Now that Oracle will be the potential owner of MySQL, it will continue to offer it as the open source offering in database. It can position both Oracle and MySQL for different types of applications – Oracle for heavy lifting with high scalability (with its RAC) and complex functionality. It may even show a migration path for those MySQL users to Oracle deployment when needed.
  • SaaS and Cloud Stocks Up Nearly 50% In 2009
    We launched the index in 2008 — and it generated a dismal first-year performance, falling roughly 50 percent as the recession pulled down all companies, including SaaS providers. But 2009 has been a different story. Of the 20 index members, 19 have seen their shares rise. And all of those increases involve double-digit returns so far this year.
  • Amazon EC2 Shows Amazing Growth
    However, the most interesting aspect of Guy Rosen’s analysis is his calculation that 8.4 million EC2 instances have been launched since the launch of Amazon EC2. These are pretty big numbers showing success for cloud based computing. Kudos to Amazon for the success.
  • Anatomy of an Amazon EC2 Resource ID
    * 50,242 instances requested * 12,840 EBS volumes requested * 30,925 EBS snapshots requested * 41,121 reservations requested o Disambiguation: a reservation in this context is an atomic launch of one or more instances. This does not imply a reserved instance. For example, if you launch 1 instance, you get 1 instance ID and 1 reservation ID; if you launch 2 instances in one command, you get 2 instance IDs and still 1 reservation ID. These numbers are impressive, to say the least. Even more impressive is a small hint, lurking between the numbers, that implies that just over the past month Amazon crossed a significant threshold (see below for more details): 8.4 million EC2 instances launched (since EC2’s debut).
  • In-Memory Parallel Execution in Oracle Database 11gR2
    In-Memory Parallel Execution (In-Memory PX) takes advantage of these larger buffer caches but it also ensures we don’t trash the cache. In-Memory PX begins by determining if the working set (group of database blocks) necessary for a query fits into the aggregated buffer cache of the system. If the working set does not fit then the objects will be accessed via direct path IO just as they were before. If the working set fits into the aggregated buffer cache then the blocks will be distributed among the nodes and the blocks will be affinitzed or associated with that node. In previous releases, if the Parallel Execution of one statement read part of an object into the buffer cache, then subsequent SQL statement on other nodes in the cluster would access that data via Cache Fusion. This behavior could eventually result in a full copy of that table in every buffer cache in the cluster. In-Memory PX is notably different because Cache Fusion will not be used to copy the data from its origina

  • Google endows $2.5M Rajeev Motwani chair
    “The breadth and depth of Rajeev’s contributions in academia and industry are unparalleled in computer science. Yet they pale in comparison to the impact he had through the many researchers and entrepreneurs whom he taught and mentored,” said Brin, Google‘s president for technology. “While I am sad to lose a good friend, I know his spirit will live on through generations of technologies and technologists to come.” [Really, unparalleled?
