Oracle, once again leading the pack has come up with a groundbreaking appliance and blogs are buzzing with it and so is this Log Buffer Edition. ODA and various sizzling news from SQL Server and MySQL are adorning this Log Buffer #239.
Sometimes clients ask us to implement scripts that change objects in their schemes. In order to prevent the situation when these scripts hung just because some, or several, objects are pinned. Here are two simple procedures that can help to check what we will get during our maintenance.
Today was a busy day in the news for Pythian, as Oracle released Oracle Database Appliance. Pythian is now offering fixed-price services to migrate to ODA and support it on an ongoing basis. Small and midsized business can leverage Pythian’s Oracle expertise and take full advantage of the cost and performance advantages of ODA.
I’m an experienced Oracle DBA, I have lots of Linux experience and scores of RAC installations under my belt. I also work for one of the best and more experienced RAC teams in the world. So when a customer asked how long it will take to install 2-node RAC, we answered “2 hours”. It took over 30 hours…
