I got a new ( and possibly new-fangled) phone recently.
Having spent a suitably geeky amount of time exploring the new features of this slab of Android lovliness I did come across something which left me quite stumped… somebody rang me up on it.
Increasingly frantic tapping of the little green phone icon failed to result in me answering the call.
It was at this point that Deb took pity and explained in that ever-so-patient way people use to the hard of thinking, that I simply needed to swipe.
Imagine this: it’s been a productive WordPress weekend. You’ve been busy puttering away on the new website you put together for your cat-lovers’ club and you’re pleased with the progress so far.
You found an adorable kitty-friendly theme, snagged a memorable site address, added some snazzy widgets in all the right places, and you’re finally ready to introduce your baby to the world.
But, wait! Just before making the site public, you notice that the header isn’t displaying your site title and tagline along with the header graphic.
Windows-On-Windows 64-bit (WOW64) enables you to run 32bits applications in 64bits OS.
You will see there is another powershell, another registry, another ODBC tool, another Oracle client.
First, we run powershell(x86)
Here’s a little quiz: If I take the average row length of the rows in a table, multiply by the number of rows, and convert the result to the equivalent number of blocks, how can the total volume of data in the table be greater than the total number of blocks below the table high water mark ? I’ve got three tables in a schema, and they’re all in the same (8KB block, 1M uniform extent, locally managed) tablespace, but here’s a query, with results, showing their space utilisation – notice that I gather schema stats immediately before running my query:
[I]select * from students
where student_id in (' ', ' ',..... ' '_;[/I]

Let us have a look at the Provisioning and Patching feature in OEM 12c.
We have a ‘gold image’ of a 22.214.171.124 Oracle Database Software where the Jan 2013 PSU has been installed.
We now want to deploy this particular 126.96.36.199 version of the database software on a number of target hosts.
Note – the deployment procedure outlined below assumes that the 12c management agent has been installed on the target hosts and the Software Library has been setup and configured in OEM 12c.
An Oracle white paper on this subject has recently been released.
Fine Grained Access Control aka Virtual Private Database (VPD) has been there since Oracle 8 and got enhanced in each subsequent version. One minor New Feature of 11.2 was the addition of the parameter UPDATE_CHECK to the DBMS_RLS.ADD_POLICY procedure.
Lately I have been drawn into to a fare number of discussions about IO characteristics while helping customers run benchmarks. I have been working with a mix of developers, DBAs, sysadmin, and storage admins. As I have learned, every group has there own perspective – certainly when it comes to IO and performance.
