I was able track down why I couldn’t connect to Oracle from Excel.
I had wanted to try some of the examples Charles Hooper has posted on connecting to and monitoring Oracle, for example
I kept getting the error “Provider not found”
Now what kind of trace info is there for an error like this in Excel? None AFAIK. Time to start guessing.
Delphix 4.1 just came out last week. It may sound only like a point release but there is an amazing amount of new technology:
I’m most excited about Amazon AWS support, Oracle 12c PDB support and developer jet pack , aka Jetstream. More coming on these features in upcoming blogs.
Want to advance your career ?
We’ve seen DBAs become managers, managers become directors, directors become VPs and CIOs go from lesser known companies to some of the best known in the world. Why did they get promoted? Because they brought in Delphix.
Delphix increases the speed, the agility of IT often enabling development teams to go twice as fast, an increase that is unprecedented.
Companies that have this advantage will outperform the competitors.
How do you (more...)
Uday Vallamsetty from Delphix performance group just posted a great blog post on evaluating I/O performance in Amazon AWS with EBS. I had a chance to talk with him a bit about I/O benchmarking and some of the surprises and challenges of I/O benchmarking as well as discuss the importance of producing a report card on any I/O subsystem one is using.
Delphix Engines expose all features via a stable WEB API built on top of HTTP and JSON.
Clients choose an HTTP client to interact with Delphix and integrate within their environment.
Delphix Engines are bundled with a command line interface which guides users for automation and integration with third party tools.
Delphix CLI example
Adding a SQL Server Source Environment:
Enter these commands through the command line interface:
How does Delphix benefit a SAP project?
- Speed up time to delivery for ASAP implementation methodology
- Enable adoption of “Continuous Application Delivery” methodology
- Reduce infrastructure overhead
- Deliver higher quality projects
ASAP methodology is a framework for delivering large IT projects. SAP professionals are familiar with this, however given the size and complexity of SAP projects, many fail to fully adopt it. Delphix helps customers adopt and use ASAP methodology.
SAP Projects today are big, hairy beasts. They (more...)
I use fio for all my I/O testing. Why not Orion from Oracle since almost all of my I/O testing and benchmarking has been geared toward Oracle? Several reasons
- super flexible – able to configure it for almost all types of test
- active community – updates almost every week, many by Jens Axobe (who wrote much of the Linux I/O layer)
- reliable – if there are problems, it’s open source and one can (more...)
Why did NoSQL arise? The rise of NoSQL makes no sense if you read an article like “Why You Should Never Use MongoDB” and the ycombinator replies . The I read something like this “Why You Should Use MongoDB” and don’t find any reasons just ranting about why the first article was shoddy.
One theory proposed by Martin Fowler is that NoSQL arose as a way to get (more...)
I’ve run into the wait “kksfbc child completion” a few times over the past but found very little written about it. I don’t have an explanation, but I have something that might be as good – a way to reproduce it. By being able to reproduce I at least test theories about it.
I ran a tight loop of
insert into t value(1);
See anything strange? I put “value” instead of “values” so the (more...)
