12th Day of #Cloud: Thoughts

12 Days of #Cloud: Day 12 After playing with Oracle Database Cloud Service (DBaaS) for past several days, I have mixed feeling. I like quite a lot of features and the amount of automation went into the product. For example, creating an RAC instance and creating a Data Guard instance by picking a check box […]

A Recipe for Summoning the RBO Monster (even in Oracle 12c): On Delete Cascade, Function-Based Index and Missing Table Statistics

The last version of Oracle in which CHOOSE was officially supported as an OPTIMIZER_MODE parameter value was 9.2.
This is what the documentation of Oracle 9.2 says about it:

choose
The optimizer chooses between a cost-based approach and a rule-based approach based on whether statistics are available.
If the data dictionary contains statistics for at least one of the accessed tables, then the optimizer uses a cost-based approach and optimizes with a goal (more...)

12 Days of #Cloud: Exploring #DBaaS with Data Guard

12 Days of #Cloud: Day 11 After a few failed attempts, I was successful in creating a Data Guard DBaaS Instance. Since I was playing with a trial account, the resources were limited. I guess when I had another database running, there is not much storage left to create two instances in Data Guard configuration. […]

Investigating IO performance on Amazon EC2

I published a blog post called “Investigating IO Performance on Amazon RDS for Oracle” recently, and soon after posting it I received several questions asking if IO worked the same way on EC2 instances. My immediate though was it did, mostly because RDS for Oracle is basically an EC2 instance with Oracle Database on top of it, where the configuration is fully managed by Amazon. But as always, it’s better to test than (more...)

Opening a web link from your MAF app in the device browser app

We've recently received a few inquiries about how to display a web link in a MAF app that will open in the device’s browser app when the user taps on it.

It seems that some teams have been relying on a side effect of whitelisting to circumvent the default MAF behaviour, which is to display the contents of the web link directly in the current WebView.  In earlier releases of MAF, if you did not (more...)

When local partitions….aren’t

Let’s say I’ve got a partitioned table, and because New Year’s eve is coming around, I certainly don’t want to be called out at 12:01am because I forgot to add the required partition for the upcoming year Smile.

SLOB 2.3 Data Loading Failed? Here’s a Quick Diagnosis Tip.

The upcoming SLOB 2.4 release will bring improved data loading error handling. While still using SLOB 2.3, users can suffer data loading failures that may appear–on the surface–to be difficult to diagnose.

Before I continue, I should point out that the most common data loading failure with SLOB in pre-2.4 releases is the concurrent data loading phase suffering lack of sort space in TEMP. To that end, here is an example of (more...)

NetBeans Git Client for JET Versioning and Oracle Developer Cloud Service

Fixing Popular Posts Margin on Blogger

Here is how I fixed it to display properly.
