“Lift and Shift” On-Premise RPD to BI Cloud Service (BICS)

Introduction
“Lift and Shift” is the method by which an On-Premise RPD, created in the BI Admin tool, can be uploaded to a BI Cloud Service (BICS) instance and made available to report authors.
This cuts down on development time, allowing a single model to be used both on-premise, and in the cloud.  It also allows multiple subject areas to be created for a BICS reporting environment, accessible through the Visual Analyzer, and Answers reporting tools in BICS.
The process is simple, but has some minimum requirements:

WebLogic Server: Saving Disk Space in /tmp

Introduction
Many WebLogic Server (WLS) implementations use JRockit 28 as the JVM implementation. JRockit 28 comes with the very useful JRockit Flight Recorder which helps in many troubleshooting situations.
Problem
In high volume WLS implementations with many domains and many managed servers the Flight Recorder could fill up the disk of the temporary file storage (often located at /tmp). This works good for some time, but suddenly results in failures during restarts of some servers. It often helps to remove old and outdated data in the temporary file storage.

Should I use Oracle RAC for High Availability?

Almost all of my work involves high availability at one or more tiers, so options for Oracle Database resilience comes up regularly. Therefore I thought it would be worth writing down some of the considerations. 

5 Things I wish I knew about APEX when I just started (part 3)

In my previous post of this series, I talked about cookie sharing in APEX. The next post in this series is about build options, I hope you enjoy it.

Making OBIEE 11g Evaluate function dynamic

!function(d,s,id){var js,fjs=d.getElementsByTagName(s)[0],p=/^http:/.test(d.location)?'http':'https';if(!d.getElementById(id)){js=d.createElement(s);js.id=id;js.src=p+'://platform.twitter.com/widgets.js';fjs.parentNode.insertBefore(js,fjs);}}(document, 'script', 'twitter-wjs'); lang: en_US

EPM 11.1.2.x out of place maintenance release

The title of this post may seem a little strange as you are probably saying to yourself there is no out of place maintenance release and a maintenance release has to be applied to an existing 11.1.2.x deployment.

If you have a look at the 11.1.2.4 installation documentation you will see the rules behind a maintenance release.

5 Minute JavaScript #15: filter

In the previous blogpost we discussed the forEach method that iterates over every array. We can now create a filtered array by using this function.

var filtered = []
arr.forEach(function (item) { if (item.isOkay) filtered.push(item); });

While this will work fine, we still need to predefine our filtered array and push it in this array ourselves. We don’t need to… we could just use the filter method on the array prototype.

So What’s the Real Point of ODI12c for Big Data Generating Pig and Spark Mappings?

Oracle ODI12c for Big Data came out the other week, and my colleague Jérôme Françoisse put together an introductory post on the new features shortly after, covering ODI’s new ability to generate Pig and Spark transformations as well as the traditional Hive ones.

Setting up Security and Access Control on a Big Data Appliance

Like all Oracle Engineered Systems, Oracle’s field servicing and Advanced Customer Services (ACS) teams go on-site once a BDA has been sold to a customer and do the racking, installation and initial setup. They will usually ask the customer a set of questions such as “do you want to enable Kerberos authentication”, “what’s the range of IP addresses you want to use for each of the network interfaces”, “what password do you want to use” and so on.

Changing Environment Warning Color on WLS Console

  One of the rare mistakes in system configuring is when you actually thought you were in development or testing environment, but the browser actually pointed to production. You might even have the same credentials between the environment (e.g. linked to AD or LDAP directory), making it difficult to recognize the fatal error until it’s too late. When the consoles look alike there is nothing to differentiate from the other environments but you just have to be sharp to acknowledge were you are.
