I've starting to learn SQL and heavily interested in learning Oracle. I'm trying to download a version of Oracle to help with hands-on learning, and wondering if I should learn from the Express 18c version or 19c. I notice a lot of the courses on Udemy are Oracle Database is version 12c. I'm wondering if it matters? As far as I can tell the Oracle website does not allow a download of 12c anymore (though I might have just missed it), and Exam 1Z0-071 seems to be more conceptual of an exam. However, I'd like to make the best choice for future, more detailed and in-depth learning as well
I'd suggest 18c XE (or even 11gXE; it is still available). (You're right, 12c is unavailable.)
Express Edition (XE) is a good choice for students because it is easily installed and ready to go. As you don't plan to follow the DBA path (at least, that's how I understood what you said) and don't need to understand installation tricks in depth, something that installs in a matter of a few NEXT clicks is just a plus.
Alternatively, if you don't want to install anything, you can get a free account on apex.oracle.com. It is primarily used for Apex developers, but - you can still practice your (PL/)SQL skills in its SQL Workshop.

I have Oracle 11g R2 Free version in my laptop for development purpose, But i need to update the security patches given by Oracle. But while doing it it was taking me to a registration page where they are asking for Support Identifier.
Please help me out with this issue.
I'm not much into licencing, but - as far as I can tell - you get access to My Oracle Support (so that you could download patches, read additional documents, etc.) once you purchase (read: pay (a lot of) money) to Oracle because you started using their software in production.
For free versions, I'd say that you get quite a lot - regarding how much you paid for it (i.e. nothing at all), but shouldn't expect to get additional features as well.
If it is, as you said, for development purposes, why would you care about security patches? You don't trust yourself? :)
Therefore, in my opinion, you're out of luck.
How to convert an Oracle DB 11.2.0.3 to a 12cR2 PDB using Oracle Sqldeveloper?
As far as I can tell, you can't do that. SQL Developer does quite a lot of things, but I doubt that it is capable of upgrading a database version.
This is the Database Upgrade Guide (https://docs.oracle.com/database/121/UPGRD/toc.htm). Recommended method is Database Upgrade Assistant (DBUA), although you can do it manually. The question is: are you capable of doing it? I'm not implying that you're stupid, God forbid, but you might not have enough knowledge and/or experience. Perhaps you should discuss it with a proper DBA.
I'm planning to do an out-of-place upgrade for OBIEE from 10g on windows server 2003 to 11.1.1.9 on windows server 2012.
I find a document in the Oracle website below, which specify how to do an upgrade of OBIEE. However, may I know if it is applicable for an in-place update only? Could anyone please kindly recommend some useful references which specifies the steps required to perform an out-of-place upgrade as mentioned above?
Upgrade Guide for Oracle Business Intelligence 11g Release 1 (11.1.1.9.0) E16452-09
This tells you all you need: https://docs.oracle.com/middleware/11119/core/FUGBI/bi_plan.htm#FUGBI436
There's no such thing as an "in place" upgrade from 10g to 11g. The Upgrade Assistant helps with the RPD and WebCat, but you still need to do the manual migration. It's well documented and several years later a well-trodden path so you'll find plenty of blog posts etc discussing any issues you may encounter.
I used some reporting platforms ( SAP Business Objects and some other third party applications). I have pl-sql experience but I am new to Oracle BI.
At this point, I have some questions which confuses my mind.
First one is there are lots of terminology in Oracle BI but I do not know which products should I know, or in which order I can learn and experience these platforms.
For example you can create dashboards, analysis by Oracle BI. Terms/products like Essbase, Hyperion, Warehouse Builder, ODI etc.
My second question is :
I want to install Oracle 11g and Oracle BI 11 in the same pc. But I hearded and read on some forums that they are not working on the same computer. But I want to setup BI tool to my personal computer for practicing in my home. How can I install these two products in my pc? ( My pc is 64 bit)
Thanks&Regards
Just dot it ;-)

You can have a database and obiee on the same machine.

You need to install Oracle DB 11g followed by the latest OBIEE 11g installation. (note that you need to install RCU before you proceed with the OBIEE 11g install). You can get both of them from otn.oracle.com. The Install documentation can guide you in the entire setup; and hopefully there should be no surprises.
After that, install the Sample App and follow the instructions to create new analysis, dashboards etc. After this, am sure you will be upto speed with the terminologies and the workflows.
Check this post on wiki - should give you basic understanding on OBIEE stack
http://en.wikipedia.org/wiki/Oracle_Business_Intelligence_Suite_Enterprise_Edition
you mentioned Warehouse Builder - Oracle steering away from it, so ODI will be a choice of ETL tool.
You have a long journey ahead of you for OBIEE so, sit back, relax and enjoy the ride. You want to start with the BI Foundation which includes BI Server and Answers, before moving on to products like Essbase, Hyperion, Warehouse Builder, ODI etc.
I would start by
Doing a simple install of OBIEE. I prefer Linux but you can use Windows as well. 8GB would be nice. Each of the following has a graphical install wizard which guides you through the choices.
a. Install the DB
b. Run the RCU
c. Install OBIEE
d. Install BI Admin tool for creating or modifying the repository
Do some tutorials provided by Oracle. I would start with the following and in this order.
a. Creating a Repository Using the Oracle BI 11g Administration Tool - MANDATORY if you are a serious OBIEE professional
b. Creating Analyses and Building Dashboards - For Adhoc Analysis - Important
c. Getting Started with Oracle BI Publisher - OPTIONAL - If you care for published or printed reports or for some quick and dirty reporting, without having to create a model in the repository.
You want to avoid these common mistakes if you are installing on Windows.
You can install Oracle 11g ad Oracle BI in the same machine without any issue.
As far as the second question is concerned, you can create your reports with the knowledge of only Oracle BI , pl/sql and 11g. Pl/Sql is required to writhe pre and post procesors for the report. ESS will only be required to schedule the report and as such you won't require it in the learning phase. You can learn it later
I'm sorry that I have to ask that here, but I haven't found a conclusive answer on the oracle page or in the internet. I've even been on the phone with a sales rep, but they couldn't help me neither.
What kind of Oracle Setups/licenses are you using for your development environments? We currently are using 10g XE which only has one significant limitation: the 4gb database size limit. Are there any other 'free' versions which don't have such limitations? And if not, what would be the most economic version/combination? The often have a hard user limit which are ridiculous low.
Thanks!
Cheers

PS. I'm not sure if I have to mention that: I'm not looking for any illegal solutions
Since it appears that there exists a production environment, the license for the software you download from OTN will almost certainly not be sufficient. Since it sounds like each developer has a local development environment, however, you should be able to make use of the Personal Edition. This is a relatively inexpensive ($460 perpetual/ $92 for a 1-year license plus support in the Oracle Store at the moment) version of Oracle that is intended to be used by a single developer on a local machine. It has all the functionality of the enterprise edition of the database.
You can download Oracle Database 11g (and most other Oracle solutions) from their website oracle.com.
All you need is to register for free, and download the application, you don't need any license if it is for personal use.
