Connecting to Oracle Database using cx_Oracle module 7 for Python
In this post I will simply show how to connect to an Oracle database using Python 3 in an Oracle Linux 7.6 OS. One of the things that you have to do is to install Python in your OS. By default, Oracle Linux 7.6 comes with Python 7.6 but from 7.7 ownwards it comes with the version Python 3. If you wish to install the Python 3 in your system I do recommend you to take a look at one of my blog posts about this topic: “Installing Python 3…
Installing Python 3 on Oracle Linux 7.6
There are several ways to install python 3 on Oracle Linux 7 systems. You can either perform an installation using an EPEL (Extra Packages for Enterprise Linux) repository or the Software Collection Library (SCL) which requires that you perform other types of commands. However, on this post I am going to install from the the Oracle Linux 7 latest repository which is also another method besides the two previously mentioned. Also the OS will be an Oracle Linux 7.6 that comes installed by default, the version 2.7 of Python is…
Oracle 12cR1: Moving tablespace by using the transportable tablespace feature from a Solaris Operating System (x86-64) to a Linux x86 64-bit system
This post will be about Cross-platform transportable tablespace. Cross-platform transportable tablespace is a technique where you can copy a tablespace from a database running in one platform to another platform. Also Cross-platform transportable tablespace isn’t the same as Cross-platform transportable database. In this instance the whole database is copied including the SYSTEM tablespace. In this post we are going to copy a tablespace from one database to another database. Then the first thing you have to know is the internal names for each platform that supports cross-platform data transport and…

Digging the STAR_TRANSFORMATION_ENABLED parameter on Oracle database 12cR1 inside a PDB
When you think of a parameter that can help you out with star queries, this parameter is the STAR_TRANSFORMATION_ENABLED. According to the Oracle official documentation, it is described as the difference between a typical query and a star query, “A typical query in the access layer is a bond between the fact table and some number of dimension tables and is often referred to as a star query. In a star query, each dimension table is joined to the fact table using a primary key to foreign key join. Normally…
Taking an Oracle exam in unusual times – Nothing like a day (or months) like the other – Oracle Autonomous Database Cloud 2019 Specialist 1Z0- 931
My interest in the Oracle Autonomous Database Cloud 2019 certification started in September 2019 when I took this exam while attending the OOW19 (Oracle Open World 2019) at San Francisco, California, USA. Back then I failed the exam for many reasons, lack of studying (what matters a lot), pressure and so on but I am not here to make excuses because it would not change the results. So since then, I was involved in more projects where I could not only work with Oracle but also with Amazon Cloud and…

These files are created in a directory at a local or remote server and if you desire to copy them you have to tape library. However, PostgreSQL database isn’t created with the WAL option enabled and to be able to use it you have to configure some essential parameters in the postgresql.conf file. Therefore , these parameters are: archive_command: Here is the directory that you want your WAL files be stored in. You can…
