CDC Oracle is not CDC Amazon
I have done some migrations from Oracle On-premise to Oracle AWS RDS using the AWS DMS (Data Migration Services) . However, while I was giving a lecture in Sweden I found out that the CDC is not supported in Oracle 12 and onward. Mathias Magnusson, one of the Oracle Aces (Oracle Ace Program) in Sweden asked me if the Amazon CDC mentioned in my presentation was the same CDC in the Oracle Database. At that moment I didn’t have the information but after the presentation and some research I found…

Changing default PGDATA for PostgreSQL 9.5 in RedHat 7
By default Red Hat and Centos OS stores the database in the file system /var/lib/pgsql/data/. The area where the database is located can be changed depending on individual environment requirements or preferences. So to speak, in this post I will show how to change this location. First, let’s check the current location of the PostgreSQL using the command “SHOW data_directory;” inside one of the databases. You can see in the example above that the location of the database files are the default location for RedHat which is “/var/lib/pgsql/9.5/data “. So…

When use Temporary Tablespace Groups
I was managing a database that had a temporary tablespace which was having problems to hold the results of a sort. Then I solved this problem by creating a temporary tablespace group. And according to Oracle Corporation, “… enables parallel execution servers in a single parallel operation to use multiple temporary tablespaces.”. So how can I do that? If you are managing a multitenant database you must have in mind what problem is occurring in one of your PDB or the CDB. Let’s see if we are going to create…
