In this post we continue exploring the technical aspects of Oracle to PostgreSQL migration using AWS SCT. We were using AWS SCT build#660 to convert one of our Oracle test databases. AWS SCT provides functionalities for the most efficient migration from Oracle to PostgreSQL. However, there is a common challenge with implementing the Oracle NumToDSInterval function in PostgreSQL. The Oracle NumToDSInterval function is responsible for the conversion of the provided number value of specified time units or expressions to an […]

In this post we continue exploring the technical aspects of Oracle to PostgreSQL migration using AWS SCT. AWS SCT promises a very high level of migration efforts, however it is very rare that 100% automation is achieved. In this article we’ll look into conversion of INSERT ALL statements, which are quite popular in Oracle code. We were using AWS SCT build #660 to convert one of our Oracle test databases. Oracle gives you an option to use the conditional insert […]

In this post we explore the technical aspects of Oracle to PostgreSQL migration using AWS SCT. We’ll look into conversion of Oracle “aliases”. We were using AWS SCT build #660 to convert one of our Oracle test databases. The challenge Oracle’s subtype declaration allows creating an “alias” for some datatype declaration, which can be re-used later as many times as needed. PostgreSQL domains entirely differ from Oracle’s subtypes. Thus, whenever you try to convert PL/SQL code containing variables that are […]

One of the world’s largest distributors of non-food consumable products wanted to rationalize their data platform and business intelligence strategy. Their current IBM DB2 database system lacked a repository to host historical audit-related data, so they could hardly retrieve data from past years.
