Break free from vendor lock-in!
Are you sick of footing unbelievably large bills for Oracle licensing and looking for viable alternatives? You’re definitely not alone! There is good news… PostgreSQL is a very viable database alternative to Oracle and 2ndQuadrant is committed to supporting you through your migration from Oracle to PostgreSQL and beyond.
Contrary to popular belief, migrating from Oracle to PostgreSQL is only about as expensive as upgrading from one Oracle major version to the next. Both databases are ANSI compliant so lots of stuff just works on either database. For the remainder that doesn’t, we’ve got time-tested solutions which means reduced migration costs.
Tools we use for Migration from Oracle to PostgreSQL
Our efforts with our customers looking to migrate from Oracle to PostgreSQL are supplemented by powerful tools we have developed inhouse. We use these tools to seamlessly shift our customers to 100% open source PostgreSQL with no vendor lock-in. Making the process automated, these tools help speed up the migration efforts considerably.
PL/Translate – Translate PL/SQL to PL/pgSQL
PL/Translate is an advanced code translator for Oracle PL/SQL to Postgres PL/pgSQL (think ‘Google Translate’ for databases!), which is the missing part of the puzzle for quickly and cheaply migrating from Oracle to PostgreSQL. We believe in ‘code translation’ not ‘code emulation’.
ORQ – Replication from Oracle to PostgreSQL
Our efforts with our customers looking to migrate from Oracle to PostgreSQL are supplemented by powerful tools we have developed inhouse. We use these tools to seamlessly shift our customers to 100% open source PostgreSQL with no vendor lock-in. Making the process automated, these tools help speed up the migration efforts considerably.
Fastloader – COPY from Oracle to PostgreSQL
A PostgreSQL extension containing some Oracle connection functions. It includes an SQL function that allows you to specify all the same options as a COPY statement, as well as connection details to Oracle. Data is streamed back to PostgreSQL using OCI connection, at speeds of up to 2x the speed of the COPY command.

Steps involved in the Migration Process
The following steps are involved in a typical migration effort:
1- Initial Analysis
Before starting migration efforts, it is necessary to analyze, to the extent possible, the schema, data, and SQL code of the existing database to get an estimate of necessary effort. 2ndQuadrant has developed tools in-house for this type of analysis.
2- Migration
The actual migration largely consists of the implementation of the tasks determined during analysis; schema migration, data migration, SQL migration, Oracle equivalent functions, and application code changes.
3- Testing
In any migration effort, testing has fundamental importance. All workflows must be thoroughly tested against the newly migrated database. This includes workflows in the application layer as well as within the database. Fixing all bugs identified during testing is also part of the migration process.
4- Performance Tuning
Once all migration aspects are tested and settled, the new PostgreSQL database(s) need to be tuned to the client environment and usage patterns. 2ndQuadrant consultants provide personalized service for tuning a company’s database, customized to the organizational workloads.
5- Staff Training
Migrating from Oracle to PostgreSQL likely means staff is going to be exposed to a PostgreSQL backend database for the first time. Depending on the requirements of the company, 2ndQuadrant provides training to the organization’s staff, to enable them to handle their new PostgreSQL database.
6- Operations
Even experienced staff that handle PostgreSQL backend database on a day-to-day basis need assistance in handling complex issues. In such scenarios, 2ndQuadrant consultants help in the following areas:
- 24/7 break/fix support
- Backup & Recovery planning
- Replication setup
- High availability
