Performance Metric Service – Classic Configuration

Almost a year ago, Oracle released Oracle GoldenGate 12c ( At that time, there were two architectures released; Microservices and Classic. Both architectures provided the same enterprise level replication. The only difference was that one enabled a RESTful API interface with HTML5 page and the other was still command line driven.

The biggest change though was with the addition of the Performance Metric Service/Server that come bundled with the core product. (more...)

Loading Tables with Oracle GoldenGate and REST APIs

With Oracle GoldenGate 12c (, you can now quickly load empty target tables with data from your source database. You could always do this in previous releases of Oracle GoldenGate, but the process has now been simplified using REST APIs and some scripting know-how. In this post, I’m going to show you, high level, how you can use the REST APIs and a bit of scripting to do an initial load (more...)

Build a Integrated Replicat using JSON

In a previous post, I showed you how to build an Integrated Extract (IE) and Distribution Path by using JSON and cURL. In this post, let’s look at how you can build an Integrated Replicat (IR) in the same manner.

To build a replicat using JSON, the JSON document is made up of the following 8:

Config – Details for the associated parameter file
Source – Where the replicat should read transactions from
Credentials – (more...)

Build a Distribution Path using JSON

In a previous post, I showed you how to build an Integrated Extract (IE) using JSON and simple cURL command. In this post, let’s take a look at how to build a Distribution Service Path.

First think to understand is that the Distribution Service is the replace for the Extract Data Pump in the traditional Oracle GoldenGate architecture. The Distribution Service does the same thing as the Extract Data Pump with the exception of transformations. (more...)

Build an Integrated Extract using JSON

Now that Oracle GoldenGate 12.3 Microservices have been out for about 9 month; there seems to be more and more discussions around how microservices can be used. The mircoservices architecture provides a faster way for users to build extract, replicats, distribution paths and many other items by using a JSON document and simply calling a REST end-point.

In this post, I’ll show you how to build an integrated extract using JSON and REST APIs. (more...)

How to write to SYSLOG in OGG 12.3 Classic and Microservices Architectures?

Oracle GoldenGate 12.3 Microservices introduced a lot of changes into how replication is to be managed moving forward. The Microservices Architecture (MA), provides a lot of opportunity for people to learn a lot about microservices and how they can be leveraged to to bring real-time replication to their organizations.

One feature that was used in the Classic Architecture (CA) was having the GGSERR.log file write items to the messages file at the system (more...)

Changing Security Role Password in Oracle GoldenGate 12.3 Microservices

One of the nice things about Oracle GoldenGate 12.3 Microserivces, is the flexibility we now have to interact with Oracle GoldenGate. Additionally, what comes with Oracle GoldenGate 12.3 Microservices is a new role based security frame work.

When you first setup Oracle GoldenGate 12.3 Microservices, you setup your ServiceManager and initial deployment. Upon setting this up, you will assign a new administrator to the frame work. This is a different user than (more...)

Identifying Integrated Replicat transactional progress

From time-to-time, you may want to find out what transactions have been applied or still in flight while Oracle GoldenGate is running while using the Integrated Replicat (IR) products. This can be done easily by using the ALL_GG_INBOUND_PROGRESS/DB_GG_INBOUND_PROCESS views. There are a few columns of interest in this view, they are:

  • APPLIED_LOW_SCN (not applicable for GoldenGate)

Note: For more information on this view, reference Oracle Docs – here

The APPLIED_LOW_POSITION represents the (more...)

Start/Stop Extract/Replicat with REST API/JSON

Oracle GoldenGate Microservices Architecture is designed to allow the user to have three different ways of interacting with replication from anywhere. One of these approaches is to use the RESTful APIs that come bundled with release. By using RESTful APIs, an organization can orgistrate how they want GoldenGate to work within their environment.

In this post, you will take a look at how to start a pre-existing extract/replicat by using the RESTful API end points. (more...)

Linking Oracle GoldenGate Classic Architecture to Oracle GoldenGate Microservices Architecture

In my last post I covered how to connect the microservices architecture to the classic architecture (here). For this post, I want to show you how to connect the GoldenGate Classic Architecture to the new GoldenGate Microservices Architecture.

You many be asking yourself, why do I want to do this? The answer is quite simple. At the current moment and time, there is no upgrade path to move from Classic to Microservices. This (more...)
