Implement Oracle Golden Gate on an Azure Linux virtual machine (VM)

  • Article

Applies to: ✔️ Linux VMs

The Azure CLI is used to create and manage Azure resources from the command line or in scripts. This guide details how to use the Azure CLI to deploy an Oracle 19c database from the Azure Marketplace gallery image.

This document shows you step-by-step how to create, install, and configure Oracle Golden Gate on an Azure VM. In this tutorial, two virtual machines are set up in an availability set in a single region. The same tutorial can be used to set up OracleGolden Gate for VMs in different Availability Zones in a single Azure region or for VMs set up in two different regions.

Before you start, make sure that the Azure CLI is installed. For more information, see Azure CLI installation guide.

Introduction

GoldenGate is a logical replication software that enables real-time replication, filtering, and transformation of data from a source database to a target database. This feature ensures that changes in the source database are replicated in real-time, making it possible for the target database to be up-to-date with the latest data.

Use GoldenGate mainly for heterogeneous replication cases, such as replicating data from different source databases to a single database. For example, a data warehouse. You can also use it for cross-platform migrations, such as from SPARC and AIX to Linux x86 environments, and advanced high availability and scalability scenarios.

Additionally, GoldenGate is also suitable for near-zero downtime migrations since it supports online migrations with minimal disruption to the source systems.

While GoldenGate facilitates bi-directional replication, the application must be configured accordingly. Additionally, the software permits filtering and transformation of data to meet specific business requirements, enabling users to make use of the replicated data for various purposes.

Prepare the environment

To perform the Oracle Golden Gate installation, you need to create two Azure VMs on the same availability set. The Marketplace image you use to create the VMs is Oracle:oracle-database-19-3:oracle-database-19-0904:19.3.1.

You also need to be familiar with Unix editor vi and have a basic understanding of X Server.

The following table is a summary of the environment configuration:

Primary site Replicate site
Oracle release Oracle Database 19.3.1.0 Oracle Database 19.3.1.0
Machine name ggVM1 ggVM2
Operating system Oracle Linux 7.x Oracle Linux 7.x
Oracle SID CDB1 CDB1
Replication schema TEST TEST
Golden Gate owner/replicate C##GGADMIN REPUSER
Golden Gate process EXTORA REPORA

Sign in to Azure

  1. Open your preferred shell on Windows, Linux, or Azure Shell.

  2. Sign in to your Azure subscription with the az login command. Then follow the on-screen directions.

    $ az login

  3. Ensure you're connected to the correct subscription by verifying subscription name and/or ID.

    $ az account show

    {
  "environmentName": "XXXXX",
  "homeTenantId": "XXXXXXXX-XXXX-XXXX-XXXX-XXXXXXXXXXXX",
  "id": "<SUBSCRIPTION_ID>",
  "isDefault": true,
  "managedByTenants": [],
  "name": "<SUBSCRIPTION_NAME>",
  "state": "Enabled",
  "tenantId": XXXXXXXX-XXXX-XXXX-XXXX-XXXXXXXXXXXX",
  "user": {
    "cloudShellID": true,
    "name": "aaaaa@bbbbb.com",
    "type": "user"
  }
}

Generate authentication keys

We use key file based authentication with ssh to connect to the Oracle Database VM. Ensure that you have your private (named id_rsa) and public (named id_rsa.pub) key files are created on your shell.

Location of key files depends on your source system.

Windows: %USERPROFILE%.ssh Linux: ~/.ssh

If they don't exist, you can create a new keyfile pair.

ssh-keygen -m PEM -t rsa -b 4096

The .ssh directory and key files are created. For more information, see Create and manage SSH keys for authentication to a Linux VM in Azure

Create a resource group

To create a resource group, use the az group create command. An Azure resource group is a logical container in which Azure resources are deployed and managed.

$ az group create --name GoldenGateOnAzureLab --location westus

Create and configure network

Create virtual network

Use following command to create the virtual network that hosts resources we create in this lab.

$ az network vnet create \
  --name ggVnet \
  --resource-group GoldenGateOnAzureLab \
  --address-prefixes "10.0.0.0/16" \
  --subnet-name ggSubnet1 \
  --subnet-prefixes "10.0.0.0/24"

Create a Network Security Group (NSG)

  1. Create a network security group (NSG) to lock down your virtual network.

    $ az network nsg create \
  --resource-group GoldenGateOnAzureLab \
  --name ggVnetNSG

  2. Create NSG rule to allow communication within virtual network.

    $ az network nsg rule create  --resource-group GoldenGateOnAzureLab --nsg-name ggVnetNSG \
    --name ggAllowVnet \
    --protocol '*' --direction inbound --priority 3400 \
    --source-address-prefix 'VirtualNetwork' --source-port-range '*' \
    --destination-address-prefix 'VirtualNetwork' --destination-port-range '*' --access allow

  3. Create NSG rule to deny all inbound connections.

    $ az network nsg rule create \
  --resource-group GoldenGateOnAzureLab \
  --nsg-name ggVnetNSG \
  --name ggDenyAllInBound \
  --protocol '*' --direction inbound --priority 3500 \
  --source-address-prefix '*' --source-port-range '*' \
  --destination-address-prefix '*' --destination-port-range '*' --access deny

  4. Assign NSG to Subnet where we host our servers.

    $ az network vnet subnet update --resource-group GoldenGateOnAzureLab --vnet-name ggVNet --name ggSubnet1 --network-security-group ggVnetNSG

Create Bastion Network

  1. Create Bastion subnet. Name of the subnet must be AzureBastionSubnet.

    $ az network vnet subnet create  \
    --resource-group GoldenGateOnAzureLab \
    --name AzureBastionSubnet \
    --vnet-name ggVnet \
    --address-prefixes 10.0.1.0/24

  2. Create public IP for Bastion.

    $ az network public-ip create \
    --resource-group GoldenGateOnAzureLab \
    --name ggBastionIP \
    --sku Standard

  3. Create Azure Bastion resource. It takes about 10 minutes for the resource to deploy.

    $ az network bastion create \
    --resource-group GoldenGateOnAzureLab \
    --name ggBastion \
    --public-ip-address ggBastionIP \
    --vnet-name ggVnet \
    --sku Standard \
    --enable-tunneling \
    --enable-ip-connect true

Create X Server VM (ggXServer)

Replace your password and run the following command to create a Windows workstation VM where we deploy X Server.

$ az vm create \
     --resource-group GoldenGateOnAzureLab \
     --name ggXServer \
     --image MicrosoftWindowsDesktop:Windows-10:win10-22h2-pro-g2:19045.2604.230207 \
     --size Standard_DS1_v2  \
     --vnet-name ggVnet \
     --subnet ggSubnet1 \
     --public-ip-sku Standard \
     --nsg "" \
     --data-disk-delete-option Delete \
     --os-disk-delete-option Delete \
     --nic-delete-option Delete \
     --admin-username azureuser \
     --admin-password <ENTER_YOUR_PASSWORD_HERE>

Connect to ggXServer through Bastion

Connect to ggXServer using Bastion.

  1. Navigate to ggXServer from Azure portal
  2. Locate Overview in the left navigation
  3. Select Connect > Bastion on the menu at the top
  4. Select Bastion tab
  5. Click Use Bastion

Prepare ggXServer to run X Server

X Server is required for later steps of this lab. Perform following steps to install and start X Server.

  1. Download Xming X Server for Windows to ggXServer and install with all default options.

  2. Ensure that you didn't select Launch at the end of installation

  3. Launch "XLAUNCH" application from start menu.

  4. Select Multiple Windows

    Screenshot of XLaunch wizard step 1.

  5. Select Start no client

    Screenshot of XLaunch wizard step 2.

  6. Select No access control

    Screenshot of XLaunch wizard step 3.

  7. Select Allow Access to allow X Server through Windows Firewall

    Screenshot of XLaunch wizard step 4.

If you restart your ggXServer VM, follow steps 2-6 above to restart X Server application.

Create Oracle database virtual machines

For this lab, we create virtual machines ggVM1 and ggVM2 from Oracle Database 19c image. If they don't already exist in the default key location, this command also creates SSH keys. To use a specific set of keys, use the --ssh-key-value option. If you already created your SSH keys in Generate authentication keys section, those keys are used.

When you create a new virtual machine, the size parameter indicates the size and type of virtual machine created. Depending on the Azure region you selected to create virtual machine and your subscription settings, some virtual machine sizes and types may not be available for you to use. The following example uses minimum required size for this lab Standard_DS1_v2. If you want to change specs of virtual machine, select one of the available sizes from Azure VM Sizes. For test purposes, you can choose from General Purpose (D-Series) virtual machine types. For production or pilot deployments, Memory Optimized (E-Series and M-Series) are more suitable.

Set up replication (ggVM1 and ggVM2)

1. Set up the replication on ggVM2 (replicate)

Sign in to ggsci.

$ cd /u01/app/oracle/product/12.1.0/oggcore_1
$ ./ggsci

GGSCI> EDIT PARAMS MGR

Update the file with the following.

PORT 7809
ACCESSRULE, PROG *, IPADDR *, ALLOW

Restart the Manager service.

GGSCI> STOP MGR
GGSCI> START MGR
GGSCI> EXIT

2. Set up the replication on ggVM1 (primary)

Start the initial load and check for errors.

$ cd /u01/app/oracle/product/19.0.0/oggcore_1
$ ./ggsci

GGSCI> START EXTRACT INITEXT
GGSCI> VIEW REPORT INITEXT

3. Set up the replication on ggVM2 (replicate)

Change the SCN number with the number you obtained before.

$ cd /u01/app/oracle/product/19.0.0/oggcore_1
$ ./ggsci

START REPLICAT REPORA, AFTERCSN 2172191
