1 Prerequisites
Ensure that you go through the following prerequisites before using Oracle GoldenGate on Oracle Cloud Marketplace.
Supported Browsers
Oracle Cloud Infrastructure supports the latest desktop versions of Google Chrome, Microsoft Edge, Internet Explorer 11, Safari, Firefox, and Firefox ESR. Note that Mobile browsers as well as private browsing mode is not supported for Firefox, Internet Explorer, or Edge.
1.1 Prerequisites to Deploy Oracle GoldenGate Microservices
By using Oracle GoldenGate Microservices on Marketplace, you can deploy Oracle GoldenGate in an off-box architecture, which means you can run and manage your Oracle GoldenGate deployment from a single location.
Here are the prerequisites required to deploy Oracle GoldenGate Microservices:
- Oracle Cloud Account
- Access to assigned Oracle Cloud Tenant
- Compute node resources within Oracle Cloud Tenant
- Local SSH/RSA Key
Create an SSH/RSA Key
To work with the Oracle Cloud Infrastructure once the Oracle GoldenGate Compute Node is built, you have to provide a SSH Public Key during the interview process that will allow you to log in to the node once built.
In order to build your SSH keys, perform the following steps:
- Open a Terminal window and start the
key generation program by typing the following
command:
$ ssh-keygen Generating public/private rsa key pair. - Enter the path to store this file.
By default, this gets saved in your home directory
under a hidden folder called
.ssh. Change this default location, if required.Enter file in which to save the key (/Users/johndoe/.ssh/id_rsa): <Return> - Enter a passphrase for using your
key.
Enter passphrase (empty for no passphrase): <passphrase> - Re-enter the passphrase to confirm
it.
Enter same passphrase again: <passphrase> - Check the results.
The key fingerprint (a colon separated series of 2 digit hexadecimal values) is displayed. Check if the path to the key is correct. In the above example, the path is
/Users/johndoe/.ssh/id_rsa.pub. You have now created a public or private key pair.
Note:
For generating key pair on Windows platform, refer to Creating a Key Pair section in Oracle Cloud Infrastructure Documentation.Parent topic: Prerequisites
1.2 OCI Policies Needed for Creating Oracle GoldenGate Marketplace Instances
The following OCI policies are required for creating Oracle GoldenGate Market Place instances:
- Allow group <ggowner> to manage instance-family in compartment <Compartment Name>
- Allow group <ggowner> to manage orm-family in compartment <Compartment Name>
- Allow group <ggowner> to manage volume-family in compartment <Compartment Name>
- Allow group <ggowner> to use virtual-network-family in compartment <Compartment Name>
- Allow group <ggowner> to manage public-ips in compartment <Compartment Name>
- Allow group <ggowner> to use tag-namespaces in tenancy
- Allow group <ggowner> to inspect compartments in tenancy
Where <ggowner> is an example for a group and <Compartment Name> is an example of a compartment. The following are permission names: instance-family, orm-family, volume-family, virtual-network-family, and public-ips.
Note:
- The manage public-ips permission is required only if you give the instance a public IP address. Oracle GoldenGate uses reserved IP addresses so that the public address is preserved across stack upgrades.
- The Networks compartment is an assumption that the customers
follow the practice of having a separate network group manage the network
resources for all users in the tenancy. If the tenancy instead allows you to
create network resources of your own, then the policy would be:
Allow group <marketplace-permissions> to manage virtual-network-family in compartment <Marketplace-Test>.
