Ubuntu 22.04

RHEL 8.0-8.8 or 9.0-9.2

For Ubuntu, it must be:

• Ubuntu Server 22.04 (and not Ubuntu Minimal)
• A dedicated Ubuntu Server machine (and not Ubuntu Desktop)

For RHEL, we recommend RHEL raw images. RHEL LVM will also work but may require additional configuration of the OS disk (described in the next step).

The user running the installation will need to be root or have sudo access to the machine.

The memory defines how many data containers can be hosted in parallel & how many storage disks can be attached.

For a first proof of concept (POC) we recommend starting with 16GB. This will allow for a single data-image and several data-containers to be created and run in parallel.

You will need to increase RAM as you start working with more data-images and data-containers. Please see the Database Engines Support page to learn more about the default settings for each database engine.

Please also see the following FAQs:

• How much RAM does a data image consume and for how long?
• How much RAM does a data container consume and for how long?

100GB (See notes)

Valid (public or private) DNS Name (FQDN (Fully  Qualified  Domain  Name))

This will need to be a CNAME record that redirects to the Virtual Machine running the Redgate Clone. 

DNS name, which is resolvable publicly, or in your company's network, simplifies Using the CLI usage for your employees, and also allows us to use TLS certificate to secure comms.

You will need a  TLS Certificate  (i.e.  my-certificate.crt) and a  TLS Key  (i.e.  my-certificate.key) files.

• TLS Certificate  - The PEM file containing the TLS certificate. The PEM file should contain the certificate itself along with any required intermediate certificates. The file should have this format:

  -----BEGIN CERTIFICATE-----
  certificate 1
  -----END CERTIFICATE-----
  -----BEGIN CERTIFICATE-----
  certificate 2
  -----END CERTIFICATE-----
  ...

  
  

• TLS Key  - The PEM file containing the TLS key. The file should have this format:

  -----BEGIN PRIVATE KEY-----
  private key
  -----END PRIVATE KEY-----

The following kernel configuration values should be set:

• fs.aio-max-nr should be at least 1048576.
• fs.inotify.max_user_instances should be at least 512.

The typical default values for these configuration options has been known to result in errors during pod creation. See the following troubleshooting articles for more information:

• "Too many open files"
• Insufficient async disk I/O kernel resources

You will need an application license that can be downloaded using the URL and the password provided as a part of the onboarding process.  You must accept and provide a license to proceed with the installation of Redgate Clone.
