We are planning to install CA UIM in our environment with UIM Primary Hub as high available. Is there any document available to have UIM Primary Hub as high available mode.
Thanks & Regards,Shamseer
Search with "High Availability" and you'll find this one CA UIM v8.5.1 High Availability (HA) Guide
You need to install UIM and deploy the ha probe on your secondary hub.
You can also use the doc: Tech Tip: UIM & UMP HA setup and customization doc (version 0.11) if you want not only your primary hub in HA, but also switch your UMP server(s) to the new active UIM hub.
