Updating OS (Azure)

Note: Running yum update without first stopping Oracle and FlashGrid services may result in the services restarting non-gracefully during the update.

To update OS on a running server perform the following steps

1. Create backup snapshot of the OS disk

   a. Flush OS buffers:

   # sync

   b. Create snapshot of the OS disk using Azure portal or CLI

2. Stop all running databases.

3. Stop Oracle High Availability Services:

   # crsctl stop has

4. Stop FlashGrid Storage Fabric services:

   # flashgrid-node stop

5. Install OS updates:

   # yum update

6. Reboot the server

   # sync; sync
   # reboot
