Resizing VM (Azure)

  • Updated
  • Products: FlashGrid Server on Azure

Resizing the VM may be needed for performance or cost reasons. Resizing requires database downtime.

  1. Update SGA and PGA sizing parameters for the databases according to the new VM memory size

  2. Skip this step unless you have vm.nr_hugepages parameter in /etc/sysctl.conf manually configured. If you have it manually configured, then update the parameters according to the new VM size.

  3. Stop all running databases.

  4. Stop the FlashGrid server system. The following command will gracefully stop HAS, FlashGrid services and the VM.

    # flashgrid-node poweroff

  5. Resize the VM using the Azure console. The VM automatically starts up at the end of the process.

  6. Wait until ASM is started:

    [grid@myhostname ~]$ srvctl status asm
ASM is running on myhostname

  7. Start the databases stopped previously.
