Enhancement Number
The following example configuration is provided for general information purposes only. Please discuss any questions on the vm technology with the vm vendor.

1. First verify:
  • That the VMware Tools are installed in the CentOS 6 Linux VM (this should be indicated by the ESX GUI) and
  • An Enterprise Database license is in use in order to be able to run quiet points against online databases.
2a Create (or edit) the following 2 scripts:
  • /usr/sbin/pre-freeze-script 
  • /usr/sbin/post-thaw-script 
2b  Provide the following permissions on the scripts:
  • chmod 755 /usr/sbin/pre-freeze-scriptsudo
  • sudo chmod 755 /usr/sbin/post-thaw-script
3. The file /usr/sbin/pre-freeze-script needs the following line to enable a quiet point against the database before the Veeam snapshot is taken:

proquiet <dbname> -C enable

Followed by scripting to parse the database log file that the quiet point has been enabled before proceeding.
The reason for this verification in the database log file is that the 'proquiet <dbname> -C enable' command will return while the quiet point is not yet acknowledged as enabled by the database itself.

The file /usr/sbin/post-thaw-script needs the following line to disable the quiet point against the database after the Veeam snapshot is taken:
proquiet <dbname> -C disable

4. Check theOption “Use VMware Tools Quiescence” in Veeam Backup, and Veeam will ask VMware tools to quiesce the VM, the VMware Tools will then call /usr/sbin/pre-freeze-script and /usr/sbin/post-thaw-script to make sure the snapshot of the database is in a consistent state for re-use and that the online database does not initiate an abnormal database shutdown as a consequence of taking the snapshot requested by the Veeam software.
