Database system checksumming to prevent network corruption not caught by TCP checksumming Since TCP checksumming is not sufficient to detect/prevent all corruption, do modern database systems (e.g. SQL Server, MariaDB / MySQL, Oracle, etc.) use any additional checksumming of network traffic as part of their client/server protocol?  

I did some searching but wasn't finding anything which made me wonder if perhaps they don't and just roll the dice. 

Got a good answer on Oracle. Would like to hear about SQL Server and MariaDB  / MySQL as well.
Oracle has a variety of encryption and integrity features that are a part of its network protocols.

See Configuring Encryption and Integrity Parameters Using Oracle Net Manager in section 13 Configuring Oracle Database Network Encryption and Data Integrity of the Oracle Database Security Guide.
