I had a question regarding the DB protocols supported by tshark. I
saw mysql support but is there also support for other protocols for
queries to Oracle or DB2?
I have the impression that Oracle uses a protocol that Wireshark calls
"TNS" (Transparent Network Substrate); that protocol is dissected by
Wireshark/TShark.
Wireshark/TShark also dissect a protocol called DRDA (Distributed
Relational Database Architecture); a comment in the DRDA dissector says:
* DRDA in a nutshell
*
* DRDA stands for Distributed Relational Database Architecture.
* It is a protocol between database client and database server
published by
* the Open Group (www.opengroup.org) DDM (Distributed Data
Management) is an
* data management interface which allows to exchange structured data
between
* systems. DRDA is specific to relational databases and uses a
subset of DDM
* to transport its data. The IBM DB2 product uses the DRDA protocol
from
* version V8. Unless negotiated differently during the handshake,
the fields
* of the DDM commands and reply messages are in EBCDIC.

* DRDA Version 3 Vol. 3: Distributed Relational Database
Architecture,
