Tip: TCP/IP is the recommended communication protocol for communication with Db2 for z/OS®. Although SNA communication remains supported in Db2 13, SNA communication and the VTAM interface are deprecated, and support will be removed in the future. 
If your Db2 environment still uses VTAM communication, see Converting to TCP/IP communication from VTAM in Db2 for z/OS.
