The shell (/bin/sh to be specific) writes all commands into its history file .sh_history. This is kept across sessions. Command line editing when in a ssh (telnet/rlogin) shell session will use this file, as well as the "fc" and "history" shell commands.
When using TSO/OMVS (the 3270 interface), the OMVS TSO command processor is the interface between the shell and your 3270 terminal. It is OMVS that keeps a history of everything entered *in memory* only. Once you logout, OMVS command processor will terminate and release its storage. There goes the OMVS command history. Note that .sh_history is still feeded when logged in through OMVS, but OMVS has no access to this file.
