Losing Command History from Prior Sessions
We are running AIX. Shell is ksh. I used to have the ability to recall commands from prior sessions using <exc> k. Now, suddenly, I only can recall commands run during the current session. When I start a session, I have no command history. Also, when I run the shell command from a current session, I lose my command history.

New to Unix. Not getting much help from support folks who claim that we never had this ability to recall commands from prior sessions. Something has changed, or I'm losing it.

Any help or ideas greatly appreciated.
