HISTFILE needs to be exported:
HISTFILE=$HOME/.sh_history; export HISTFILE

Check the user's $HOME/.profile as well as the /etc/profile.

Hi,

Every variable defined in .profile or profile has to be exported otherwise that will not be available for use in shell.

IF you are going to CDE based login then,

.profile and /etc/profile will not be executed.

Environment variables related CDE login will be exported in .dtprofile so that particular environment variable will be used on shell usage.

If you did not export environment variables, then it will be local to that script. It can not be accessed for all operations on current shell.

If you are going to use non-CDE login then make settings of HISTFILE environment variables on /etc/profile ( come profile ) or .profile ( user's profile).

HTH.

Hello,
uncomment line DTSOURCEPROFILE=true in .dtprofile and will read also the .profile
