You can setup different shell you want to us as default shell :
/QOpenSys/usr/bin/bsh - Bourne shell (default shell used by SSH sessions)
/QOpenSys/usr/bin/csh -
/QOpenSys/usr/bin/ksh - Korn shell
/QOpenSys/usr/bin/qsh -
/QOpenSys/usr/bin/sh -
This SQL procedure allows to set default shell for *CURRENT user (*DEFAULT for all users) :
CALL QSYS2.SET_PASE_SHELL_INFO('*CURRENT', '/QOpenSys/usr/bin/bsh');
or
CALL QSYS2.SET_PASE_SHELL_INFO('*CURRENT', '/QOpenSys/pkgs/bin/bash');
To show how profiles have default shell set up :
SELECT USER_NAME, SHELL_PATH FROM QSYS2.USER_INFO
WHERE SHELL_PATH <> '';
To show if a system-wide default shell is set :
SELECT PASE_SHELL_PATH FROM QSYS2.USER_INFO WHERE AUTHORIZATION_NAME = 'QSYS';
