How to execute ksh script from bash - bash

Question

I currently have a ksh script which invokes another ksh script. The "parent" ksh script needs to be invoked from a bash shell in the context of the ksh shell user. Trying the following throws back this error message
As user root in the bash shell
su - whics -c '/usr/bin/nohup /whics/t99/wv.4gm/wv99b.4gs/wv99b.sh -s 1 -m u -sleep 5 > ./nohup.out &'
/whics/t99/wv.4gm/wv99b.4gs/wv99b.sh[8]: .: wh_setENV.sh: cannot open [No such file or directory]
wh_setENV.sh is actually in /whics/t99/bin
However, when running the below commands in order I do not get this error
server:~ su - whics
server:/whics/t99 cd ./wv.4gm/wv99b.4gs
server:/whics/t99/wv.4gm/wv99b.4gs nohup ./wv99b.sh -s 1 -m u -sleep 5 &

So in the wv99b.sh file, I changed
. wh_setENV.sh
to
. /whics/t99/bin/wh_setENV.sh
However, now I get the error
cannot read input file wv99b.in
I checked wv99b.in and it is in the same directory as 'wv99b.sh' (i.e. /whics/t99/wv.4gm/wv99b.4gs/ )

Answer 1

UPDATE: After OP modified/updated the question ...
wv99b.in is referenced in wv99b.sh
you don't provide the path for wv99b.in so ...
if you invoke wv99b.sh from some directory other than /whics/t99/wv.4gm/wv99b.4gs ...
when you run your test [ ! -s "${vINFILE}" ] your script (correctly) determines that "${vINFILE}" is not located in the directory where you invoked wv99b.sh from
Net result ... the original problem with sh_setENV.sh has been fixed but now the same exact problem is occurring for wv99b.in, with the same solution needed here ... invoke wv99b.sh from its home directory or provide the full path to wv99b.in.
ORIGINAL POST:
Expanding on Andre's comment ...
In wv99b.sh you have the following line:
. wh_setENV.sh
This is going to look for wh_setENV.sh in the directory where wv99b.sh is invoked from.
In your original example you've provided the full path to wv99b.sh but the question is ... what directory is that call invoked from? We can tell from the error ...
wh_setENV.sh: cannot open [No such file or directory]
... that wv99b.sh was not invoked from /whics/t99/wv.4gm/wv99b.4gs otherwise it would have found wh_setENV.sh.
From your second example it appears that the full path to wh_setENV.sh is: /whics/t99/wv.4gm/wv99b.4gs/wh_setENV.sh so you have a couple options:
in your initial example make sure you cd /whics/t99/wv.4gm/wv99b.4gs before executing wv99b.4gs
or
update wv99b.4gs to include the full path to the location of sh_setENV.sh, eg:
. /whics/t99/wv.4gm/wv99b.4gs/wh_setENV.sh
