A simple way of achieving what you want is to use round brackets to group together all the commands you need to log:

set -x
(

... some commands
.. some more commands
.. including sqlplus etc

) | tee mylogfile 2>&1

all the commands between the round brackets will have their stddout and stderr redirected to your log file. Note that (...) round brackets start a new shell; you could use {...} curly brackets in which case the commands are executed in the current hell

This way you can do everything you need within a single shell script (rather than having an outer script - or your own tired fingers - having to arrange the redirection for an inner script).

NB you can type multiple commands as
( command1; command2; )
all on one line - but I prefer to have
(
command1
command2
)
especially when the commands have lengthy options / argument lists / hereis input
