I would create a file at the OS level called TSCreate.sh and have these commands added to it.
brspace -c force -o process,time -f tsextend -t PSAPTEMP -f sapdata1 -s 1024 -a yes -m 31744 -i 128
brspace -c force -o process,time -f tsextend -t PSAPTEMP -f sapdata2 -s 1024 -a yes -m 31744 -i 128
brspace -c force -o process,time -f tsextend -t PSAPTEMP -f sapdata3 -s 1024 -a yes -m 31744 -i 128
brspace -c force -o process,time -f tsextend -t PSAPTEMP -f sapdata4 -s 1024 -a yes -m 31744 -i 128
Execute the script as orasid.
Good Luck
