Error when execute ./hdbinst(sps08)

Hi Expert,

I have downloaded the HANA sps08 software,when I try to run the ./hdbinst,an error was thrown,as below:

"

HANA08:/HANA08/51048744/DATA_UNITS/HDB_SERVER_LINUX_X86_64 # ./hdbsetup

cannot find real path for '/HANA08/51048744/DATA_UNITS/HDB_SERVER_LINUX_X86_64/./../install/sdbrun': No such file or directory

"

But from the installation package,there is no such folder,anyone have idea about this.

Thanks a lot.

Kelvin
