Is this an SAP Business Suite installation? If so I think you would be better off posting in the SAP Applications on SAP Adaptive Server Enterprise (SAP ASE), Note 2162715 is specific to SAP Business Suite. The upgrade_bs_rdbms.sh script is not part of a general-purpose ASE installation.
For the upgrade steps for a general-purpose ASE, please see the Upgrade chapter in the ASE Installation Guide for Windows. http://ecd1.sybase.com:8100/help/topic/com.sybase.infocenter.dc35888.1600/doc/html/title.html
