Uninstall the SAP HANA System Using the Graphical User Interface

You can uninstall an SAP HANA system using the SAP HANA database lifecycle manager (HDBLCM) graphical user interface.

Prerequisites

• You are logged in as root user.
• Operating system users are set up for use with SAP HANA XS advanced. For information, see SAP Note 2243156 - Secure user setup for SAP HANA extended application services, advanced model.
• The operating system administrator (<SID>adm) user may exist prior to installation. Make sure that you have the password of the existing <SID>adm user, and that the user attributes and group assignments are correct. The SAP HANA database lifecycle manager (HDBLCM) resident program will not modify the properties of any existing user or group.

NoteUsing the SAP HANA database lifecycle manager, it is possible to remove the SAP HANA server, SAP HANA client, SAP HANA studio, HLM, Application Function Libraries (AFL and the product-specific AFLs POS, SAL, SCA, SOP, UDF), SAP liveCache applications (LCAPPS), or SAP HANA smart data access (SDA), but it is not possible to remove the SAP host agent or the Solution Manager Diagnostics (SMD) agent. If you need to uninstall the SMD agent, see SAP Note 1858920 in Related Information.
