What's New?


Platform Lifecycle Management (PLM) for SAP HANA 2.0 is a mature and stable technology which has not changed much over the last four support package stacks.

For SPS 03, support for persistent memory has been added and software authenticity verification is now standard included. To support this, new installation parameters have been added. Further, there have been some usability enhancements.

Software Authenticity Verification


Secure-by-design and secure-by-default are important SAP software development standards. As of SPS 03, software authenticity verification is executed by default by the SAP HANA database lifecycle management tool (hdblcm) for any (downloaded) component.

Support for Persistent Memory


As of SPS 03, SAP HANA 2.0 supports persistent memory, also referenced as non-volatile RAM. This storage type requires a specific file system that supports DAX (Direct Access).

At the time of writing, the technology is not available yet but the key performance benefit will be system downtime minimization. Persistent memory allows you to keep the main storage of the column tables loaded into memory even when power is off. In case of a hard stop (power off, system crash, or user error), startup time will be considerably reduced.

You can enable persistent storage for the database as a whole or for specific column tables, column partitions, or even individuals columns - so there is a high degree of flexibility.

New HDBLCM Parameters


To validate the signature:
–action=[install|update] –verify_signature

When using persistent memory:
–action=install –use_pmem
–action=install –pmempath=/hana/pmem/<SID>

To specify a temporary location for file extraction and the location of the executables:
–action=extract_components –extract_temp_dir=<extract_temp_dir>
–action=extract_components –overwrite_extract_dir
–action=extract_components –sapcar_location=<sapcar_location>
–action=extract_components –tar_executable_location=<tar_executable_location>
–action=extract_components –unrar_executable_location=<unrar_executable_location>

To enable interactive input of system database user (SYSTEM) password, or (in case of a single-tenant to multi-tenant system conversion) to use the single-container database user password for the system database user to be created:
–action=update –systemdb_system_user_password
–action=update –systemdb_use_singledb_user_password

To specify the path to the (trust) certificate and key for use by XS advanced:
–xs_cert_key=<path>
–xs_cert_pem=<path>
–xs_trust_pem=<path>

What's Changed?


Resume Update after Delivery Unit Import Error


The SAP HANA database lifecycle management tool (hdblcm, -gui, -web) is a wrapper tool that calls utility tools to perform the action. Previously, when an upgrade failed because of a delivery unit import error, you had to manually complete the task using any of these utility tools. Now, you can just rerun hbdlcm to resume the update.

Usability Improvement


You can now verify existing configuration parameters when using the SAP HANA database lifecycle management tool web interface.
