Support of Additional Software
Components

Integration of SAP HANA Remote Data Sync – Planning
 SAP HANA remote data sync (RDsync)
synchronizes data between SAP HANA and many
remote databases. Synchronization begins when
a remote database client opens a connection to
the SAP HANA remote data sync server.
 To use SAP HANA remote data sync, we require
at least one SAP HANA host with the role
“Database Worker” and one remote data sync
host with the role “Remote Data Sync”, which can
be configured during SAP HANA system
installation or as part of a scale-out scenario (add
host).
 SAP HANA remote data sync is licensed
separately, as part of the „Real-Time Replication
Option“ sales bundle.

Integration of SAP HANA Remote Data Sync – Implementation
 During database synchronization, the client at the remote site uploads database changes that were made to
the remote database since the previous synchronization. On receiving the data, the RDsync server updates the
SAP HANA data, and then downloads changes from the SAP HANA database to the remote database.
 During installation or addition of an SAP HANA RDsync host, the upload and download path must be specified
with the following parameters:
 To monitor the SAP HANA RDsync server from the SAP HANA cockpit, a database user can be created and
granted one of the following monitoring roles:
sap.hana.sync.monitor.roles::monitor Provides read-only access to the SAP HANA remote data sync tiles
including drill downs.
sap.hana.sync.monitor.roles::administrator Provides full access to the SAP HANA remote data sync tiles including
drill downs and the ability to write changes in the configure tile.
Parameter Default Value Available Interactively
rdsync_downloadpath /hana/download_rdsync/<SID> Yes
rdsync_uploadpath /hana/upload_rdsync/<SID> Yes

Better Support of Multiple Host Roles for Non-Productive Systems
 SAP HANA systems which are making use of SAP
HANA options (for example, SAP HANA dynamic
tiering) in production environments require at least one
SAP HANA database worker host and one SAP HANA
option host.
 Non-productive SAP HANA systems can share the
same resources between the SAP HANA server and
the SAP HANA option by assigning multiple host roles
to the same host.
 As of SPS 10, assigning additional host roles is
possible during installation of SAP HANA options in
any of the three HDBLCM user interfaces.

SAP HANA Database Lifecycle
Manager Web UI

Host Addition and Host Removal Available in the Web UI
 Add one or multiple SAP HANA database
hosts or SAP HANA option hosts at a time
using the HDBLCM Web UI.
 After marking hosts for removal in the
SAP HANA studio, remove one or multiple
hosts using the HDBLCM Web UI.

Advanced Configuration in the Web UI
 Component installation and update in the SAP
HANA database lifecycle manager (HDBLCM)
Web UI now has all of the same parameter
configuration options as in the command-line or
graphical user interfaces.
 The advanced parameters available are non-
interactive parameters and the same parameters
listed when you call the pass-through help in the
command-line interface:
For example:
./hdblcm --action=install --pass_through_help -h
 Pass-through parameters access the
parameters of the underlying hdbinst and
hdbupd programs.

Integration of the Web UI in the SAP HANA Cockpit
 The SAP HANA cockpit home
page can be configured to include
platform lifecycle management tiles
for the actions available in the
HDBLCM Web UI.
 Selecting one of the platform LCM
tiles in the SAP HANA cockpit
redirects to a separate Web browser
tab in which the corresponding
action of the HDBLCM Web UI is
opened.

SAP HANA Database Lifecycle
Manager Command-Line
Interface

Improved Monitoring for Start/Stop Systems
 Detailed information for scheduled processes
 Information is displayed per host

Improved Interactive Command-Line Experience for Installation of
Multiple-Host Systems
 In previous SAP HANA support
package stacks, installing a multiple-
host system in interactive mode required
the non-local hosts to be specified as a
long call option.
 With SPS 10, if you install a multiple-
host system in command-line interactive
mode, you are prompted for individual
details of the non-local hosts.

Multitenant Database Containers – High Isolation
 High tenant isolation can be configured during
installation using the db_isolation parameter,
available interactively in the graphical user interface
or in command-line mode.
 High tenant isolation during system installation
creates tenant separation at OS-user (<sid>adm)
level.
 These OS-users must exist prior to the addition of
an SAP HANA standby host and prior to registering
a host.
 If high isolation is not configured, all database
processes in a multiple-container system run under
the default OS-user <sid>adm.

Improved Logs and Traces
 Instant Logging
– If an LCM action crashes or hangs before the execution is finished, even if no LCM action is enabled,
HDBLCM writes a trace, which has the function of a preliminary (unformatted) log file.
– Instant logging is enabled by default, and the traces are written to the following location:
/var/tmp/<tool>_<timestamp>_<pid>.trc
– Upon program completion, the trace is removed and replaced by the real, formatted log file. The
traces can be saved by setting the following environment variable:
HDB_INSTALLER_TRACE_FILE=<file_path>
 Log Collection
– If you perform platform LCM actions on multiple-host SAP HANA systems, an HDBLCM action ID is
passed to each underlying LCM program on a remote host. Each sub-program writes a copy of the
log file to the following directory:
<installation path>/<SID>/HDB<instance_number>/<host_name>/trace

Phased System Update for Reduced Downtime
SAP HANA Server Component
 With a standard SAP HANA system
update, the system is offline from the time
the update is triggered, including the
preliminary checks, and actual software
switch.
 The phased system update is performed
in two steps:
1. Running the LCM update action with the
“prepare update” flag set. This phase is
performed while the system is online.
2. Running the LCM update action a second
time as usual, which resumes the updates, and
takes the system offline for the software switch.

Automatically Generated Configuration File
 Typically, platform LCM configuration files are created by
generating a template with HDBLCM, filling in parameter
values, and calling the configuration file during execution
of the LCM action.
 As of SPS 10, HDBLCM automatically generates a
configuration file with every LCM action execution, with
the chosen parameter values pre-filled. The automatically
generated configuration files can be used to:
– Easily re-perform the LCM action by passing the auto-
generated configuration file
– Keep a record of the parameters passed for the LCM
action
 The auto-generated configuration files are saved in the
log directory for the LCM action execution.

Further Support for LCM Actions Performed as <sid>adm
 For SPS 09, we introduced functionality to perform
some LCM actions as the system administrator
user, <sid>adm, by means of the SAP Host Agent
framework.
 With SPS 10, it is additionally possible to perform
scale-out system actions, like adding and removing
SAP HANA hosts, as <sid>adm from the graphical
user interface, command-line interface, or Web
user interface.

Customer Feedback Form
 As of SPS 10, you can opt into sharing non-sensitive
system information each time you use the HDBLCM Web UI.
 The system information collected includes:
– Statistical Data
o SAP HANA release
o LCM action selected
– Qualitative Feedback
o Questions about usage
o Comments
o Email – in case you want to be contacted by us
 The system information and feedback collected from
customers helps the SAP HANA LCM team assign
development resources and prioritize tasks.

Other Usability and Supportability Improvements
– Resume Broken Update in All Modes and Interfaces
o System update can be resumed in interactive mode or batch mode
using any of the three HDBLCM user interfaces. The resume is
started from the same host and installation kit, using persistence
files.
– Scale-Out During Installation of SAP HANA Options
o To improve the flexibility of installing an SAP HANA option (for
example, SAP HANA dynamic tiering) to an existing SAP HANA
system, you can perform scale out (host addition) during system
update or the installation or update of additional components.
– SSL SQL Connectivity on HANA Server
o SAP Common Crypto Library (libsapcrypto)
o Open SSL
o Support SSL configuration on SAP HANA server

New Parameters – Description
Description Default
add_local_roles Specifies additional roles of the local host during SAP HANA system installation. Multiple host roles are not supported in
production environments.
worker
add_roles Specifies additional roles for existing SAP HANA hosts during SAP HANA option installation. Multiple host roles are not
supported in production environments.
worker
db_isolation Specifies the isolation of the tenant databases on operating system level for multitenant database container SAP HANA
systems. By default, all database processes in a multiple-container system run under the default OS user <sid>adm. If
it's important to mitigate against cross-database attacks through OS mechanisms, you can configure the system for high
isolation. In this way, the processes of individual tenant databases must run under dedicated OS users belonging to
dedicated OS groups. Database-specific data on the file system is subsequently protected using standard OS file and
directory permissions.
low
Note: The value ‘low‘ in SPS 10,
corresponds to the behavior in
SPS 09.
init_user If the user IDs of existing <sid>adm users are identical on the different hosts but do not match the configured user ID of
the SAP HANA system, then an error message is thrown. The parameter 'init_user' suppresses this error message.
If a <sid>adm does not exist on a host, the <sid>adm is created with the ID of the existing <sid>adm.
---
init_user_home_dir If the <sid>adm user already exists, but does not have a home directory (e.g. network user without local home directory),
this parameter creates or re-creates the home directory on each host according to the configuration of the SAP HANA
system.
---
prepare_update Stops the SAP HANA update before software version switch. The update is resume-able. ---
rdsync_download_path Location of SAP HANA Remote Data Sync file download directory [interactive] /hana/download_rdsync/<SID>
rdsync_upload_path Location of SAP HANA Remote Data Sync file upload directory [interactive] /hana/upload_rdsync/<SID>/

What’s New in SPS 09
Support of Additional Software Components
 Integration of SAP HANA options: SAP HANA dynamic tiering, SAP HANA smart data streaming, SAP HANA accelerator for
SAP ASE
Supportability
 Installation of multitenant database container enabled systems
 SAP HANA Lifecycle Manager (HLM) is no longer supported or shipped
 SAP Landscape Transformation (LT) replication is no longer possible using the SAP HANA platform LCM tools
Usability
 Introduction of a Web user interface for HDBLCM administration and update actions
 Support for performing some LCM actions as the <sid>adm user
 System un-registration performed in HDBLCM graphical user interface

SIGNATURE.SMF – Revisions 90-96
For SAP HANA revision 90-96, if several SAP HANA component SAR archives have been downloaded and
extracted into a single directory, the SIGNATURE.SMF file of the SAP HANA database archive gets overwritten by
the signature of another component. As a result, the wrong SIGNATURE.SMF gets copied to the
<sapmnt>/<SID>/hdblcm directory. If this happens, SAP Host Agent is not able to verify and deploy HDBLCM.
If this situation occurs, open the file <sapmnt>/<SID>/hdblcm/SIGNATURE.SMF and check if there are entries
inside for file paths, starting with SAP_HANA_DATABASE/server/* (for
example SAP_HANA_DATABASE/server/manifest). If there are no such entries or there is no SIGNATURE.SMF
file at all, see SAP Note 2078425, section Repairing Installations with Missing Signature. The problem is most
likely caused by improper extraction of the SAP HANA component archives before installation or upgrade. See
section How to Prepare SAP HANA Packages for Installation or Update for the correct preparation procedure.
