Basic Concept and Development News for SAP HANA SPS03

Summary


LT Replication Server for SAP HANA leverages proven SLO Technologies

Application Lifecyle MgmtSLO technologies are used since more than 10 years and used in several hundred projects per year

Key offerings foster SAP‘s Application Lifecycle Mgmt concept

LT replication Server as a new use case leverages several SLO technologies


Current Status - SAP LT Replication Server for SAP HANA

SAP LT Replication Server was quickly adopted and

is today the default solution for real-time

integration of SAP sources into SAP HANA

Some HANA customers are already live using SLTfor data replication from SAP sources A lot of Proof-of-Concept projects are in process-> many more live customers expected by end of 2011Real-time data replication is a key capability requested by HANA customers


Key Benefits of LT Replication Server for SAP HANA

Key benefits of trigger based approachAllows real-time (and scheduled) data replication, replicating only relevant data into HANA from SAP sources and non-SAP sources

Ability to transform data into HANA format while replicating data in real-time

„Unlimited“coverage of SAP releases (SAP R/3 4.6C onwards) for SAP ERP and ABAP-based SAP applications)

Leverages proven SLO technologies (Near Zero Downtime, TDMS, SAP LT)

Simple and fast installation and configuration and fully integrated with HANA modeler UI (as of SPS02)

LT replication server is the ideal solution for all HANA customers who need real-time (and scheduled) data

replication sourcing from SAP and NON-SAP sources


Commercial and Software Shipment Aspects

Commercial AspectsLT Replication Server for SAP HANA is part of SAP HANA software license model (HANA Enterprise Edition)

Software Shipment LT Replication Server for SAP HANA is part of SAP HANA software shipment and fully integrated into the SAP HANA modeler UI

LT replication server does not have to be a separate SAP system and can run on any SAP system with SAP

LT Replication Concept: Trigger-Based Approach (2/2)Set-up of Data Replication in SAP HANA System

Choose Data Provisioning to launch HANA Modeler UI

1. 1. Select source system as defined in LT replication server, related system information and schema will be displayed

2. 2. Use button Load and / or Replicate to set-up the data replication

3. 3. Use button Stop Replication to end or to restart replication

HANA Modeler – Data Provisioning UI - Suspend/Resume

With SPS03, in the HANA modeler, it will be possible to suspend a table from the replication process and to resume it a later point in time.

Suspend - Pause a table from a running replication Trigger will not be deleted at the source systemDelta will still be stored in logging tables within the source system

Resume - Restart replication for a suspended tablePrevious suspended replication will be resumed (no new initial load required)


Multi Source System Support

This allows you to use multi schemas (with the same schema name) to replicate data from multiple source systems into a single schema in the HANA system (N:1 replication).

This allows you to use multiple schemas (with the same schema name) to replicate data from multiple source systems into the same schema into different HANA systems (1:1 with the same schema name).

Schema 123 – source B

With SPS03 the definition and use of schemas is more flexible -schema name does not have to be unique anymore.


Advanced Role and Security Concept

1. Gain flexibility to grant authorization to HANA Studio users

Replication user (name is equal schema name) is generated for replication purposes

Three additional schema specific roles are generated and can be assigned to a user

Select the user and assign the relevant roles (via the green plus symbol) in the HANA Studio

Name Role Purpose

Data Provisioning <SCHEMA>_DATA_PROV Data provisioning - deploy replication orders

Power User <SCHEMA>_POWER_USER Power user - allow modification within the replication schema

User Admin <SCHEMA>_USER_ADMIN Can call the RS_GRANT_* and RS_REVOKE_* procedures

2. More flexibility for HANA DB user to establish DB connection3. Streamlined authorization (user role: SAP_IUUC_REPL_REMOTE) for SAP source systems

…Data Portions

The data for transformation will be splitted into portions (default: 40.000 lines)

The portions will be processed successively, mapped on LT Replication Server and transferred to HANA

Transformation rules (e.g. filtering, data conversion) is possible at several points of the process via ABAP includes

Implementation of transformation rules is possible by maintaining table IUUC_ASS_RUL_MAP on the LT Replication Server (as additional expert function also rules can be defined for triggers in source system)

Applying transformation rules may lead to data inconsistency and delay data replication process


Jobs & Connections and Statistics

Within the tab Jobs and Connections you get details about the status of the master job, the load jobs and the connection details of all the involved systems.

You can restart the master job, if it stopped for any reason.

On the Statistics tab page, you get the information about the tables which are in replication mode, the current action and status. In addition you get the replication latency of each table, calculated with the median, the minimum and the maximum.


Configuration for non-SAP source system within the LT replication server

To replicate from Non-SAP source system select Legacy and the affected Database System.

Depending on the Database System, additional required information needs to be specified (e.g. for DB2 specify

the DB Connection and the Tablespace name).

Start with transaction LTR

LT replication server transfers in a first step all metadata table definitions from the non-SAP sourcesystem to the HANA system into the tables DD02L and DD02T. From the HANA perspective everythinglooks like you work with a SAP source. When a table replication is started, LT replication server createslogging tables within the source system. Only the read modules are created in the LT replication server(for SAP sources the read modules are located in the source system only). The connection from LTreplication server to the non-SAP source system is established by means of a database connection.

With SPS03, LT replication server also supports real-time replication for non-SAP sources.

For non-SAP source systems, the customer database license needs to cover a permanent database connection with 3rd party products like LT replication server. (*) Since a DB connection from LT replication server to a non-SAP system is required, the OS/DB restrictions of NetWeaver 7.02 apply (see at http://service.sap.com/pam)

Summary


Summary and Key Take Aways

LT replication concept is based on the proven SLO technology (used for NearZeroDowntime, TDMS, etc.) used by hundreds of customerswith large DBs.

It provides a holistic concept and valuable features to manage the data replication into SAP HANA very efficient and reliable

SLT includes with DMIS_2010 SP05 key improvements and enhance-ments to provide a more complete E2E replication solution for SAP HANA SPS03 - also simplifying a lot of technical operations aspects

LT replication server is the ideal solution for all HANA customers who need real-time (and scheduled) data

replication sourcing from SAP and NON-SAP sources


Frequently Asked Questions

Is SAP LT Replication Server included in the HANA license?Yes - it is part of the HANA - Enterprise Edition license

What is the recommended set-up / landscape strategy using SAP LT Replication Server with SAP HANA?

Installing and operating SAP LT Replication Server is technically possible on any SAP NetWeaver 7.02 instance (for example source system) as long as the technical prerequisites (SP level; SAP Kernel, etc.) are fulfilled and related implications (e.g. performance) are consideredFirst customer experiences show that non-productive SLT instances are sometimes running on SAP Solution Manager (or SAP source systems) but the productive instance of SAP LT replication server is kept separately

Is it also possible to do real-time data replication with non-SAP sources?Yes - using SLT (DMIS_2010 with SP05) with HANA SPS03 also includes capabilities for data replication from non-SAP sources (only for SAP supported databases!)

Has the data replication a negative impact on the performance of the source system?

No - experience from POCs and first live customers prove that there is no measurabl eimpact of the trigger-based approach on the source system. Main load is covered by the SLT system

If SLT is already in use, what to consider when applying SP05 to leverage new features available HANA SPS03
