A general introduction to HANA 2.0 with Multitenant Database Container included

What’s different for Business One to launch HANA 2.0 when compare with adopting newer

HANA 1.0 as now?

A little bit complex but more flexible with HANA 2.0 MDC

Objects

What is Multi-tenant?

Perspective from database


Multiple Components One Database (MCOD)

• One SAP HANA DBMS, one database, several schemas, several

applications

• Key tradeoffs:

− DB recovery available for entire DB (not available per

schema)


Multiple Components One System (MCOS)

• More than one SAP HANA DBMS (with one DB in each), 1-n

applications, 1-n schemas

• Key tradeoffs:

− Contention for resources may negatively impact performance

− Additive sizing approach required


Major partner vendors such as VMware and Hitachi offering HANA

deployments on their native virtualization technologies.

• TCO reductions and positive impact on capital expenditures

• Benefits of virtualization management layer for planning and

managing systems landscapes.

• Ease of HW replacements/avoidance of re-certification of OS &

SAP installations

• Starting small and scale along on need basis

• Private and Public Cloud offerings

SAP HANA hardware deployment optionThird-party HANA virtualization and native HANA multitenancy

Virtualization and multitenancy are complementary offerings. Not competitive technologies.

SAP HANA Virtualization

Third-party virtualization/partitioning

technologies are leveraged to host multiple

isolated SAP HANA instances

SAP HANA Multitenancy

Every database tenant represents a dedicated

share of an SAP HANA instance data,

Multitenant Database Containers vs Virtualization

Multitenant Database Containers(Native )• Lower TCO, single software stack

• Central configuration & administration (database level)

• Direct database resource management

• Optimized federation (performance benefits)

• Performance advantages (no virtualization overhead)

• Licensed via SAP HANA

Virtualization• Strong isolation

• Separate SAP HANA revisions option

• Standard federation (SDA)

• Additional virtualization license (e.g. VMWARE)

Positioning SAP HANA multitenant database containers


Multitenant Database Containers provide strong isolation capabilities

• Each database containers has its own database admin and end users, database

catalog, repository, persistence, backups, traces and logs

• Database container Memory and CPU consumption can be configured independently

• Integration with SAP HANA data center operation procedures, housekeeping, backups

(full and/or on database container level), etc.

Multitenant Database Containers share one SID and Revision

• Shared installation of database system software

• Databases container are identified by name or port

• SAP HANA system replication covers whole system (system DB and database

container)

• Additive sizing for all database container

Upgrade from HANA1.0 to HANA 2.0


The feature "SAP HANA multitenant database containers" (or, "MDC") was first introduced starting

with SPS09.

For B1H, will support MDC from HANA 2.0. Do not allow install/ convert to MDC in HANA 1.0

Architecturally, each database container has its own index server, and upon initial deployment,

consumes approximately 8 GB (before any application data is added). This means that the actual

number of databases container that can be deployed is limited by available resources; in other

words, a large number of very small databases container is not possible given the current MDC

architecture.

--Rename

RENAME DATABASE mdc02 TO mdc05;

--Check database container & its status

SELECT * FROM "SYS_DATABASES"."M_SERVICES";

-- Advanced feature

-- Create the fallback snapshot

ALTER DATABASE DEV CREATE FALLBACK SNAPSHOT;

-- Recover to point of snapshot

ALTER SYSTEM STOP DATABASE DEV;

ALTER SYSTEM START DATABASE DEV FROM FALLBACK SNAPSHOT
