SAP HANA Admin Overview
SAP HANA is an
in-memory database for performing real-time data analysis and development of utilization on the most astounding purpose of real-time information. HANA
association figures out how to direct SAP
HANA structure in a single and distributed framework condition. Each HANA
system can contain multi-hub architecture with each center containing diverse
processors for fast speed data analysis and constant data provisioning. You can
use Smart data access to get the data from non-SAP structures without acquiring
the information to HANA database, and virtual tables can be used to perform
read/write information activities.
SAP HANA Administration incorporates the accompanying exercises:
- SAP HANA numerous host framework administration
- SAP HANA System Management and Availability
- SAP HANA Administration Tools
- SAP HANA Backup and Recovery Management
- SAP HANA Lifecycle Management
- SAP HANA Data Provisioning and Integration with non-SAP frameworks
- SAP HANA Security and User Management
Each SAP framework
contains various servers and it can be checked in HANA Studio under
Administration tab. SAP HANA Studio
contains Administration Perspective to deal with all admin tasks in HANA
frameworks.
To check the landscape
of HANA framework, explore to Landscape tab in HANA studio. Administrations
demonstrate every one of the administrations running on HANA framework.
SAP HANA Admin: Multitenant Database
It is conceivable to
set up numerous databases into a solitary HANA framework. When you install SAP
HANA framework in numerous holder modes, you would setup be able to various
isolated databases in single SAP HANA framework. This is called Multitenant
database holders.
You can likewise
clandestine a solitary container HANA framework to multiple container databases
HANA framework. In numerous container HANA frameworks, every database keeps
running on a similar infrastructure and utilizations similar processing assets.
Be that as it may, every database contains following segments:
- Database Users
- Repository
- Catalog
- Backups
- Traces and Logs
- Persistence
All the database
objects - tables, mappings, database views, SQL techniques - are separate for
every database. You can likewise perform cross-database works in the multi-tenant
database.
In SAP HANA framework,
it contains different servers - Name Server, Index Server, Preprocessor, and XS
Server. With numerous container databases, diverse mixes of the above servers
are utilized.
Nameserver keeps up the
landscape subtle elements of the framework and the framework databases run the
Nameserver. The Name server of multitenant databases doesn't contain topology
data and this data is put away in tenant database index.
Preprocessor and
Compile server keeps running on framework databases as they don't contain hold
on information. Each tenant database contains its own particular file server
and SAP HANA Classic Server keeps running on the Index server of tenant
database as a matter of course.

In the above screen capture, you can see 2
databases appropriated crosswise over three has in different container database
frameworks.
In numerous container
architectures, the framework database is set up at the time of installation of
a various container framework or when you change over a single container
framework to different container frameworks. This is utilized to oversee data
about the framework all in all, and furthermore for tenant databases. It is
utilized for Central System Administration in the multitenant environment.
System database
contains data and client data for framework organization and SAP HANA Administration tools, for
example, SAP HANA Studio to associate with the framework database. All the
managerial tasks that are performed in the framework database apply to the
entire framework and you can likewise focus on the design for a particular
tenant database. Framework database contains complete landscape information
around Tenant segments; notwithstanding, it doesn't contain topology-related
data.
SAP HANA Admin: Multiple Host Systems
At the point when your
SAP HANA framework is installed on a single system, it is known as Single Host
System; be that as it may, when you disseminate the system installation on
numerous system, it is called Multiple Host Systems. Utilizing multiple host
systems, you can utilize features, for example, Load Balancing and Scale-Out
component of SAP HANA framework. You can conquer the equipment constraints by
appropriating a heap of your framework on numerous servers.
You can likewise dole
out various tables to various hosts utilizing database segment to part a single
table between hosts and to replicate tables to numerous hosts.
At the point when SAP
HANA framework is installed on multiple hosts, SAP HANA Administrator can perform
begin and stop, reinforcement, or run the update as a single system by taking
single System ID known as SID.
Each SAP HANA framework
contains its own server parts for each host and the demand from the customer
application can be dispersed to various has in different host frameworks.

In the above screen
capture, you can see SAP HANA multiple host system architecture, where HANA
framework has 3 isolate occasions, and each instance has its own server
segments. The ask for from the customer application can be dispersed to any of
the instances in this environment.
