This tutorial gives you an overview and talks about the fundamentals of SAP HANA Administration. An SAP HANA system consists of several servers, the most important of which is the index server.
A multiple-host or distributed SAP HANA system is a system that is installed on more than one host. An SAP HANA instance is the set of server components of a distributed system that are installed on one host. A multiple-container system always has exactly one system database and any number of multitenant database containers (including zero), also called tenant databases. Hana supports recovery measures ranging from faults and software errors, to disasters that decommission an entire data center.
High availability is achieved by eliminating single points of failure (fault tolerance), and providing the ability to rapidly resume operations after a system outage with minimal business loss (fault resilience).
The key to achieving high availability is redundancy, including hardware redundancy, network redundancy and data center redundancy. Hardware Redundancy – SAP HANA appliance vendors offer multiple layers of redundant hardware, software and network components, such as redundant power supplies and fans, enterprise grade error-correcting memories, fully redundant network switches and routers, and uninterrupted power supply (UPS). Software – SAP HANA is based on SUSE Linux Enterprise 11 for SAP and includes security pre-configurations (for example, minimal network services).
Persistence – SAP HANA persists transaction logs, save-points and snapshots to support system restart and recovery from host failures, with minimal delay and without loss of data. Standby and Failover – Separate, dedicated standby hosts are used for failover, in case of failure of the primary, active hosts. We have come across many developers in USA, Australia and other countries who have recently got the job but they are struggling to survive in the job because of less technical knowledge, exposure and the kind of work given to them.

The challenge is to decide about having one repository for each Master Data Domain or combining several master data domains into one repository. SAP ECC function working on change management, configuration management and document management.
Master data service consisting of core services, memory cache, database abstraction, repository management. Learn SAP MDM in developing strong management skills in the project areas of SAP MDM and GDS Global data synchronizing. Learn SAP MDM to ability to lead and guide a team of SAP functional WM,MM consultants in supply chain.
Learn SAP MDM to take responsibility in taking system design and development by the SME to the end users by developing and reviewing test plans and test script. The following figure shows a distributed system with three hosts, which each run a name server, index server, and so on. It is perceived as one unit from the perspective of the administrator, who can install, update, start up, shut down, or backup the system as a whole.
The name server contains landscape information about the system as a whole, including which tenant databases exist. High availability is the name given to a set of techniques, engineering practices and design principles that support the goal of business continuity.
Fault recovery is the process of recovering and resuming operations after an outage due to a fault.

Disk storage systems use batteries to guarantee writing even in the presence of power failure, and use striping and mirroring to provide redundancy for automatic recovery from disk failures. Additionally, the SAP HANA system software also includes a watchdog function, which automatically restarts configured services (index server, name server, and so on), in case of detected stoppage (killed or crashed). Mindmajix has highly technical people who can assist you in solving technical problems in your project. The job support is provided by Mindmajix Technical experts who have more than 10 years of work experience on IT technologies landscape.
We deliver the right mode of SAP MDM training online for every individual round the planet with flexible timings. The different server components of the system share the same metadata and requests from client applications can be transparently dispatched to different servers in the system. Disaster recovery is the process of recovering operations after an outage due to a prolonged data center or site failure.
Generally speaking, all these redundancy solutions are transparent to SAP HANA’s operation, but they form part of the defense against system outage due to single component failures. Unlike the name server in a single-container system, the name server of the system database in a multiple-container system does not own topology information, that is, information about the location of tables and table partitions in databases. Preparing for disasters may require backing up data across longer distances, and may thus be more complex and costly.
