PUBLIC SAP HANA Platform SPS 12 Document Version: – SAP HANA Administration Guide Content 1 Getting Started.

To access database objects user needs object privileges on database objects or on the schema in which database object exists. Object privileges can be granted to catalog objects table, view, etc. This privilege is evaluated during query processing. Analytic Privileges grants different user access on different part of data in the Same information view based on user role. Normally, these users don't get deleted from the database. These users are created for an administrative task such as creating an object and granting privileges on database object or on the application. There are two types of Database user as below — User Type Role assigned Standard User This user can create objects in an own schema and reads data in system views. If Privileges required for use of any application, then they are provided through the role. Restricted User cannot create database objects. Restricted User cannot view data in the database. Grant Role to the user.

Calculated Measure: Calculated Measures are created using some calculation on top of an existing measures or attributes. Private Measures: Private Measures are measures used inside a modeling views and cannot be used outside the view. As such, they can only contain the values available in the Columns they relate to.

Variables do not impact the execution HANA Input parameters used to manipulate the execution based on user input. Sometimes you might not want a variable to just restrict the data of a view. But you also want to take input from the user and process it, returning dynamic data based on the user selection. Input Parameters makes this possible. To avoid the risk of losing data in case of hardware failure or power cutoff, persistence layer comes as a savior and stores all the data in the hard drive which is not volatile.

Mention what is modeling studio? Distinct Values: It displays all attributes along with data in graphical format.

Analysis: It displays all attributes and measures in graphical format. Also HANA Column-based storage makes it easy to execute operations in parallel using multiple processor cores. In a column store data is already vertically partitioned. This means that operations on different columns can easily be processed in parallel.

If multiple columns need to be searched or aggregated, each of these operations can be assigned to a different processor core. In addition operations on one column can be parallelized by partitioning the column into multiple sections that can be processed by different processor cores.

What are the different types of Input parameters supported? Currency: Use this during currency conversion where the end user should specify a source or target currency. If the monitored system supports drilling down into alerts, you can click the listed alerts to display further details. If the monitored system supports impact analysis, you can see the relationship between the monitored and other systems in your landscape and how these might be affected if the monitored system has an issue.

The Enterprise Health Monitor displays a list of systems with health indicators for availability, capacity, performance, and alerts. Hover your mouse over a health indicator icon an arrow, for example to see an explanation of what it means.

Click in the System, Availability, Capacity, Performance, or Alerts column for a system to display information provided by the system's cockpit. The links available vary; some systems do not provide links for every column.

You may be prompted to log in to the system. If the list is long, focus on systems of interest by clicking Running Systems or Stopped Systems at the top of the screen, or use the search and filter tools.

Authenticate with a system before you try to start or stop it. Instead, use this user to create dedicated database users for administrative tasks and to assign privileges to these users. Database Header The name of the system or database appears in the shell bar of the launchpad. If the system has the system usage type production, this is also indicated.

This may take a few moments to complete. The new tenant database is automatically added to the Manage Databases app. System Alerts The System Alerts tile indicates the number of high and medium alerts currently raised in tenant databases and provides access to the Alerts app where you can view and analyze alert details.

The system administrator can see only those alerts that identify situations with a potentially system-wide impact, for example, the physical memory on a host is running out. Alerts that expose data in the tenant database for example, table names are not visible to the system administrator in the system database.

It may be helpful to see how alerts are configured in individual tenant databases. The system administrator cannot change the configuration. SAP HANA Database Administration Tiles of this catalog are used to administer an individual database either a single-container system, a tenant database or the system database of a multiple-container system.

Manage Services The tile displays the overall database status. In the app, the status of all services is displayed.
