Configuration of HanaXsBlobStoreTest

Blob store is used for storing binary large objects or blobs which are typically composed of unstructured data such as text, images, and videos, along with their metadata.This test discovers the blob store residing in the SAP HANA database and reports the size of blob set, unique blobs and shared blobs. This test also reveals the failures occured while storing blobs in the blob store such as simple and bulk update failures, cleanup failures and statement failures. This test also tracks the number of operation failures such as bulk add and clean up operations along with average clean up time. This way, the test not only leads administrators to the problem areas of a storage account, it also reveals the probable cause of these problems, thereby enabling administrators to act quickly and eliminate the issues.

The default parameters associated with this test are:

• The TEST PERIOD list box helps the user to decide how often this test needs to be executed.

• In the HOST text box, specify the HOST for which this test is to be configured.

• Specify the port at which the specified host listens to in the PORT text box.

• Specify the name of the Organization that contains the spaces in which the appplications are deployed on HANA XS in the ORGANIZATION textbox. Example: org

• Specify a comma-separated list of Spaces for the specified Organization in HANA XS in the SPACES textbox. The Spaces specified in this text box need to be included for monitoring. Example: SAP,PROD

• Specify the full path to the location where the HANA XS is installed in the XS PATH textbox. Example: /HANA/shared/HDB/xs/bin/

• Typically,to connect to a HANA XS and run tests,the eG agent requires the permissions of a HANA XS client user who has been assigned the role collections as XS_CONTROLLER_ADMIN_READ_ONLY, also assigned the OrgAuditor, SpaceAuditor roles for specified organization and spaces.Ideally, you will have to create a new user role on the HANA XS for this purpose, associate the above-mentioned collections with that role,and assign the new role to an existing HANA XS client user.Once the new role is assigned to a HANA XS client user,specify the name of this user against CLI USER text box. Example: Create user as XSA_ADMIN2. Execute below query in SAP HANA studio.

  CREATE USER XSA_ADMIN2 PASSWORD “admin”;

  Assign roles for HANA XS CLI user using HANA XS Client commands mentioned below:

  • xs assign-role-collection XS_CONTROLLER_ADMIN_READ_ONLY XSA_ADMIN2;

  • xs set-org-role XSA_ADMIN2 orgname OrgAuditor;

  • xs set-space-role XSA_ADMIN2 SAP SpaceAuditor;

• Specify the password of the specified CLI User in the CLI PASSWORD text box.

• Confirm the password by retyping it in the CONFIRM PASSWORD text box.

• The XS CLI client tools are installed by default on the SAP HANA server. However, you can also download and install the client tools locally, if you want to connect to SAP HANA from your local machine. Hence, set the CLI LOCATION flag to Remote or Local based on the location of HANA XS Client.

• Specify the URL of the API end point to connect to the XS advanced controller on the SAP HANA server in the CLI ENDPOINT text box. Syntax for this CLI endpoint is : https://<Hostname>: 3<Instance Number>30. Example: https://vhcalhdbdb.dummy.nodomain:30030

• If multiple components of the same component type are awaiting configuration, then an APPLY TO OTHER COMPONENTS button will appear in this page. Clicking on this button will allow you to apply the configuration to all/selected components of that type.

• Once the necessary values have been provided, clicking on the UPDATE button will register the changes made.

When changing the configuration for specific servers, a “*” beside the text box corresponding to the parameter signifies that these values have to be manually configured by the user. The parameter values that require to be configured will typically be prefixed with a “$” or contain a series of “*”. A value of “none” in the parameter value indicates that the corresponding parameter value can be changed if required.
