SAP HANA Express Getting Started

Aus MattWiki

This page contains instructions on how to set up SAP HANA Express Edition Virtual Machine for development and get started with the SAP training material.

Applies to SAP HANA Express Edition 2.0 SPS03 and SPS03

Most important step in order to prevent build errors afterwards is to Activate Tenant Database

Setup Environment

Activate Tenant Database

  • Login to SAP HANA XS Advanced Cockpit, probably at https://hxehost:51036/cockpit#/xsa/overview
  • Go to Tenant Databases
  • For Tenant Database HXE Click on Button Activate -> Enter Master Password
  • Map Database to Organization HANAExpress and Space development. Activate default checkbox
  • Click Save

Database Explorer

Find database SQL port numbers starting from the system database: 

SELECT 
  DATABASE_NAME, 
  SERVICE_NAME, 
  PORT, 
  SQL_PORT, 
  (PORT + 2) HTTP_PORT 
FROM SYS_DATABASES.M_SERVICES 
WHERE DATABASE_NAME='<DBNAME>' 
  and ((SERVICE_NAME='indexserver' and COORDINATOR_TYPE= 'MASTER') 
  or (SERVICE_NAME='xsengine'))

    • User: System
    • Passwort: Master Password
  • Click on OK

Web IDE

Clone Project

  • Clone from desired repository

SFLIGHT

SQL Commands in Tenant (Needed for Exercise 2.6): 

CREATE USER CUPS_SFLIGHT PASSWORD "HanaRocks01" SET PARAMETER CLIENT = '001';
ALTER USER CUPS_SFLIGHT DISABLE PASSWORD LIFETIME;
GRANT SELECT ON SCHEMA SFLIGHT TO CUPS_SFLIGHT WITH GRANT OPTION;
GRANT SELECT METADATA ON SCHEMA SFLIGHT to CUPS_SFLIGHT WITH GRANT OPTION;

CREATE ROLE SFLIGHT_CONTAINER_ACCESS;
GRANT SELECT, SELECT METADATA ON SCHEMA SFLIGHT TO SFLIGHT_CONTAINER_ACCESS WITH GRANT OPTION;
GRANT SFLIGHT_CONTAINER_ACCESS TO CUPS_SFLIGHT WITH ADMIN OPTION;

Central DB

Install CentralDB MTAR (Needed for Exercise 2.8): In this exercise, we will configure access and synonyms between our local project container and an already existing container deployed on this system. In order to perform this exercise in your own system, you will have to first download and deploy (with the –use-namespaces option) this MTA into your development space from: https://github.com/SAP/hana-xsa-opensap-hana7/raw/snippets_2.3.2/ex2/openSAP.CentralDB_1.1.2019.mtar

xs deploy help: https://help.sap.com/viewer/4505d0bdaf4948449b7f7379d24d0f0d/2.0.03/en-US/308f2041995c41a88bbb197cf2a984f7.html#loio308f2041995c41a88bbb197cf2a984f7__section_irt_3dc_zs 

xs deploy openSAP.CentralDB_1.0.2019.mtar --use-namespaces

Install Exercises Application

The following statements are based on my implementation of the HANA7 exercises. Repository:

https://github.com/mattxdev/openSAPHANA

This repository is based on the original HANA7 repository from SAP located at:

https://github.com/SAP-samples/hana-xsa-opensap-hana7

Create User Provided Services

XSA Commands: 

xs cups CROSS_SCHEMA_SFLIGHT_00 -p "{\"host\":\"localhost\",\"port\":\"39015\",\"user\":\"CUPS_SFLIGHT\",\"password\":\"HanaRocks01\",\"driver\":\"com.sap.db.jdbc.Driver\",\"tags\":[\"hana\"] , \"schema\" : \"SFLIGHT\" }"
xs cups sap.hana.democontent.epm.services.images.00 -p "{\"host\":\"www.loc.gov\",\"port\":\"80\",\"tags\":[\"xshttpdest\"] }"

Create Additional Services

xs create-service xsuaa space openSAPHANA_00-uaa -c xs-security.json
xs create-service auditlog free openSAP-ex-log
xs create-service sapui5_sb sapui5-1.52 openSAP-ui5

Create XS Advanced Roles

xs create-role openSAPHANA-ex Viewer Viewer_300 -a "{\"client\":{\"value\":\"300\",\"source\":\"static\"},\"country\":{\"value\":\"US\",\"source\":\"static\"}}"

xs create-role openSAPHANA-ex Editor Editor_300 -a "{\"client\":{\"value\":\"300\",\"source\":\"static\"}}"

Build DB sequence

Build zunächst user-db dann die core-db / db.

Run Sequence

Run XSJS as Node.js Application Run SRV as Node.js Application Run WEB as Web Application

Trouble Shooting

Build of DB fails with invalid user name

Error Message

Using grantor service "ServiceName_1" of type "sql" Error: Error executing: GRANT "SFLIGHT_CONTAINER_ACCESS" TO "OPENSAPHANA_OPENSAPHANA_HDI_CONTAINER_1#OO"; (nested message: invalid user name: OPENSAPHANA_OPENSAPHANA_HDI_CONTAINER_1#OO: line 1 col 37 (at pos 36)) grantor service: "ServiceName_1", type: "sql", user: "CUPS_SFLIGHT" file name: cfg/SFLIGHT.hdbgrants

Root Cause

User name OPENSAPHANA_OPENSAPHANA_HDI_CONTAINER_1#OO was created in a different tenant database, i.e. SYSTEM instead of HXE.

The HXE tenant database has to be activated and mapped as default in the VM first. If this is not the case any created projects will create users in SYSTEM database instead of the development tenant database.

Fix

No fix known besides to dropping the VM entirely and setup again and following the steps above Setup Environment

Root Cause

Missing User DB.

Fix
