SAP HANA Express VM Getting Started

Aus MattWiki

This page contains instructions on how to set up SAP HANA Express Edition Virtual Machine for development and use of 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'))

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


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
