The creation of the database must be made by the SAP HANA UNIX user, on the machine where SAP HANA is installed. The SAP HANA UNIX HANA UNIX user is assumed to be used for the installation steps below.

1. Create the SAP HANA database instance. The working directory is saphana.

   Code Block
   $ ./saphana_create_instance.sh [<SAP HANA admin user>] [<SAP HANA admin password>]

   If no error occurs, the database creation will now be completed and the rest of this section can be ignored.

   Tip
   title Hint!
   When the instance creation script has been executed, there is a log file in the /tmp directory that can be used for trouble shooting. The mz_db.log file contains SAP HANA responses from the database creation.

   
   

2. If the script fails, clean up the system before the next try:

   1. Stop DB (Needed to drop it):

      Code Block
      hdbsql -i 90 -d SystemDB -u SYSTEM -p QAmzadm1n "ALTER SYSTEM STOP DATABASE MZ"

   2. Drop DB:

      Code Block
      hdbsql -i 90 -d SystemDB -u SYSTEM -p QAmzadm1n "DROP DATABASE MZ"

If you require to change any installation parameter defined in the install.xml, the installation must be restarted from the generation step. For further information, see SAP HANA Preparations.
