Hi Ruby
You can follow these steps.
Log on to the server on which the of the SAP HANA master index server is running as the operating system user (that is, <sid>adm user).2.
Open a command line interface.3.
Shut down the instance by executing the following command:/usr/sap/<SID>/HDB<instance>/exe/sapcontrol -nr <instance> -function StopSystem HDB4.
Start the name server by executing the following commands:○/usr/sap/<SID>/HDB<instance>/hdbenv.sh○/usr/sap/<SID>/HDB<instance>/exe/hdbnameserver5.
Start an index server in console mode by executing the following commands:○/usr/sap/<SID>/HDB<instance>/hdbenv.sh○/usr/sap/<SID>/HDB<instance>/exe/hdbindexserver -console
You see the output of a starting index server. When the service has started, you have a console to the SAP HANA instance where you are logged on as the SYSTEM user.6.
You can reset the SYSTEM user's password and store the new password in a secure location with the following SQL command:ALTER USER SYSTEM password <new password>
Thanks,
