SAP HANA System Replication Scale Up: Performance-Optimized
Before proceeding with the installation, please make sure of the following:
-
There are two machines with SAP HANA installed.
Note that the machine you run the wizard on becomes the primary node in the cluster.
- Verify that both databases are up and running.
-
You have created one of the following:
-
A key in the HANA Secure User Store (using the
hdbuserstore
utility) on the primary HANA node.
If you are configuring a multi-tenant HANA installation (default for HANA versions 2.0 SPS01 and above), please make sure that the secure store key is properly configured for connecting to the SystemDB
, i.e., specify port 3<SID>13
in the environment settings and SystemDB
as the target database.
-
An initial HANA backup (of the
SystemDB
and all tenant databases, in an MDC setup) on the primary HANA node.
Please note that if you prefer to perform backup manually on HANA 2.0, you should also make sure that the SSFS keys are the same on both HANA nodes.
