Run hdblcm (with root) with the path of extracted software as parameter and install dynamic tiering component without addition of DT host. So we followed the below steps: EC2 instance in an Amazon Virtual Private Cloud (Amazon VPC). You can also encrypt the communication for HSR (HANA System replication). Darryl Griffiths Blog from 2014 SAP HANA SSL Security Essential * as public network and 192.168.1. When complete, test that the virtual host names can be resolved from Configure SAP HANA hostname resolution to let SAP HANA communicate over the I recommend this method, but you can also use the online one (xs set-sertificate) but here you have to follow more steps/options and at the end you have to restart the XSA. Import certificate to HANA Cockpit (for client communication) [, Configure clients (AS ABAP, ODBC, etc.) Storage snapshots cannot be prepared in SAP HANA systems in which dynamic tiering is enabled. If you have to install a new OS version you can setup your new environment and switch the application incl. You can use SAP Landscape Management for Data Lifecycle Manager optimizes the memory footprint of data in SAP HANA tables by relocating data to Dynamic Tiering or HADOOP. network interface, see the AWS Therefore, I would highly recommend to stick with the default value .global in the parameter [system_replication_communication]->listeninterface. There are two types of network used in HANA environment: Since we have a distributed scenario here, configuration of internal network becomes mandatory for better system performance and security. Create virtual host names and map them to the IP addresses associated with client, can use elastic network interfaces combined with security groups to achieve this network United States. tables are actually preloaded there according to the information The truth is that most of the customers have multiple interfaces, with multiple service labels with different network zones and domains. In Figure 10, ENI-2 is has its own security group (not shown) to secure client traffic from inter-node communication. By default, on every installation the system gets a systempki (self-signed) until you import an own certificate. # 2021/03/18 Inserted XSA high security Kudos out to Patrick Heynen If you use a PIN/passphrase keep in mind that you have to use sapgenpse seclogin option to create the cred_v2 file inside the SECUDIR: Sign the certificate signing request with a trusted Certificate Authority (CA) as pkcs7 which will include all CA certificates. Is it possible to switch a tenant to another systemDB without changing all of your client connections? Or see our complete list of local country numbers. Failover nodes mount the storage as part of the failover process. different logical networks by specifying multiple private IP addresses for your instances. You just have to set the dbs/hdb/connect_property parameter to the correct value: In some cases, you may receive an error if you force the use of TLS/SSL: You have to set some tricky parameter due to the default gateway of the Linux server. # 2021/09/09 updated parameter info: is/local_addr thx @ Matthias Sander for the hint It's a hidden feature which should be more visible for customers. * In the first example, the [system_replication_communication]listeninterface parameter has been set to .global and the neighboring hosts are specified. I have not come across much documentation on this topic and not sure if any customer experienced such a behavior so put up a post to describe the scenario Step 2. instances.
