You can also create an own certificate based on the server name of the application (Tier 3). Changed the parameter so that I could connect to HANA using HANA Studio. Here you can reuse your current automatism for updating them. The extended store can reduce the size of your in-memory database. You set up system replication between identical SAP HANA systems. Thanks for the further explanation. A service in this context means if you have multiple services like multiple tenants on one server running.

Although various materials and documents for HANA networks have been available to ease your implementations and re-configurations, you might have found it time-consuming and experienced a hard time to see a whole picture at a glance. Dynamic tiering is targeted at SAP HANA database sizes of 512 GB and larger, where large data volumes begin to necessitate a data lifecycle management solution. This has never occurred in the past as the System Replication monitor immediately reflects the TIER3 as soon as the Replication is configured, Further checks confirmed each volume from TIER2 was indeed replicating to TIER3 and it took the same amount of time it usually takes to synchronize, yet no signs of the TIER3 on HANA Studio Replication monitor If there are multiple dynamic tiering hosts available and you do not specify a host or port, the SAP HANA system randomly selects from the available hosts. the same host is not supported. I'm getting this email alert from the HANA tenant database: Alert Name : Connection between systems in system replication setup, Details : At 2015-08-18 18:35:45.0000000 on hostp01:30103; Site 2: Communication channel closed.

Applications, including utility programs, SAP applications, third-party applications and customized applications, must use an SAP HANA interface to access SAP HANA. Before drawing the architecture, I hope this blog would help to get better understanding of networks required in HANA database regardless of the complexity. Import certificate to HANA Cockpit (for client communication) [, Configure clients (AS ABAP, ODBC, etc.) isolation. Therefore, you are required to have 2 separate networks for system replication, one is for primary site to secondary site and another is for secondary site to tertiary site and each host in your secondary site should have an additional NIC. You have verified that the log_mode parameter in the persistence section of
The datavolumes_es and logvolumes_es paths are defined in the SYSTEMDB globlal.ini file at the system level but are applied at the database level. collected and stored in the snapshot that is shipped. need not be available on the secondary system. with Tenant Databases. System replication cannot be used in SAP HANA systems in which dynamic tiering is enabled. So for s1host1,10.5.2.1=s2host110.4.3.1=s3host1, For s2host110.5.1.1=s1host110.4.3.1=s3host1, For s3host110.4.1.1=s1host110.4.2.1=s2host1. Do you have similar detailed blog for for Scale up with Redhat cluster. * The hostname in below refers to internal hostname in Part1. Are you already prepared with multiple interfaces (incl. From HANA system replication documentation (SAP HANA Administration Guide -> [Availability and Scalability] -> [High Availability for SAP HANA] -> [Configuring SAP HANA System Replication] -> [Setting Up SAP HANA System Replication] -> [Host Name Resolution for System Replication]), as similar as internal network configurations in scale-out Removes system replication configuration. But keep in mind that jdbc_ssl parameter has no effect for Node.js applications! 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 All mandatory configurations are also written in the picture and should be included in global.ini.

Once again from part I which PSE is used for which service: SECUDIR=/usr/sap//HDBxx//sec. There are two possibilities to store the certificates: Due to the flexiblity there are some advantages (copy move of databases) in the newer solution (certificate collection), but if you have to update 100 HANA instances with new certificate every 2 years it can be easier to use the file based solution. connection recovery after disaster recovery with network-based IP
As promised here is the second part (practical one) of the series about the secure network communication.
