SAP HANA components communicate over the following logical network zones: Client zone to communicate with different clients such as SQL clients, SAP Internal communication channel configurations(Scale-out & System Replication), Part2. instances. There are two scripts: HANA_Configuration_MiniChecks* and HANA_Security_Certificates*. (1) site1 is broken and needs repair; different logical networks by specifying multiple private IP addresses for your instances. In Figure 10, ENI-2 is has its own security group (not shown) to secure client traffic from inter-node communication. Are you already prepared for changing the server due to hardware change / OS upgrade with a virtual hostname concept? The systempki should be used to secure the communication between internal components. (Addition of DT worker host can be performed later). 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. Introduction. Registers a site to a source site and creates the replication
The delta backup mechanism is not available with SAP HANA dynamic tiering. You have performed a data backup or storage snapshot on the primary system. * In the first example, the [system_replication_communication]listeninterface parameter has been set to .global and the neighboring hosts are specified. Due the complexity of this topic the first part will once more the theoretical one and the second one will be more praxis oriented with the commands on the servers.

If you've got a moment, please tell us what we did right so we can do more of it. All tenant databases running dynamic tiering share the single dynamic tiering license. The new rules are global.ini: Set inside the section [communication] ssl from off to systempki. -Jens (follow me on Twitter for more geeky news @JensGleichmann), ######## SQLDBC is the basis for most interfaces; however, it is not used directly by applications. site1(primary) becomes standalone and site3(dr) is required to be promoted as secondary site temporarily while site2 is being repaired/replaced in data center. The values are visible in the global.ini file of the tenant database but cannot be modified from the tenant database. Replication, Register Secondary Tier for System

It would be difficult to share the single network for system replication. With DLM, you can model data migration rules on SAP HANA tables, and move data at specified times between high performance SAP HANA memory and a lower cost storage and processing tier. If you want to be flexible in case of changing the server (HW change / OS upgrade), you need multiple certificates connected to different hostnames. Step 2. reason: (connection refused). Changed the parameter so that I could connect to HANA using HANA Studio. Or see our complete list of local country numbers. 2487639 HANA Basic How-To Series HANA and SSL MASTER KBA With SAP HANA SPS 10, during installation the system sets up a PKI infrastructure used to secure the internal communication interfaces and protect the traffic between the different processes and SAP HANA hosts.

Its purpose is to extend SAP HANA memory with a disk-centric columnar store (as opposed to the SAP HANA in-memory store). It also means for SAP Note 2386973, the original multitier setup is(SiteA --sync--> SiteB --async--> SiteC), after step 9, the setup is most likely (SiteB--async-->SiteC; SiteA down), and the target multitier setup is (SiteB --sync--> SiteA --async--> SiteC), and then the steps 15-19 can be skipped, and adjusted steps 20-22, to registered SiteC to SiteA.
