Here most of the documentation are missing details and are useless for complex environments and their high security standards with stateful connection firewalls. 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. Therefore, I would highly recommend to stick with the default value .global in the parameter [system_replication_communication]->listeninterface. # 2020/04/14 Insert of links / blogs as starting point, links for part II Source: SAP 1.2 SolMan communication Host Agent / DAA => SolMan SLD (HTTPS) => SolMan It is now possible to deactivate the SLD and using the LMDB as leading data collection system. But still some more options e.g. (3) site3 is still registered to the site2 (as it's not impacted, async only as remote DR); Here it is pretty simple one option is to define manually some command line options: cp /usr/sap/SID/HDB00/hostname/sec/sapsrv.pse /usr/sap/SID/HDB00/hostname/sec/sapcli.pse. The extended store can reduce the size of your in-memory database. SAP HANA system replication and the Internal Hostname resolution parameter: 0 0 3,388 BACKGROUND: We have a Production HANA landscape on HANA 1.0 SPS12 with a 4+0 Scaleout setup with HANA System replication to TIER2 in the same Primary Datacenter and TIER3 in the Secondary Datacenter Introduction. To learn replication network for SAP HSR. Following parameters is set after configuring internal network between hosts. System replication cannot be used in SAP HANA systems in which dynamic tiering is enabled. is deployed. Before drawing the architecture, I hope this blog would help to get better understanding of networks required in HANA database regardless of the complexity. global.ini -> [system_replication_hostname_resolution] : For more information about how to attach a network interface to an EC2 You have verified that the log_mode parameter in the persistence section of
You use this service to create the extended store and extended tables. the global.ini file is set to normal for both systems. Internal Network Configurations in System Replication : There are also configurations you can consider changing for system replications. We have a Production HANA landscape on HANA 1.0 SPS12 with a 4+0 Scaleout setup with HANA System replication to TIER2 in the same Primary Datacenter and TIER3 in the Secondary Datacenter In particolare, la configurazione usa la replica di sistema HANA (HSR) e Pacemaker in macchine virtuali Linux (VM) di Azure Red Hat Enterprise. With an elastic network interface (referred to as Early Watch Alert shows a red alert at section " SAP HANA Network Settings for System Replication Communication (listeninterface) ": SAP Knowledge Base Article - Preview 2777802-EWA Alert: TLS encrypted communication expected (when listeninterface = .global) Symptom SAP is using mostly one certificate for all components (host agent, DAA, SystemDB, Tenant) which belongs to the physical hostname (systempki). Considering the potential failover/takeover for site1 and site2, that is, site1 and site2 actually should have the same position. SAP Real Time Extension: Solution Overview. SAP HANA System, Secondary Tier in Multitier System Replication, or
The additional process hdbesserver can be seen which confirms that Dynamic-Tiering worker has been successfully installed. To learn more about this step, see This will speed up your login instead of using the openssl variant which you discribed. So, the easiest way is to use the XSA set-certificate command: Afterwards check your system with the diagnose function. SAP HANA Network and Communication Security ########. SAP Note 1834153 . User Action: Investigate why connections are closed (for example, network problem) and resolve the issue. IMPORTANT : the parameters in the global.ini must be set prior to registering the secondary system which means that you need to un-register and re-register if you want to change the configurations. # Edit # 2021/04/26 added PIN/passphrase option for sapgenpse seclogin Wonderful information in a couple of blogs!! 2086829 SAP HANA Dynamic Tiering Sizing Ratios, Dynamic Tiering Hardware and Software Requirements, SAP Note 2365623 SAP HANA Dynamic Tiering: Supported Operating Systems, 2555629 SAP HANA 2.0 Dynamic Tiering Hypervisor and Cloud Support. In general, there is no needs to add site3 information in site1, vice versa. Please keep in mind to configure the correct default gateway with is/local_addr for stateful firewall connections. HANA XSA port specification via mtaext: SAP note 2389709 - Specifying the port for SAP HANA Cockpit before installation Needed PSE's and their usage. From Solution Manager 7.1 SP 14 on we support the monitoring of metrics on HANA instance-level and also have a template level for SAP HANA replication groups. Network for internal SAP HANA communication: 192.168.1. both the SAP HANA databases on the primary and the secondary site share the same license key, identified by the System Identifier (SID) and an automatically generated hardware key. 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 system, there are 2 configurable parameters. * wl -- wlan United States. Understood More Information interfaces similar to the source environment, and ENI-3 would share a common security group. So we followed the below steps: ALTER SYSTEM ALTER CONFIGURATION ( global.ini, SYSTEM ) SET( customizable_functionalities, dynamic_tiering ) = true. Dynamic tiering is embedded within SAP HANA operational processes, such as standby setup, backup and recovery, and system replication. Make sure It must have the same number of nodes and worker hosts. Or see our complete list of local country numbers. (Addition of DT worker host can be performed later). The certificate wont be validated which may violate your security rules. For more information, see Standard Permissions. documentation. when site2(secondary) is not working any longer. Are you already prepared for changing the server due to hardware change / OS upgrade with a virtual hostname concept? In Figure 10, ENI-2 is has its can use elastic network interfaces combined with security groups to achieve this network 2211663 . It differs for nearly each component which makes it pretty hard for an administrator.

A security group acts as a virtual firewall that controls the traffic for one or more -ssltrustcert have to be added to the call. 1. The host and port information are that of the SAP HANA dynamic tiering host. Maintain, reccomend and install SAP software for our client, including SAP Netweaver, ECC,R/3, APO and BW. The latest release version of DT is SAP HANA 2.0 SP05. Once the esserver service is assigned to a tenant database, the database, not SYSTEMDB, owns the service. For details how this is working, read this blog. For instance, third party tools like the backup tool via backint are affected. Single node and System Replication(2 tiers), 2. * Dedicated network for system replication: 10.5.1. If you change the HANA hostname resolution, you will map the physical hostname which represents your default gateway to the original installed vhostname. We are talk about signed certificates from a trusted root-CA. For more information, see Assigning Virtual Host Names to Networks. For your information, I copy sap note SAP HANA dynamic tiering adds the SAP HANA dynamic tiering service (esserver) to your SAP HANA system. Click more to access the full version on SAP for Me (Login required). If you plan to use storage connector APIs, you must configure the multipath.conf and global.ini files before installation. Usually system replication is used to support high availability and disaster recovery. # 2020/4/15 Inserted Vitaliys blog link + XSA diagnose details 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. mapping rule : internal_ip_address=hostname. must be backed up. We used NFS storage in our case which has following requirement: The actual architecture that we followed is as follows: Dedicated host deployment with /hana/shared/ mounted on both the hosts. Its purpose is to extend SAP HANA memory with a disk-centric columnar store (as opposed to the SAP HANA in-memory store). recovery. Here we talk about the client within the HANA client executable.

Internal communication channel configurations(Scale-out & System Replication). Accordingly, we will describe how to configure HANA communication channels, which HANA supports, with examples. The new rules are connect string to skip hostname validation: As always you can create an own certificate for the client and copy it to sapcli.pse instead of using the server sapsrv.pse. You may choose to manage your own preferences. Solution Secure Network Settings for Internal SAP HANA Services To avoid opening an attack vector in an SAP HANA system, it is necessary to configure the settings for internal service communication in the recommended way. After TIER2 full sync completed, triggered the TIER3 full sync Any ideas? Every label should have its own IP. DLM is part of the SAP HANA Data Warehousing Foundation option, which provides packaged tools for large scale SAP HANA use cases to support more efficient data management and distribution in an SAP HANA landscape. Copy the commands and deploy in SQL command. secondary. Log mode normal means that log segments are backed up. You can use SAP Landscape Management for
The bottom line is to make site3 always attached to site2 in any cases. Step 1. It must have the same system configuration in the system
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. You can also select directly the system view PSE_CERTIFICATES. Figure 11: Network interfaces and security groups. Another thing is the maintainability of the certificates. The secondary system must meet the following criteria with respect to the
