When set, a diamond appears in the database column. You need a minimum SP level of 7.2 SP09 to use this feature. instances. Introduction. Set Up System Replication with HANA Studio. Internal communication channel configurations(Scale-out & System Replication), Part2. Figure 10: Network interfaces attached to SAP HANA nodes. Determine which format your key file has with a look into it: If it is a PKCS#12 format you have to follow this steps (there are several ways, just have a look at the openssl documentation): a) Export the keys in PKCS#12 transfer format: The HANA DB has to be online. The systempki should be used to secure the communication between internal components. If you want to force all connection to use SSL/TLS you have to set the sslenforce parameter to true (global.ini). 1761693 Additional CONNECT options for SAP HANA SAP HANA System Target Instance. It must have the same number of nodes and worker hosts. the same host is not supported. We are actually considering the following scenarios: mapping rule : system_replication_internal_ip_address=hostname, 1. Click more to access the full version on SAP for Me (Login required). To use the Amazon Web Services Documentation, Javascript must be enabled. (Storage API is required only for auto failover mechanism). This will speed up your login instead of using the openssl variant which you discribed. This optimization provides the best performance for your EBS volumes by global.ini -> [system_replication_hostname_resolution] : is deployed. If you've got a moment, please tell us what we did right so we can do more of it. Which communication channels can be secured? The secondary system must meet the following criteria with respect to the documentation. Trademark. To give context - We are using HANA SSL certificates, which are valid for 1 year and before it gets expire we need to renew it, so we want to do Monitoring to get alerts of it either by Cockpit/ Splunk or other home grown tools via Perl/any other scripting, so any one knows more about it?? Understood More Information with Tenant Databases. For your information, I copy sap note This section describes operations that are available for SAP HANA instances. SAP is using mostly one certificate for all components (host agent, DAA, SystemDB, Tenant) which belongs to the physical hostname (systempki). Scale out of dynamic tiering is not available. SAP HANA Network Requirements Contact Us Contact us Contact us Home This site uses cookies and related technologies, as described in our privacy statement, for purposes that may include site operation, analytics, enhanced user experience, or advertising. The primary hosts listen on the dedicated ports of the separate network only, and incoming requests on the public interfaces are rejected. One aspect is the authentication and the other one is the encryption (client+server data + communication channels). SAP HANA Security Techical whitepaper ( 03 / 2021), HANA XSA port specification via mtaext: SAP note 2389709 Specifying the port for SAP HANA Cockpit before installation, It is now possible to deactivate the SLD and using the LMDB as leading data collection system. In multiple-container systems, the system database and all tenant databases It would be difficult to share the single network for system replication. Internal Network Configurations in System Replication : There are also configurations you can consider changing for system replications. global.ini -> [communication] -> listeninterface : .global or .internal The below diagram depicts better understanding of internal networks: The status after internal network configuration: Once the listener interface has communication method internal, the two hosts (HANA & DT hosts) can communicate securely and their internal IP addresses reflects in parameter -> internal_hostname_resolution, Installation of Dynamic Tiering Component. Following parameters is set after configuring internal network between hosts. If set on the primary system, the loaded table information is Certificate Management in SAP HANA We continue to fully maintain the SP05 version and deliver PL releases as necessary but there are no plans to release newer SP versions for DT. Secondary : Register secondary system. It must have the same system configuration in the system And you need to change the parameter [communication]->listeninterface to .internal and add internal network entries as followings. * en -- ethernet communications. 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 Each node has at least 2 physical IP addresses, one is for external network and another is for internal network where data/intermediate results for query processing/database operations can move around. For scale-out deployments, configure SAP HANA inter-service communication to let communication, and, if applicable, SAP HSR network traffic. The cleanest way is the Golden middle option 2. You modify properties in the global.ini file to prepare resources on each tenant database to support SAP HANA dynamic tiering. One question though - May i know how are you Monitoring this SSL Certificates, which are applied on HANA DB ? Otherwise, the system performance or expected response time might not be guaranteed due to the limited network bandwidth. Updates parameters that are relevant for the HA/DR provider hook. more about security groups, see the AWS An elastic network interface is a virtual network interface that you can attach to an Network Configuration for SAP HANA System Replication (HSR) You can configure additional network interfaces and security groups to further isolate inter-node communication as well as SAP HSR network traffic. In the following example, ENI-1 of each instance shown is a member Replication, Start Check of Replication Status On existing HANA DB host we already have two file systems for DATA and LOG: On Dynamic Tiering Host the following file systems are required which will store ES data and logs: So after the above setup the actual architecture will appear as follows: Communication channel and network requirements. Any changes made manually or by to use SSL [part II], Configure HDB parameters for high security [part II], Configure XSA with TLS and cipher for high security [part II], Import certificate to host agent [part II], Pros and Cons certification collections [part II], Will show your certificate for your domain(s), Check the certificate: sapgenpse get_my_name -p cert.pse, Replace the sapsrv.pse, SAPSSLS.pse and SAPSSLC.pse with the created cert.pse, the application server connection via SQLDBC have to set up to be secure, HANA Cockpit connections have to set up to be secure, Local hdbsql connections have to be set up for encryption, sslValidateCertificate = false => will not validate the certificate, sslHostNameInCertificate = => will overwrite the calling hostname, configure the hostname mapping inside the HANA, the other one to copy the sapsrv.pse to the sapcli.pse, Create the certificate on base of the vhostname of the server, Copy the *.pse as SAPSSLS.pse to /usr/sap/hostctrl/exe/sec/, use sapgenpse seclogin option as root (with proper environment means SECUDIR variable) when you have specified a PIN/passphrase, inside the database => certificate collection. Do you have similar detailed blog for for Scale up with Redhat cluster. Step 3. If you raise the isolation level to high after the fact, the dynamic tiering service stops working. The host name specified here is used to verify the identity of the server instead of the host name with which the connection was established. As promised here is the second part (practical one) of the series about the secure network communication. Configuring SAP HANA Inter-Service Communication, Configuring Hostname Resolution for SAP HANA System Replication, Configuration for logical network separation, AWS Dynamic tiering enhances SAP HANA with large volume, warm data management capability. But keep in mind that jdbc_ssl parameter has no effect for Node.js applications! properties files (*.ini files). before a commit takes place on the local primary system. Provisioning fails if the isolation level is high. +1-800-872-1727. System replication cannot be used in SAP HANA systems in which dynamic tiering is enabled. own security group (not shown) to secure client traffic from inter-node communication. when site2(secondary) is not working any longer. System replication between two systems on Run hdblcm (with root) with the path of extracted software as parameter and install dynamic tiering component without addition of DT host. All tenant databases running dynamic tiering share the single dynamic tiering license. About this page This is a preview of a SAP Knowledge Base Article. Wanting to use predictable network device names in a custom way is going, * Two character prefixes based on the type of interface: This is normally the public network. The host and port information are that of the SAP HANA dynamic tiering host. You have assigned the roles and groups required. 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. Its purpose is to extend SAP HANA memory with a disk-centric columnar store (as opposed to the SAP HANA in-memory store). Assignment of esserver is done by below sql script: ALTER DATABASE ADD esserver [ AT [ LOCATION] [: ] ]. 2386973 - Near Zero DowntimeUpgradesforHANADatabase 3-tierSystemReplication. It must have a different host name, or host names in the case of number. to use SSL [, Configure HDB parameters for high security [, Pros and Cons certification collections [, HANA Cockpit (HTTPS)=> sapcontrol (SAP Start Service / sapstartsrv), HANA Cockpit (JDBC) => Database Explorer / Monitoring => Resources, Native Client Connection (ODBC/JDBC) => HANA. Thanks a lot for sharing this , it's a excellent blog . Is it possible to switch a tenant to another systemDB without changing all of your client connections? Since quite a while SAP recommends using virtual hostnames. Refresh the page and To Be Configured would change to Properly Configured. we are planning to have separate dedicated network for multiple traffic e.g. You can also encrypt the communication for HSR (HANA System replication). Both SAP HANA and dynamic tiering hosts have their own dedicated storage. Javascript is disabled or is unavailable in your browser. Are you already prepared with multiple interfaces (incl.
