In the step 5, it is possible to avoid exporting and converting the keys. User Action: Investigate why connections are closed (for example, network problem) and resolve the issue. The secondary system must meet the following criteria with respect to the Another thing is the maintainability of the certificates. We're sorry we let you down. For the section [system_replication_hostname_resolution], you can add either all hosts or neighboring sites, but I am going to add only neighboring sites in order to remove all the configuration conflicts in below examples. Its purpose is to extend SAP HANA memory with a disk-centric columnar store (as opposed to the SAP HANA in-memory store). SAP HANA system replication is used to address SAP HANA outage reduction due to planned maintenance, fault, and disasters. 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. First time, I Know that the mapping of hostname to IP can be different on each host in system replication relationship. Step 1 . Unregisters a system replication site on a primary system.

EC2 instance in an Amazon Virtual Private Cloud (Amazon VPC). /hana/shared should be mounted on both the hosts namely HANA host and Dynamic Tiering host which will contain installation files of HANA and Dynamic Tiering service. Changes the replication mode of a secondary site. Wonderful information in a couple of blogs!! received on the loaded tables. mapping rule : internal_ip_address=hostname. You modify properties in the global.ini file to prepare resources on each tenant database to support SAP HANA dynamic tiering. 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. Since quite a while SAP recommends using virtual hostnames. There are two scripts: HANA_Configuration_MiniChecks* and HANA_Security_Certificates*. Starting point: * wl -- wlan As you may read between the lines Im not a fan of authorization concepts. Chat Offline. It must have a different host name, or host names in the case of Following parameters is set after configuring internal network between hosts. Network Configuration for SAP HANA system replication Contact Us Contact us Contact us 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. configure security groups, see the AWS documentation. You have installed and configured two identical, independently-operational. But keep in mind that jdbc_ssl parameter has no effect for Node.js applications! You have installed SAP Adaptive Extensions. 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?? collected and stored in the snapshot that is shipped. network interface, see the AWS isolation. Stop secondary DB. mapping rule : system_replication_internal_ip_address=hostname, 1. It's a hidden feature which should be more visible for customers. Which communication channels can be secured? If you've got a moment, please tell us what we did right so we can do more of it. The latest release version of DT is SAP HANA 2.0 SP05. Configuring SAP HANA Inter-Service Communication, Configuring Hostname Resolution for SAP HANA System Replication, Configuration for logical network separation, AWS Or see our complete list of local country numbers. If you have a HANA on one server construct which means an additional application server running with the central services running together with the HDB on the same server. 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. Internal communication is configured too openly For more information, see Assigning Virtual Host Names to Networks. SAP HANA and dynamic tiering each support NFS and SAN storage using storage connector APIs. Separating network zones for SAP HANA is considered an AWS and SAP best practice. You may choose to manage your own preferences. SAP User Role CELONIS_EXTRACTION in Detail. Therfore you need to specify all hosts of own site as well as neighboring sites. need not be available on the secondary system. (Storage API is required only for auto failover mechanism). To learn more about this step, see Amazon EBS-optimized instances can also be used for further isolation for storage I/O. Copyright | You have verified that the log_mode parameter in the persistence section of Post this, Installation of Dynamic Tiering License need to done via COCKPIT. Started the full sync to TIER2 For more information, see SAP Note 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. Pre-requisites. 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. Only set this to true if you have configured all resources with SSL. 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. 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. The required ports must be available. Figure 12: Further isolation with additional ENIs and security The OS process for the dynamic tiering host is hdbesserver, and the service name is esserver. Dynamic tiering option can be deployed in two ways: You can install SAP HANA and SAP HANA dynamic tiering each on a dedicated server (referred to as a dedicated host deployment) or on the same server (referred to as a same host deployment). On AS ABAP server this is controlled by is/local_addr parameter. You set up system replication between identical SAP HANA systems. Refresh the page and To Be Configured would change to Properly Configured. Most SAP documentations are for simple environments with one network interface and one IP label on it. After some more checks we identified the listeninterface and internal_hostname_resolution parameters were not updated on TIER2 and TIER3 Disables the preload of column table main parts. The BACKINT interface is available with SAP HANA dynamic tiering. Perform SAP HANA inter-node communication as well as SAP HSR network traffic. The extended store can reduce the size of your in-memory database. I just realized that the properties 'jdbc_ssl*' have been renamed to "hana_ssl" in XSA >=1.0.82. 2478769 Obtaining certificates with subject Alternative Name (SAN) within STRUST All mandatory configurations are also written in the picture and should be included in global.ini. Operators Detail, SAP Data Intelligence. An additional license is not required. General Prerequisites for Configuring SAP 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 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. You cant provision the same service to multiple tenants. Perform backup on primary. Dynamic tiering adds smart, disk-based extended storage to your SAP HANA database. mapping rule : internal_ip_address=hostname. Persistence encryption of the SAP HANA system is not available when dynamic tiering is installed. Dynamic tiering is also supported by the Data Lifecycle Manager (DLM), an SAP HANA XS-based tool to relocate data from SAP HANA memory to alternate storage locations such as the dynamic tiering extended store, SAP HANA extension nodes, or Hadoop/Vora. But the, SAP app server on same machine, tries to connect to mapped external hostname and if tails of course. 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 system. If set on SAP Host Agent must be able to write to the operations.d Share, Unregister Secondary Tier from System Replication, Unregister System Replication Site on It must have the same number of nodes and worker hosts. thank you for this very valuable blog series!

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. 1 step instead of 4 , Alerting is not available for unauthorized users, Right click and copy the link to share this comment, With XSA 1.0.82 (begin of 2018), SAP introduced new parameters (Check note, https://blogs.sap.com/2014/01/17/configure-abap-to-hana-ssl-connection/, 1761693 Additional CONNECT options for SAP HANA, 2475246 How to configure HANA DB connections using SSL from ABAP instance, Vitaliy Rudnytskiys blog: Secure connection from HDBSQL to SAP HANA Cloud, https://blogs.sap.com/2020/04/14/secure-connection-from-hdbsql-to-sap-hana-cloud/, Import certificate to HANA Cockpit (for client communication) [part II], Import certificate to HANA resource(s) [part II], Configure clients (AS ABAP, ODBC, etc.) Tip: use the integrated port reservation of the Host agent for all of your services, Possible values are: HANA,HANAREP,XSA,ABAP,J2EE,SUITE,ETD,MDM,SYBASE,MAXDB,ORACLE,DB2,TREX,CONTENTSRV,BO,B1, 401162 Linux: Avoiding TCP/IP port conflicts and start problems. (Addition of DT worker host can be performed later). 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 network. SAP is using mostly one certificate for all components (host agent, DAA, SystemDB, Tenant) which belongs to the physical hostname (systempki). If you plan to use storage connector APIs, you must configure the multipath.conf and global.ini files before installation. 2487731 HANA Basic How-To Series HANA and SSL CSR, SIGN, IMPLEMENT (pse container ) for ODBC/JDBC connections. 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. Checks whether the HA/DR provider hook is configured. For instance, you have 10.0.1. For more information, see Standard Roles and Groups. Step 3. If set on the primary system, the loaded table information is Pre-requisites. When set, a diamond appears in the database column. In this case, you are required to add additional NIC, ip address and cabling for site1-3 replication. Figure 10: Network interfaces attached to SAP HANA nodes. Darryl Griffiths Blog from 2014 SAP HANA SSL Security Essential Introduction. ALTER SYSTEM ALTER CONFIGURATION ( global.ini, SYSTEM ) SET( customizable_functionalities, dynamic_tiering ) = true. Here you can reuse your current automatism for updating them. Here we talk about the client within the HANA client executable. +1-800-872-1727.
