as in a separate communication channel for storage. Questo articolo descrive come distribuire un sistema SAP HANA a disponibilit elevata in una configurazione con scalabilit orizzontale. If you plan to use storage connector APIs, you must configure the multipath.conf and global.ini files before installation. Scale-out and System Replication(2 tiers), 4. Persistence encryption of the SAP HANA system is not available when dynamic tiering is installed. Or see our complete list of local country numbers. If you change the HANA hostname resolution, you will map the physical hostname which represents your default gateway to the original installed vhostname. If you want to force all connection to use SSL/TLS you have to set the sslenforce parameter to true (global.ini). own security group (not shown) to secure client traffic from inter-node communication. Are you already prepared with multiple interfaces (incl. if no mappings specified(Default), the default network route is used for system replication communication. Configure SAP HANA hostname resolution to let SAP HANA communicate over the If you raise the isolation level to high after the fact, the dynamic tiering service stops working. Below query returns the internal hostname which we will use for mapping rule. received on the loaded tables. There can be only one dynamic tiering worker host for theesserver process. An optional add-on to the SAP HANA database for managing less frequently accessed warm data. 2478769 Obtaining certificates with subject Alternative Name (SAN) within STRUST alter system alter configuration ('xscontroller.ini','SYSTEM') set ('communication','jdbc_ssl') = 'true' with reconfigure; You can use the same procedure for every other XSA installation. It would be difficult to share the single network for system replication. need not be available on the secondary system. System replication between two systems on global.ini -> [communication] -> listeninterface : .global or .internal Disables the preload of column table main parts. Replication, Start Check of Replication Status General Prerequisites for Configuring SAP Single node and System Replication(3 tiers)", for example, is that right? a distributed system. Single node and System Replication(2 tiers), 2. Because site1 and site2 usually resides in the same data center but site3 is located very far in another data center. The same instance number is used for groups. 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. The connection parameters for ODBC-based connections can also be used to configure TLS/SSL for connections from ABAP applications to SAP HANA using the SAP Database Shared Library (DBSL). You just have to set the dbs/hdb/connect_property parameter to the correct value: In some cases, you may receive an error if you force the use of TLS/SSL: You have to set some tricky parameter due to the default gateway of the Linux server. How you can secure your system with less effort? Contact us. SAP HANA and dynamic tiering each support NFS and SAN storage using storage connector APIs. Perform SAP HANA DT service can be checked from OS level by command HDB info. There are two scripts: HANA_Configuration_MiniChecks* and HANA_Security_Certificates*. Refresh the page and To Be Configured would change to Properly Configured. The parameter listeninterface=.global in the section [system_replication_communication] is used for system replication. If you have to install a new OS version you can setup your new environment and switch the application incl. For more information, see Assigning Virtual Host Names to Networks. Provisioning fails if the isolation level is high. We are not talking about self-signed certificates. If set on Early Watch Alert shows a red alert at section "SAP HANA Network Settings for System Replication Communication (listeninterface)": enable_ssl, system_replication_communication, global.ini, .global, TLS, encrypted communication expected, when, off, listeninterface , KBA , HAN-DB-SEC , SAP HANA Security & User Management , HAN-DB , SAP HANA Database , SV-SMG-SER-EWA , EarlyWatch Alert , HAN-DB-HA , SAP HANA High Availability (System Replication, DR, etc.) More recently, we implemented a full-blown HANA in-memory platform .

When complete, test that the virtual host names can be resolved from An additional license is not required. After TIER2 full sync completed, triggered the TIER3 full sync And you need to change the parameter [communication]->listeninterface to .internal and add internal network entries as followings. Use Secure Shell (SSH) to connect to your EC2 instance at the OS level. interfaces similar to the source environment, and ENI-3 would share a common security group. 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. system. labels) and the suitable routing for a stateful connection for your firewall rules and network segmentation. Be careful with setting these parameters! In multiple-container systems, the system database and all tenant databases It is also important to configure the appropriate network communication routing, because per default every traffic on a Linux server goes per default over the default gateway which is by default the first interface eth0 (we will need this know how later for the certificates). This section describes operations that are available for SAP HANA instances. instances. In most case, tier 1 and tier 2 are in sync/syncmem for HA purepose, while tier 3 is used for DR. Once again from part I which PSE is used for which service: SECUDIR=/usr/sap//HDBxx//sec. Create virtual host names and map them to the IP addresses associated with client, SAP HANA Network and Communication Security Attach the network interfaces you created to your EC2 instance where SAP HANA is number. Search for jobs related to Data provisioning in sap hana or hire on the world's largest freelancing marketplace with 22m+ jobs.

The certificate wont be validated which may violate your security rules. More and more customers are attaching importance to the topic security. 3. So we followed the below steps: You can also select directly the system view PSE_CERTIFICATES. Though it's definitely not easy to go with so much secure setup for even an average complex landscape, hoping there will be a day when there would be a single instance for everything and hits on this blog would go sky-high , I just published mine https://blogs.sap.com/2020/04/14/secure-connection-from-hdbsql-to-sap-hana-cloud/ and now seeing yours But where you use -sslcertrust I dig deeper how to make sure HANA server authentication works from hdbsql , Great post Vitaliy! Using command line tool hdbnsutil: Primary : You can use the SQL script collection from note 1969700 to do this. In this example, the target SAP HANA cluster would be configured with additional network Contact us. 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. that the new network interfaces are created in the subnet where your SAP HANA instance when site2(secondary) is not working any longer. 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. For more information about network interfaces, see the AWS documentation. We are talk about signed certificates from a trusted root-CA. shipping between the primary and secondary system. Internal communication is configured too openly Your application automatically determines which tier to save data to: the SAP HANA in-memory store (the hot store), or extended storage (the warm store). database, ensure the following: To allow uninterrupted client communication with the SAP HANA Set Up System Replication with HANA Studio.

An elastic network interface is a virtual network interface that you can attach to an By default, on every installation the system gets a systempki (self-signed) until you import an own certificate. synchronous replication from memory of the primary system to memory of the secondary system, because it is the only method which allows the pacemaker cluster to make decisions based on the implemented algorithms. 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. Unregisters a secondary tier from system replication. Alerting is not available for unauthorized users, Right click and copy the link to share this comment. connection recovery after disaster recovery with network-based IP Setting Up System Replication You set up system replication between identical SAP HANA systems. * wl -- wlan Run hdblcm (with root) with the path of extracted software as parameter and install dynamic tiering component without addition of DT host. SAP Host Agent must be able to write to the operations.d 2. Checks whether the HA/DR provider hook is configured. For your information, I copy sap note As you create each new network interface, associate it with the appropriate provide additional, dedicated capacity for Amazon EBS I/O. Enables a site to serve as a system replication source site. Ensures that a log buffer is shipped to the secondary system need to specify all hosts of own site as well as neighboring sites. Are you already prepared for changing the server due to hardware change / OS upgrade with a virtual hostname concept? SAP HANA Tenant Database . The instance number+1 must be free on both can use elastic network interfaces combined with security groups to achieve this network Both SAP HANA and dynamic tiering hosts, including standby hosts, use storage APIs to access the devices. Chat Offline. reason: (connection refused). Binds the processes to this address only and to all local host interfaces. Now you have to go to the HANA Cockpit Manager to change the registered resource to use SSL. no internal interface found, listeninterface, .internal , KBA , HAN-DB , SAP HANA Database , Problem . ENI-3 # Edit 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. Started the full sync to TIER2 replication network for SAP HSR. if mappings are specified as either neighboring sites(minimum) or all hosts of own site as well as neighboring sites, an internal(separate) network is used for system replication communication. We can install DLM using Hana lifecycle manager as described below: Click on to be configured. If you set jdbc_ssl to true will lead to encrypt all jdbc communications (e.g. mapping rule : internal_ip_address=hostname. Public communication channel configurations, 2. Figure 11: Network interfaces and security groups. EC2 instance in an Amazon Virtual Private Cloud (Amazon VPC). Primary Host: Enable system replication. Scenario : we have 3 nodes scale-out landscape setup and in order to communicate with all participants in the landscape, additional IP addresses are required in your production site. Therfore you In system replication, the secondary SAP HANA system is an exact copy of the active primary system, with the same number of active hosts in each system. 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. Multiple interfaces => one or multiple labels (n:m). You have installed SAP Adaptive Extensions. To learn more about this step, see Configuring Hostname Resolution for SAP HANA System Replication in the SAP Starting point: So, the easiest way is to use the XSA set-certificate command: Afterwards check your system with the diagnose function. For more information, see SAP HANA Database Backup and Recovery. You add rules to each security group that allow traffic to or from its associated implies that if there is a standby host on the primary system it 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.

All tenant databases running dynamic tiering share the single dynamic tiering license. network interface, see the AWS The backup directories for both SAP HANA and dynamic tiering reside on a shared file system, allowing SAP HANA access to the dynamic tiering backup files. Conversely, on the AWS Cloud, you One question though - May i know how are you Monitoring this SSL Certificates, which are applied on HANA DB ? Find SAP product documentation, Learning Journeys, and more. SAP HANA communicate over the internal network. global.ini -> [communication] -> listeninterface : .global or .internal For more information, see SAP Note inter-node communication as well as SAP HSR network traffic. The primary hosts listen on the dedicated ports of the separate network only, and incoming requests on the public interfaces are rejected. 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 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. 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. 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.
