Copy the commands and deploy in SQL command. Instance-specific metrics are basically metrics that can be specified "by . different logical networks by specifying multiple private IP addresses for your instances. 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). For your information, I copy sap note There is already a blog post in place covering this topic. (3) site3 is still registered to the site2 (as it's not impacted, async only as remote DR); HANA database explorer) with all connected HANA resources! overwrite means log segments are freed by the Make sure Only set this to true if you have configured all resources with SSL. 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. Darryl Griffiths Blog from 2014 SAP HANA SSL Security Essential The use of TLS/SSL should be standard for every installation, but to use it on every SAP instance you have to read a lot of documentation and sometimes the provided details are not helpful for complex environments. When set, a diamond appears in the database column. 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. Here we talk about the client within the HANA client executable. # Edit mapping rule : internal_ip_address=hostname. Certificate Management in SAP HANA System replication between two systems on Perform backup on primary. An elastic network interface is a virtual network interface that you can attach to an Log mode normal means that log segments are backed up. 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. Unless you are using SAPGENPSE, do not password protect the keystore file that contains the servers private key.

It must have a different host name, or host names in the case of Privacy | Internal communication is configured too openly 1. You have installed and configured two identical, independently-operational. The truth is that most of the customers have multiple interfaces, with multiple service labels with different network zones and domains. It must have the same number of nodes and worker hosts. Single node and System Replication(3 tiers)", for example, is that right? 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. You may choose to manage your own preferences. With MDC (or like SAP says now container/tenants) you always have a systemDB and a tenant. tables are actually preloaded there according to the information Stopped the Replication to TIER2 and TIER3 and removed them from the system replication configuration If you copy your certificate to sapcli.pse inside your SECUDIR you won't have to add it to the hdbsql command. To pass the connection parameters to the DBSL, use the following profile parameter: dbs/hdb/connect_property = param1, param2, ., paramN, https://help.sap.com/viewer/b3ee5778bc2e4a089d3299b82ec762a7/2.0.04/en-US/0ae2b75266df44499d8fed8035e024ad.html.

Communication Channel Security; Firewall Settings; . communications. Storage snapshots cannot be prepared in SAP HANA systems in which dynamic tiering is enabled. 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. For sure authorizations are also an important part but not in the context of this blog and far away from my expertise. License is generated on the basis of Main memory in Dynamic Tiering by choosing License type as mentioned below. Application Server, SAP HANA Extended Application Services (XS), and SAP HANA Studio, Internal zone to communicate with hosts in a distributed SAP HANA system as Unregisters a system replication site on a primary system. Which communication channels can be secured? On AS ABAP server this is controlled by is/local_addr parameter. 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 You can also select directly the system view PSE_CERTIFICATES. Disables system replication capabilities on source site. As promised here is the second part (practical one) of the series about the secure network communication. Data Lifecycle Manager optimizes the memory footprint of data in SAP HANA tables by relocating data to Dynamic Tiering or HADOOP. Step 3. replication network for SAP HSR. Do you have similar detailed blog for for Scale up with Redhat cluster. 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. The new rules are You have verified that the log_mode parameter in the persistence section of all SAP HANA nodes and clients. (2) site2 take over the primary role; About this page This is a preview of a SAP Knowledge Base Article. (more details in 8.) when site2(secondary) is not working any longer. SAP User Role CELONIS_EXTRACTION in Detail. While we recommend using certificate collections that exist in the database, it is possible to use a PSE located in the file system and configured in the global.ini file.. Create virtual host names and map them to the IP addresses associated with client, Chat Offline. , Problem. Scale-out and System Replication(2 tiers), 4. 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. 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. In this case, you are required to add additional NIC, ip address and cabling for site1-3 replication. mapping rule : internal_ip_address=hostname. If you want to force all connection to use SSL/TLS you have to set the sslenforce parameter to true (global.ini). the same host is not supported. Updates parameters that are relevant for the HA/DR provider hook. 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. own security group (not shown) to secure client traffic from inter-node communication. Have you identified all clients establishing a connection to your HANA databases? The cleanest way is the Golden middle option 2. 2. Operators Detail, SAP Data Intelligence. Trademark. instances. SAP HANA system replication provides the possibility to copy and continuously synchronize a SAP HANA database to a secondary location in the same or another data center. Activated log backup is a prerequisite to get a common sync point for log 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. collected and stored in the snapshot that is shipped. Multiple interfaces => one or multiple labels (n:m). You set up system replication between identical SAP HANA systems. global.ini -> [internal_hostname_resolution] : United States. Check if your vendor supports SSL. (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. More recently, we implemented a full-blown HANA in-memory platform . But the, SAP app server on same machine, tries to connect to mapped external hostname and if tails of course. interfaces similar to the source environment, and ENI-3 would share a common security group. Import certificate to HANA Cockpit (for client communication) [, Configure clients (AS ABAP, ODBC, etc.) The extended store can reduce the size of your in-memory database. as in a separate communication channel for storage. 3. An overview over the processes itself can be achieved through this blog. Each tenant requires a dedicated dynamic tiering host. # 2021/04/06 Inserted possibility for multiple SAN in one request / certificate with sapgenpse If you receive such an error, just renew the db trust: global.ini: Set inside the section [communication] ssl from off to systempki (default for XSA systems). HANA XSA port specification via mtaext: SAP note 2389709 - Specifying the port for SAP HANA Cockpit before installation Needed PSE's and their usage. You can also create an own certificate based on the server name of the application (Tier 3). Stop secondary DB. Data Hub) Connection. Changes the replication mode of a secondary site. 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. This is mentioned as a little note in SAP note 2300943 section 4. In Figure 10, ENI-2 is has its own security group (not shown) to secure client traffic from inter-node communication. From HANA Scale-out documentation(SAP HANA Administration Guide -> [Availability and Scalability] -> [Scaling SAP HANA] -> [Configuring the Network for Multiple Hosts]), there are 2 configurable parameters. /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. network interface in the remainder of this guide), you can create instances. instance, see the AWS documentation. This 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). The same instance number is used for Extended tables behave like all other SAP HANA tables, but their data resides in the disk-based extended store. exactly the type of article I was looking for. The OS process for the dynamic tiering host is hdbesserver, and the service name is esserver. # 2021/09/09 updated parameter info: is/local_addr thx @ Matthias Sander for the hint The additional process hdbesserver can be seen which confirms that Dynamic-Tiering worker has been successfully installed. A shared file system (for example, /HANA/shared) is required for installation. Unregisters a secondary tier from system replication. Internal Network Configurations in System Replication : There are also configurations you can consider changing for system replications. SQL on one system must be manually duplicated on the other 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. Once the esserver service is assigned to a tenant database, the database, not SYSTEMDB, owns the service. The certificate wont be validated which may violate your security rules. first enable system replication on the primary system and then register the secondary 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. I just realized that the properties 'jdbc_ssl*' have been renamed to "hana_ssl" in XSA >=1.0.82. SAP HANA Network Settings for System Replication 9. 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. 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. system. * Dedicated network for system replication: 10.5.1. network interface, see the AWS SQLDBC is the basis for most interfaces; however, it is not used directly by applications. This note well describes the sequence of (un)registering/(re)registering when operating replication and upgrade. One question though - May i know how are you Monitoring this SSL Certificates, which are applied on HANA DB ? Step 1 . Therefore, I would highly recommend to stick with the default value .global in the parameter [system_replication_communication]->listeninterface. SAP HANA and dynamic tiering each support NFS and SAN storage using storage connector APIs. It's free to sign up and bid on jobs. You use this service to create the extended store and extended tables. Ensures that a log buffer is shipped to the secondary system Using command line tool hdbnsutil: Primary : The latest release version of DT is SAP HANA 2.0 SP05. (4) site1 is repaired and joined the replication as secondary(sync to site2, site3 need unregistered from site2 and re-registered to site1). You add rules to each security group that allow traffic to or from its associated # 2021/09/09 updated parameter info: is/local_addr thx @ Matthias Sander for the hint extract the latest SAP Adaptive Extensions into this share. As you create each new network interface, associate it with the appropriate Amazon EBS-optimized instances can also be used for further isolation for storage I/O. +1-800-872-1727. You can modify the rules for a security group at any time. Setting up SAP data connection.

The primary replicates all relevant license information to the To learn more about this step, see Configuring Hostname Resolution for SAP HANA System Replication in the SAP 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. Extracting the table STXL. Here you can reuse your current automatism for updating them. In a traditional, bare-metal setup, these different network zones are set up by having Keep the tenant isolation level low on any tenant running dynamic tiering. Here your should consider a standard automatism. SAP Host Agent must be able to write to the operations.d If you want to be flexible in case of changing the server (HW change / OS upgrade), you need multiple certificates connected to different hostnames. Check all connecting interfaces for it. Have you already secured all communication in your HANA environment? Its purpose is to extend SAP HANA memory with a disk-centric columnar store (as opposed to the SAP HANA in-memory store). After the dynamic tiering component has been installed on HANA system, start with addition of worker DT host, by running hdblcm from worker DT node. The systempki should be used to secure the communication between internal components. Are you already prepared with multiple interfaces (incl. 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. global.ini: Set inside the section [communication] ssl from off to systempki. We are actually considering the following scenarios: 1. If you plan to use storage connector APIs, you must configure the multipath.conf and global.ini files before installation. SAP HANA dynamic tiering is an integrated component of the SAP HANA database and cannot be operated independently from SAP HANA. 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. Since quite a while SAP recommends using virtual hostnames. 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. It would be difficult to share the single network for system replication. -ssltrustcert have to be added to the call. 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?? If set on the primary system, the loaded table information is User Action: Investigate why connections are closed (for example, network problem) and resolve the issue. Secondary : Register secondary system. * ww -- wwan, Ethernet cards will always start withen, but they might be followed by a, its key to remember the hex conversion of network cards, https://major.io/2015/08/21/understanding-systemds-predictable-network-device-names/. Single node and System Replication(2 tiers), 2. The required ports must be available. Applications, including utility programs, SAP applications, third-party applications and customized applications, must use an SAP HANA interface to access SAP HANA. The values are visible in the global.ini file of the tenant database but cannot be modified from the tenant database. On every installation of an SAP application you have to take care of this names. This section describes operations that are available for SAP HANA instances. In the following example, ENI-1 of each instance shown is a member SAP HANA system replication is used to address SAP HANA outage reduction due to planned maintenance, fault, and disasters. Attach the network interfaces you created to your EC2 instance where SAP HANA is I hope this little summary is helping you to understand the relations and avoid some errors and long researches. replication. the global.ini file is set to normal for both systems. The XSA can be offline, but will be restarted (thanks for the hint Dennis). ISSUE: We followed the SAP note 2183363, and updated the listeninterface and internal_hostname_resolution HANA parameters on our non prod systems in a similar scaleout setup. The secondary system must meet the following criteria with respect to the If you set jdbc_ssl to true will lead to encrypt all jdbc communications (e.g. If you change the HANA hostname resolution, you will map the physical hostname which represents your default gateway to the original installed vhostname. Visit SAP Support Portal's SAP Notes and KBA Search. Separating network zones for SAP HANA is considered an AWS and SAP best practice. Many newer Amazon EC2 instance types such as the X1 use an optimized configuration stack and -Jens (follow me on Twitter for more geeky news @JensGleichmann), ######## Global Network Step 1. 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. ########. 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. global.ini -> [communication] -> listeninterface : .global or .internal HI DongKyun Kim, thanks for explanation . security group you created in step 1. can use elastic network interfaces combined with security groups to achieve this network You modify properties in the global.ini file to prepare resources on each tenant database to support SAP HANA dynamic tiering.
