SAP HANA System Target Instance. Step 2. In this case, you are required to add additional NIC, ip address and cabling for site1-3 replication. Any ideas? Considering the potential failover/takeover for site1 and site2, that is, site1 and site2 actually should have the same position. The secondary system must meet the following criteria with respect to the Follow the Disables system replication capabilities on source site. mapping rule : system_replication_internal_ip_address=hostname, 1. We are talk about signed certificates from a trusted root-CA. By default, on every installation the system gets a systempki (self-signed) until you import an own certificate. 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. the secondary system, this information is evaluated and the no internal interface found, listeninterface, .internal , KBA , HAN-DB , SAP HANA Database , Problem . (details see part I). Every label should have its own IP. Conversely, on the AWS Cloud, you Network for internal SAP HANA communication between hosts at each site: 192.168.1. Use Secure Shell (SSH) to connect to your EC2 instance at the OS level. One aspect is the authentication and the other one is the encryption (client+server data + communication channels). An elastic network interface is a virtual network interface that you can attach to an 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.

When set, a diamond appears in the database column. steps described in the appendix to configure Introduction. 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 Thanks for the further explanation. 2478769 Obtaining certificates with subject Alternative Name (SAN) within STRUST Net2Source Inc. is an award-winning total workforce solutions company recognized by Staffing Industry Analysts for our accelerated growth of 300% in the last 3 years with over 5500+ employees . Failover nodes mount the storage as part of the failover process. Not sure up to which revision the "legacy" properties will work. Most will use it if no GUI is available (HANA studio / cockpit) or paired with hdbuserstore as script automatism (housekeeping). It must have the same software version or higher. Internal communication channel configurations(Scale-out & System Replication), Part2. 1761693 Additional CONNECT options for SAP HANA By default, this enables security and forces all resources to use ssl. Understood More Information Replication, Register Secondary Tier for System 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. All tenant databases running dynamic tiering share the single dynamic tiering license. 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. Multiple interfaces => one or multiple labels (n:m). (check SAP note 2834711). 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. Have you identified all clients establishing a connection to your HANA databases? Introduction. Thank you Robert for sharing the current developments on "DT", Alerting is not available for unauthorized users, Right click and copy the link to share this comment. There are two scripts: HANA_Configuration_MiniChecks* and HANA_Security_Certificates*. You can configure additional network interfaces and security groups to further isolate Surprisingly the TIER3 system replication status did not show up on the Replication monitor in HANA studio 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. SQLDBC is the basis for most interfaces; however, it is not used directly by applications. resolution is working by creating entries in all applicable host files or in the Domain savepoint (therefore only useful for test installations without backup and network interfaces you will be creating. To detect, manage, and monitor SAP HANA as a 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. Wonderful information in a couple of blogs!! On every installation of an SAP application you have to take care of this names. ALTER SYSTEM ALTER CONFIGURATION ( global.ini, SYSTEM ) SET( customizable_functionalities, dynamic_tiering ) = true. SAP HANA dynamic tiering is an integrated component of the SAP HANA database and cannot be operated independently from SAP HANA. For those who are not familiar with JDBC/ODBC/SQLDBC connections a short excursion: This was the first part as preparation for the next part the practical one. If this is not possible, because it is a mounted NFS share, SAP HANA SSFS Master Encryption Key The SSFS master encryption key must be changed in accordance with SAP Note 2183624. global.ini -> [system_replication_communication] -> listeninterface : .global or .internal Stay healthy, 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. We are not talking about self-signed certificates. # 2021/04/06 Inserted possibility for multiple SAN in one request / certificate with sapgenpse Starts checking the replication status share. Following parameters is set after configuring internal network between hosts. system. thank you for this very valuable blog series! groups. Another thing is the maintainability of the certificates. Dynamic tiering is targeted at SAP HANA database sizes of 512 GB and larger, where large data volumes begin to necessitate a data lifecycle management solution. On AS ABAP server this is controlled by is/local_addr parameter. The latest release version of DT is SAP HANA 2.0 SP05.
