In my opinion, the described configuration is only needed below situations. HANA System Replication, SAP HANA System Replication Unless you are using SAPGENPSE, do not password protect the keystore file that contains the servers private key. The primary hosts listen on the dedicated ports of the separate network only, and incoming requests on the public interfaces are rejected. internal, and replication network interfaces. And you need to change the parameter [communication]->listeninterface to .internal and add internal network entries as followings. Are you already prepared for changing the server due to hardware change / OS upgrade with a virtual hostname concept? Considering the potential failover/takeover for site1 and site2, that is, site1 and site2 actually should have the same position. Step 2. The new rules are We are talk about signed certificates from a trusted root-CA. We're sorry we let you down. A service in this context means if you have multiple services like multiple tenants on one server running. I see more alerts in the trace files, don't know if they are related: [178728]{419183}[119/-1] 2015-08-18 20:56:11.225670 e cePlanExec cePlanExecutor.cpp(07183) : Error during Plan execution of model _SYS_STATISTICS:_SYS_SS_CE_1402084_140190768844608_4_INS (-1), reason: executor: plan operation failed;CalculationNode ($$_SYS_SS2_RESULT$$) -> operation (CustomLOp):Compilation failed; OpenChannelException at network layer: message: an error occured while opening the channel, [42096]{-1}[-1/-1] 2015-08-18 18:45:18.355758 e TrexNet EndPoint.cpp(00260) : ERROR: failed to open channel 127.0.0.1:30107!

So site1 & site3 won't meet except the case that I described. # 2021/04/26 added PIN/passphrase option for sapgenpse seclogin Multiple interfaces => one or multiple labels (n:m). Once the esserver service is assigned to a tenant database, the database, not SYSTEMDB, owns the service. For your information, having internal networks under scale-out / system replication is a mandatory configuration in your production sites. You use this service to create the extended store and extended tables. License is generated on the basis of Main memory in Dynamic Tiering by choosing License type as mentioned below. first enable system replication on the primary system and then register the secondary We know for step(4), there could be one more takeover, and then site1 will become new primary, but since site1 and site2 has the same capacity, it's not necessary to introduce one more short downtime for production, right? installed. savepoint (therefore only useful for test installations without backup and received on the loaded tables. 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. * You have installed internal networks in each nodes. For this it may be wise to add an IP label, which means an own DNS record with name and IP, for each service. You can also encrypt the communication for HSR (HANA System replication). 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. The OS process for the dynamic tiering host is hdbesserver, and the service name is esserver.

Have you already secured all communication in your HANA environment? 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. with Tenant Databases. Perform SAP HANA The additional process hdbesserver can be seen which confirms that Dynamic-Tiering worker has been successfully installed. At the time of the parameters change in Production both TIER2 and TIER3 systems were stopped and removed from Replication setup System replication cannot be used in SAP HANA systems in which dynamic tiering is enabled. implies that if there is a standby host on the primary system it thank you for this very valuable blog series! Below query returns the internal hostname which we will use for mapping rule. 2475246 How to configure HANA DB connections using SSL from ABAP instance. These are all pretty broad topic and for now we will focus on the x.509 certificates for encryption of the communication channels between server and clients. So I think each host, we need maintain two entries for "2. An optional add-on to the SAP HANA database for managing less frequently accessed warm data. we are planning to have separate dedicated network for multiple traffic e.g. 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. For more information, see Standard Permissions. After a validation on the non prod systems the change was made on our Production landscape that is using the HANA System Replication (HSR) You can copy the certificate of the HANA database to the application server but you dont need to (HANA on one Server Tier 2). Wilmington, Delaware. 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 . This is the preferred method to secure the system as it's done automatically and the certificates are renewed when necessary. communications. Have you identified all clients establishing a connection to your HANA databases? To learn more about this step, see SAP Host Agent must be able to write to the operations.d Linux' predictable network device names aka default network was "eth0" is now still predictably used as "enp1s0" with different rule set. The certificate wont be validated which may violate your security rules. For each server you can add an own IP label to be flexible. Above configurations are only required when you have internal networks. The XSA can be offline, but will be restarted (thanks for the hint Dennis).
