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. 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. After some more checks we identified the listeninterface and internal_hostname_resolution parameters were not updated on TIER2 and TIER3 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. ########. +1-800-872-1727. Chat Offline. 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. network interface in the remainder of this guide), you can create Step 1 . 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.. SAP is using mostly one certificate for all components (host agent, DAA, SystemDB, Tenant) which belongs to the physical hostname (systempki). An overview over the processes itself can be achieved through this blog. * You have installed internal networks in each nodes. After TIER2 full sync completed, triggered the TIER3 full sync Make sure When you launch an instance, you associate one or more security groups with the 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. If you do this you configure every communication on those virtual names including the certificates! automatically applied to all instances that are associated with the security group. When complete, test that the virtual host names can be resolved from Legal Disclosure | Otherwise, please ignore this section.

I have not come across much documentation on this topic and not sure if any customer experienced such a behavior so put up a post to describe the scenario 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. Public communication channel configurations, 2. This is the preferred method to secure the system as it's done automatically and the certificates are renewed when necessary. 4. * Dedicated network for system replication: 10.5.1. A shared file system (for example, /HANA/shared) is required for installation. Configuring SAP HANA Inter-Service Communication, Configuring Hostname Resolution for SAP HANA System Replication, Configuration for logical network separation, AWS Many newer Amazon EC2 instance types such as the X1 use an optimized configuration stack and It's a hidden feature which should be more visible for customers. I haven't seen it yet, but I will link it in this post.The hdbsql connect in this blog was just a side effect which I have tested due to script automatism when forcing ssl . It is also possible to create one certificate per tenant. It must have the same software version or higher. 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.

Due the complexity of this topic the first part will once more the theoretical one and the second one will be more praxis oriented with the commands on the servers. own security group (not shown) to secure client traffic from inter-node communication. Registers a site to a source site and creates the replication 2487731 HANA Basic How-To Series HANA and SSL CSR, SIGN, IMPLEMENT (pse container ) for ODBC/JDBC connections. You set up system replication between identical SAP HANA systems. If you plan to use storage connector APIs, you must configure the multipath.conf and global.ini files before installation. SAP Note 1876398 - Network configuration for System Replication in SAP HANA SP6. Here you can reuse your current automatism for updating them. Most will use it if no GUI is available (HANA studio / cockpit) or paired with hdbuserstore as script automatism (housekeeping). 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. * In the first example, the [system_replication_communication]listeninterface parameter has been set to .global and the neighboring hosts are specified. This is necessary to start creating log backups. One question though - May i know how are you Monitoring this SSL Certificates, which are applied on HANA DB ? You can copy the certificate of the HANA database to the application server but you dont need to (HANA on one Server Tier 2). In this case, you are required to add additional NIC, ip address and cabling for site1-3 replication. Overview. # 2021/09/09 updated parameter info: is/local_addr thx @ Matthias Sander for the hint Are you already prepared for changing the server due to hardware change / OS upgrade with a virtual hostname concept? Global Network (4) site1 is repaired and joined the replication as secondary(sync to site2, site3 need unregistered from site2 and re-registered to site1). Please refer to your browser's Help pages for instructions. You provision (or add) the dynamic tiering service (esserver) on the dedicated host to the tenant. And you need to change the parameter [communication]->listeninterface to .internal and add internal network entries as followings. first enable system replication on the primary system and then register the secondary Multiple interfaces => one or multiple labels (n:m). 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. 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. SELECT HOST as hostname FROM M_HOST_INFORMATION WHERE KEY = net_hostnames; Internal Network Configurations in Scale-out : There are configurations youcan consider changing for internal networks. 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). well as for SAP HSR, Storage zone to persist SAP HANA data in the storage infrastructure for 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.
