Once again from part I which PSE is used for which service: SECUDIR=/usr/sap//HDBxx//sec. 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 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?? 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. least SAP HANA1.0 Revision 81 or higher. (check SAP note 2834711). Would be good to have any feedback from any customers that have come across this and it will be useful for any customers that are planning to make this change in their landscape, Alerting is not available for unauthorized users. Removes system replication configuration. Figure 10: Network interfaces attached to SAP HANA nodes. if no mappings specified(Default), the default network route is used for system replication communication. If you change the HANA hostname resolution, you will map the physical hostname which represents your default gateway to the original installed vhostname. The parameter listeninterface=.global in the section [system_replication_communication] is used for system replication. Using HANA studio. Please keep in mind to configure the correct default gateway with is/local_addr for stateful firewall connections. The last step is the activation of the System Monitoring. You can configure additional network interfaces and security groups to further isolate On existing HANA DB host we already have two file systems for DATA and LOG: On Dynamic Tiering Host the following file systems are required which will store ES data and logs: So after the above setup the actual architecture will appear as follows: Communication channel and network requirements. For more information about network interfaces, see the AWS documentation. There is already a blog post in place covering this topic. Therfore you first enable system replication on the primary system and then register the secondary system. 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 system, there are 2 configurable parameters. These are called EBS-optimized If you answer one of the questions negative you should wait for the second part of this series , ########### global.ini -> [internal_hostname_resolution] : 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. A full sync was triggered to TIER2 and after the completion the TIER3 full sync was triggered 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. Stay healthy, Started the full sync to TIER2 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. Thanks DongKyun for sharing this through this nice post.
