HANA System Replication is one of the important topic in SAP HANA. Being used in the context of high availability and disaster recovery scenario, It is really important to learn how to setup HANA System Replication in multi-tier replication scenario. In this scenario we are enabling HANA System Replication – In Multi-tier scenario. …
Here i am explaining different replication Modes between Sites in the HANA Replication setup. Synchronous (SYNC) : The secondary system sends an acknowledgment back to the primary system as soon as the data is received and persisted to the log volumes on disk. Asynchronous (ASYNC): Asynchronous replication, the primary does not wait until the secondary sends…
Parameter : statement_memory_limit Key Highlights : statement_memory_limit parameter is used to control memory limit for single query execution. Sometime it happens if we don’t set any limit on query level then single execution of query takes complete HANA memory and result to the HANA crash . So it is really improvement to set proper value…
Parameter : allocationlimit Key Highlights : This parameter is very useful in the Multi-tenant database container (MDC) system to set memory limit on each tenant system. Example : If we have 4 tenant systems in the landscape then we can set on indexsever.ini file –> allocationlimit for each tenant system to the accepted memory limit for each tenant…
Parameter: interval Description: Sets a time interval in seconds between two checks for differences of ini file parameters between primary and secondary systems in a system replication scenario. To disable/enable those checks, set the parameter [inifile_checker] enable. Value: Positive integer Default: 3600 (seconds = 1 hour) Restart required: No Ref:…
Key Highlights: This parameter will help in the scenario where we don’t want to replicate few parameter from primary to secondary site. Scenario where we want to have different value of particular parameters in primary and secondary site. This parameter is helpful where replication on the primary site with [inifile_checker]/replicate = true is enables With parameter…
inifile_checker –> enable = True & [inifile_checker]/replicate = true Key Highlights : [inifile_checker]/replicate = true- This parameter is very useful in the scenario where we have muli -tier and multi-target replication setup in the landscape . If we are changing any parameter in the primary site and [inifile_checker]/replicate = true- parameter is enabled then automatically it will…
