Can OLTP transactions happen on primary and secondary site simultaneously?

Lets say i have a db/system in region - a and sync that to region -b

Can users access both the systems simultaneously? I mean a user near to region -b access to ‘b’system and near region -a access to ‘a’ system and both systems can be in sync of respective transactions? Is this scenario possible with sap / sap hana ?

    Hello Raghu,

    Yes primary and secondary system both can be accessible for read operations.

    There is an Operation mode called logreplay_readaccess and it enables you to establish Active/Active scenario for hana system. DML operations are not allowed however on secondary site, that is restricted only for primary site.

    Best Regards,
