3461093 - Using SAP HANA Persistent Memory is only working with the primary system replication site and not the secondary, when the operation mode is delta_shipping

By checking with the Linux command df |grep hana it is detected that the tmpfs directories are not filled on the secondary replication server while the primary site's tmpfs directories are filled.

Secondary site:

Checking the system replication state of the secondary site shows that the operation mode is delta_datashipping
