Your rserve address needs to be your actual RServer address and Port via which you are accessing it.
host1:port1 wont work. Give actual values like for example - 10.10.10.1:8000
Also the parameters have _ between words:
cer_timeout
cer_rserve_addresses
cer_rserve_maxsendsize
Also change the timeout parameter to 3000. With the volume of data that you have 300 wont be enough.
Do the same for XS Engine in case you decide to call this from XSJS.
Restart your HANA instance and XS Engine after this.
