Hi Uneeb,

Hi

Apply recommendation from note 186119 - Restricting DB access to specific hosts

and set parameters

tcp.validnode_checking= yes

tcp.invited_nodes = (IP Adress1, IP Adress2, ...)

in the listener configuration file ($ORACLE_HOME/network/admin/protocol.ora)

There are to my knowledge no SAP recommendation that forbids changing the listener default port.
