Oracle Error ORA-06131: NETTCP: user access denied

Oracle Error Message

ORA-06131: NETTCP: user access denied

Reason for the Error

The host’s SQL*Net TCP/IP server rejected this connection request because the client user(name) does not have access privilege – as determined by the contents of the Username Mapping Table (UMT), a component of the host’s CONFIG.ORA.

Solution

To grant access, add appropriate entry to the host’s UMT.
