Ensure 'SQLNET.ALLOWED_LOGON_VERSION_SERVER' Is Set To 12a

AltaNivel 1Automatizadaoracle-db

Descripción

This setting SQLNET.ALLOWED_LOGON_VERSION_SERVER configures the minimum authentication protocols clients can use to connect to database instances. Please note that the term VERSION in the parameter name refers to the version of the authentication protocol, not the version of the Oracle Database release. The last uncommented setting in sqlnet.ora must equal 12A (case-insensitive, spaces ignored). Default: 12 Reads the file from $TNS_ADMIN, or $ORACLE_HOME/network/admin when TNS_ADMIN is unset (Linux/UNIX hosts); fails when neither directory exists.
