Description

Symptom

Oracle 11.2 initSID.ora/spfileSID.ora parameter REMOTE_OS_AUTHENT is not set to false.

Solution

  • Log in as user orasid or sidadm.
  • Start sqlplus as sysdba: sqlplus / as sysdba
  • Enter the following command to check the parameter: show parameter remote_os_authent
  • To change the parameter, execute: ALTER SYSTEM SET remote_os_authent=FALSE SCOPE=SPFILE;

Reason and prerequisites

When SAP Secure Store is used for an Oracle 11.2 database connection, the parameter remote_os_authent should be reset to false. For Oracle 12.1, the parameter is deprecated.
