InformationThe SEC_CASE_SENSITIVE_LOGON information determines whether or not case-sensitivity is required for passwords during login.
Note: This parameter has been deprecated in 12.1 and higher versions.
Oracle database password case-sensitivity increases the pool of characters that can be chosen for the passwords, making brute-force password attacks quite difficult.
SolutionTo remediate this setting, execute the following SQL statement.
ALTER SYSTEM SET SEC_CASE_SENSITIVE_LOGON = TRUE SCOPE = SPFILE;
