Information
As limiting the number of the SESSIONS_PER_USER can help prevent memory resource exhaustion by poorly formed requests or intentional Denial-of-Service attacks, this value should be set according to the needs of the organization.To enable this setting it is necessary to enable the RESOURCE_LIMIT ( ALTER SYSTEM SET RESOURCE_LIMIT = TRUE; ).
Solution
To remediate this setting execute the following SQL statement. ALTER PROFILE DEFAULT LIMIT SESSIONS_PER_USER 10;
