ORA-01045: user GUEST lacks CREATE SESSION privilege; logon


The Oracle user lacks the CONNECT role.

Note: the CONNECT role consists of several privileges, one of which is CREATE SESSION.

Solution or Workaround

Grant the CONNECT role to the Oracle user. For example, the sdelayer command (above) will run successfully after the Oracle user named 'guest' is granted the CONNECT role.
