SecurityLevel2::Credentials::invocation_options_required
Synopsis
Specifies the minimum number of security options to be used when establishing an SSL connection to make an invocation on a target object in the BEA Tuxedo domain.
OMG IDL Definition
attribute Security::AssociationOptions
invocation_options_required;
Argument
None.
Description
Use this method to specify that communication between principals and the BEA Tuxedo domain should be protected. After using this method, a Credentials object makes an invocation on a target object using the SSL protocol with the defined level of security options. This method should be used in conjunction with the SecurityLevel2::Credentials::invocation_options_supported method.
The following security options can be specified:
Return Values The list of defined security options. If the Tobj::TuxedoSecurity security mechanism is used to create the security association, only the NoProtection, EstablishTrustInClient, and SimpleDelegation security options are returned. The EstablishTrustInClient security option appears only if the security level of the CORBA application is defined to require passwords to access the BEA Tuxedo domain. Note: A CORBA::NO_PERMISSION exception is returned if the security options specified are not supported by the security mechanism defined for the CORBA application. This exception can also occur if the security options specified have more capabilities than the security options specified by the SecurityLevel2::Credentials::invocation_options_supported method.
The invocation_options_required attribute has set() and get() methods. You cannot use the set() method when using the Tobj::TuxedoSecurity security mechanism to get a Credentials object. If you do use the set() method with the Tobj::TuxedoSecurity security mechanism, a CORBA::NO_PERMISSION exception is returned.
