mechanisms are provided to securely access systems of a distributed computer system by entering passwords. Some systems are accessible by equal, and some systems are accessible by different passwords. The mechanisms store information, which systems (I, II) are accessible by equal, and which are accessible by different passwords and ask to enter a proper password when opening a session by accessing a system of the distributed computer system. The mechanisms cache the password and use the stored information to verify, if another system to be accessed during the current session is accessible by an equal password like a system already accessed during said session. If the result of the verification is true, the mechanisms re-use the adequate cached password. If the result of the verification is false, the mechanism ask to enter a proper password to access the other system and cache the password required to access the other system in a way that during the current session, it can be re-used when accessing other systems accessible by the same password.

Secure access to a plurality of systems of a distributed computer system by entering passwords

The present invention provides a system and method for automatically managing IT-resources in a heterogeneous environment on each level of resource abstraction and resource hierarchy by using the concept of the resource-reference object. The resource-reference object represents the link to a referenced resource on a lower level in the hierarchy and may include a priority value assigned by the respective level of hierarchy as well as all information to build a remote request to that referenced resource which may be a single resource or a resource group. Concurrently each resource-reference object itself is accessible from the higher level of hierarchy as an own resource by additional providing a name and a desired state which can differ from desired state of the referenced resource as well as making it externally visible. Resource-reference objects can be grouped to resource groups on the higher level of hierarchy, wherein those resource groups are addressable as own resource-reference object from the next higher level of hierarchy. By using the inventive concept of the resource-reference object conflicts between different levels of hierarchies in the system management are resolved by a conflict resolution method using the priority assigned to the resource reference object by the respective level of hierarchy.

System and method for automatically managing IT-resources in a heterogeneous environment

A method for using WebServices as a basis for implementing an application programming interface (API) of a high-level programming language between a service application and a client application is disclosed. Function parameters of an API function call represent a complex object structure (COS). The method includes serializing the COS into serialized payload data, encoding the serialized payload data to form a payload string that does not contain any XML-specific characters, and specifying the parameters of the API call in parts of an input message of a corresponding operation in a WSDL document. The method also includes transporting the payload string within the input message to the service application, decoding the payload string to yield the serialized payload data, and deserializing the serialized payload data to restore the COS representing the parameters of the API call. A system and computer program product for implementing the API on the basis of Web Services are also disclosed.

A method, system and program product is provided for dynamically integrating Backend System instances into a J2EE application server environment during runtime without having to restart the J2EE application server environment. The system comprises a deployment descriptor for deploying a J2C Connector into the J2EE application server environment and a Join/Leave manager. The manager implements an interface for detecting the Backend System instances, and an interface for providing access data and status information about the Backend System instances to the application. In addition, at least one node is enabled to run an application or its subcomponent for adding access data to, and deleting it from a storage media.
