This is a combination method and system for intravascularly accessing and visualizing a body structure. A system is disclosed comprising a sheath, a balloon catheter, and a catheter deflection mechanism. A micro-deflection mechanism, which may be placed into the lumen of devices such as cardiac leads or electrophysiology catheters, is also provided for accurate guidance and placement of such devices to their target location. In one embodiment, a procedure for a lead or catheter placement is described in which a combination deflection mechanism, balloon catheter, and sheath assembly access the coronary sinus ostium via a superior approach. A distal balloon on the catheter is inflated and an occlusive venogram is obtained under fluoroscopic guidance to visualize the coronary veins. The sheath is advanced into the coronary sinus ostium and the balloon is deflated. The catheter and deflection mechanism are then removed.

A cache server is provided in a network for storing Java objects for retrieval by one or multiple application servers. Application server(s) are configured to request an object from the cache server, rather than requesting the Java object directly from a database, so as to reduce processing load on the database and free up database resources. Responsive to a request for a Java object from an application server, e. g. , in an HTTP request, the cache server determines if the object is stored in memory and if so, serializes the requested object and sends the serialized object to the requesting server, e. g. , in an HTTP response. The requesting server then deserializes the Java object. If the object is not stored in memory, the cache server instantiates the object (typically by requesting the object from the database), serializes the instantiated object and sends it to the requesting server. Cache coherency methods are also provided.

One embodiment of the present invention provides an enterprise system that automatically executes a rule associated with an event. During operation, the system receives an event object at the enterprise system. Next, the system creates an intermediate event object based on the event object, wherein the intermediate object is an invocation context for the rule. The system also filters a set of rules with the intermediate event object to obtain a subset of rules. The system then selects a rule that is associated with the event from the subset of rules. Finally, the system executes the rule.

Apparatus, methods, and computer program products are disclosed that determine Rights to an entity. The disclosed technology maintains data structures representing a set of entities. These entities include protected-entities and sensitivity-entities. Each of the sensitivity-entities is associated with a respective sensitivity access-control-list. The sensitivity-entities include a first sensitivity-entity that is associated with a first sensitivity-access-control-list. A first protected-entity being one of one or more of the protected-entities associated with the first sensitivity-entity. The technology evaluates Rights to the first protected-entity with respect to the first sensitivity-access-control-list and enables access to the first protected-entity responsive to the Rights evaluation and presents the first protected-entity when access is enabled.

Network security is enhanced in a multi-tenant database network environment using a query plan detection module to continually poll the database system to locate and raise an alert for suspect query plans. Security also can be enhanced using a firewall system sitting between the application servers and the client systems that records user and organization information for each client request received, compares this with information included in a response from an application server, and verifies that the response is being sent to the appropriate user. Security also can be enhanced using a client-side firewall system with logic executing on the client system that verifies whether a response from an application server is being sent to the appropriate user system by comparing user and organization id information stored at the client with similar information in the response.

Apparatus, methods, and computer program products are disclosed that maintain an association graph made up of association tuples. Each of the association tuples belongs to an access-control-policy scope that imposes an access control policy. On receipt of a client reference and a supplier reference a scope-defining entity is identified from the client reference. The scope-defining entity has an explicit access control policy. An effective supplier reference is retrieved from a set of the association tuples matching the scope-defining entity and is presented.

Embodiments of the invention provide systems and methods for a collaboration environment in which a number of different workspaces can use the same, reusable content. According to one embodiment, a method of providing collaboration using reusable content can comprise identifying a content item to be included in a first workspace of a plurality of workspaces of a collaboration environment. A first proxy representing the identified content item can be created. The first proxy can have a unique identifier within the first workspace. A mapping table record can be created for the first proxy that links the first proxy to the content item. Additionally, a cross-reference table record can be created for the first proxy. The cross-reference record can identify a relationship of the first proxy to another content item in the first workspace.
