Patent number: 9223583Abstract: The present invention relates to methods and systems for method of implementing proactive token renewal and management in secure conversations. The method includes transmitting an secure conversation token (SCT) bootstrap request, receiving a first SCT in response to the SCT bootstrap request, and determining a round trip time (RTT) of the SCT bootstrap request. The method further includes determining the expiration time of the first SCT, based on the combination of the RTT and the expiration of the first SCT, scheduling an SCT renew request, and initiating the SCT renew request. Further, the method includes receiving a second SCT in response to the SCT renew request, receiving an indication that the first SCT has expired, and in response to the indicating, utilizing the second SCT.Type: GrantFiled: July 25, 2011Date of Patent: December 29, 2015Assignee: ORACLE INTERNATIONAL CORPORATIONInventors: Symon Szu-yuan Chang, Adam Lee, Thorick Chow, Alan Mullendore

Patent number: 8631238Abstract: The present invention relates to methods and systems for preventing race conditions in secure token conversations. The method includes generating a message from a client application to a server application, determining that a first secure conversation token (SCT) exists, and using the first SCT to encrypt the message. The method further includes sending the encrypted message to the server, receiving an indication that the first SCT has expired, and initiating an SCT renew request. The method includes storing the first SCT, receiving a second SCT in response to the SCT renew request, and storing the second SCT in addition to the first SCT. The method further includes retrieving an encrypted message, determining that the encrypted message has been encrypted using the first SCT, in response to the determination, using the first SCT to decrypt the message, and generating a response from the server to the client.Type: GrantFiled: July 25, 2011Date of Patent: January 14, 2014Assignee: Oracle International CorporationInventors: Symon Szu-yuan Chang, Adam Lee, Thorick Chow, Alan Mullendore

Patent number: 7962902Abstract: A system and method for accessing requested data in a database using result set objects. The invention also provides a set of enhancements to the EJB Query Language (“EJB QL”) for providing result sets using EJB QL and to efficiently access databases using select methods within Enterprise Java Beans. EJBQL language extensions allow for the selection and retrieval of result sets. Since the use of the invention is expressed in terms of object relational constructs defined in an EJB deployment, it allows for the retrieval of data from a database expressed in terms of the relationships defined in that EJB deployment.Type: GrantFiled: November 1, 2006Date of Patent: June 14, 2011Assignee: Oracle International CorporationInventors: Thorick Chow, Seth White

Patent number: 7774780Abstract: The feature of automatic retry of container-managed transactions configures the container to allow automatic retries of container-managed transactions that have been rolled back due to exceptions thrown at runtime. More specifically, on a per method basis, the container can be instructed to retry a failed transaction as using a new one up to a specified number of times if that method was the originator of the transaction that has been rolled back. The enabling of automatic transaction retries is accomplished either at deployment time by setting properties in the deployment descriptor of an instance of a class, such as EJB, or at runtime by setting properties on the EJB via a console on the application server. The automatic retry of container-managed transactions is a convenient feature that may alleviate the client of the task of explicitly coding transaction retries. In addition to programming convenience, retrying transactions using this feature may also offer performance benefits.Type: GrantFiled: October 15, 2004Date of Patent: August 10, 2010Assignee: BEA Systems, Inc.Inventors: Thorick Chow, Seth White

Patent number: 7756910Abstract: Users and processes are provided with various features to control the memory usage by a cache and pool dynamically at runtime. The cache and pool can be initialized on demand to remove idle objects of classes from them without the server being restarted. When the cache and pool reach their maximum sizes, idle objects in them may be removed to make room for newly active objects using various strategies in batches, where the schedule (periodicity), size and processing time of each batch can be dynamically adjusted. When a newly created object is being added to a full cache where each object is enrolled in a transaction, one or more active objects may be passivated from the cache based on various criteria to make room for the new instance to be added. Various features of the cache and pool can be defined in a configuration file.Type: GrantFiled: October 15, 2004Date of Patent: July 13, 2010Assignee: BEA Systems, Inc.Inventors: Thorick Chow, Seth White
