Patent number: 9529694Abstract: Techniques for adaptive trace logging include, in one embodiment, obtaining input data on trace logging behavior and computing resources used by trace logging. Based on the obtained input data, an adaptive trace logging module automatically takes action at runtime to reduce the amount of computing resources consumed by tracing logging. For example, the action taken may include decreasing a trace logging level of an executing software program to reduce the number of trace logging messages added to a trace log. In another embodiment, the techniques include detecting a condition of an executing software program that warrants a change to a trace logging level of the executing program. The adaptive trace logging module automatically changes the trace logging level of the executing program as-needed for the detected condition. For example, the adaptive trace logging module may increase the trace logging level of an executing program upon detecting a deadlock or other abnormal condition of the executing program.Type: GrantFiled: September 14, 2009Date of Patent: December 27, 2016Assignee: ORACLE INTERNATIONAL CORPORATIONInventors: Deepti Srivastava, Wilson Chan, John Hsu, Eugene Ho, Tolga Yurek, Beverly Zane, Angelo Pruscino

Patent number: 9405694Abstract: Techniques are provided for using an intermediate cache between the shared cache of an application and the non-volatile storage of a storage system. The application may be any type of application that uses a storage system to persistently store data. The intermediate cache may be local to the machine upon which the application is executing, or may be implemented within the storage system. In one embodiment where the application is a database server, the database system includes both a DB server-side intermediate cache, and a storage-side intermediate cache. The caching policies used to populate the intermediate cache are intelligent, taking into account factors that may include which object an item belongs to, the item type of the item, a characteristic of the item, or the type of operation in which the item is involved.Type: GrantFiled: September 16, 2014Date of Patent: August 2, 2016Assignee: Oracle Internation CorporationInventors: Kiran Badrinarain Goyal, Neil J.

Patent number: 8103642Abstract: A method and apparatus for managing locks in a database system is provided. A master node grants a lock on a first resource and a group of resources that includes the first resource to a first requester node. The requester node receives a mapping corresponding to the group of resources that may indicate that a lock already exists for a second resource in the group. If the requester node desires a lock on a resource located in the group, the requester node grants itself the lock without notifying the master node. A second requester node requests a lock for a particular resource in the group of resources. The first requester node grants the lock on the particular resource and updates the mapping to indicate that a different node holds a lock for the particular resource.Type: GrantFiled: February 3, 2006Date of Patent: January 24, 2012Assignee: Oracle International CorporationInventors: Eugene Ho, Wilson Wai Shun Chan, Tak Fung Wang, Angelo Pruscino, Tolga Yurek

Patent number: 7921090Abstract: Methods and apparatuses for providing access to data in a cluster database are described. Embodiments of the invention include identifying situations in which many nodes require relatively equal access to a data block, and taking appropriate measures to improve the performance of the system in these situations. For example, a node may automatically downgrade its lock from an X lock to an S lock as soon as it has finished a modification of the data. S locks are sent to other nodes in the system as soon as a modification is complete. Modifications to the data are also sent to other nodes in the system as soon as a modification is complete. Depending on the size of the data modification, the entire data block may be sent, or only the modifications to the data may be sent.Type: GrantFiled: June 9, 2006Date of Patent: April 5, 2011Assignee: Oracle International CorporationInventors: Eugene Ho, Kotaro Ono, Neil Macnaughton, Michael Zoll, Herbert van den Bergh

Patent number: 7600063Abstract: Techniques are provided for performing changes to a resource governed by a locking mechanism. An entity (such as a server instance in a database system cluster) requests permission to modify the resource. In response to the request, the entity receives a first lock on the resource, which grants permission to perform the change to the resource without making the change permanent. After receiving the first lock, the entity performs the change to a copy of the resource that resides in shared memory without making another copy of the resource. After performing the change and until receiving permission to make the change permanent, the entity prevents the change to the resource from becoming permanent. After performing the change, the entity receives a second lock on the resource, which grants the entity permission to make the change permanent. After receiving the second lock, the entity ceases to prevent the change to the resource from becoming permanent.Type: GrantFiled: September 15, 2006Date of Patent: October 6, 2009Assignee: Oracle International CorporationInventors: Juan Loaiza, Neil MacNaughton, Eugene Ho, Vipin Gokhale, Kiran Goyal, Tirthankar Lahiri

Patent number: 7315910Abstract: Techniques are described herein for handling lock-related inconsistencies. As mentioned above, such inconsistencies occur when two or more sets of lock information, relating to the same resource, convey inconsistent information about locks requested and/or granted on that resource. In general, the techniques involve causing the locally-stored lock information about a resource to be sent to the master node of the resource. The master node of the resource compares the lock information thus received against the lock information maintained by the master node. Based on the comparison, the master node determines how to resolve the lock-related inconsistency, and sends messages to those nodes that need to change their local lock information for the resource. Once all of the lock information has been made consistent, the resource made available for access.Type: GrantFiled: June 16, 2005Date of Patent: January 1, 2008Assignee: Oracle International CorporationInventors: Wilson Wai Shun Chan, Angelo Pruscino, Stefan Roesch, Michael Zoll, Tolga Yurek, Eugene Ho

Publication number: 20070257693Abstract: An integrated circuit is described. The integrated circuit includes an interface circuit that includes a transmitter and a receiver. A generator in the integrated circuit is selectively coupled to the transmitter. The generator is to provide a test sequence that is output by the transmitter during a test mode of operation. A memory in the integrated circuit is selectively coupled to the generator and the receiver. The memory is to receive and synchronize the test sequence and a signal corresponding to the test sequence that is received by the receiver. A logic circuit in the integrated circuit is to compare the test sequence and the signal.Type: ApplicationFiled: May 3, 2006Publication date: November 8, 2007Inventors: Bret Stott, Philip Yeung, John Brooks, Benedict Lau, Chanh Tran, Eugene Ho
