Abstract: Disclosed are methods and apparatuses to provide a redo repeater that allows for no data loss protection without the performance impact to the primary database even when a significant geographical distance separates the primary and standby databases. The Repeater is a lightweight entity that receives redo from the primary database with the purpose of redistributing that redo throughout the primary/standby system configuration. The Repeater able to extend no data loss protection and switchover functionality to terminal standby databases even though the primary database does not need to have a direct connection with those destinations.

Abstract: Embodiments include systems and methods for optimization of micro-benchmark analysis for microprocessor designs. For example, embodiments seek to generate a suite of micro-benchmarks and associated weighting factors, which can be used to effectively define a weighted aggregate workload condition for a fine-grained (e.g., RTL) simulation in a manner that is a sufficient proxy for predicted commercial workload conditions. The suite of micro-benchmarks can be appreciably more efficient to simulate than the commercial workload, so that using the suite of micro-benchmarks as a proxy for the commercial workload can provide many benefits, including more efficient iterative design.

Abstract: Implementations described and claimed herein provide systems and methods for migration data from a source to a target in the background using an optimal number of threads. In one implementation, a directory entry in a source file system is compared to a size threshold. An optimal number of threads for a migration associated with the directory entry is allocated. The optimal number of threads is determined based on a degree of parallelism available for the migration and the comparison of the directory entry to the size threshold. The directory entry is migrated from the source file system to a target file system using the optimal number of threads.

Abstract: Techniques are herein described for creating a scalable IMAP4 compliant email system using a NoSQL database and a distributed full text search engine. Data for each email message is stored in multiple tables to avoid storing redundant data unnecessarily. However, a full text search index is created based on a single table as if the index refers to a single table. In embodiments herein described, the single index is created on the fields of a message metadata table with virtual fields added to the table that are derived from the message content. During this process, data is pulled from a message table in “blob” format and broken down into corresponding fields and data items, so the data items may be converted and placed in the proper virtual fields for index creation. Each blob section that is converted is cached, so the same blob section does not need to be converted multiple times. After index creation, the index may be used to search for emails based on metadata and data within the body of the email.

Abstract: A method for determining parameters for one or more air-cooling mechanisms for a computer system. A current operating temperature of a system component within a particular system is determined. A maximum operating temperature of the system component is obtained. A difference value between the maximum operating temperature and the current operating temperature is computed. A parameter of an air-cooling mechanism of an environment, which includes the system component, is selected and modified based on the difference value between the maximum operating temperature and the current operating temperature.

Abstract: A process for producing acetic acid is disclosed in which the methyl iodide concentration is maintained in the vapor product stream formed in a flashing step. The methyl iodide concentration in the vapor product stream ranges from 24 to less than 36 wt. % methyl iodide, based on the weight of the vapor product stream. In addition, the acetaldehyde concentration is maintained within the range from 0.005 to 1 wt. % in the vapor product stream. The vapor product stream is distilled in a first column to obtain an acetic acid product stream comprising acetic acid and up to 300 wppm hydrogen iodide and/or from 0.1 to 6 wt. % methyl iodide and an overhead stream comprising methyl iodide, water and methyl acetate.

Abstract: Embodiments of the present invention allow a system to use data gathered from social networks and other systems to determine an ordered list of desired topics or skills to define a subject matter area and incorporate the order of the topics or skills into a search. To define this subject matter area, embodiments can consider not just the topics or skills that are listed, but those topics or skills that are similar based on a pre-computed topic graph. These considerations can be incorporated into a generated query, so that the query itself accounts for similarity of topics via the topic graph and the order of desired terms. The query generation process can include a claimed skills veracity model that provides differential weighting to claimed skills, based on the skill-sets of users who are deemed to be similar to the user being evaluated.

Abstract: Access to a module element within a first module by a second module is prohibited if the module element within the first module has not been exposed to the second module. If a particular module element within a first module has been exposed to a second module, then access to the particular module element by the second module may or may not be allowed depending on: (a) whether the particular module element has been declared with a public or non-public access modifier, (b) whether a second exposed module element, which includes the particular module element, has been declared with a public or non-public access modifier, (c) a level of access associated with the operation that attempts to access the particular module element of the first module, and/or (d) whether an accessibility override configuration is set for accessing the particular module element.

Abstract: Techniques for efficient cursor sharing to enforce fine-grained access control are provided. In one technique, the authorization context of a database statement is stored in (or in association with) a corresponding cursor. The authorization context indicates multiple authorization results, each of which indicates whether a user (or role) associated with the database statement is allowed to access a different data set of multiple data sets that the database statement targets. An authorization context of an incoming database statement may be compared to the authorization context of a cursor in a single comparison to determine whether the authorization contexts match. If so, then the cursor may be shared. In another technique, one or more normalizations are applied to a cursor predicate that is generated based on the authorization context of a database statement. The one or more normalizations may result in removing one or more predicates from the cursor predicate.
