Abstract: An improved system and method is provided for adaptively refreshing a web page. A base version of the web page may be partitioned into a collection of fragments. Then the collection of fragments may be compared with the corresponding fragments of a recent version of the web page to determine a divergence measurement of the difference between the base version and the recent version of the web page. The divergence measurement may be recorded in a change profile representing a change history of the web page that includes a sequence of numeric pairs indicating a time offset and a divergence measurement of the difference between a version of the web page at the time offset and a base version of the web page. The refresh period for the web page may be adjusted by applying an adaptive refresh policy using the divergence measurements recorded in the change profile.

Abstract: Aspects of the subject matter described herein relate to versioning for databases. In aspects, two or more users may share the same version of data, such as a report, in a database. One of the users may seek to update the data. In response to a request from the user, a new version of the data is created. For data that is not updated via the request, the new version shares data with the previous version, thus saving space. For data this is updated, new segments within the database are created to store the updated data. Each user is allowed to access the data without blocking other users accessing the data.

Abstract: A Java-based application server, which supports multiple component models, includes a classloading module to enforce dependencies among classes and among the components that uses the classes. The classloading module determines whether a classloader created at deployment can share a version of a class with other classloaders.

The classloading module uses pluggable classloading policies to determine the rules to be followed during classloading operations. The same state machine is used for classloading and for controlling the lifecycle of multiple component modules. The classloading module also utilizes abstraction of interfaces to communicate requirements and capabilities among the classloaders and with the system.

Abstract: A database enables versioning for objects stored in the database via a “snapshot” operation. In one implementation, a device performs a snapshot operation in which a snapshot object, representing a logical view of database objects at a time at which the snapshot operation is performed, is created and stored in the database.

Further, in response to the request to store the modified version of the database object, the modified version of the database object is inserted in the database when the previous version of the database object was last modified before the most recent snapshot operation.

Abstract: A technique for implementing fast path grace period detection for deferring the destruction of a shared data element until pre-existing references to the data element are removed. A check is made, without using locks to exclude other updaters, for the presence of readers that are accessing the shared data elements. Grace period detection is terminated to initiate deferred destruction of the data element if there are no readers accessing the shared data element. If there are readers accessing the shared data element, a lock is implemented and another check is made for the presence of the readers.

Abstract: A technique for improving the performance of RCU-based searches and updates to a shared data element group where readers must see consistent data with respect to the group as a whole. An updater creates one or more new group data elements and assigns each element a new generation number that is different than a global generation number associated with the data element group, allowing readers to track update versions. The updater links the new data elements into the data element group and then updates the global generation number so that referential integrity is maintained. This is done using a generation number element that is referenced by a header pointer for the data element group, and which in turn references or forms part of one of the data elements. After a grace period has elapsed, the any prior version of the generation number element may be freed.

Abstract: A method, system, computer program product, and related business methods for phased rollout of an upgraded version of a web-based business information system are described. URLs associated with client requests remain the same even where the target subscriber accounts have been upgraded. Client requests for both upgraded and non-upgraded accounts are received by a common set of web servers. Client requests representing external entry points are trapped, and the receiving web server accesses a login router database to determine whether the target subscriber account is upgraded or non-upgraded, and then transfers the request to an appropriately-versioned application server. Application server sets are mapped to database sets according to system version, allowing the upgraded system database schema to be substantially different than the non-upgraded database schema. An early adopter program business method leveraging the abilities of such web-based business information system is also described.

Abstract: Concurrent resizing and modification of a first RCU-protected hash table includes allocating a second RCU-protected hash table, populating it by linking each hash bucket of the second hash table to all hash buckets of the first hash table containing elements that hash to the second hash table bucket, and publishing the second hash table. If the modifying comprises insertion, a new element is inserted at the head of a corresponding bucket in the second hash table. If the modifying comprises deletion, then within an RCU read-side critical section: (1) all pointers in hash buckets of the first and second hash tables that reference the element being deleted are removed or redirected, and (2) the element is freed following a grace period that protects reader references to the deleted element. The first table is freed from memory after awaiting a grace period that protects reader references to the first hash table.
