Copy on write data storage

In a networked computer system, data is stored in streams. When a request is received to modify a stream, the system checks to see whether the stream is frozen. If so, the system makes a copy of the stream and modifies the copy. If the frozen stream is stored locally, the copy may be stored remotely. The frozen stream may be compressed. The compression may replace a data element in the stream with a reference to one in a different stream that contains the same information. A file system may be defined in which the files are made up of one or more streams. The file system may be synchronized with one on the network. Streams may be frozen when they have not been accessed for a certain period of time. The system may be able to return the copy of the stream or the frozen version of the stream.

Versioned And Hierarchical Data Structures And Distributed Transactions

Presented herein are methods of replicating versioned and hierarchical data structures, as well as data structures representing complex transactions. Due to interdependencies between data entities and a lack of guaranteed message ordering, simple replication methods employed for simple data types cannot be used. Operations on data structures exhibit dependencies between the messages making up the operations. This strategy can be extended to various types of complex transactions by considering certain messages to depend on other messages or on the existence of other entries at the data store. Regardless of origin, these dependencies can be enforced by suspending the processing of messages with unsatisfied dependencies until all of its dependencies have been met. Alternately, transactions can be committed immediately, creating entities that include versioned identifiers for each of their dependencies. These entities can then be garbage collected of the parent objects are not subsequently created.

The method may also include calculating a content-based identifier to the object; creating another entry for the object in the replicated index, the other entry being keyed by the content-based identifier; and updating the replicated index to point from the unique temporary identifier to the content-based identifier.

Run-Time Engine Implemented on a Computing Device Allowing Synchronization of Records During Application Execution

A first database implemented on a remote device such as a handheld computer may be reconciled with a corresponding second database implemented on a host computer during execution of an application program on the handheld device. In addition, the application program may be executed according to program instructions stored in an application program file located in the remote device. The databases may be reconciled by first commencing execution of the application program. Then, during the course of program execution, a synchronization instruction located in said application program file is retrieved. The synchronization instruction is executed by establishing a communications link between the handheld computer and the host computer. Subsequently, any difference between the first database and the second database are reconciled. Furthermore embodiments of the invention contemplate that in addition to reconciling all of the databases located on the handheld and host computers, less than all of the databases may be reconciled to reduce the amount of time required to execute the reconciliation process. In addition, after reconciliation control may be returned to the calling application program, or to another application, as determined by the application designer.

Method for providing assistance in making change decisions in a configurable managed environment

In a configurable managed system having an associated configuration management database (CMDB), a Change Manager makes changes affecting configuration items (CIs), wherein different types of changes require different levels of confidence in the integrity of data in the CMDB. In response to a proposed change, weights assigned to system CIs affected by the change are used to compute a confidence level regarding accuracy of CMDB data pertinent to the change. The weight for a given CI is derived from the most recent synchronization thereof, and the numbers of reads, writes, and relationships the given CI has with other CIs. The confidence level is then used by the Change Manager in deciding whether or not to make the change. The proposed change is then allowed if the confidence level is no less than a pre-specified minimum value.

Parallel database backup and restore

Embodiments are directed to simultaneously backing up data from multiple locations to a single location and to restoring data from a single location to multiple locations simultaneously. In an embodiment, a computer system receives a backup command from a user which indicates that various specified portions of data are to be backed up. The data portions are stored in multiple different locations in a parallel database. The computer system generates multiple backup commands specific for each location in which the data is stored. The backup commands initiate a parallel backup from the various locations to a single location in a data store. The computer system also executes the generated backup commands in parallel, so that the data from each of the different locations is backed up in the data store.

Embodiments of the present invention provide an approach for providing non-disruptive transitioning of application replication configurations and proactive analysis of possible error scenarios. Specifically, under embodiments of the present invention, a common integration model (CIM)-compatible representation of a system replication plan is provided in a computer data structure. Based on the representation, a hierarchical tree data structure having a set of nodes is created. A set of system configuration updates pertaining to the set of nodes are then classified (e.g., based upon the type of configuration update). Once the set of nodes has been classified, the set of nodes may then be analyzed to determine if any nodes of the set are isomorphic. If so, the plan can be modified accordingly. In any event, the replication plan (or modified replication plan) may then be implemented.
