Provided are techniques for using containers to store objects. One data store from a set of data stores is assigned as a primary data store, wherein the remaining data stores comprise secondary data stores. A container for a group is created on the primary data store. A unique identifier for the container is generated on the primary data store. Metadata for the container is stored on the primary data store. Zero or more objects are stored in the container on the primary data store. For each of the secondary data stores that have objects belonging to the group, a container is created in that secondary data store having the unique identifier, wherein the container spans the primary data store and the secondary data stores, and wherein the objects in the container do not span the primary data store and the secondary data stores.

Scalable, distributed containerization across homogenous and heterogeneous data stores

An electronic-discovery system and method, wherein content items and hold anchors are stored in a repository, tracking objects and representational anchor objects are stored in a database system, and the tracking objects represent the content items and the representational anchor objects represent the hold anchors. A first hold anchor is used for placing a hold on the content items for a first defined period of time, and a first representational anchor object and one or more of the tracking objects are used for representing and tracking the holds for the first defined period of time. When the first defined period of time expires, a second hold anchor is used for placing the hold on the content items for a second defined period of time, and a second representational anchor object and the tracking objects are used for representing and tracking the holds for the second defined period of time.

System and method to optimally apply local retention in a remote repository

According to one embodiment of the present invention, a system extends a content repository by creating an auxiliary data store outside of the content repository and storing auxiliary data in the auxiliary data store, wherein the auxiliary data is associated with a collection of documents in the content repository. The system stores version information for the auxiliary data store and records of operations against the auxiliary data store in a log in the repository. In response to receiving a request for an operation against the auxiliary data store, the system determines that the auxiliary data store and repository are consistent based on the version information and applies the operation against the auxiliary data store. Embodiments of the present invention further include a method and computer program product for extending a content repository data model in substantially the same manners described above.

Extending a content repository using an auxiliary data store

In searching electronic documents, prior to executing a query, a reviewer indicates whether a result set of the query will be dynamic or static. The query is then executed on the electronic documents to obtain an original result set, which is provided to the reviewer through a user interface. Upon determining that one or more changes to one or more of the electronic documents have occurred, and if the result set is static, then the original result set continues to be provided to the reviewer without re-executing the query. If the result set is dynamic, then the query is re-executed on the electronic documents to obtain an updated result set, and the updated result set is provided to the reviewer through the user interface. The original result set may be associated with a search session and/or may be a random sample of the electronic documents for an overview query.

Strategies for result set processing and presentation in search applications

A computer-based filtering method driven by a ruleset for positive and negative filtering with flexible comparison operations. Method first creates a ruleset as an ordered collection of rules which has a single ruleset default action. Each rule has a rule action, a comparison operation and at least one comparison data element. Filtering of an object from the ruleset result set is performed with the comparison operation on the object and the comparison data from the ruleset. Filtering step invokes each rule from the ruleset to compare the object with each comparison data element to determine whether or not the object is to be included or excluded from the result set. Filtering stops after the first matching rule is found and then the rule action is taken, or after invoking all rules without finding the matching rule and then the ruleset default action is taken.

Use of positive and negative filtering with flexible comparison operations

A method, system, and computer program product for managing results in a locale independent manner in a multi-node networked data processing system is provided. In one embodiment, a first node sends a command request to a second node. The command request contains a command and a locale in which the text of the result is desired. The first node receives the results of execution from the command request sent to and executed on the second node. The result generated by the second node in response to the command request includes one or more messages, wherein each message contains a unique message identifier, locale in which its associated text is stored, and text associated with the message. Responsive to a determination that the locale of the message text is in a locale different from a desired locale, the first node replaces the message text contained within the result with message text corresponding to the desired locale to produce a modified result and sends the modified result to the requesting client node.

Language independent message management for multi-node application systems

A chained bootstrap that is identified on a Boot Image Negotiation Layer (BINL) server and which is specified as the default bootstrap for the remote booting of client machines without regard to what client OS will finally be booted, is provided. The default bootstrap is downloaded as the initial bootstrap when the client sends the remote boot request to the TFTP boot server identified by the BINL server. This bootstrap then acquires a configuration file for the client from the TFTP server and determines the specific OS and associated bootstrap to download to the client. The chained bootstrap then relocates itself in memory on the client so that the actual client OS bootstrap can load and execute properly. The chained bootstrap then requests the actual client bootstrap from the TFTP server to continue the boot of the OS.

System for remote booting of muntliple operating systems using chained bootstrap mechanism in a network

A network is described including a server and a network device remotely coupled to the server. The network device includes a non-volatile storage device having data stored therein, which is preferably modified solely in response to instructions generated by the server. During initialization, the network device performs a first portion of an operating system boot sequence then generates and forwards trigger data, which includes identification information for identifying the network device, to the server. In response, the server generates action data, which includes one or more data update instructions for modifying the data stored within the non-volatile storage device. Following a second portion of the operating system boot sequence, the action data is forwarded from the server to the network device. If the action data includes one or more data update instructions, the network device performs the one or more data update instructions and repeats the operating system boot sequence.

System and method for server managed modification of operating system data stored within a network device

The present invention provides a system for creating server-managed configuration information for computing devices. The configuration information is composed of individual configuration components. The configuration components can be grouped for convenience into templates called machine classes, which can be used to manage a set of similar machines. Configuration components and machine classes can be stored permanently in a database. Machine classes are instantiated with machine-specific information such as network addresses and configuration information for peripherals to produce fully configured operating systems for a computing device. Software and configuration information is installed based on the machine class selected. Individual configuration components can be added or overridden when the machine instance is created. The machine instance can be customized with additional configuration information, such as its network address(es), machine name, and video resolution. The machine instance can be used either to boot a device remotely or to install the operating system locally on the computing device.

Server based configuration of network computers via machine classes

A pragma is defined to indicate straight path optimization for compilers (SPOC). The pragma is inserted into source code to identify the most common case for a branch point in a program flow, determined by analysis of performance data or simple prediction. The compiler employs this information to optimize the common case as a straight path through the function assembler code, removing unnecessary jumps and the nonoptimized case from the function body. The resulting executable code is more compact and executes faster.
