Abstract: Methods and systems for efficient file replication are provided. In some embodiments, one or more coarse signatures for blocks in a base file are compared with those coarse signatures for blocks of a revised file, until a match is found. A fine signature is then generated for the matching block, of the revised file and compared to a fine signature of the base file. Thus, fine signatures are not computed unless a coarse signature match has been found, thereby minimizing unneeded time-consuming fine signature calculations. Methods are also provided for determining whether to initiate a delta file generation algorithm, or whether to utilize a more efficient replication method, based upon system and/or file parameters. In accordance with additional embodiments, the lengths of valid data on physical blocks are obtained from physical block mappings for the files, and these lengths and mappings are utilized for delta file generation, to minimize unnecessary signature computations.

Abstract: Techniques are described for upgrading systems that include a first set of agents for collecting target data from a plurality of targets and sending the target data to a first management server. In an embodiment, a second set of agents is pre-deployed. Each pre-deployed agent is configured to, upon activation, collect target data from a respective target of the plurality of targets and send the target data to a second management server. While the pre-deployed agent remains inactive, an agent from the first set of agents collects and sends the target data to the first management server. When a first batch of one or more pre-deployed agents is activated, each activated agent begins collecting target data and sending the target data to the second management server. For agents not in the first batch, the first set of agents continues to collect and send the target data.

In one embodiment, a method includes receiving a first new record for matching with other records. The method includes querying a database that stores respective single best records (SBR) for respective sets of matching records to return SBR information. The first new record is matched to the other records by comparing the first new record to the SBR information to identify an SBR that matches the first new record. The first new record is associated with the identified SBR in the database.

Abstract: The invention relates to a multiple QoS file system and methods of processing files at different QoS according to rules. The invention allocates multiple VLUNs at different qualities of service to the multiQoS file system. Using the rules, the file system chooses an initial QoS for a file when created. Thereafter, the file system moves files to different QoS using rules. Users of the file system see a single unified space of files, while administrators place files on storage with the new cost and performance according to attributes of the files. A multiQoS file system enhances the descriptive information for each file to contain the chosen QoS for the file.

Abstract: A two-level cache to facilitate resolving resource path expressions for a hierarchy of resources is described, which includes a system-wide shared cache and a session-level cache. The shared cache is organized as a hierarchy of hash tables that mirrors the structure of a repository hierarchy. A particular hash table in a shared cache includes information for the child resources of a particular resource. A database management system that manages a shared cache may control the amount of memory used by the cache by implementing a replacement policy for the cache based on one or more characteristics of the resources in the repository. The session-level cache is a single level cache in which information for target resources of resolved path expressions may be tracked. In the session-level cache, the resource information is associated with the entire path expression of the associated resource.

Abstract: Techniques for managing accounts are provided. An access management system may check out credentials for accessing target systems. For example a user may receive a password for a period of time or until checked back in. Access to the target system may be logged during this time. Upon the password being checked in, a security account may modify the password so that the user may not log back in without checking out a new password. Additionally, in some examples, password policies for the security account may be managed. As such, when a password policy changes, the security account password may be dynamically updated. Additionally, in some examples, hierarchical viewing perspectives may be determined and/or selected for visualizing one or more managed accounts. Further, accounts may be organized into groups based on roles, and grants for the accounts may be dynamically updated as changes occur or new accounts are managed.
