Abstract: Mailbox pooling pre-emptive criteria is set forth for use in an adaptive polling system for synchronizing data between a mail server and a mobile communication device. The polling engine stores an indication of the number of messages in the mailbox, the total mailbox size (i.e. the used storage size in bytes), and the last message ID from the last poll. In the next poll, the polling engine retrieves this information from the mailbox and checks against the values stored from the last poll. If the information is the same, then there is no need to compare the message ID list. Whenever either the number of messages in the mailbox or the mailbox size or last message ID has changed, then the full comparison of the message ID list is performed.

Abstract: A server is used to send data records to clients. A client #1 may synchronize with the server using a first path and a first protocol. The client #2 may synchronize with the server using a second path and a second protocol. In addition to synchronizing with the server, client #1 and client #2 may synchronize data records with each other using a third path and a third protocol. When synchronizing through different paths and/or protocols, data record identifiers may be generated differently. Thus, devices may not be able to synchronize data records if the data records are identified differently by client #1, client #2, and/or the server. A universal identity is used to allow for synchronization through three paths and protocols. Thus, client #1 and client #2 may synchronize data records through the third path and third protocol using the universal identity for data records.

Abstract: In a particular implementation, providing a virtual cached network drive, on a client, for PST-type (Personal STore) file operations, during a non-optimal connection. In one implementation, during the non-optimal connection, changes to objects, in a local PST file, are saved in a local cache (the virtual network drive) and logged. At certain intervals, the changes are compiled, compared with entries in a synchronization database and a list of changes, to be performed on the objects, is generated which is used to update a remote PST. If the connection remains non-optimal, a temporary PST file is created, based on the list of changes, and transferred to a remote agent that performs the changes on the remote PST. If the connection improves, the changes are instead performed directly on the remote PST.

If the data is stored remotely, the user credentials associated with the user's process space within which the application program is executing can be utilized to identify, and then provide, relevant authentication information to the remote data store, should it be required.

Abstract: An application server in a multi-tenant computing system is enabled access to a first set of tables and views in a database according to a first schema. The views in the first schema correspond to a table in a second schema. Thereafter, the table in the second schema is modified to add a column. Views of the modified table as defined by the second schema are generated in a third schema so that the third schema defines a second set of tables and views in the database. Subsequently, access by the application server to the second set of tables and views in the database is enabled and access by the application server to the first set of tables and views in the database is prevented. Related apparatus, systems, techniques and articles are also described.

Abstract: Various techniques for improving the performance of restoring deduplicated data files from a server to a client within a storage management system are disclosed. In one embodiment, a chunk index is maintained on the client that tracks the chunks remaining on the client for each data file that is stored to and restored from the storage server. When a specific file is selected for restore from the storage server to the client, the client determines if any local copies of this specific file's chunks are stored in files already existing on the client data store. The file is then reconstructed from a combination of these local copies of the file chunks and chunks retrieved from the storage server. Therefore, only chunks that are not stored or are inaccessible to the client are retrieved from the server, reducing server-side processing requirements and the bandwidth required for data restore operations.

Abstract: When a document in which a shortcut has been set is exchanged to another document, a shortcut to the document before the exchange is enabled to effectively act on the document after the exchange.

Abstract: Data is recursively migrated during uptime from a first table to a second table in a first schema in a database while taking into account changes to the first table in a change table. The database has first and second application servers respectively connecting to the database using first and second schemas and running first and second versions of a software program. Downtime can be initiated to migrate the remaining entries in the change table to the second table, delete the first table, and rename the second table to have a same name as the first table prior to deletion so that during uptime the second application server connects to the second table and runs the second version of the software program. Related apparatus, systems, techniques and articles are also described.

Abstract: A method and system is provided for reducing delay to applications connected to a database server that guarantees no data loss during failure or disaster. After storing a log record persistently in a local primary log, the log writer returns control to the application which continues running concurrently with the database server sending the session's log records to a standby database. A separate back channel is used by the standby to communicate, out-of-band to the primary, the location of the last log record stored persistently to the standby log. An application waiting for a transaction to commit may wait until the transaction's commit record has been persisted. Also described is a technique for reducing application delay when there is contention between nodes of a multi-node cluster for updating the same block. The technique provides for an asynchronous ping protocol that guarantees zero data loss during failure or disaster.
