Abstract: A method include receiving input indicating a listener object and an interface for an object class corresponding to a persisted object of an object model retained by a database, where the interface has multiple different implementations within the object model; recording information indicating that the listener object has an interest in persistent data associated with the interface for the object class corresponding to the persisted object; in connection with a transaction with the database and when each of multiple Dirty( ) calls is received for the database, checking whether the interface for the object class corresponding to the persisted object is associated with the Dirty( ) call; and communicating with the listener object when the interface for the object class corresponding to the persisted object was associated with at least one of the Dirty( ) calls during the transaction.

Abstract: An apparatus, system, and method are disclosed for accessing a database. A request attribute module constructs a request attribute list from an attribute database for a data value name received in a request block, wherein the request block is an inquiry to a target database and is not formatted as a query statement for the target database. The request attribute list associates the data value name with an attribute name and a schema name. A schema name module adds the schema name from the request attribute list to a schema names list in response to the schema name not being included in the schema names list. An attribute name module adds the attribute name from the request attribute list to an attribute names list in response to the attribute name not being included in the attribute names list. A query module builds a query statement directed to the target database from the schema names list and the attribute names list.

Abstract: Described is a method for migrating versioned data from a source configuration management system to a target configuration management system. The method includes determining, for at least one historical period having versioned data items to be migrated from the source to target systems, an earliest versioned data item based on a start time for the historical period. At least one subsequent versioned data item is determined based on a sampling interval and an end time for the historical period. The earliest versioned data item and subsequent versioned data items for each historical period are migrated from the source configuration management system to the target configuration management system. Advantageously, migration is performed faster than if all existing versions are migrated and storage requirements are reduced. In addition, differencing tools in the target system can compare different versions of the migrated data items.

Abstract: A server apparatus performs data I/O processing on a P-VOL in response to a request from a client apparatus and includes a file system which receives data write and read requests in units of files from the client apparatus. The server apparatus stores, into a D-VOL, differential data generated by updating the P-VOL, and manages a snapshot management table wherein a block address of the D-VOL storing the acquired differential data is registered. When a remaining capacity of a storage area of the D-VOL becomes equal to or less than a predetermined threshold value, the server apparatus enables a block of the D-VOL which had stored therein the differential data on a certain predetermined file, to be used as a storage area for newly acquired differential data.

Abstract: A method of analyzing a string-pattern includes defining a minimum length (Lmin—1) of substrings (STR_A_B) to be considered; defining a maximum length (Lmax—1) of substrings (STR_A_B) to be considered; with a computer, searching the string-pattern for substrings (STR_A_B) with a length in an interval between the minimum length (Lmin—1) and the maximum length (Lmax—1); counting an occurrence (Occ_A_B) of each substring (STR_A_B) found with a length in the interval between the minimum length (Lmin—1) and the maximum length (Lmax—1); and pruning away a number of the substrings (STR_A_B) that meet one or more criteria. The criteria are selected from the group consisting of (1) being contained inside the maximum substring (STR_A_C) in a subset (SET_A) of substrings (STR_A_B), (2) being shorter than the maximum substring (STR_A_C), (3) occurring with a same frequency as the maximum substring (STR_A_C), and combinations thereof.

Abstract: A method, computer program product and data processing system for optimistic locking. An integer column is added to a database table. A Structured Query Language statement is constructed and prepared to form a prepared Structured Query Language statement, wherein a result set of the prepared Structured Query Language statement includes the integer column. Any required parameter information is set in the prepared Structured Query Language statement. The prepared Structured Query Language statement is executed in a database transaction. A unique key associated with an element of the result set of the prepared Structured Query Language statement is determined. The row of the database table that the unique key is associated with is determined. A value in the integer column of the determined row is determined. The value in the integer column of the determined row is stored to form a stored value associated with the unique key, wherein the stored value ceases to exist when the database transaction ends.
