A process control method for a database includes storing identification information of an updating processing in a first storage region in association with update data when executing the updating processing for updating data stored in the first storage region of the database to the update data, and storing the identification information and a confirmation time in association with each other in a second storage region that is different from the first storage region in response to a confirmation processing of the updating processing.

A non-transitory computer-readable recording medium stores an encoding program that causes a computer to execute a process. The process includes first encoding a first character string in input data to a first code, when the first character string being registered in a first dictionary, the first code being associated with the first character string in the first dictionary; second encoding a second character string in input data to a second code and registering the second character string to a dynamic dictionary, when the second character string being not registered in the first dictionary, the second code being associated with the second character string and preliminary information in the dynamic dictionary; and generating encoded data including the encoded input data and the dynamic dictionary.
摘要:
An encoding device searches input text data for a date-time notation string that represents at least a date or time. The encoding device generates, upon finding the date-time notation string by the search unit, a converted date and time code including an identification code for identifying the date-time notation string and a normalized date and time notation formed by converting the date-time notation string into a specific date-time notation format. The encoding device converts the input text data based on conversion information that associates the converted date-time code generated by the generation unit with the date-time notation string.

When measuring a one-way packet transfer delay between first and second measurement devices in a time-asynchronous manner, the first measurement device transmits first packets each containing a first counter value at a time of transmission; and then transmits a second packet containing a second counter value at the time of the transmission. The second measurement device stores the first counter value extracted from each of the first packets, a third counter value at a time of reception, and reception time stamp information; calculates an incremental ratio between the first counter value and the third counter value per unit time; and calculates an expected fourth counter value at the time of the reception based on the second counter value and the incremental ratio, and obtains the transfer delay based on the calculated expected fourth counter value and an actual fourth counter value at the time of the reception.
摘要:
An information processing apparatus according to an embodiment determines whether a target character string is registered in a first dictionary, the target character string being a compression target contained in input data, outputs a compression code corresponding to the target character string when the target string is registered in the first dictionary, searches the target character string in first data when the target character string is not registered in the first dictionary, the first date accumulating character strings that are a part of the input data and have been determined to be not registered in the first dictionary, registers a matched character string in a second dictionary different from the first dictionary when the target character string is searched in the first data and outputs a compression code corresponding to a registration number of the target character string in the second dictionary.
摘要:
A data management apparatus includes a memory being accessible at a higher rate than a storage device, and a processor configured to control the memory to store a part of data stored in the storage device into a first storage area of the memory, the part of the data is cyclically selected from the data, and respond to a data request by using the cyclically selected part of the data stored in the first storage area.
摘要:
An information processing apparatus includes a processor configured to divide a first file of a first plurality of files stored in a storage device into a second plurality of files, each of the second plurality of files including a different range of values, when each range of values corresponding to each of the first plurality of files includes a specific range and a total size of the first plurality of files exceeds a threshold.
