Abstract
A system, a method, and computer program product is disclosed for time sharing access control to data in a database system and executing a plurality of database processes to avoid contention of the database processes. A data table having a plurality of data groups or partitions is defined via a database management system, and is stored in a computer memory. A plurality of database process/time segments pairs are defined by pairing each of a plurality of database processes with each of a plurality of time segments. The defined pairs are stored in a computer memory. Each of the pairs is associated with at least one of a plurality of data groups or partitions of the data table, and the associations are stored in a computer memory. A request is received by the database management system that one of the database processes be given to access the data table. A time segment for the database process is determined via a computer processor. A database process/time segment pair for the database process is determined by using the determined time segment of the database process. The data group or partition of the data table with which the database process/time segment pair has been associated is…
