DATA EXPANSE USING MEMORY-MAPPED FILES ON A SYSTEM ARCHITECTURE INTERFACE LAYER-BASED MAINFRAME OPERATING SYSTEM |
| 摘要 |
Systems and methods for obtaining access to database files in a computing system. A method may include receiving a first call from a database management system requesting access to a database file. The method may further include transmitting a second call to an operating system interface requesting that a memory-mapped data expanse file be created. The method may also include receiving a first address representing the database file in response to successful mapping of the database file to the memory-mapped data expanse file located at the operating system interface. |

1. A method for obtaining access to database files in a computing system, comprising:
receiving, at an operating system, a first call from a database management system requesting access to a database file; transmitting, from the operating system, a second call to an operating system interface requesting that a memory-mapped data expanse file be created; and receiving, at the operating system, a first address representing the database file in response to successful mapping of the database file to the memory-mapped data expanse file located at the operating system interface. |
