IBM General Parallel File System for AIX: Data Management API Guide

Required files for implementation of Data Management applications

The installation image for GPFS 1.3 or later, contains the required files for implementation of Data Management applications. See GPFS for AIX: Installation and Tuning Guide for further information regarding the installation of the General Parallel File System for AIX product.

dmapi.h

The header file that contains the C declarations of the DMAPI functions.

This header file must be included in the source files of the DM application.

The file is installed in directory: /usr/lpp/mmfs/include.

dmapi_types.h

The header file that contains the C declarations of the data types for the DMAPI functions and event messages.

The header file dmapi.h includes this header file.

The file is installed in directory: /usr/lpp/mmfs/include.

libdmapi.a

The library that contains the DMAPI functions.

The library libdmapi.a consists of a single shared object, which is built with auto-import of the system calls that are listed in the export file dmapi.exp.

The file is installed in directory: /usr/lpp/mmfs/lib.

dmapi.exp

The export file that contains the DMAPI system call names.

The file dmapi.exp needs to be explicitly used only if the DM application is to be explicitly built with static binding (using the binder options -bnso -bI:dmapi.exp).

The file is installed in directory: /usr/lpp/mmfs/lib.

dmapicalls

Module loaded during execution of the DMAPI functions.

The module is installed in directory: /usr/lpp/mmfs/bin
