Universal Access Layer (UAL)

Introduction

The UAL (Universal Access Layer) is a multi-language library that allows exchanging Consistent Physical Objects (CPOs) between various modules, and to write to an ITM database. The documentation here is provided for rather experienced users who want to practice the UAL in their test programs. Regular KEPLER users do not need to know anything about the UAL. KEPLER manages transparently the UAL calls, which are embedded in the physics code wrappers. No UAL calls should be made inside physics modules.

Prior using the UAL, the environment must be configured. It is recommended to use the ITMv1 script for this, which simultanesouly sets i) the database environment (to the private database of the user) ii) the UAL libraries environment iii) the Kepler environment.

source $ITMSCRIPTDIR/ITMv1 KEPLERFOLDER
	MACHINENAME DATAVERSION

e.g.:

source $ITMSCRIPTDIR/ITMv1 kepler tore_supra 4.08a

This scripts does not prevent you from using databases from other users or the public one, you must then use the UAL function euitm_open_env in your program to do so.

The ITMv1 script uses the two following scripts: to set the database environment variables (mandatory prior UAL usage), use:

source $ITMSCRIPTDIR/set_itm_data_env USERNAME
 MACHINENAME DATAVERSION

e.g.:

source $ITMSCRIPTDIR/set_itm_data_env myname jet 4.08a

Then to set the path to the right UAL libraries, use:

source $ITMSCRIPTDIR/set_itm_env DATAVERSION

e.g.:

source $ITMSCRIPTDIR/set_itm_env 4.08a

svn co https://gforge6.eufus.eu/svn/ual
