For FL5 we must simply link with IBM-zLib. For FLAM4 we must expand the ADC algorithm to Support the RFC1951/52. |
(0000186) Falk Reichbott (administrator) 2013-12-18 07:38 |
To support deflate and inflate as part of the ADC mode in FLAM4 a new environment variable are required to enforce the use of the Software optimised algorithmen of limes or the GZIP (required for zEDC harware) compression. FL_ADC_ALGORITHM=AUTO # Default will choose automatically the best algorithm FL_ADC_ALGORITHM=GZIP # Always use GZIP (also if no hw accelorator available) FL_ADC_ALGORITHM=LIMES # Always use software optimised compression (also if zEDC available) To be backward compatible the envar must be set to LIMES. AUTO will allways be the default if not GZIP or LIMESW set. |
