When i am trying to unload a tablespace using incremental copy i am recieving this problem
DSNU000I DSNUGUTC - OUTPUT START FOR UTILITY, UTILID = UNLOADC1
DSNU050I DSNUGUTC - UNLOAD TABLESPACE SVC014.SVCV16D
DSNU650I # DSNUUGMS - FROMCOPY SPND.IMAGECP.SVC014.SVCV16D.G9654V00 PUNCHDDN
DSNU1232I # DSNUULCA - COMPRESSED ROW IS IGNORED BECAUSE THE DICTIONARY IS NOT AVAILABLE FOR TABLE SV.VEH_VEHICLE_T
DSNU1219I # DSNUULCA - THE NUMBER OF RECORDS IN ERROR REACHED THE LIMIT 1
DSNU012I DSNUGBAC - UTILITY EXECUTION TERMINATED, HIGHEST RETURN CODE=8
