Other Logminer clients must run build() prior to mining. If build() has been run, ensure that all logfiles which comprise the gathered system dictionary have beed added. The following query, run on the system which build() was run, can be helpful in identifying the requried files. select DICTIONARY_BEGIN, DICTIONARY_END, name from v$archived_log; Minimally a set of files beginning with one which has DICTIONARY_BEGIN = ‘YES’ and all following log files through one marked DICTIONARY_END = ‘YES’ must be added.
