ksdbgcra: writing core file to directory ‘/u01/app/oracle/diag/rdbms/telecom/telecom/cdump‘

问题语句在：

expdp USERNAME/PASSWORD directory=ORA_DIRECTORY dumpfile=FILENAME.dmp logfile=FILENAME.log parfile=ORA_PATH_DUMPFILES/expdp_profile.par

该问题是oracle的一个bug，所以在expdp语句中需要添加一个参数：EXCLUDE=STATISTICS

expdp USERNAME/PASSWORD directory=ORA_DIRECTORY EXCLUDE=STATISTICS dumpfile=FILENAME.dmp logfile=FILENAME.log parfile=ORA_PATH_DUMPFILES/expdp_profile.par

再次去执行就没得问题了

expdp 导出用户报错ORA-07445: exception encountered:
