How to Diagnose Oracle Data Pump-如何给数据泵添加诊断信息

11g的数据泵（expdp/impdp）还是有很多bug，经常遇到莫名的卡死现象，让人不知所措，最近看了一篇文章，其实在进行数据泵导出导入的时候，可以进行日志跟踪
Parameter: TRACE
启用跟踪功能，只需要在DataPump(expdp)或DataPump(impdp)的时候添加一个trace参数，对其指定一个7位数的十六进制。前三个数字启用跟踪特定的数据泵组件,而通常最后四位数字为:0300。任何前导零的可以省略,跟踪参数指定的值是不区分大小写的。
TRACE = 04A0300
or:
TRACE=4a0300
注意该参数的使用必须要有特定的权限，否则会报ORA-31631错误
% expdp scott/tiger DIRECTORY=my_dir DUMPFILE=expdp_s.dmp LOGFILE=expdp_s.log TABLES=emp TRACE=480300 Export: Release 10.2.0.3.0 - Production on Friday, 19 October, 2007 13:46:33 Copyright (c) 2003, 2005, Oracle. All rights reserved. Connected to: Oracle Database 10g Enterprise Edition Release 10.2.0.3.0 - Production With the Partitioning, Oracle Label Security, OLAP and Data Mining Scoring Engine options ORA-31631: privileges are required这种情况，我们只需要授予 EXP_FULL_DATABASE 或者IMP_FULL_DATABASE角色
CONNECT / AS SYSDBA GRANT exp_full_database TO scott; % expdp scott/tiger DIRECTORY=my_dir DUMPFILE=expdp_s.dmp LOGFILE=expdp_s.log TABLES=emp TRACE=480300
这里的参数为480300，其他Trace的参数及跟踪的数据泵组件对应的例子有：
-- Example of combination (last 4 digits are usually 0300): 40300 to trace Process services 80300 to trace Master Control Process (MCP) 400300 to trace Worker process(es) -- + 4C0300 to trace Process services and Master Control and Worker processes生成的跟踪日志的格式一般如下：
-- Run a Data Pump job with full tracing: -- This results in two trace files in BACKGROUND_DUMP_DEST: -- Master Process trace file: <SID>_dm<number>_<process_id>.trc -- Worker Process trace file: <SID>_dw<number>_<process_id>.trc -- And one trace file in USER_DUMP_DEST: -- Shadow Process trace file: <SID>_ora_<process_id>.trc
如何找到参数文件的位置？
Data Pump trace files 写在BACKGROUND_DUMP_DEST 和USER_DUMP_DEST.
<strong>Data Pump Master Control Process (MCP).</strong> Format : <SID>_dm<number>_<process_id>.trc Example: ORCL_dm00_2896.trc or: ORCL_dm01_3422.trc (for second active Master Control Process) Location: BACKGROUND_DUMP_DEST or <ADR_HOME>/trace <strong>Data Pump Worker Process trace file.</strong> Format : <SID>_dw<number>_<process_id>.trc Example: ORCL_dw01_2936.trc or: ORCL_dw01_2844.trc and ORCL_dw02_2986.trc (if PARALLEL=2) Location: BACKGROUND_DUMP_DEST or <ADR_HOME>/trace <strong>Data Pump Shadow Process trace file.</strong> Format : <SID>_ora_<process_id>.trc Example: ORCL_ora_3020.trc Location: USER_DUMP_DEST or <ADR_HOME>/trace
