How to Diagnose Oracle Data Pump-如何給數據泵添加診斷信息
來源：程序員人生 發布時間：2014-12-26 08:36:26 閱讀次數：3944次
11g的數據泵（expdp/impdp）還是有很多bug，常常遇到莫名的卡死現象，讓人手足無措，最近看了1篇文章，其實在進行數據泵導出導入的時候，可以進行日志跟蹤
Parameter: TRACE
啟用跟蹤功能，只需要在DataPump(expdp)或DataPump(impdp)的時候添加1個trace參數，對其指定1個7位數的106進制。前3個數字啟用跟蹤特定的數據泵組件,而通常最后4位數字為:0300。任何前導零的可以省略,跟蹤參數指定的值是不辨別大小寫的。
TRACE = 04A0300
or:
TRACE=4a0300
注意該參數的使用必須要有特定的權限，否則會報ORA⑶1631毛病
% expdp scott/tiger DIRECTORY=my_dir DUMPFILE=expdp_s.dmp LOGFILE=expdp_s.log TABLES=emp TRACE=480300

GRANT exp_full_database TO scott;
% expdp scott/tiger DIRECTORY=my_dir DUMPFILE=expdp_s.dmp LOGFILE=expdp_s.log TABLES=emp TRACE=480300
這里的參數為480300，其他Trace的參數及跟蹤的數據泵組件對應的例子有：
-- 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
生成的跟蹤日志的格式1般以下：
-- 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
如何找到參數文件的位置？
Data Pump trace files 寫在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
