今天接到客戶的服務情求，他們的GoldenGate復制出現故障，我覺得他們的問題挺有代表性，于是拿出來給大家分析一下。

????錯誤描述：

????數據投遞進程abend，在日志報告中的錯誤提示如下：

????2010-02-01 17:19:18??GGS ERROR????103??Discard file (./dirrpt/rep1.dsc)??????exceeded max bytes (10000000).

問題分析：

????根據錯誤我們可以看出直接引起GoldenGate進程停止的原因是discard文件被寫滿了，是什么原因造成discard文件被寫滿的呢？從discard文件中我們看到是發生了ORA-01653: unable to extend 錯誤，看到這里我相信大家都知道該怎么處理了吧，我們只要擴展這個aaa.TB_LVY_TEMPINVOIC對象所在的表空間的大小即可。

?

問題處理：

????1、找到相關對象存儲的表空間；

????舉例：select owner,table_name,tablespace_name from dba_tables

????2、執行表空間擴展?

????舉例：??ALTER TABLESPACE tbs_03
????ADD DATAFILE 'tbs_f04.dbf'
????SIZE 100K
????AUTOEXTEND ON
????NEXT 10K
????MAXSIZE 100K;
