測試導(dǎo)數(shù)據(jù)驗(yàn)證一個(gè)其它問題，但是突然導(dǎo)入的時(shí)候一直卡主了。然后一看日志發(fā)現(xiàn)原來impdp導(dǎo)入過程中產(chǎn)生大量歸檔日志，存儲(chǔ)歸檔的空間滿了所以才卡住了

因?yàn)槭菧y試環(huán)境所以只是開啟了歸檔其它啥都沒設(shè)置，于是就默認(rèn)存放位置載db_recovery_file_dest_size 下，默認(rèn)也是4G大小。

其實(shí)解決方法也簡單，只不過想起來好久沒寫博客所以記錄一下。主要?dú)w檔滿了，我們可以通過設(shè)置限制的大小或者刪除歸檔日志來解決。但是因?yàn)槲疫@邊測試空間不多所以采用第二種方法刪除歸檔日志。

先新開一個(gè)終端，rman target /? 運(yùn)行以下命令。
