WARNING OGG-00952 Purging log history from OGG.GGS_DDL_HIST，ogg-00952purging

經常在巡檢OGG日誌的時候發現如下警告：
2013-01-18 16:52:56  WARNING OGG-00952  Oracle GoldenGate Manager for Oracle, mgr.prm:  Purging log history from OGG.GGS_DDL_HIST older than 2013-01-13 15:52:56.084114: Could not delete rows from OGG.GGS_DDL_HIST, no database specified.
2013-01-18 16:52:56  WARNING OGG-00952  Oracle GoldenGate Manager for Oracle, mgr.prm:  Purging log history from OGG.GGS_DDL_HIST_ALT older than 2013-01-13 15:52:56.084261:Could not delete rows from OGG.GGS_DDL_HIST_ALT, no database specified.
2013-01-18 16:52:56  WARNING OGG-00952  Oracle GoldenGate Manager for Oracle, mgr.prm:  Purging log history from OGG.GGS_MARKER older than 2013-01-13 15:52:56.084448: Could not delete rows from OGG.GGS_MARKER, no database specified.

開始沒有引起重視，後面發現OGG的資料表空間使用率漸漸升高。才覺得與這個有關係，於是上網查了資料。果然如此

引起這個警告的原因是，OGG做這個操作需要進入到資料庫裡面，所以我們需要在MANAGER裡面加入如下參數：
USERID OGG,PASSWORD DFASDFASFASDADFAD,ENCRYPTKEY DEFAULT

MANAGER修改參數不需要重啟進程，只用重新整理進程即可：
refresh manager

重新監控OGG ggserr.log日誌發現沒有出現上述警告
