執行指令碼diagcollection.pl報錯

Oracle的RAC提供了diagcollection.pl指令碼，用來收集CLUSTER和資料庫的指令碼。不過在客戶環境中執行這個指令碼報錯。

詳細錯誤資訊為：

[root@smsdbrac1 ora_test]# $ORA_CRS_HOME/bin/diagcollection.pl -crshome=$ORA_CRS_HOME -collect

執行指令碼出現Argument list too long的錯誤，查詢MOS發現導致問題的原因CRS目錄中的檔案太多，以致於超過了shell的限制。

在11g中可以使用—afterdatevar來限制時間範圍，從而減少CRS中採集的檔案數量。

對於10.2版本，除了手工收集指令碼這個辦法外，還可以考慮手工減少日誌數量的方法。進入$CRS_HOME/log//client目錄，將所有一個月前的日誌打包並壓縮，然後刪除，再次執行diagcollection.pl指令碼即可。
