在用root用戶啟動weblogic的時候會在所在域里產生root權限的文件，或者用root權限的文件覆蓋了部分原來存在的weblogic用戶所屬文件，當再次切換到weblogic用戶后，啟動的時候就會出現(xiàn)權限問題，所以報告上面的錯誤。這個錯誤就是因為EmbeddedLDAP.tran文件的權限變成了root的。

解決方法：

用root用戶登錄，將EmbeddedLDAP.log賦權給weblogic用戶。但是還有一系列的log文件需要賦權。索性把domains下的所有應用全部賦權。

[root@mnhj02 ~]# chown -R weblogic:weblogic domains_dir

前一個weblogic是用戶，后一個weblogic是用戶所屬組，domains_dir是文件所在的路徑。
