log4Net日志插入到ORACLE

在配置文件中增加如下：

    <!--记录到oracle数据库方式-->
    <appender name="AdoNetAppender_Oracle" type="log4net.Appender.AdoNetAppender">

特别需要注意到是：commandText value 中的SQL语句，如果库中有多个表空间，必须在语句中把表空间加上，如：

="INSERT INTO NEWHCMS2.SYS_OPERATORLOG (KEYID, USER_ID, USER_NAME, CURRENT_DATE, SYS_NAME, OPERATOR_TYPE, OPERATOR_PAGE, COMPUTER_IP, COMPUTER_NAME, NOTE) VALUES (SEQ_SYS_OPERATORLOG.NEXTVAL, :operator, :log_level, :log_level, :log_date, :browser, :logger, :thread, :ip, :message, :error)"

NEWHCMS2就是表空间名；

还有就是声明了的参数，都必须在SQL语句中使用；

如 :operator, :log_level, :log_level, :log_date, :browser, :logger, :thread, :ip, :message, :error

在配置中声明了 它们，就 必须在SQL中使用，也就是说SQL语句中的参数与声明中必须一一对应，声明中不能用多余的参数声明；如：:state这个参数在SQL语句中没有用到，也不能在声明中出现，必须把它屏蔽！
