Log4net记录日志到Oracle 11g

试了多次，当前的Log4net都不支持记录日志到Oracle 11g数据库，于是各种搜索。

1. 下载log4net源代码进行改写

1.1 添加对Oracle.DataAccess的引用

1.2 添加OracleAppender类  点击此处下载

也可以点击此处下载编译好的 log4net.dll

2. 新建Web项目，添加对log4net.dll和Oracle.DataAccess.dll的引用，并进行Web.config配置

2.1 增加section

<section name="log4net" type="log4net.Config.Log4NetConfigurationSectionHandler, log4net" />

<log4net>
<appender name="OracleAppender" type="log4net.Appender.OracleAppender">

<commandText value="INSERT INTO LOG4NET (LOG_ID, LOG_DATE, LOG_LEVEL, LOG_IDENTITY, LOG_MESSAGE, LOG_EXCEPTION, LOG_LOGGER, LOG_SOURCE) VALUES (LOG4NET_SEQ.nextval, :log_date, :log_level, :log_identity, :log_message, :log_exception, :logger, :source)" />

3. 配置代码记录LOG。(global.asax文件中的Application_Start方法中添加如下代码)

log4net.Config.XmlConfigurator.Configure();
ILog log = LogManager.GetLogger("loginfo");
log.Info("Application Start");

create table LOG4NET
(
log_id        NUMBER not null,
log_date      TIMESTAMP(6),
log_level     VARCHAR2(255),
log_identity  VARCHAR2(255),
log_message   VARCHAR2(4000),
log_exception VARCHAR2(4000),
log_logger    VARCHAR2(255),
log_source    VARCHAR2(1000)
)

create sequence LOG4NET_SEQ
minvalue 1
maxvalue 999999999999999999999999999
start with 53
increment by 1
nocache;
