获取连接超时 #2130

mychao · 2017-11-24T02:55:26Z

@wendal 请帮忙看下，谢谢。
数据库运行正常，但是突然出现了获取连接超时的异常，异常堆栈信息：
Caused by: com.alibaba.druid.pool.GetConnectionTimeoutException: wait millis 1000, active 5, maxActive 200, creating 1

maxWait太小了, 改成15000吧

mychao · 2017-11-24T03:08:06Z

@wendal maxWait是获取连接的最大等待时间，获取连接的时间应该很快吧，设置15000是不是太大了？

wendal · 2017-11-24T03:47:02Z

建oracle连接的时候,有时候很慢

huangmaomao · 2017-11-25T08:04:17Z

我这边也经常出现这个问题，怎么解决的

huangmaomao · 2017-11-25T08:13:16Z

@wendal ERROR http-nio-8080-exec-105 org.hibernate.engine.jdbc.spi.SqlExceptionHelper - wait millis 60015, active 2, maxActive 100, creating 1
用的是MySQL Server 5.7

wendal · 2017-11-25T12:34:19Z

@huangmaomao 是不是网络波动? mysql在同一个机器嘛?

话说,为啥这个issue会@我的呢??

wendal · 2017-11-25T12:36:29Z

其实你们想at的人是 @wenshao 吧, 虽然我也给druid提交过代码...

我做的是nutz系列的java框架例如 https://github.com/nutzam/nutz 和 https://github.com/nutzam/nutzboot

huangmaomao · 2017-11-25T12:49:38Z

额，是在同一台机器上面@wenshao

wenshao · 2017-11-25T13:15:17Z

creating=1标识，在建立物理连接中，是不是数据库有什么问题导致建立连接很慢？

huangmaomao · 2017-11-25T13:18:31Z

数据库和服务是在一台机器上面的，数据可以正常连接访问，服务重启之后就可以拿到连接

huangmaomao · 2017-11-25T13:22:23Z

@wenshao 网络带宽是2M的，之前有时候出现这个问题，我把版本更新到1.1.1之后用了二周，今天就频繁出现这个问题，重启服务也不行，数据库可以正常访问

wenshao · 2017-11-25T13:22:43Z

买一个阿里云的rds试试？

huangmaomao · 2017-11-25T13:35:16Z

主要是什么原因引起的呢？这个是客户的阿里云服务器，要知道原因才好给客户建议

wenshao · 2017-11-25T13:37:02Z

看不出，从报错看到的信息是物理连接在创建中

lg84300329 · 2017-11-28T12:15:48Z

＠wenshao　数据库是正常服务啊，后续的请求没有问题！为什么连接数远没有达到最大值，拿不到空闲的连接，没有新建，而是等待空闲的

active为0，还是抛出拿不到连接的异常，就突然出现那么几十次，然后又没出现过了

@lg84300329 能问下这个是怎么解决的吗？

一樣的錯誤，wait millis 60000, active 0, maxActive 20, creating 0] with root cause，求問怎麽解決的。我連的是oracle。
(Ps:oracle被人搞過之後就出了問題了，之前可以訪問的接口都訪問不了，有沒有可能是oracle庫的問題)

同样遇到了active 0，Could not get JDBC connection的问题，数据库为postgresql，druid 版本:1.0.20。

Could not open JDBC Connection for transaction; nested exception is com.alibaba.druid.pool.GetConnectionTimeoutException: wait millis 5000, active 2, maxActive 100, creating 1, createElapseMillis 9432014

详情：
数据库负载突然彪高，大量sql被阻塞，数据库进行重启然后数据库负载降低。但是其他应用程序druid连接池持续报错连接获取超时。数据库负载很低，连接很少， Druid 活跃连接只有2 但是获取不到新连接，数据库挂掉后 druid连接池不会自动恢复吗？

同样遇到这个问题。。。。
先升级mysql驱动试试。

digdeep126 · 2020-10-12T07:04:23Z

升级 mysql-connector-java 到5.1.48，升级druid到 1.1.24版本之后，已经稳定运行了三周，再也没有出现这个错误了！！！！！

KANLON · 2020-10-13T13:30:43Z

我解决了这个问题，我这里的理由是由于设置了dataSource.setBreakAfterAcquireFailure(true);这个配置导致了。由于数据库网络或者其他原因导致服务连接不上数据库几秒，然后由于上面那个配置了true之后，如果数据库连接池发现链接不上，就会彻底将该数据源标识为不可用，导致一直获取不到的链接。

设置这个的原因是我有些数据库是链接不上的，但是我不想总是打印出错误日志，druid这里的默认策略是，如果连不上数据库，会每隔30秒就是链接一次数据库

可以通过不断查询要链接的数据库，然后，中途停止数据库服务的，1，2分钟后，然后再启动起mysql，然后观察是否会获取不到链接的。

我觉得，即使设置了setBreakAfterAcquireFailure(true)这个，但是获取数据库链接池链接的时候应该也再去链接一下mysql是否能链接成功，而不是直接标识该数据源不可用了，然后不返回数据源链接了，希望druid那里能修改一下

// 获取连接失败将会引起所有等待获取连接的线程异常,但是数据源仍有效的保留,并在下次调用getConnection()的时候继续尝试获取连接 。如果设为true,那么尝试指定次数后获取连接失败后该数据源将申明已经断开并永久关闭.默认为false 
dataSource.setBreakAfterAcquireFailure(true);

超诡异的，明明配置maxActive为5，但这里的 activeCount 居然是 7，然而我用 jmap 查看存活的 ConnectionImpl 却只有 1 个。这些统计数据感觉就不太准确（另一个pod的 activeCount 始终为0，但我已经发请求查询数据库并成功返回了，jmap 返回 4 个连接）。

druid 版本为 1.2.3

leter · 2021-06-10T04:39:40Z

我oracle数据库，经常偶发性的出现这个问题，每次重启之后又变好了。搞不清楚是应用的问题还是数据库的问题，应用和数据库我每个礼拜重启一次的。看数据库的awr日志又好像是更新的时候导致锁表的问题。真的不知道怎么解决

yobuke · 2021-06-15T03:49:23Z

@wenshao 我们场景是使用druid连接池获取connection后使用jdbc对mysql读写，因为这样比较轻量。我们不希望滥用数据库连接，因为设置的maxActive是50。计划任务会起100个线程，每个线程从datasource获取connection，执行完批量任务后会调用connection.close()返还连接给连接池。但是现在的问题是执行完50个线程之后，会报getConnectionTimeoutException，我理解应该是前面的50个线程还没有释放连接，导致后面的线程获取不到。请问是什么参数设置的不对吗，或者需要设置什么参数来解决这个问题？

这种情况只能增加maxActive

ypcfly · 2021-08-12T07:49:19Z

遇到相似的问题，我们mysql是16C32G的配置，数据库最大连接 1500，waitTime_out是600。druid配置maxActive 500，经常报：
Cause: com.alibaba.druid.pool.GetConnectionTimeoutException: wait millis 6000, active 5, maxActive 2000, creating 1, createElapseMillis 60231这个错。到现在也不知道是什么问题？？有没有解决的。配置如下：

找到原因了，是应用的问题，应用在某个地方卡住一直不提交事务，我建议各位先排除应用的问题，然后设置一下数据库的超时执行时间，一旦超时就返回异常，保证不会一直占用链接，一般能解决这类问题。

一般是因为慢sql导致的链接池被占用，新请求无法获取到新的链接导致的，自己按照自己的业务提高maxwait time即可
