WSO2 API 管理器对并行请求抛出异常
WSO2 API Manager Throws Exceptions for Paralle Requests
我正在使用 WSO2 API Manger 1.8.0。我为我的一个 REST API 启用了基于 SAML2BearerAssertion 配置文件的 OAuth 授权检查。
当我从 JMeter 发送并行 API 请求时。我在正确收到的 console.But 响应中看到了这些日志。

这是单个 APIM 节点的限制吗？或者我可以再做一些调整吗？
您可以看到消息“无法在 60 秒内获取连接”，这是因为线程等待 60 秒才能获取数据库连接并且无法获取连接。
在 master-datasource.xml 文件中，您可以找到每个数据源的以下元素。
<maxActive>50</maxActive>
<maxWait>60000</maxWait>
在哪里
MaxActive：一次使用的最大数据库连接数。
如果在 MaxActive 其他连接正在使用时请求连接，APIM 将等待 MaxWait 毫秒以返回连接，然后如果没有可用连接将抛出异常。
因此您可以增加 maxActive 或 maxWait 。当 运行 更多并行时。
从 WSO2 APIM 3.0.0 开始，这需要在您的 deployment.toml 文件中进行更改，因为-
[database.apim_db]
type = "h2"
url = "jdbc:h2:./repository/database/WSO2AM_DB;AUTO_SERVER=TRUE;DB_CLOSE_ON_EXIT=FALSE"
username = "wso2carbon"
password = "wso2carbon"
pool_options.maxActive=300
pool_options.maxActive 的默认值为 50，可以被该文件覆盖。可以对 shared_db 等进行类似的更改
