docker上的sql超时

[ad_1]

我正在执行使用 Docker 上托管的 SQL 数据库的测试。我在某些测试中遇到超时问题

var msSqlContainer = new ContainerBuilder()
	.WithImage("mcr.microsoft.com/mssql/server:2017-latest")
	.WithName(Guid.NewGuid().ToString()[..5])
	.WithPortBinding(1433, true)
	.WithEnvironment("ACCEPT_EULA", "Y")
	.WithEnvironment("SQLCMDUSER", "sa")
	.WithEnvironment("MSSQL_SA_PASSWORD", password)
	.WithEnvironment("SQLCMDPASSWORD", password)
	.WithCleanUp(true)
	.WithNetwork(network)
	.WithWaitStrategy(Wait.ForUnixContainer().UntilPortIsAvailable(1433))
	.Build();
await msSqlContainer.StartAsync();

var msSqlPort = msSqlContainer.GetMappedPublicPort(1433);

_databaseConnectionString = $"Server={msSqlContainer.Hostname},{msSqlPort};User Id=sa;Password={password};TrustServerCertificate=true;";

Timeout after 239.3025928 calling database. Caller:get_cust_messages_by_cust Message:Timeout expired.  The timeout period elapsed prior to completion of the operation or the server is not responding.

我尝试过的：

我尝试将“连接超时= 60”添加到连接字符串中

我使用下面的查询检查有多少个连接，我的连接数始终低于 30 个

SELECT a.*
FROM
(SELECT
DB_NAME(dbid) as DBName,
COUNT(dbid) as NumberOfConnections,
loginame as LoginName
FROM
sys.sysprocesses
WHERE
dbid > 0
GROUP BY
dbid, loginame) a
ORDER BY a.DBName, a.LoginName

解决方案1

是的，我确信可以访问数据库。在 3000 个测试中，有些测试因 Sql 超时而随机失败。

以下是我用来打开数据库连接的方法

private DbConnection GetDBConnection()
{
    var db = _sqlDBfactory.CreateConnection();
    db!.ConnectionString = _databaseConnectionString + "Initial Catalog=clients;";
    db.Open();
    return db;
}

调用示例：

using var db = GetDBConnection();
try
{
	return db.QueryFirst<string>(
		$"SELECT statment goes here... omitted purposly;
}
finally
{
	db.Close();
}
