Alfresco x64 位连接器使用 .NET 配置文件的 x64 位。配置文件位于:
C:\Windows\Microsoft.NET\Framework\v2.0.50727\CONFIG\machine.conf
C:\Windows\Microsoft.NET\Framework\v4.0.30319\Config\machine.conf
C:\Windows\Microsoft.NET\Framework64\v2.0.50727\CONFIG\machine.conf
C:\Windows\Microsoft.NET\Framework64\v4.0.30319\Config\machine.conf
请记住,问题在于缺少提供者。因此,要解决此问题,您必须在 DbProviderFactories 标记之间插入缺少的提供程序,如下所示:
<DbProviderFactories>
<add name="Odbc Data Provider" invariant="System.Data.Odbc" description=".Net Framework Data Provider for Odbc" type="System.Data.Odbc.OdbcFactory, System.Data, Version=2.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089"/>
<add name="OleDb Data Provider" invariant="System.Data.OleDb" description=".Net Framework Data Provider for OleDb" type="System.Data.OleDb.OleDbFactory, System.Data, Version=2.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089"/>
<add name="OracleClient Data Provider" invariant="System.Data.OracleClient" description=".Net Framework Data Provider for Oracle" type="System.Data.OracleClient.OracleClientFactory, System.Data.OracleClient, Version=2.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089"/>
<add name="SqlClient Data Provider" invariant="System.Data.SqlClient" description=".Net Framework Data Provider for SqlServer" type="System.Data.SqlClient.SqlClientFactory, System.Data, Version=2.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089"/>
<add name="Npgsql Data Provider" invariant="Npgsql" description=".Net Framework Data Provider for PostgreSQL" type="Npgsql.NpgsqlFactory, Npgsql, Version=2.0.13.91, Culture=neutral, PublicKeyToken=5d8b90d52f46fda7"/>
<add name="MySQL Data Provider" invariant="MySql.Data.MySqlClient" description=".Net Framework Data Provider for MySQL" type="MySql.Data.MySqlClient.MySqlClientFactory, MySql.Data, Version=6.5.4.0, Culture=neutral, PublicKeyToken=c5687fc88969c44d"/>
<add name="Microsoft SQL Server Compact Data Provider 4.0" invariant="System.Data.SqlServerCe.4.0" description=".NET Framework Data Provider for Microsoft SQL Server Compact" type="System.Data.SqlServerCe.SqlCeProviderFactory, System.Data.SqlServerCe, Version=4.0.0.0, Culture=neutral, PublicKeyToken=89845dcd8080cc91"/>
</DbProviderFactories>
通过此插入,下次 DbClient 将尝试打开数据库并获取所要求的提供程序,它将成功。
