在datax 中导数据使用过程中往往会因为,目标数据过大导致datax oom,那么可以调大datax的jvm参数来防止oom,在python命令后,使用 -jvm=”-Xms5G -Xmx 5G”来调大
当datax 导入mysql数据时,可能会因为有有数据报错,导致datax导数据会异常慢,那么可以修改mysqlwriter的writeMode模式 修改为Insert ignore 忽略报错,速度会显著提升。
如果报javaioIOException: Maximum column length of 100,000 exceeded in column异常信息,说明数据源column字段长度超过了100000字符。
需要在json的reader里增加如下配置
SqlDataAdapter只是dataset和数据库的桥接器,不是用来放数据的,数据是放在dataset中的,你的database这个方法,应该加一句myCommand fill(myDataSet),然后从dataset中读取数据。
public DataSet database(String bm, String b)
{
try{ //创建一个 SqlConnection对象
string strCon = "Integrated Security=SSPI;Initial Catalog='sujx';Data Source='8a8ed6caf0f3482';User ID='sa';Password='123';Connect Timeout=30";
SqlConnection myConn = new SqlConnection (strCon) ;
myConnOpen();
string strCom = " SELECT FROM "+bm+" where "+b ; //创建一个 DataSet对象
DataSet myDataSet = new DataSet() ;
SqlDataAdapter myCommand = new SqlDataAdapter ( strCom , myConn ) ;
myCommandfill(thismyDataSet,"bm");
myConnClose(); //关闭连接
}
catch ( Exception ex1 ) {
ConsoleWriteLine( "本地SQL数据库连接失败");
ConsoleWriteLine("连接本地SQL数据库发生错误:" + ex1ToString(), "错误!");
}
}
首先确认linux
IP,其次在win7的Oracle客户端查看tnsnamesora文件配置
(例如:X:\oracle\product\1010\Db_1\NETWORK\ADMIN\tnsnamesora)
增加配置文件内容参考如下:
数据库链接串名
=
(DESCRIPTION
=
(ADDRESS_LIST
=
(ADDRESS
=
(PROTOCOL
=
TCP)(HOST
=
LinuxIP地址)(PORT
=
1521))
)
(CONNECT_DATA
=
(SID
=
LINUX的实例名)
)
)
保存后,用“数据库链接串名”链接Linux上的Oracle:
conn
账号/密码@数据库链接串名
sqlcasqlerrtext
返回的是什么
SQLCADBMS = "MSS Microsoft SQL Server 2000"改为
SQLCADBMS = "MSS Microsoft SQL Server 6x"
题主是否想询问“datax日期为空报错怎么解决 ”?将所赋值的字段重置为空。在dataX脚本读取reader中判断时间类型的字符串为空时,赋一时间戳类型的时间默认值,这个默认值应该是容易与数据真实时间值区分的时间。在写入writer中postSql中处理,datax日期为空报错应将所赋值的字段重置为空。DataX是阿里云DataWorks数据集成的开源版本。DataX 是阿里云 DataWorks数据集成 的开源版本,在阿里巴巴集团内被广泛使用的离线数据同步工具平台。
