问题描述
我正在尝试在TransactionScope内使用ADO.NET向我的Oracle数据库中批量插入100k +项目.像这样:
I am trying to batch insert 100k+ items to my Oracle db using ADO.NET inside a TransactionScope. Like this:
using (TransactionScope transaction = new TransactionScope())
{
while(/* Pagination logic - send insertion command on every 250 items */)
{
using (OracleCommand command = new OracleCommand(query, connection))
{
command.ArrayBindCount = 250;
//Add parameters
command.Parameters.Add(":BLAH", OracleDbType.Long);
command.Parameters[0].Value = LUC.ToArray();
command.ExecuteNonQuery(); //Error occurs here after N-times inside while
}
}
transaction.Complete();
}
对于低于此(10k-30k)的项目,交易成功完成.但是,对于较高项(例如100k),我会得到 ORA-00604:在递归SQL级别%s上发生错误.
For items lower than this (10k-30k) transaction is completed successfully.However for higher items (like 100k) I get ORA-00604: error occurred at recursive SQL level %s.
如果我完全删除了TransactionScope,则在任何项目尺寸下都不会出现任何错误,它可以正常工作.
If I remove TransactionScope altogether, I don't get any error with any item size, it just works.
如何使TransactionScope处理大量项目?
How can I make TransactionScope work with huge number of items?
推荐答案
结果是,这是一个事务性超时问题.
Turns out, it was a transactional timeout problem.
增加超时后,我已成功插入列表:
After I increased the timeout, I have inserted my list successfully:
using (TransactionScope transaction =
new TransactionScope(TransactionScopeOption.Required,
new TimeSpan(0, 30, 0))) //30 minute timeout limit
