OraOps崩溃w3wp.exe进程 [英] OraOps crash w3wp.exe Process

问题描述

我们正在从Oracle 11g升级到12c.在Microsoft Azure中的新VM计算机上.

We are upgrading from Oracle 11g to 12c. On a new VM machine in Microsoft Azure.

在对我们的网站C#的特定调用中，视觉上似乎什么都没有发生，但是我们希望生成PDF.屏幕上没有错误，但是所有会话变量都丢失了.因此，我怀疑IIS池崩溃会自行重启.

On a specific call on our Website C#, visually nothing seems to happen, but we are expecting a PDF to be generate. We got no error on the screen, but all our sessions variables are lost. So I suspected a IIS Pool Crash that restart itself.

在EventViewer中，我们有4个条目:

经过大量的调整和测试后，我激活了Oracle跟踪.我怀疑在DataReader处置之前会关闭错误的连接.

After a lot of tuning and testing I activated the Oracle Tracing. Where I suspect a Wrong Connection Close before a DataReader Dispose.

推荐答案

最后，我们在关闭数据库连接的方式上遇到了问题.

Finally, we add a problem with the way we were closing our DB Connection.

出于某种原因，Oracle 11不在乎，但是12c要求更多.

For some reason Oracle 11 doesn't care but 12c ask for more.

似乎我们在某个地方处理了连接错误，因此我们修改了整个源代码以重构代码.我们使用使用子句"，尝试/捕获/最后，在必要时添加Close()和Dispose()指令(并在不需要时删除一些).

It's seem that somewhere we were mishandling the connection, so we revised our entire source for refactoring our code. We use "Using Clause", Try/Catch/Finally, add Close() and Dispose() instruction if necessary (and remove some when not needed).

我们还在我们的connectionString上添加了Pool参数，以实现更好的池管理.

We also add Pool parameters on our connectionString for better pool management.

所有这些都解决了我们的问题.

All of that fix our problem.
