Hi Team,

Currently we have migrated to Windows 10 machine and one of our application was with PB12.6 and sometimes users faces the slowness issue and sometimes application has been get crashed and the data content is loading for long time to display after windows 10 migration.

Please find the list of issues which user has reported.

1) Slowness issue (not all time) and application crashes if any document is loading from the database (or) other interfaces

2) Datawindows error : ct_send: network packet layer: Internal net library error: Net- Library operation terminated due to disconnect

3) Datawindows error : ct_cmd_alloc: user api layer: external error The connection has been marked as dead.

4) Timestamp expired.

Can you please suggest anyidea to obvercome this issue (or) we need to migrate to PB 2017 version ( Other applications in PB 2017 version, doesnot have this problems )

Can you please Suggest

Thanks and Regards

George.

As you are aware, PowerBuilder 12.6 is not supported on Windows 10. For that support, PowerBuilder 2017 is needed. Some have had no issues with running on Windows 10. Your experience appears to be different but it is unclear that the problem is PB 12.6 running on that platform.

1. Insufficient information to really offer comments. I do run PB 12.6 on Windows 10 and have not experiences slowness or crashes. What do you specifically mean by "document loading from the database (or) other interfaces"? What is the crash details?

2) & 3) suggest database connectivity issues. What database client? Have you confirmed that the client is supported on Window 10? This is unlikely a PB issue so I would initially triage the database components.

4) What is meant by "timestamp expired".

Thanks a lot Chris for replying to my post. Please find the answers below as requested

1) We have many tabs in our application. We can switch from one tab to another tab on a in the application itself. When we are clicking on other tab, it takes some time to load the next tab (It takes 10 to 15 seconds to go to next tab), we have not faced the same issue in windows 7 machine. Sometimes not responding message box will appear and the application get freezes and unable to do any activity. We need to close the application and relaunch it again.

The documents which is transferred from web application to our power builder application can be viewed where its downloaded in the local Temp folder of user machine. When user clicks on the documents button, loading for files from database to temp folder is taking long time compared to Windows 7 machine.

2)We are using the sybase database client. Yes, sybase is supported by the Windows 10.

Please ignore the timestamp expired which i have previously mentioned in that.

Please let me know if you require any additional information to know more in detail.

I think that you need to put more focus on defining the problem. This is still too high level unless someone happens to have experienced the same symptoms.

Is there code being executed when you move tab to tab? Have you profiled/debugged that code to narrow what is slow?

You speak of a web application handling the documents but then talk about loading the files from a database? Does the document get moved from the web application into the database and then accessed by the application only from the database? How is the document loaded from the database and then stored to the temp location? Have you profiled where the time is being spent? This can be at the application and database level
