Which versions are you using for:

Toad
Oracle client
Oracle server

Hello!

Toad : 15.1
Oracle client 12.2
Oracle server : 19 and 12.2

Thanks. I believe this is an OS error, not coming from our source directly.

Are you running from a network drive? If so, try installing Toad locally instead.

No, it's installed direct in my PC

I've just been googling the error code for clues. It seems to be caused either by network connectivity problems, or paging problems with the application. I don't think it's anything directly in Toad. I think Toad is having problems in your environment.

What about your Oracle client? Installed locally or on the network somewhere?

Do you have plenty of memory?

What happens if you try to connect with SQL*Plus to the same database?

Oracle client is installed locally was well.
SQLplus is not working, I've not realized it, but it's very curious to have sqldev working.

SQL Developer has different connection methods than SQL*Plus and Toad.

You could try downloading the Toad 16.0 beta version. This version lets you connect to the database without using an Oracle client at all. (You can actually do that in 15.1 also but it's not as convenient).

if you do that, keep version 15.1 installed. When you install the beta, it will copy settings from version 15.1, but then each version will have its own copy of settings.

We are close to the official 16.0 release, so this beta version is almost identical to what will become the official version.

Hello,

Just installed the last version of Toad 16.2.98.1741 and still have the same problem.

Do you have any idea?

Are you still using the same 12.2 client that you were using last year? Is SQL*Plus still having troubles? If you haven't done so already try installing a newer client like 18c.

Hello,

I installed oracle client 19c before update my toad application.

Best regards,

Marcio

Does SQL*Plus work? Previously you mentioned that it did not. You may need the Microsoft Visual Studio redistributable. See the Instant Client Installation for Microsoft Windows 64-bit section in the documentation. Check your installed software at Add/Remove Programs and see if you have the required version installed. If you do not, install it and test again.

Hello!

I found the root cause, the problem was that I was running oracle server in my laptop, I uninstalled that and now it's working well.
