Index was outside the bounds of the array. in Managed ODP.NET 19.3

user1111031Jul 22 2021 — edited Jul 22 2021

Hi,
I'm receiving the following index out of bounds error when using the ODP.NET 19.3 Managed driver:
Index was outside the bounds of the array.
at OracleInternal.ServiceObjects.DataUnmarshaller.StartAccumulatingColumnData(Int32 currentRow, Int32 columnIndex, List`1 rowDataSegments)
at OracleInternal.TTC.Accessors.Accessor.GetInternalDataRef(DataUnmarshaller dataUnmarshaller, Int32 currentRow, Int32 columnIndex, Byte[]& dataByteRep, Int32& dataOffset, Int32& dataLength)
at Oracle.ManagedDataAccess.Client.OracleDataReader.GetDecimal(Int32 i)
at Oracle.ManagedDataAccess.Client.OracleDataReader.GetValue(Int32 i)
at Oracle.ManagedDataAccess.Client.OracleCommand.ExecuteScalar()

My program is running multithreaded with each thread having its own ODP.NET connection and command instances. The threads should not be sharing any ODP.NET resources, yet I still see this error. We're using the .NET Framework version of ODP.NET released with 64-bit ODAC 19.3, not .NET Core.
Does anyone have any experience with this or know of any way to resolve this issue?

Hello!

This problem has been fixed in the latest patch, so updating your compiler will help:

$ cat b.cc

    static constexpr char16_t kFallbackPaddingString[] = u" ";

$ CC -g  a.cc -std=c++11 -V

CC: Studio 12.6 Sun C++ 5.15 SunOS_i386 Patch 152716-03 2019/04/10

Are those patches available somewhere for Solaris 10?

Maxim Kartashev-Oracle

Yes, all patches for Studio are made available both for Solaris 11 and 10. Patches for Solaris 10 can be downloaded through MOS (support.oracle.com). You'll need a support contract to do that.
