OraBufWriter:ReadResetResponse - Unexpected Packet received

6b87a72d-3a22-4774-a76e-a5b5dae0607e

Using Oracle.ManagedDataAccess.Core 2.19.31 to manage the connection to an onsite Oracle database.

I'm able to run queries when i build my .net core application on the IDE, but when publishing it to my local IIS server running Kestral it gives the following error:

Exception: OraBufWriter:ReadResetResponse - Unexpected Packet received.

• OracleInternal.ConnectionPool.PoolManager<PM, CP, PR>.CreateNewPR(int reqCount, bool bForPoolPopulation, ConnectionString csWithDiffOrNewPwd, OracleConnection connRefForCriteria, string instanceName, List<string> switchFailedInstNames)

• OracleInternal.ConnectionPool.PoolManager<PM, CP, PR>.Get(ConnectionString csWithDiffOrNewPwd, bool bGetForApp, OracleConnection connRefForCriteria, string affinityInstanceName, bool bForceMatch)

• OracleInternal.ConnectionPool.OraclePoolManager.Get(ConnectionString csWithNewPassword, bool bGetForApp, OracleConnection connRefForCriteria, string affinityInstanceName, bool bForceMatch)

• OracleInternal.ConnectionPool.OracleConnectionDispenser<PM, CP, PR>.Get(ConnectionString cs, PM conPM, ConnectionString pmCS, SecureString securedPassword, SecureString securedProxyPassword, OracleConnection connRefForCriteria)

• Oracle.ManagedDataAccess.Client.OracleConnection.Open()

The only relevant issue that I could find for reference is this one: OraBufWriter:ReadResetResponse - Unexpected Packet received

I've also tried turning on tracing, but nothing seems to be generating. These are the trace options I configured with OracleConfiguration before opening my OracleConnection:

                OracleConfiguration.TraceOption = 1;

                OracleConfiguration.TraceFileLocation = @C:\logs;

                OracleConfiguration.TraceLevel = 7;

Any help would be appreciated. Thanks

What operating system, OS version, and .NET Core version are you using?

6b87a72d-3a22-4774-a76e-a5b5dae0607e

The operating system is Windows 10 Pro Version 1809 (OS Build 17763.652)

IIS version  is 10.0.17763.1

I'm currently current .Net core 2.2

Nothing appears out of the ordinary with the OS and .NET Core versions being used.

The trace file would be very useful for debugging. My guess why you can't write a trace file is due to the C:\ being a Windows-protected drive that requires admin privileges. Try using another directory that doesn't require admin privileges to write to.

Thanks for you help,

I got trace files  to come up and this is the error it is returning:

In the response header just before this error comes up on the trace. The last couple of lines in the header is this:

ORA-04088: error during execution of trigger 'SYSTEM.LOGONTRG'.ORA-00604: errorred at recursive SQL level 1.

ORA-06502: PL/SQL: numeric or value error: character string buffer too small.

ORA-06512: at "SYSTEM.LOG_SESSION_INFO", line 38.ORA-06512: at line 2.

which is what i'm guessing is causing the error.

There is no existing ODP.NET bug that matches these symptoms. Can you publish your test case or email it to dotnet_us (at) oracle.com? We can try reproducing the issue in house to isolate the root cause.
