Entity Framework Transaction Error ORA-00600

[markaw]

Hi,

I'm trying to perform simple transaction with EF and dotConnect like this:

Code: Select all

            using (OwEntities Context = new OwEntities())
            {
                using (System.Transactions.TransactionScope TransactionScope = new System.Transactions.TransactionScope())
                {
                    EaiArt EaiArt = new EaiArt();
                    EaiArt.Code = "Test";
                    Context.AddToEaiArt(EaiArt);
                    Context.SaveChanges(false);
                    EaiJob EaiJob = new EaiJob();
                    EaiJob.Code = "Test EaiJob " + EaiArt.SysEAIART;
                    Context.AddToEaiJob(EaiJob);
                    Context.SaveChanges(false);
                    Context.AcceptAllChanges();
                }
            }

I'm getting a Devart.Data.Oracle.OracleException : ORA-00600: Interner Fehlercode, Argumente: [setiso02], [272768515], [], [], [], [], [], [] right after the second Context.SaveChanges(false). Am I doing something wrong here?

Best regards,
Mak

Thank you for the report, this problem is already fixed in dotConnect for Oracle 5.20 Beta.
The 5.0.25 Release build with this fix will be available this week.
As a temporary workaround you can use TransactionScope with TransactionOptions.IsolationLevel set to ReadCommitted.
