WF4 - Persistence: Error using ParallelForEach

WF4 - Persistence: Error using ParallelForEach

Postby mcanals » Mon 08 Oct 2012 08:09

We are using the OracleInstanceStore, Devart version 6.80.
And when we use a ParallelForEach in a workflow then we got the next exception saving the workflow instance:

Instance c4a49a9e-13dd-4dd0-adea-deb8ac659cff has aborted. Error: System.Runtime.DurableInstancing.InstancePersistenceCommandException: The execution of the InstancePersistenceCommand named {urn:schemas-microsoft-com:System.Activities.Persistence/command}SaveWorkflow was interrupted by an error. ---> Devart.Data.Oracle.OracleException: ORA-01461: can bind a LONG value only for insert into a LONG column

Any idea where it comes from?

Thanks in advance!

Please turn on the dbMonitor tool to find out which statement fails to execute. If this doesn't help to solve the issue, send us a small test project to reproduce the issue in our environment. Also specify the exact (6.80.xxx) build of dotConnect for Oracle you are using: the Tools > Oracle > About menu of Visual Studio.

Return to dotConnect for Oracle
