Attempted To Read Or Write Protected Memory When Dequeueing A Propagated Message (Doc ID 1328814.1)

Last updated on JULY 05, 2017

Applies to:

Oracle Data Provider for .NET - Version: 11.2.0.2 and later [Release: 11.2 and later ]
Information in this document applies to any platform.

Symptoms

When attempting to dequeue a message that was propagated from another database, ODP.Net throws memory corruption related errors such as:

Attempted to read or write protected memory
OCI-21710:Argument is expecting a valid memory address of an object

The test program for this bug comprises two parts:

insertDataToSourceDB just inserts a bunch of data into the first database. This data is propagated via AQ to the second.

DequeueMessageFromDes_DB dequeues messages from the second and should read back all data until there is none left. However it crashes after only a few rows. This number differs on each run.

If there is no data in the destination database then DequeueMessageFromDes_DB fails with an ORA-25228.
