Devart Exception

Post by san_eins » Fri 17 Jun 2016 06:08

Hi Team,

We are using Devart 6.3 version in our application to connect to Oracle database. We are experiencing the below exception while calling stored procedure through DevArt.

This issue occurs very rarely and not re-producible at will. Please help us resolving this issue.
Devart.Data.Oracle.OracleException (0x80004005): Internal exception in Oracle client occurred.
---> System.AccessViolationException: Attempted to read or write protected memory. This is often an indication that other memory is corrupt.
at OciDynamicType.nativeOCIStmtExecute(HandleRef , HandleRef , HandleRef , Int32 , Int32 , Int32 , Int32 , Int32 )

We are on :
• Windows 2008 Service Pack 2
• Oracle 11g (11.2.0) lient
• Dot Connect 6.3

Thanks in advance
