Database 12.1, "ORA-12582: TNS" by query for table with CLOB

edited Sep 15, 2014 3:53AM in Database Networking (MOSC) 5 commentsAnswered

Hi everybody,

I'm sometimes getting this error by running a query over a table with a CLOB column.

ORA-12582: TNS: Ungültiger Vorgang

The query is run from a .NET Windows application using the SYSTEM.DATA.ORACLECLIENT library from .NET Framework 4.

Database Version: Oracle Database 12c Release 12.1.0.1.0 - 64bit Production

OS: Windows Server 2012

I found something similar for the 11.2 Database but no workaround for the Oracle 12.

I would appreciate any help.

Best regards,

Daniel
