ORA-12582: TNS:invalid operation, using CLOB datatype in database table

We are having 2 servers. I am working with .Net and oracle. Both the servers are having same oracle version 11g (11.2.0.1.0).

One scenario (getting values from Database table, in that one column datatype is CLOB and binding to div) is working fine in one server. But the same scenario is giving exception in another server.

The .net application log says,

2015-05-22 10:26:16,836 [152152] ERROR System.Data.OracleClient.OracleException (0x80131938): ORA-12582: TNS:invalid operation

I have searched regarding this issue, and i found only this,

Action: Not normally visible to the user. For further details, turn on tracing and reexecute the operation. If error persists, contact Oracle Customer Support.

I dint find any other solution. Also, i dont know what to do regarding this issue.

Note : All other database related things are working fine.

This is worked for me. Instead of taking the CLOB data directly, i have done like this...

DBMS_LOB.substr(VALUE, 5000) AS VALUE

Not sure, whether this the right solution. But it worked for me.
