ORA-00600 [kollasg:client-side tmp lob]

In this Document

APPLIES TO:

Oracle Database – Enterprise Edition – Version 11.1.0.6 and later
Information in this document applies to any platform.

SYMPTOMS

An OCI-based application compiled with the 11.1.0.7 client [connecting to 11.2 db] reading a CLOB field being fetched using OCISmtFetch2 fails with an ORA-00600 [kollasg:client-side tmp lob].

CAUSE

The CLOB field being fetched needs to be initialized, as when fetching a uninitialized LOB column (ie) without any LOB locator is causing the ORA 600 error.
 

SOLUTION

Initialize the CLOB field/column with empty_clob(), either on INSERT or after the row is inserted via an UPDATE.
