ORA-03146 when updating a table with BLOB column

in Windows Oracle Data Access Components (MOSC) 1 commentQuestion

Hello, we are experiencing problems with updating a table record BLOB column. We get "ORA-03146: invalid buffer length for TTC" field error.

We basically are saving e.g. PDF attachments to the DB, using NHibernate.

The problem occured after upgrade from Oracle 12.0.1.2 to 19c (19.3.0.0), now the error is occuring in a larger scale.

Probably, we need to patch the instance.

Platform:

OS: Windows 2012 Server

NHibernate verion 4

Oracle.DataAccess version: 4.122.19.1

Howdy, Stranger!
