ORA-600 [kdsgrp1] Generated When Table Contains a LONG

(Doc ID 735435.1)

Last updated on SEPTEMBER 27, 2012

Applies to:

Oracle Server - Enterprise Edition - Version 10.2.0.1 to 11.1.0.7 [Release 10.2 to 11.1]
Information in this document applies to any platform.

Symptoms

A simple select statement fails intermittently with ORA-600 [kdsgrp1].   This error can also be seen when DML is occurring on the table.

An "analyze table <table name> validate structure cascade" does not produce any errors.

The stack trace looks like the following:

kdsgrp <- kdsfbr <- kafept <- opigln <- kpov2lng <- kpofcr <- qertbFetchByRowID

If ORA-600 [KDSGRP1] is raised intermittently, but the index structure is fine, then it's likely you hit this bug.

Changes

The error started after a primary key was added to the table.
