The Service Industry Association (SIA) has filed a formal complaint with the US Department of Justice over claims that Oracle is trying to stop independent servicing organisations maintaining Sun hardware.
The SIA, which represents around 200 servicing companies, accuses Oracle of abusing its dominant market position by forcing customers to choose between having Oracle maintaining all of their systems, or none at all.
Companies that choose independent servicing organisations to maintain their systems also lose access to software upgrades.
The changes were introduced after Oracle took over Sun Microsystems, and overturned decades of coexistence between independent servicing organisations and existing customers.
"Furthermore, according to Oracle's published policies, customers who elect to use an independent servicing organisation initially but later return to Oracle support face onerous 'Return to Oracle' service restoration fees which are clearly intended to intimidate customers from leaving Oracle support in the first place," the SIA said.
Oracle charges a reinstatement fee equal to 150 per cent of the last paid support fee, or 150 per cent of the technical support list price for the system, backdated to the end of the initial contract in such circumstances, according to the SIA.
