Oracle's CEO Larry Ellison has apparently hired a posse of private dicks to track down HP's CEO Leo Apotheker.

Apotheker has not been seen since starting work with HP because he knows that Oracle wants to drag in him into court to testify against his former company SAP. SAP is in the dock as Ellison claims it nicked more than $4 billion worth of software.

According to Reuters, Oracle has subpoenaed Apotheker but HP has refused to accept the subpoena, saying the US software corporation is trying to harass him. The deep throat told Reuters that Apotheker's lawyers at Gibson Dunn & Crutcher also refused to accept the subpoena. If he is overseas, Oracle will be unable to serve him and have to await his arrival in California, the source added.
