It seems I found the answer from Oracle certification FAQ:
How long are my exam results valid? For instance, if I took the 1Z0-007 exam in 2002, is it still valid to use toward my 10g DBA OCA certification?
Exam results remain valid. They do not expire. If you took an exam at any time, it will remain valid to use in any certification path in which it is valid.
