Narrative:

Approximately 25 mins into flight, first officer noticed #2 engine oil temperature in the yellow (caution) area. We ran the applicable checklists while conferring with dispatch and maintenance control. The engine was shut down per the checklist and an emergency was declared with ATC and dispatch flight attendants were briefed for a cabin advisory and did an outstanding job of getting ready to land. We were equidistant from smf and sfo and decided to continue to sfo. I addressed the passenger and made an uneventful landing in sfo. Callback conversation with reporter revealed the following information: the reporter stated the exact component that caused the high oil temperature is unknown. The reporter said the engine was to be removed in 3 hours for teardown and overhaul.
