The Sunderland winger was impressive during his 30 minutes on the pitch as he played a part in the international friendly.
The 23-year-old had vented his fury at boss Giovanni Trapattoni after he was left on the bench in Friday night's World Cup qualifier against Kazakhstan.
He was later pulled in front of the squad to apologise ahead of Tuesday's match.
Debutant Robbie Brady, who is yet to play a game for his club Manchester United, stole the show as he scored one of the four Irish goals of the night and set up two more.
Brady helped set up Shane Long's opener. The winger then smacked home a volley to make it 2-0 and he set up Kevin Doyle for the Republic's third while Alex Pearce added a fourth after Eid Al-Farsi had scored a consolation goal for Paul Le Guen's side.
Oman are ranked 53rd in the world. The easy win will give Trapattoni more confidence as he remains under pressure following the country's poor performance at Euro 2012.
The Republic of Ireland continue their qualifying campaign for the 2014 World Cup against Germany in Dublin next month.
