The Omanis made two changes to the side that lost to Bangladesh on Tuesday with Suraj Kumar and Khawar Ali coming in for Ayan Khan and Kaleemullah.
"We have to put up a good total and defend it," said Zeeshan.
"The pitch will play different in the second innings, a bit of spin, give freedom to our players."
Scotland's Saltires, who have won both of their matches so far, brought back Safyaan Sharif for Alisdair Evans.
"We would have been happy either way. Comfortable chasing," said captain Kyle Coetzer.
"We've got a real belief and togetherness among our group, having to win three games to top the group, if that's what we have to do, we are comfortable with that."
Victory for the winner will see them join Bangladesh, who earlier beat Papua New Guinea by 84 runs, in the Super 12s.
Sri Lanka qualified on Wednesday from Group A with either Ireland or Namibia set to join them on Friday.
