Design of the electron and ion rings of the Jefferson Lab Electron-Ion Collider (JLEIC) features the low-beta Interaction Regions (IR) with detector solenoid, non-linear chromaticity compensation blocks (CCB), and spin rotator optics with solenoids. The high beta functions in the IR final focus quadrupoles (FFQ) and in the CCB magnets result in strong effects of errors in these magnets. Performance of the spin rotators may also be sensitive to the errors. The first part of this study includes the design of orbit correction system for both rings and evaluation of dynamic aperture (DA) with misalignment and the correction. The second part is devoted to the DA study with the FFQ non-linear field errors. The orbit correction design, the dynamic aperture, and the impact on error specifications are presented.
