According to the theory of spectral line formation in the state of non-local thermodynamic equilibrium and by using the software package FAC for the relativistic multi-configuration atomic processes, the X-ray and EUV spectra of Be-like oxygen ions are simulated. The effects of indirect processes on the X-ray and EUV spectra of Be-like O ions are probed. In the situation of the typical cosmical plasma density (ne = 1010/cm3), three models are adopted. For different temperatures, the processes of formation of X-ray and EUV spectra are simulated, and the contributions of indirect processes to the formation of spectral lines are analyzed and compared. Besides, their rate coefficients are given. It is found that in the process of spectral line formation, the indirect processes have exceedingly important effects.
