FRIB dri­ver linac will de­liver all sta­ble heavy ion beams with beam en­ergy more than 200 MeV/u, and beam power on tar­get up to 400 kW. As the first SRF linac for high power heavy ion beams, there are many tech­ni­cal chal­lenges, and in­te­gra­tion of all the ac­cel­er­a­tor com­po­nents is im­por­tant. In this paper, major is­sues on in­te­gra­tion of the FRIB drive linac are in­tro­duced and the cor­re­spond­ing stud­ies are dis­cussed, which in­clude de­vel­op­ments of ac­cel­er­a­tor on­line model, min­i­mize un­con­trolled beam loss in the SRF linac for high power heavy ion beams, beam di­ag­nos­tic sys­tems for beam tun­ing and for ma­chine pro­tec­tion sys­tem (MPS), sec­ondary col­li­ma­tors for charge se­lec­tion of multi charge state ion beams, beam load­ing and sta­bil­ity of LLRF con­trol, proper de­gauss process with su­per­con­duct­ing (SC) so­le­noids when com­bined with SC di­pole cor­rec­tors, vac­uum sys­tem, cryo­genic and dis­tri­b­u­tion sys­tem, he­lium pres­sure drop and sta­bil­ity of the cry­omod­ules.

A data­base for model data is de­sign for the Fa­cil­ity for Rare Iso­tope Beams (FRIB) Pro­ject. The data­base schema de­sign takes most gen­eral ap­proach and is not lim­ited to FRIB mod­els. Pro­gram­mat­i­cally ac­cess to the data­base can be done through a set of Ap­pli­ca­tion Pro­gram­ming In­ter­faces (APIs). Ini­tial data pop­u­la­tion demon­strates that the data­base is suit­able for XAL ap­pli­ca­tion frame­work. The model data­base is also part of a col­lab­o­ra­tion for com­plete data­base needs among var­i­ous do­mains across an ac­cel­er­a­tor.
