Binary systems constitute a valuable astrophysics tool for testing ourunderstanding of stellar structure and evolution. Systems containing aoscillating component are interesting as asteroseismology offers independentparameters for the oscillating component that aid the analysis. About 150 ofsuch systems are known in the literature. To enlarge the sample of thesebenchmark objects, we crossmatch the Two-Body-Orbit Catalogue (TBO) of GaiaDR3, with catalogs of confirmed solar-like oscillators on the main-sequence andred-giant phase from NASA Kepler and TESS. We obtain 954 new binary systemcandidates hosting solar-like oscillators, of which 45 and 909 stars are on themain sequence and red-giant, resp., including 2 new red giants in eclipsingsystems. 918 oscillators in potentially long-periodic systems are reported. Weincrease the sample size of known solar-like oscillators in binary systems byan order of magnitude. We present the seismic properties of the full sample andconclude that the grand majority of the orbital elements in the TBO isphysically reasonable. 82% of all TBO binary candidates with multiple timeswith APOGEE are confirmed from radial-velocity measurement. However, we suggestthat due to instrumental noise of the TESS satellite the seismically inferredmasses and radii of stars with $\nu_\textrm{max}$$\lesssim$30$\mu$Hz could besignificantly overestimated. For 146 giants the seismically inferredevolutionary state has been determined and shows clear differences in theirdistribution in the orbital parameters, which are accounted the accumulativeeffect of the equilibrium tide acting in these evolved binary systems. Forother 146 systems hosting oscillating stars values for the orbital inclinationwere found in the TBO. From testing the TBO on the SB9 catalogue, we obtain acompleteness factor of 1/3.
