please get support for OMI 10.63 with latest Oracle ->
Oracle 12c R2
With the impending release of on-prem Oracle Database 19c, support for 18c should be made available ASAP (especially considering that 18c is essentially a patch release of the Oracle 12.2.x product line). I strongly suspect that the only incompatibility with the 18c version occurs during the version check by OMI. Otherwise it should be functionally identical to 184.108.40.206 for OMI purposes.
