Clusterware stack is running from /u01/app/19.0.0/grid. Is this the correct Clusterware Home?[y/n][y] y
orachk did not find the CRS binaries on ol7n1 from environment.
Set RAT_CRS_HOME to CRS_HOME or GI_HOME in current shell to override and re-run it.
eg export RAT_CRS_HOME=/u01/app/11.2.0/grid
However, GI stack is working fine in : /u01/app/19.0.0/grid
