Before we have been to visit a company's test library, now needs to be developed in the field, the site of the Orcal server has been installed 12C , we do not intend to reload server-side orcal, so we will be our own computer The orcal client is reloading to 10.2, trying to match the 12C client, but 10.2 of the client and 12C server can not communicate at all, we try to downgrade the server-side orcal to 11g, we can normally access the data.
Summary: Orcal server and client version compatibility issues, for the time being the client's 10.2 and 11g servers can be normally accessed.
