The non-CDB architecture is deprecated in Oracle Database 12c, and may be desupported and unavailable in a release after Oracle Database 12c Release 2. Oracle recommends use of the CDB architecture.
Note:
There remain a small number of features that do not work with the CDB architecture (see README, section 2.2.1 "Features Restricted or Not Available for a Multitenant Container Database"). If you need these features, then continue to use the non-CDB architecture until your required feature works with the CDB architecture.来自 “ ITPUB博客 ” ,链接:https://blog.itpub.net/7199859/viewspace-1794520/ ,如需转载,请注明出处,否则将追究法律责任。
