oracle 12c end of life

I used to have an idea that I just wanted to create an index on one or a few of these partitions, and that the other partitions didn't want to be created, and neither the local nor global index was able to achieve that requirement, but the partial Global was introduced from Oracle 12C /local Indexes for partitioned tables solves the problem by creating a local index or global index on the specified partitio

Oracle 12c agent install for windows, oracle12c There are two methods to deploy the agent in Oracle EM12c: one is to install the agent "push" directly to the managed end through the EM12c console through ssh, this method is relatively simple on the OMS and the managed end o

Label: In oracle12c, the concept of pluggable databases, the PDB, is added to allow a database container (CDB) to host multiple pluggable databases (PDB). CDB is all called Containerdatabase, the Chinese translation is a database container, the PDB is all called pluggabledatabase, you can plug and unplug the database. The following is an official document about the CDB vs. pdb diagram. In CDB, you can only create a C # #或C # #开头的用户, and if you do not add c##, you will be prompted with the error

The concept of change sets is introduced in conformance CDC. A change set can include several tables that have relationships with each other, such as a primary foreign key reference relationship. The CDC can guarantee data consistency when capturing and releasing changes in a change set. This exercise describes how to use a CDC that guarantees consistency.1 Environment PreparationSOURCE table: Odi_src. Dept,odi_src. Emp Target table: Odi_tag. DEPT, Odi_tag.
