How to Add Database Reserved Words to the ODI 12c Topology (Doc ID 2617570.1)

Goal

In Oracle Data Integrator (ODI) 11g and older, a prefix was added to each of column names in the C$staging table.

For example:

create table C$_<NAME>
(
  C1_<COLUMN 1> <DATATYPE 1>... ,
  C2_<COLUMN 2> <DATATYPE 2>... ,
  C3_<COLUMN 3> <DATATYPE 3>... ,
  C4_<COLUMN 4> <DATATYPE 4>... ,
  ...
)

Starting with ODI 12c however, the prefix has been removed, and the C$ staging table now is created with column names that match the names of column from the Mapping source Datastore:

create table C$_<NAME>
(
  <COLUMN 1> <DATATYPE 1>... ,
  <COLUMN 2> <DATATYPE 2>... ,
  <COLUMN 3> <DATATYPE 3>... ,
  <COLUMN 4> <DATATYPE 4>... ,
  ...
)

Due to the change, error messages are encountered when creating the C$ table, and one of column names is a reserved word on the technology used by the staging area.

For example, "ORA-00904: invalid identifier" would be received if a COMMENT or DESC are used as column name.

For preventing such issues, the reserved word must be declared in the list of keywords for the affected technology.

How can this be achieved?
