6.303 DBA_ROLLING_UNSUPPORTED

DBA_ROLLING_UNSUPPORTED displays the schemas, tables, and columns in those tables that contain unsupported data types for a rolling upgrade operation for a logical standby database using the DBMS_ROLLING PL/SQL package.

Use this view before you perform a rolling upgrade using DBMS_ROLLING to determine what is unsupported.

The data pertains to the container in which the view is queried.

Column	Datatype	NULL	Description
OWNER	VARCHAR2(128)		Schema name of the unsupported column
TABLE_NAME	VARCHAR2(128)		Name of the table that the unsupported column belongs to
COLUMN_NAME	VARCHAR2(128)		Name of the unsupported column
ATTRIBUTES	VARCHAR2(4000)		When the value of the COMPATIBLE initialization parameter is 20.0 or higher, this column displays the reason the table is unsupported. Otherwise, this column displays the reason the table is unsupported only if the reason is not a data type issue.
DATA_TYPE	VARCHAR2(106)		Data type of the unsupported column

Note:

When the value of the COMPATIBLE initialization parameter is 20.0 or higher, this view displays all columns in unsupported tables. Otherwise, this view displays only the unsupported columns in unsupported tables.

Note:

A rolling upgrade using DBMS_ROLLING supports more object types than a manual rolling upgrade using transient logical standby databases
