DataPump Export doesn't extract the Lob Storage Parameters in the dump file for global temporary tables.
- On source database, a global temporary table is created with the following clause for lob storage:
create global temporary table <TABLE_NAME> (COL1 number, COL2 clob) lob (COL2) store as basicfile (enable storage in row retention max cache reads);
- Checking the dump file created by the export and generating the sql file for that table on the source database shows:
CREATE GLOBAL TEMPORARY TABLE "<SCHEMA>"."<TABLE_NAME>"
( "COL1" NUMBER,
ON COMMIT DELETE ROWS ;
==> DDL statement is incorrect as Lob Storage Parameters clause is missing.
