  ORA-00959 impdp tips

Oracle Database Tips by Donald BurlesonApril 3, 2015

Question:  I se where I get an ORA-00959 with impdp because my schema name is specified in the dump file in lowercase. 

I got it to work by creating a new tablespace as my_ts (in lower case) and then executing the following and the data were imported.

impdp VDIADMINT/scott@orcl DIRECTORY=kdump dumpfile=VDIADMIN_DUMP.DMP remap_schema=myschema:MYSCHEMA

If it's possible to force remap_tablespace to take lower case tablespace name or if anyone can explain this to me?

Answer:  In your original exported database, the tablespace and schema names where created in lowercase, by enclosing the names in double-quotes, not a good idea:

create table "mytab"  . . .
create tablespace "mt_ts" . . .
create user "my_schema" . . .

These cause the entries to be stored in the data dictionary as lowercase.

The docs say:

By default, table names in a database are stored as uppercase.

If you have a table name in mixed-case or lowercase, and you want to preserve case-sensitivity for the table name, then you must enclose the name in quotation marks.

The name must exactly match the table name stored in the database.

In parameter file mode: TABLES='"Emp"'
