I need some help from Oracle and UNIX expertise point of view.
I have two tables, METADATA_A and METADATA_B. I need to switch loading these tables. If we load METADATA_A today, the following
week we would have to load METADATA_B.
There is a public synonym "METADATA" that sits on top of these two tables.
1) Find out which table is in use right now..
2) Truncate opposite table
3) Load opposite table
4) Validate by doing a count * on the table to check the rows loaded.
5) Finally, switch synonym
Can this be achieved using shell script? Please advice.
I have been tasked with archiving Oracle tables. The data is on raw devices, and possibly will span multiple logical volumes.
Has anyone ever had to do this? How did you accomplish it?
Any references to accomplish this would be greatly appreciated.
Thanks, (2 Replies)

drop_table
DROP TABLE(7) SQL Commands DROP TABLE(7)NAME
DROP TABLE - remove a table
SYNOPSIS
DROP TABLE [ IF EXISTS ] name [, ...] [ CASCADE | RESTRICT ]
DESCRIPTION
DROP TABLE removes tables from the database. Only its owner can drop a table. To empty a table of rows without destroying the table, use
DELETE [delete(7)] or TRUNCATE [truncate(7)].
DROP TABLE always removes any indexes, rules, triggers, and constraints that exist for the target table. However, to drop a table that is
referenced by a view or a foreign-key constraint of another table, CASCADE must be specified. (CASCADE will remove a dependent view
entirely, but in the foreign-key case it will only remove the foreign-key constraint, not the other table entirely.)
PARAMETERS
IF EXISTS
Do not throw an error if the table does not exist. A notice is issued in this case.
name The name (optionally schema-qualified) of the table to drop.
CASCADE
Automatically drop objects that depend on the table (such as views).
RESTRICT
Refuse to drop the table if any objects depend on it. This is the default.
EXAMPLES
To destroy two tables, films and distributors:
DROP TABLE films, distributors;
COMPATIBILITY
This command conforms to the SQL standard, except that the standard only allows one table to be dropped per command, and apart from the IF
EXISTS option, which is a PostgreSQL extension.
