You did it.
| Quote: | i don't want to disable my indexes
|
From doc:
| Quote: | SQL*Loader leaves indexes in an Index Unusable state when the data segment being loaded becomes more up-to-date than the index segments that index it. The following conditions cause a direct path load to leave an index or a partition of a partitioned index in an Index Unusable state:
* SQL*Loader runs out of space for the index and cannot update the index.
* The data is not in the order specified by the SORTED INDEXES clause.
* There is an instance failure, or the Oracle shadow process fails while building the index.
* There are duplicate keys in a unique index.
*Data savepoints are being used, and the load fails or is terminated by a keyboard interrupt after a data savepoint occurred.

From doc:
| Quote: | During a direct path load, some integrity constraints are automatically disabled. Others are not.
The constraints that remain in force are:
* NOT NULL
* UNIQUE
* PRIMARY KEY (unique-constraints on not-null columns)
The following constraints are automatically disabled by default:
* CHECK constraints
* Referential constraints (FOREIGN KEY)

Use external tables.
