Storage Preferences

This section discusses the types associated with storage preferences.

The CTXSYS.DEFAULT_STORAGE storage preference uses the BASIC_STORAGE type.

Here are the storage preferences:

• The CTXSYS.XQFT_LOW preference disables the persistence of secondary XML representation into $D table to save index storage space.

  • xml_save_copy = FALSE

  • xml_forward_enable = FALSE

• The CTXSYS.XQFT_MEDIUM preference enables the persistence of secondary XML representation into $D table to reduce the time spent on post index xquery evaluation, if needed.

  • xml_save_copy = TRUE

  • xml_forward_enable = FALSE

• The CTXSYS.XQFT_HIGH preference enables the persistence of secondary XML representation into $D table and forwards the index into $O to reduce the time spent on post index xquery and xquery full text expression evaluation, if needed.

  • xml_save_copy = TRUE

  • xml_forward_enable = TRUE
