New Features in Directory Server

This section describes the new features that were provided in Directory Server 7.0.

New DB Entry Format

To reduce the database entry size, the existing database entry format is changed. The internal representation of an entry changed from an ASCII LDIF format to a tagged binary format. The data stored in the database does not have the characteristic starting of dn: anymore, the first byte of an entry being a value bigger than 0xE0 (hence all values 0xE0 to 0xFF are to be considered reserved for internal use).

For compatibility reasons entries can be a mix of LDIF and binary representations, but any modification will write the entry in binary format.

Suffix entries data can be compressed when written to disk to minimize their disk footprint. Compression is enabled according to the settings of the compression-mode and compression-entries properties,

For additional information, refer to the Chapter 8, Writing Entry Store and Entry Fetch Plug-Ins, in Oracle Fusion Middleware Developer’s Guide for Oracle Directory Server Enterprise Edition.

Copyless Restore

To save disk space, you can restore a server by moving files in place of copying them. You can perform the copyless restore by setting a flag with the restore command.

For more information, see Binary Restore in Oracle Fusion Middleware Administration Guide for Oracle Directory Server Enterprise Edition

IPv6 Support on Windows

Server instances installed on Windows systems now support Internet Protocol version 6, as do instances installed on other supported operating systems.

New Command for Account Management

The dsutil command now performs the functions formerly provided by the ns-activate, ns-inactivate, and ns-accountstatus commands.

New Backup Feature

Backup operations perform a database verify on archived data when the --flags verify-db option is specified.

Index Filter Analyzer

The index filter analyzer identifies index lists where the number of entries exceeds the maximum number of indexable entries (the ALLID threshold) and monitors user searches using such index lists. To enable the index filter analyzer, use the dsconf enable-index-filter-analyzer command.
