Chapter 10. Managing Indexes

4.3. Backwards Compatibility and Migration

While current versions of Directory Server can support the old database design, only the new design is supported for this and later releases of Directory Server.

Upon startup, the server will read the database version from the DBVERSION file, which contains the text Netscape-ldbm/6.2(old database version), Netscape-ldbm/7.1(new database format), or bdb/4.2/libback-ldbm(new database format). If the file indicates that the old format is used, then the old code is selected for the database. Because the DBVERSION file stores everything per-backend, it is possible to have different database formats for different individual backends, but the old database format is not recommended.

All databases must be migrated to Directory Server 8.0 when the system is upgraded. Migration is supported for Directory Server 6.x versions, and for releases earlier than version 6.x, dump the databases be dumped, and install Directory Server fresh. Migrating databases is covered in the Directory Server Installation Guide.

Also, the index sizes can be larger than in older releases, so you may want to increase your database cache size. To reconfigure your cache size, look up the nsslap-dbcachesizeentry in the Directory Server Configuration, Command, and File Reference.

Table 10.7, “Attribute Name Quick Reference Table” lists all attributes which have a primary or real name as well as an alias. When creating indexes be sure to use the primary name.
