Example 4.1. Database Directory Contents
•
db.00x files — Used internally by the database and should not be moved, deleted, or modified in
any way.
•
log.xxxxxxxxxx files — Used to store the transaction logs per database.
• DBVERSION — Used for storing the version of the database.
• NetscapeRoot — Stores the o=NetscapeRoot database created by default when the setup-
ds-admin.pl script is run.
• userRoot — Stores the user-defined suffix (user-defined databases) created at setup; for example,
dc=example,dc=com.
NOTE
If a new database is created (for example, testRoot) to store the directory tree
under a new suffix, the directory named testRoot also appears in the /var/lib/
dirsrv/slapd-instance_name/db directory.
The following is a sample listing of the NetscapeRoot directory contents.
./ entrydn.db4* parentid.db4*
../ givenName.db4* sn.db4*
DBVERSION* id2entry.db4* uid.db4*
aci.db4* nsUniqueId.db4* uniquemember.db4*
ancestorid.db4* numsubordinates.db4*
cn.db4* objectclass.db4*
Example 4.2. NetscapeRoot Database Directory Contents
The NetscapeRoot subdirectories contain an index_namedb4 file for every index currently defined in
the database. In addition to these files, the NetscapeRoot and userRoot subdirectories contain the
following files:
•
ancestorid.db4 — Contains a list of IDs to find the ID of the entry's ancestor.
•
entrydn.db4 — Contains a list of full DNs to find any ID.
•
id2entry.db4 — Contains the actual directory database entries. All other database files can be
recreated from this one, if necessary.
•
nsuniqueid.db4 — Contains a list of unique IDs to find any ID.
•
numsubordinates.db4 — Contains IDs that have child entries.
•
objectclass.db4 — Contains a list of IDs which have a particular object class.
•
parentid.db4 — Contains a list of IDs to find the ID of the parent.
