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.

4.5. LDIF Files

Sample LDIF files are stored in the /var/lib/dirsrv/slapd-instance_name/ldif directory for

storing LDIF-related files. Example 4.3, “LDIF Directory Contents” lists the /ldif directory contents.

Exa mple 4 .3. LDIF Directory Contents

European.ldif

Example.ldif

Example-roles.ldif

Example-views.ldif

European.ldif — Contains European character samples.

Exam ple.ldif — Is a sample LDIF file.

Exam ple-roles.ldif — Is a sample LDIF file similar to Exam ple.ldif, except that it uses roles

and class of service instead of groups for setting access control and resource limits for directory

administrators.

NOTE

The LDIF files exported by db2ldif or db2ldif.pl scripts in the instance directory are stored

in /var/lib/dirsrv/slapd-instance_name/ldif.

4.6. Lock Files

Each Directory Server instance contains a /var/lock/dirsrv/slapd-instance_name directory for

storing lock-related files. The following is a sample listing of the locks directory contents.

Exa mple 4 .4 . Lock Directory Contents

exports/ im ports/ server/

The lock mechanisms stored in the exports, im ports, and server subdirectories prevent multiple,

simultaneous operations from conflicting with each other. The lock mechanisms allow for one server

instance to run at a time, with possible multiple export jobs. T hey also permit one ldif2db import

operation at a time (not ldif2db.pl, because multiple ldif2db.pl operations can be run at any

time) to the exclusion of all export and slapd server operations.

If there are error messages indicating that the lock table is out of available locks (for example, libdb:
