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.
European.ldif
Example.ldif
Example-roles.ldif
Example-views.ldif
Example 4.3. LDIF Directory Contents
• European.ldif — Contains European character samples.
• Example.ldif — Is a sample LDIF file.
• Example-roles.ldif — Is a sample LDIF file similar to Example.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.
exports/ imports/ server/
Example 4.4. Lock Directory Contents
The lock mechanisms stored in the exports, imports, 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. They 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:
Lock table is out of available locks), double the value of the nsslapd-db-locks
attribute in the cn=config,cn=ldbm database,cn=plugins,cn=config entry.
For example, if the current value is 10000, set it to 20000. If the problem persists, double the
number again. To monitor the current and maximum number of locks, do a search on cn=database,
cn=monitor, cn=ldbm database, cn=plugins, cn=config. For example:
ldapsearch -h localhost -p 389 -D "cn=directory manager" -w password
-b "cn=database,cn=monitor,cn=ldbm database, cn=plugins,cn=config" objectclass=* | grep
-- -locks: )
