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: )
