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=m onitor, 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: )

4.7. Log Files

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

storing log files. T he following is a sample listing of the /logs directory contents.

Exa mple 4 .5. Log Directory Cont ents

access access.20090228-171925 errors

access.20090221-162824 access.rotationinfo errors.20090221-162824

access.20090223-171949 audit errors.rotationinfo

access.20090227-171818 audit.rotationinfo slapd.stats

The content of the access, audit, and error log files is dependent on the log configuration.

The slapd.stats file is a memory-mapped file which cannot be read by an editor. It contains data

collected by the Directory Server SNMP data collection component. T his data is read by the SNMP

subagent in response to SNMP attribute queries and is communicated to the SNMP master agent

responsible for handling Directory Server SNMP requests.

4.8. PID Files

slapd-serverID.pid and slapd-serverID.startpid files are created in the /var/run/dirsrv

directory when the server is up and running. Both files store the server's process ID.

4.9. Tools

Directory Server tools are stored in three directories on Red Hat Enterprise Linux 5 (32-bit):

/usr/bin
