Chapter 4 Server Instance File Reference

This chapter provides an overview of the files that are specific to an instance of Netscape Directory Server (Directory Server)—the files stored under the serverRoot/slapd-serverID directory. Having an overview of the files and configuration information stored in each instance of Directory Server should help you understand the file changes or absence of file changes which occur in the course of directory activity. It should also help you to detect errors and intrusion, by indicating what kind of changes to expect, and as a result, what changes are considered abnormal.

This chapter contains the following sections:

Overview of Directory Server Files

Directory Server files and command-line scripts are stored under the serverRoot/slapd-serverID directory. The only exception is the migrateInstance6 script which is stored under the serverRoot/bin/slapd/admin/bin directory.

Code Example 4-1 shows the contents of the serverRoot/slapd-serverID directory, where directories are marked with a / and scripts are marked with an *. See Chapter 8 "Command-Line Scripts" for further information on command-line scripts.

Code Example 4-1    Contents of the serverRoot/slapd-serverID directory

./ db2ldif* ns-inactivate.pl*
../ db2ldif.pl* restart-slapd*
bak/ getpwenc* restoreconfig*
bak2db* ldif/ saveconfig*
bak2db.pl* ldif2db* start-slapd*
conf_bk/ ldif2db.pl* stop-slapd*
confbak/ ldif2ldap* suffix2instance*
config/ locks/ tmp/
db/ logs/ vlvindex*
db2bak* monitor*
db2bak.pl* ns-accountstatus.pl*
db2index.pl* ns-activate.pl*

To reflect the directory structure under the serverRoot/slapd-serverID directory, this chapter is divided into the following sections:

Backup Files

Configuration Files

Database Files

ldif Files

Lock Files

Log Files

Each section describes the file type and contents.

Backup Files

Each Directory Server instance contains the following three directories for storing backup related files:

bak - contains a directory dated with the time and date of your database backup, for example 2001_02_13_174524/, which in turn holds your database backup copy.

confbak - is the default directory used by the restoreconfig script and the saveconfig scripts. See Chapter 8 "Command-Line Scripts" for further information on Command-line Scripts.

conf_bk - contains a backup copy of the dse.ldif configuration file from the time of installation.

Configuration Files

Each Directory Server instance contains the following directory for storing configuration files:

config - contains the configuration files as explained in "Server Configuration - Overview" on page 27.

Database Files

Each Directory Server instance contains the db directory for storing all the database files. Code Example 4-2 shows a sample listing of the db directory contents.

Code Example 4-2    Contents of sample db directory

./ __db.002 __db.005 NetscapeRoot/
../ __db.003 DBVERSION userRoot/
__db.001 __db.004 log.0000000017

db.00x files are used internally by the database and should not be moved, deleted, or modified in any way.

log.xxxxxxxxxx files are used to store the transaction logs per database.

DBVERSION - used for storing the version of the database.

NetscapeRoot - this directory stores the o=NetscapeRoot database created by default at Typical installation.

userRoot - this directory stores the user-defined suffix (user-defined databases) created at Typical installation time, for example dc=example,dc=com.

Code Example 4-3 shows a sample listing of the NetscapeRoot directory contents.

Code Example 4-3    Contents of a sample NetscapeRoot subdirectory

./ entrydn.db3 parentid.db3
../ givenName.db3 sn.db3
aci.db3 id2entry.db3 uid.db3
cn.db3 nsUniqueId.db3 uniquemember.db3
DBVERSION numsubordinates.db3
dncomp.db3 objectclass.db3

The NetscapeRoot subdirectories contain an index_name.db3 file for every index currently defined in the database, where index_name is the name of the index. In addition to these index_name.db3 files the Netscape and userRoot subdirectories contain the following files:

dncomp.db3 - contains a list of partial DNs enabling you to find IDs.

entrydn.db3 - contains a list of full DNs enabling you to find IDs.

id2entry.db3 - contains the actual directory database entries. All other database files can be recreated from this one, if necessary.

nsuniqueid.db3 - contains a list of Netscape unique IDs enabling you to find IDs.

objectclass.db3 - contains a list of IDs which have a particular objectclass.

parentid.db3 - contains a list of IDs allowing you to find ID of parent.

ldif Files

Each Directory Server instance contains the ldif directory for storing ldif related files. Code Example 4-4 shows a sample listing of the ldif directory contents.

Code Example 4-4    Contents of a sample ldif directory

../ European.ldif Example.ldif Example-roles.ldif

The following list describes the content of each of the ldif files:

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.

Lock Files

Each Directory Server instance contains a locks directory for storing lock related files. Code Example 4-5 shows a sample listing of the locks directory contents.

Code Example 4-5    Contents of a sample locks directory

./ ../ exports/ imports/ server/

The lock mechanisms stored under the locks subdirectories exports, imports, and server prevent multiple, simultaneous operations conflicting with each other. The lock mechanisms allow for one server instance to run at a time, with possible multiple export jobs. They also permits one ldif2db import operation at a time (not ldif2db.pl since you can run multiple ldif2db.pl operations at any time) to the exclusion of all export and slapd server operations.

Log Files

Each Directory Server instance contains a logs directory for storing log related files. Code Example 4-6 shows a sample listing of the logs directory contents.

Code Example 4-6    Contents of a sample logs directory

./ access.20010126-120123 audit errors.rotationinfo
../ access.20010130-140221 audit.rotationinfo pid
access access.20010201-100122 errors slapd.stats
access.20010124-180611 access.rotationinfo errors.20010124-180607

The following list describes the content of the log related files:

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. This 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.

The pid is the slapd process identifier.
