and how much of that change an administrator might be willing to lose in a

-
-Berkeley DB produces transaction logs that can be used to reconstruct

-lose one hour's worth of changes, they could take down the server in

-H2: Berkeley DB Logs
-
-Berkeley DB log files grow, and the administrator has to deal with it. The
-procedure is known as log file archival or log file rotation.
-
-Note: The actual log file rotation is handled by the Berkeley DB engine.
-
-Logs of current transactions need to be stored into files so that the database
-can be recovered in the event of an application crash. Administrators can change
-the size limit of a single log file (by default 10MB), and have old log files
-removed automatically, by setting up DB environment (see below). The reason
-Berkeley DB never deletes any log files by default is that the administrator
-may wish to backup the log files before removal to make database recovery
-possible even after a catastrophic failure, such as file system corruption.
-
-Log file names are {{F:log.XXXXXXXXXX}} (X is a digit). By default the log files
-are located in the BDB backend directory. The {{F:db_archive}} tool knows what
-log files are used in current transactions, and what are not. Administrators can
-move unused log files to a backup media, and delete them. To have them removed
-automatically, place set_flags {{DB_LOG_AUTOREMOVE}} directive in {{F:DB_CONFIG}}.
-
-Note: If the log files are removed automatically, recovery after a catastrophic
-failure is likely to be impossible.
-
-The files with names {{F:__db.001}}, {{F:__db.002}}, etc are just shared memory
-regions (or whatever). These ARE NOT 'logs', they must be left alone. Don't be
-afraid of them, they do not grow like logs do.
-
-To understand the {{F:db_archive}} interface, the reader should refer to
-chapter 9 of the Berkeley DB guide. In particular, the following chapters are
-recommended:
-
-* Database and log file archival - {{URL:http://www.oracle.com/technology/documentation/berkeley-db/db/ref/transapp/archival.html}}
-* Log file removal - {{URL:http://www.oracle.com/technology/documentation/berkeley-db/db/ref/transapp/logfile.html}}
-* Recovery procedures - {{URL:http://www.oracle.com/technology/documentation/berkeley-db/db/ref/transapp/recovery.html}}
-* Hot failover - {{URL:http://www.oracle.com/technology/documentation/berkeley-db/db/ref/transapp/hotfail.html}}
-* Complete list of Berkeley DB flags - {{URL:http://www.oracle.com/technology/documentation/berkeley-db/db/api_c/env_set_flags.html}}
-
-Advanced installations can use special environment settings to fine-tune some
-Berkeley DB options (change the log file limit, etc). This can be done by using
-the {{F:DB_CONFIG}} file. This magic file can be created in BDB backend directory
-set up by {{slapd.conf}}(5). More information on this file can be found in File
-naming chapter. Specific directives can be found in C Interface, look for
-{{DB_ENV->set_XXXX}} calls.
-
-Note: options set in {{F:DB_CONFIG}} file override options set by OpenLDAP.
-Use them with extreme caution. Do not use them unless You know what You are doing.
-
-The advantages of {{F:DB_CONFIG}} usage can be the following:
-
-* to keep data files and log files on different mediums (i.e. disks) to improve
- performance and/or reliability;
-* to fine-tune some specific options (such as shared memory region sizes);
-* to set the log file limit (please read Log file limits before doing this).
-
-To figure out the best-practice BDB backup scenario, the reader is highly
-recommended to read the whole Chapter 9: Berkeley DB Transactional Data Store Applications.
-This chapter is a set of small pages with examples in C language. Non-programming
-people can skip these examples without loss of knowledge.

+This directive specifies the indices to maintain for the given

+common types of matches that may be used in an LDAP search filter.
+
+\Example:
+
+> index: default pres,eq
+> index: uid
+> index: cn,sn pres,eq,sub
+> index: objectClass eq
+
+The first line sets the default set of indices to maintain to
+present and equality. The second line causes the default (pres,eq)
+set of indices to be maintained for the {{EX:uid}} attribute type.
+The third line causes present, equality, and substring indices to
+be maintained for {{EX:cn}} and {{EX:sn}} attribute types. The
+fourth line causes an equality index for the {{EX:objectClass}}
+attribute type.
+
+There is no index keyword for inequality matches. Generally these
+matches do not use an index. However, some attributes do support
+indexing for inequality matches, based on the equality index.
+
+A substring index can be more explicitly specified as {{EX:subinitial}},
+{{EX:subany}}, or {{EX:subfinal}}, corresponding to the three
+possible components
+of a substring match filter. A subinitial index only indexes
+substrings that appear at the beginning of an attribute value.
+A subfinal index only indexes substrings that appear at the end
+of an attribute value, while subany indexes substrings that occur
+anywhere in a value.
+
+Note that by default, setting an index for an attribute also
+affects every subtype of that attribute. E.g., setting an equality
+index on the {{EX:name}} attribute causes {{EX:cn}}, {{EX:sn}}, and every other
+attribute that inherits from {{EX:name}} to be indexed.
+

+presence searches on the attribute occur very frequently during
+normal use of the directory. Most applications don't use presence
+searches, so usually presence indexing is not very useful.

+H4: maxreaders: <integer>
+
+This directive specifies the maximum number of threads that may have
+concurrent read access to the database. Tools such as slapcat count as a
+single thread, in addition to threads in any active slapd processes. The
+default is 126.
+
+
+H4: maxsize: <bytes>
+
+This directive specifies the maximum size of the database in bytes. A memory
+map of this size is allocated at startup time and the database will not be
+allowed to grow beyond this size. The default is 10485760 bytes (10MB). This
+setting may be changed upward if the configured limit needs to be increased.
+
+Note: It is important to set this to as large a value as possible, (relative
+to anticipated growth of the actual data over time) since growing the size
+later may not be practical when the system is under heavy load.

+
+H4: mode: { <octal> | <symbolic> }

+
+
+H4: rtxnsize: <entries>
+
+This directive specifies the maximum number of entries to process in a single
+read transaction when executing a large search. Long-lived read transactions
+prevent old database pages from being reused in write transactions, and so
+can cause significant growth of the database file when there is heavy write
+traffic. This setting causes the read transaction in large searches to be
+released and reacquired after the given number of entries has been read, to
+give writers the opportunity to reclaim old database pages. The default is
+10000.
+
+
+H4: searchstack: <integer>
+
+Specify the depth of the stack used for search filter evaluation.
+Search filters are evaluated on a stack to accommodate nested {{EX:AND}} /
+{{EX:OR}} clauses. An individual stack is allocated for each server thread.
+The depth of the stack determines how complex a filter can be evaluated
+without requiring any additional memory allocation. Filters that are
+nested deeper than the search stack depth will cause a separate stack to
+be allocated for that particular search operation. These separate allocations
+can have a major negative impact on server performance, but specifying
+too much stack will also consume a great deal of memory. Each search
+uses 512K bytes per level on a 32-bit machine, or 1024K bytes per level
+on a 64-bit machine. The default stack depth is 16, thus 8MB or 16MB
+per thread is used on 32 and 64 bit machines, respectively. Also the
+512KB size of a single stack slot is set by a compile-time constant which
+may be changed if needed; the code must be recompiled for the change
+to take effect.

-H2: Caching
-
-We all know what caching is, don't we?
-
-In brief, "A cache is a block of memory for temporary storage of data likely
-to be used again" - {{URL:http://en.wikipedia.org/wiki/Cache}}
-
-There are 3 types of caches, BerkeleyDB's own cache, {{slapd}}(8)
-entry cache and {{TERM:IDL}} (IDL) cache.
-
-
-H3: Berkeley DB Cache
-
-There are two ways to tune for the BDB cachesize:
-
-(a) BDB cache size necessary to load the database via slapadd in optimal time
-
-(b) BDB cache size necessary to have a high performing running slapd once the data is loaded
-
-For (a), the optimal cachesize is the size of the entire database. If you
-already have the database loaded, this is simply a
-
-> du -c -h *.bdb
-
-in the directory containing the OpenLDAP ({{/usr/local/var/openldap-data}}) data.
-
-For (b), the optimal cachesize is just the size of the {{id2entry.bdb}} file,
-plus about 10% for growth.
-
-The tuning of {{DB_CONFIG}} should be done for each BDB type database
-instantiated (back-bdb, back-hdb).
-
-Note that while the {{TERM:BDB}} cache is just raw chunks of memory and
-configured as a memory size, the {{slapd}}(8) entry cache holds parsed entries,
-and the size of each entry is variable.
-
-There is also an IDL cache which is used for Index Data Lookups.
-If you can fit all of your database into slapd's entry cache, and all of your
-index lookups fit in the IDL cache, that will provide the maximum throughput.
-
-If not, but you can fit the entire database into the BDB cache, then you
-should do that and shrink the slapd entry cache as appropriate.
-
-Failing that, you should balance the BDB cache against the entry cache.
-
-It is worth noting that it is not absolutely necessary to configure a BerkeleyDB
-cache equal in size to your entire database. All that you need is a cache
-that's large enough for your "working set."
-
-That means, large enough to hold all of the most frequently accessed data,
-plus a few less-frequently accessed items.
-
-For more information, please see: {{URL:http://www.oracle.com/technology/documentation/berkeley-db/db/ref/am_conf/cachesize.html}}
-
-H4: Calculating Cachesize
-
-The back-bdb database lives in two main files, {{F:dn2id.bdb}} and {{F:id2entry.bdb}}.
-These are B-tree databases. We have never documented the back-bdb internal
-layout before, because it didn't seem like something anyone should have to worry
-about, nor was it necessarily cast in stone. But here's how it works today,
-in OpenLDAP 2.4.
-
-A B-tree is a balanced tree; it stores data in its leaf nodes and bookkeeping
-data in its interior nodes (If you don't know what tree data structures look
- like in general, Google for some references, because that's getting far too
-elementary for the purposes of this discussion).
-
-For decent performance, you need enough cache memory to contain all the nodes
-along the path from the root of the tree down to the particular data item
-you're accessing. That's enough cache for a single search. For the general case,
-you want enough cache to contain all the internal nodes in the database.
-
-> db_stat -d
-
-will tell you how many internal pages are present in a database. You should
-check this number for both dn2id and id2entry.
-
-Also note that {{id2entry}} always uses 16KB per "page", while {{dn2id}} uses whatever
-the underlying filesystem uses, typically 4 or 8KB. To avoid thrashing,
-your cache must be at least as large as the number of internal pages in both
-the {{dn2id}} and {{id2entry}} databases, plus some extra space to accommodate
-the actual leaf data pages.
-
-For example, in my OpenLDAP 2.4 test database, I have an input LDIF file that's
-about 360MB. With the back-hdb backend this creates a {{dn2id.bdb}} that's 68MB,
-and an {{id2entry}} that's 800MB. db_stat tells me that {{dn2id}} uses 4KB pages, has
-433 internal pages, and 6378 leaf pages. The id2entry uses 16KB pages, has 52
-internal pages, and 45912 leaf pages. In order to efficiently retrieve any
-single entry in this database, the cache should be at least
-
-> (433+1) * 4KB + (52+1) * 16KB in size: 1736KB + 848KB =~ 2.5MB.
-
-This doesn't take into account other library overhead, so this is even lower
-than the barest minimum. The default cache size, when nothing is configured,
-is only 256KB.
-
-This 2.5MB number also doesn't take indexing into account. Each indexed
-attribute results in another database file. Earlier versions of OpenLDAP
-kept these index databases in Hash format, but from OpenLDAP 2.2 onward
-the index databases are in B-tree format so the same procedure can
-be used to calculate the necessary amount of cache for each index database.
-
-For example, if your only index is for the objectClass attribute and db_stat
-reveals that {{objectClass.bdb}} has 339 internal pages and uses 4096 byte
-pages, the additional cache needed for just this attribute index is
-
-> (339+1) * 4KB =~ 1.3MB.
-
-With only this index enabled, I'd figure at least a 4MB cache for this backend.
-(Of course you're using a single cache shared among all of the database files,
-so the cache pages will most likely get used for something other than what you
-accounted for, but this gives you a fighting chance.)
-
-With this 4MB cache I can slapcat this entire database on my 1.3GHz PIII in
-1 minute, 40 seconds. With the cache doubled to 8MB, it still takes the same 1:40s.
-Once you've got enough cache to fit the B-tree internal pages, increasing it
-further won't have any effect until the cache really is large enough to hold
-100% of the data pages. I don't have enough free RAM to hold all the 800MB
-id2entry data, so 4MB is good enough.
-
-With back-bdb and back-hdb you can use "db_stat -m" to check how well the
-database cache is performing.
-

-
-H3: {{slapd}}(8) Entry Cache (cachesize)
-
-The {{slapd}}(8) entry cache operates on decoded entries. The rationale - entries
-in the entry cache can be used directly, giving the fastest response. If an entry
-isn't in the entry cache but can be extracted from the BDB page cache, that will
-avoid an I/O but it will still require parsing, so this will be slower.
-
-If the entry is in neither cache then BDB will have to flush some of its current
-cached pages and bring in the needed pages, resulting in a couple of expensive
-I/Os as well as parsing.
-
-The most optimal value is of course, the entire number of entries in the database.
-However, most directory servers don't consistently serve out their entire database, so setting this to a lesser number that more closely matches the believed working set of data is
-sufficient. This is the second most important parameter for the DB.
-
-As far as balancing the entry cache vs the BDB cache - parsed entries in memory
-are generally about twice as large as they are on disk.
-
-As we have already mentioned, not having a proper database cache size will
-cause performance issues. These issues are not an indication of corruption
-occurring in the database. It is merely the fact that the cache is thrashing
-itself that causes performance/response time to slowdown.
-
-
-H3: {{TERM:IDL}} Cache (idlcachesize)
-
-Each IDL holds the search results from a given query, so the IDL cache will
-end up holding the most frequently requested search results. For back-bdb,
-it is generally recommended to match the "cachesize" setting. For back-hdb,
-it is generally recommended to be 3x"cachesize".
-
-{NOTE: The idlcachesize setting directly affects search performance}

-.SH NAME
-slapd\-bdb, slapd\-hdb \- Berkeley DB backends to slapd
-.SH SYNOPSIS
-.B ETCDIR/slapd.conf
-.SH DESCRIPTION
-The \fBbdb\fP backend to
-.BR slapd (8)
-uses the Oracle Berkeley DB (BDB) package to store data.
-It makes extensive use of indexing and caching to speed data access.
-.LP
-Note that BDB is deprecated and support will be dropped in future
-OpenLDAP releases. Installations should use the \fBmdb\fP
-backend instead.
-.LP
-\fBhdb\fP is a variant of
-the \fBbdb\fP backend that uses a hierarchical database layout which
-supports subtree renames. It is both more space-efficient and more
-execution-efficient than the \fBbdb\fP backend. It is otherwise identical
-to the \fBbdb\fP behavior, and all the same configuration options apply.
-.LP
-It is noted that these options are intended to complement
-Berkeley DB configuration options set in the environment's
-.B DB_CONFIG
-file. See Berkeley DB documentation for details on
-.B DB_CONFIG
-configuration options.
-Where there is overlap, settings in
-.B DB_CONFIG
-take precedence.
-.SH CONFIGURATION
-These
-.B slapd.conf
-options apply to the \fBbdb\fP and \fBhdb\fP backend database.
-That is, they must follow a "database bdb" or "database hdb" line and
-come before any subsequent "backend" or "database" lines.
-Other database options are described in the
-.BR slapd.conf (5)
-manual page.
-.TP
-.BI cachesize \ <integer>
-Specify the size in entries of the in-memory entry cache maintained
-by the \fBbdb\fP or \fBhdb\fP backend database instance.
-The default is 1000 entries.
-.TP
-.BI cachefree \ <integer>
-Specify the number of entries to free from the entry cache when the
-cache reaches the \fBcachesize\fP limit.
-The default is 1 entry.
-.TP
-.BI checkpoint \ <kbyte>\ <min>
-Specify the frequency for checkpointing the database transaction log.
-A checkpoint operation flushes the database buffers to disk and writes
-a checkpoint record in the log.
-The checkpoint will occur if either \fI<kbyte>\fP data has been written or
-\fI<min>\fP minutes have passed since the last checkpoint.
-Both arguments default to zero, in which case they are ignored. When
-the \fI<min>\fP argument is non-zero, an internal task will run every
-\fI<min>\fP minutes to perform the checkpoint.
-See the Berkeley DB reference guide for more details.
-.TP
-.B checksum
-Enable checksum validation of DB pages whenever they are read from disk.
-This setting can only be configured before any database files are created.
-.TP
-.BI cryptfile \ <file>
-Specify the pathname of a file containing an encryption key to use for
-encrypting the database. Encryption is performed using Berkeley DB's
-implementation of AES. Note that encryption can only be configured before
-any database files are created, and changing the key can only be done
-after destroying the current database and recreating it. Encryption is
-not enabled by default, and some distributions of Berkeley DB do not
-support encryption.
-.TP
-.BI cryptkey \ <key>
-Specify an encryption key to use for encrypting the database. This option
-may be used when a separate
-.I cryptfile
-is not desired. Only one of
-.B cryptkey
-or
-.B cryptfile
-may be configured.
-.TP
-.BI dbconfig \ <Berkeley-DB-setting>
-Specify a configuration directive to be placed in the
-.B DB_CONFIG
-file of the database directory. The
-.B dbconfig
-directive is just a convenience
-to allow all necessary configuration to be set in the
-.B slapd.conf
-file.
-The options set using this directive will only be written to the
-.B DB_CONFIG
-file if no such file existed at server startup time, otherwise
-they are completely ignored. This allows one
-to set initial values without overwriting/destroying a
-.B DB_CONFIG
-file that was already customized through other means.
-This directive may be specified multiple times, as needed.
-For example:
-.RS
-.nf
- dbconfig set_cachesize 0 1048576 0
- dbconfig set_lg_bsize 2097152
-.fi
-.RE
-.TP
-.B dbnosync
-Specify that on-disk database contents should not be immediately
-synchronized with in memory changes.
-Enabling this option may improve performance at the expense of data
-security.
-See the Berkeley DB reference guide for more details.
-.TP
-\fBdbpagesize \fR \fI<dbfile> <size>\fR
-Specify the page size to use for a particular database file, in units
-of 1024 bytes. The default for the
-.B id2entry
-file is 16, the default for all other files depends on the size of the
-underlying filesystem's block size (typically 4 or 8).
-The maximum that BerkeleyDB supports is 64. This
-setting usually should not need to be changed, but if BerkeleyDB's
-"db_stat \-d" shows a large amount of overflow pages in use in a file,
-setting a larger size may increase performance at the expense of
-data integrity. This setting only takes effect when a database is
-being newly created. See the Berkeley DB reference guide for more details.
-.TP
-.BI directory \ <directory>
-Specify the directory where the BDB files containing this database and
-associated indexes live.
-A separate directory must be specified for each database.
-The default is
-.BR LOCALSTATEDIR/openldap\-data .
-.TP
-.B dirtyread
-Allow reads of modified but not yet committed data.
-Usually transactions are isolated to prevent other operations from
-accessing uncommitted data.
-This option may improve performance, but may also return inconsistent
-results if the data comes from a transaction that is later aborted.
-In this case, the modified data is discarded and a subsequent search
-will return a different result.
-.TP
-.BI dncachesize \ <integer>
-Specify the maximum number of DNs in the in-memory DN cache.
-Ideally this cache should be
-large enough to contain the DNs of every entry in the database. If
-set to a smaller value than the \fBcachesize\fP it will be silently
-increased to equal the \fBcachesize\fP. The default value is 0 which
-means unlimited, i.e. the DN cache will grow without bound.
-
-It should be noted that the \fBDN cache\fP is allowed to temporarily
-grow beyond the configured size. It does this if many entries are
-locked when it tries to do a purge, because that means they're
-legitimately in use. Also, the \fBDN cache\fP never purges entries
-that have cached children, so depending on the shape of the DIT, it
-could have lots of cached DNs over the defined limit.
-.TP
-.BI idlcachesize \ <integer>
-Specify the size of the in-memory index cache, in index slots. The
-default is zero. A larger value will speed up frequent searches of
-indexed entries. An \fBhdb\fP database needs a large \fBidlcachesize\fP
-for good search performance, typically three times the
-.B cachesize
-(entry cache size)
-or larger.
-.TP
-\fBindex \fR{\fI<attrlist>\fR|\fBdefault\fR} [\fBpres\fR,\fBeq\fR,\fBapprox\fR,\fBsub\fR,\fI<special>\fR]
-Specify the indexes to maintain for the given attribute (or
-list of attributes).
-Some attributes only support a subset of indexes.
-If only an \fI<attr>\fP is given, the indices specified for \fBdefault\fR
-are maintained.
-Note that setting a default does not imply that all attributes will be
-indexed. Also, for best performance, an
-.B eq
-index should always be configured for the
-.B objectClass
-attribute.
-
-A number of special index parameters may be specified.
-The index type
-.B sub
-can be decomposed into
-.BR subinitial ,
-.BR subany ,\ and
-.B subfinal
-indices.
-The special type
-.B nolang
-may be specified to disallow use of this index by language subtypes.
-The special type
-.B nosubtypes
-may be specified to disallow use of this index by named subtypes.
-Note: changing \fBindex\fP settings in
-.BR slapd.conf (5)
-requires rebuilding indices, see
-.BR slapindex (8);
-changing \fBindex\fP settings
-dynamically by LDAPModifying "cn=config" automatically causes rebuilding
-of the indices online in a background task.
-.TP
-.B linearindex
-Tell
-.B slapindex
-to index one attribute at a time. By default, all indexed
-attributes in an entry are processed at the same time. With this option,
-each indexed attribute is processed individually, using multiple passes
-through the entire database. This option improves
-.B slapindex
-performance
-when the database size exceeds the \fBdbcache\fP size. When the \fBdbcache\fP is
-large enough, this option is not needed and will decrease performance.
-Also by default,
-.B slapadd
-performs full indexing and so a separate
-.B slapindex
-run is not needed. With this option,
-.B slapadd
-does no indexing and
-.B slapindex
-must be used.
-.TP
-.BR lockdetect \ { oldest | youngest | fewest | random | default }
-Specify which transaction to abort when a deadlock is detected.
-The default is
-.BR random .
-.TP
-.BI mode \ <integer>
-Specify the file protection mode that newly created database
-index files should have.
-The default is 0600.
-.TP
-.BI searchstack \ <depth>
-Specify the depth of the stack used for search filter evaluation.
-Search filters are evaluated on a stack to accommodate nested AND / OR
-clauses. An individual stack is assigned to each server thread.
-The depth of the stack determines how complex a filter can be
-evaluated without requiring any additional memory allocation. Filters that
-are nested deeper than the search stack depth will cause a separate
-stack to be allocated for that particular search operation. These
-allocations can have a major negative impact on server performance,
-but specifying too much stack will also consume a great deal of memory.
-Each search stack uses 512K bytes per level. The default stack depth
-is 16, thus 8MB per thread is used.
-.TP
-.BI shm_key \ <integer>
-Specify a key for a shared memory BDB environment. By default the
-BDB environment uses memory mapped files. If a non-zero value is
-specified, it will be used as the key to identify a shared memory
-region that will house the environment.
-.SH ACCESS CONTROL
