#
# Firebird version 4.0 configuration file
#
# Comments
# --------
# The # character is used for comments and can be placed anywhere on a
# line.  Anything following the # character on a line is considered a
# comment.
#
# Examples:
#
#    # This is a comment
#    DefaultDbCachePages = 2048   # This is an end-of-line comment
#
# Entries
# -------
# The default value for each entry is listed to the right of the "=".
# To activate an entry, remove the leading "#"s and supply the desired
# value.
#
# Please note, by default a number of the values are specified in **Bytes** (Not KB).
# You may add obvious abbreviations k, m and g in the end of a number to specify
# kilobytes, megabytes and gigabytes.
#
# There are three types of configuration values: integer, boolean and string.
#
# Integer
# -------
# Integers is what they sound like, an integral value. Examples:
#   1
#   42
#   4711
#   24M		# 24 * 1024 * 1024
#
# Boolean
# -------
# Boolean is expressed as integer values with 0 (zero) being "false" and
# non-zero is taken to mean "true". For consistency we recommend you
# only use 0/1. Also strings 'y', 'yes' and 'true' stand for "true".
#
# String
# ------
# Strings are also what they sound like, strings. Examples:
#   RemoteServiceName = gds_db
#   RemotePipeName = pipe47
#
# Scopes
# ------
# Some parameters are marked as per-database / per-connection configurable.
# Per-database configuration is done in file databases.conf (former aliases.conf).
# Per-connection configuration is primarily client tool and done using
# isc_dpb_config parameter in DPB (isc_spb_config for services).
# Configuration data, added to parameters block, has same format as this file.
# Pay attention that since firebird3 there is no hard limit of 255 bytes per entry
# provided you are using isc_dpb_version2 format of DPB. The simplest way to create
# DPB/SPB is to use IXpbBuilder - when needed you will have >255 bytes entries in
# parameters block. Notice that per-database entries also may be tuned using DPB
# in case of embedded engine when attaching to database first time.
#
# Macro substitution
# ------------------
# There is a number of predefined macro commands, that can be used in config
# files where directory name is needed. They are available using $(name) syntax.
# The complete list of them as follows:
#	root - root directory of firebird instance
#	install - directory where firebird is installed
#	this - directory where current configuration file is located
#	dir_conf - directory where firebird.conf and databases.conf are located
#	dir_secDb - directory where default security database is located
#	dir_plugins - directory where plugins are located
#	dir_udf - directory where UDFs are located by default
#	dir_sample - directory where samples are located
#	dir_sampleDb - directory where sample DB (employee.fdb) is located
#	dir_intl - directory where international modules are located
#	dir_msg - directory where messages file (firebird.msg) is located
# Like the rest of config internals macros are case-insensitive.
# Capital letters here are used only for better human readability.
#
#
# Includes
# --------
# One can include one config file into another one.
# When relative path is used, it's treated relative to current config file.
# I.e. when
#	include some_file.conf
# is used in /opt/config/master.conf, we include /opt/config/some_file.conf.
# Traditional wildcards * and ? may be used in include operator. In this case
# all matching files will be included in undefined order. Example:
#	include $(dir_plugins)/config/*.conf
#
# Portions of this file have been reproduced/made available with the

# Database Paths/Directories
#
# DatabaseAccess may be None, Full or Restrict. If you choose Restrict,
# provide ';'-separated trees list, where database files are stored.
# Relative paths are treated relative to the root directory of firebird.
# Default value 'Full' gives full access to all files on your site.
# To specify access to specific trees, enum all required paths
# (for Windows this may be something like 'C:\DataBase;D:\Mirror',
# for unix - '/db;/mnt/mirrordb'). If you choose 'None', then only
# databases listed in databases.conf can be attached.
#
# Note: simple quotation marks shown above should *NOT* be used when
# specifying values and directory path names. Examples:

# Ability to access databases remotely
#
# RemoteAccess may be true or false (1/0, Yes/No) - it's boolean value.
# By default RemoteAccess to all databases except security DB is enabled.
# If you plan to use more than one dedicated security database it's
# recommended to disable remote access to them in databases.conf.

# ----------------------------
# External File Paths/Directories
#
# ExternalFileAccess may be None, Full or Restrict. If you choose
# Restrict, provide ';'-separated trees list, where external files
# are stored. Relative paths are treated relative to the root directory
# of firebird. Default value 'None' disables any use of external files
# on your site. To specify access to specific trees, enum all required
# paths (for Windows this may be something like 'C:\ExternalTables',
# for unix - '/db/extern;/mnt/extern').
#
# Per-database configurable.

#
# Since FB4.0 default value is None. Set it to 'Restrict UDF' to have
# the same restrictions as in previous FB versions. To specify access
# to specific trees, enum all required paths (for Windows this may be

# ----------------------------
# Temporary directories
#
# Provide ';'-separated trees list, where temporary files are stored.
# Relative paths are treated relative to the root directory of firebird.
# Default value is determined using FIREBIRD_TMP, TEMP or TMP
# environment options. Once the first specified directory has no

#
# Type: integer
#
#MaxUserTraceLogSize = 10


# ----------------------------
# Number of cached database pages
#
# This sets the number of pages from any one database that can be held
# in cache at once. If you increase this value, the engine will
# allocate more pages to the cache for every database. By default, the
# SuperServer allocates 2048 pages for each database and the classic
# allocates 256 pages per client connection per database.
#
# Per-database configurable.
#
# Type: integer
#
#DefaultDbCachePages = 2048

# ----------------------------
# Disk space preallocation
#
# Sets the amount of preallocated disk space in bytes. Disk space
# preallocation allows to reduce physical file fragmentation and to make
# database work in out of disk space condition. With preallocation enabled,
# engine allocates 1/16nth of already allocated disk space at a time but
# not less than 128KB and no more than DatabaseGrowthIncrement (128MB by
# default). To disable preallocation set DatabaseGrowthIncrement to zero.

#
# Type: boolean

# Per-database configurable.
#
#UseFileSystemCache = true

# ----------------------------
# File system cache threshold
#
# The threshold value that determines whether Firebird will use file system
# cache or not. File system caching is used if database cache size in pages
# (configured explicitly in database header or via DefaultDbCachePages setting)
# is less than FileSystemCacheThreshold value.
#
# To use file system cache always set FileSystemCacheThreshold to a large value.
# To bypass file system cache for all databases set FileSystemCacheThreshold to
# zero.
#
# CAUTION!
# This setting is deprecated and will be removed in future Firebird versions.
# Consider using "UseFileSystemCache" setting instead.
# If "UseFileSystemCache" is set, then value of "FileSystemCacheThreshold" is
# ignored.
# If "UseFileSystemCache" is not set, and "FileSystemCacheThreshold" is set
# then value of "FileSystemCacheThreshold" is in use and accounted by the
# engine.
#
# Type: integer, measured in database pages
#
# Per-database configurable.
#
#FileSystemCacheThreshold = 64K

# ----------------------------
# File system cache size
#
# This setting controls the maximum amount of RAM used by Windows file system
# cache on 64-bit Windows XP, Windows Server 2003 SP1 or later host. It has no
# effect for Unix hosts in this release yet.
#
# Note that the lowest number presently supported is 10%, and the highest number
# is 95%; numbers outside these limits will be set to the default of 30%.
#
# If the cache size has already been selected when the engine starts the host
# setting will not be changed. Thus you may need to reboot the host for the
# change of this setting to have effect.
#
# To leave host caching settings unchanged set this parameter to 0. This is
# the default parameter value.
#
# Security note
# To adjust the setting engine needs SeIncreaseQuotaPrivilege right. Built-in
# service accounts and administrators have it by default. Installer grants this
# right to Firebird service account. If the engine fails to adjust the cache
# size setting it will log warning message to the firebird.log and continue.
#
# Type: integer, measured in % of total physical RAM
#
#FileSystemCacheSize = 0

# ----------------------------
# Remove protection against opening databases on NFS mounted volumes on
# Linux/Unix and SMB/CIFS volumes on Windows.
#
# This also permits creating database shadows on mounted network volumes.
#
#     ***WARNING*** ***WARNING*** ***WARNING*** ***WARNING***
#
# This option removes an important safety feature of Firebird and can
# cause irrecoverable database corruption. Do not use this option unless
# you understand the risks and are prepared to accept the loss of the
# contents of your database.
# Unless this configuration option is changed from 0 to 1, Firebird can
# open a database only if the database is stored on a drive physically
# attached to the local computer - the computer running that copy of
# Firebird. Requests for connections to databases stored on NFS mounted
# drives are redirected to a Firebird server running on the computer that
# "owns" the disk.
# This restriction prevents two different copies of Firebird from opening
# the same database without coordinating their activities. Uncoordinated
# access by multiple copies of Firebird will corrupt a database. On a local
# system, the system-level file locking prevents uncoordinated access to
# the database file.
#
# NFS does not provide a reliable way to detect multiple users of a file on
# an NFS mounted disk. If a second copy of Firebird connects to a database on
# an NFS mounted disk, it will corrupt the database.
# Under some circumstances, running a Firebird server on the computer that
# owns NFS mounted volumes is inconvenient or impossible. Applications that
# use the "embedded" variant of Firebird and never share access to a database
# can use this option to permit direct access to databases on NFS mounted
# volumes.
#
# The situation for SMB/CIFS is quite similar to NFS with not all configurations
# providing file locking mechanisms needed for safe operation. Using SuperServer
# engine with the database on NT file server may be considered relatively safe
# as file locking protects the database from being used by the several engines.
# Network stack can still change order of writes so you may get a corrupted
# database in case of network errors or power outage.
#
# The useful and safe case is working with a shared database marked read-only.
#
# DO NOT ENABLE THIS OPTION UNLESS YOU REALLY KNOW WHAT YOU ARE DOING.

# Temporary space management
#
# Temporary storage is used by the sorting module, it's also

# This value reflects the allocation granularity.
#
# Type: integer
#
#TempBlockSize = 1M

#
# The maximum amount of the temporary space that can be cached

#
# For Classic servers, this setting is defaulted to 8 MB.

#TempCacheLimit = 64M

# ----------------------------
# Maximum allowed identifier name length in bytes
#
# Sets a limit for the number of bytes in an identifier.

# or refetch them from data pages after the sorting.
#
# Defines the maximum sort record size (in bytes) that can be stored inline,

# This group of parameters determines what plugins will be used by firebird.
# Format of string is the list of plugins, separated by space, ',' or ';'.
# Plugins will be tried in an order, specified here.
# In many cases correct order is important!
#
# Type: string

# AuthServer and AuthClient determine which authentication methods will be used
# by network server and client redirector. The Secure remote password plugin
# using SHA-256 for the client proof is the default for both client and Server.
# Additionally, the default client configuration (AuthClient) also supports old Srp
# plugin using SHA-1 for the client proof. This enables backwards compatibility
# with old Firebird 3 servers but does not comply with NIST security requirements.
# Srp plugins using other SHA algorithms (SHA-224, SHA-384 & SHA-512) are also
# implemented and may be used (names are Srp224, Srp384 & Srp512 respectively).
#
# The default client configuration (AuthClient) also supports the pre-Firebird 3 legacy
# authentication protocol (Legacy_Auth). This is again for backwards
# compatibility but has many known weaknesses and is deprecated for current use.
#
# The default Windows client configuration (AuthClient) also includes support for
# the Win_Sspi plugin. This implements windows trusted authentication and is backward
# compatible with 2.1 and 2.5 clients and servers running on Windows.

#
# If you need to use server plugins that do not provide encryption key (Legacy_Auth is the
# only such std plugin) you should also turn off required encryption on the wire with WireCrypt
# configuration parameter except when working with the XNET protocol which is never encrypted.
#

# UserManager sets plugin used to work with security database. If more than
# one plugin is given, first plugin from the list is used by default. If you
# need to manage legacy logins using legacy tools set it to Legacy_UserManager.
# Other managers may be chosen in create/alter/drop user commands.
#
# Per-database configurable.
#
#UserManager = Srp

# TracePlugin is used by firebird trace facility to send trace data to the user
# or log file in audit case.
#
#TracePlugin = fbtrace

# Wire crypt plugins are used to crypt data transferred over the wire.
# In default case wire is encrypted using ChaCha#20 or Alleged RC4.
# Key must be generated by auth plugin.
# For chacha we are using 16 or 32 bytes key (depends upon what is provided
# by auth plugin), 12 bytes nonce and 4 bytes counter, 20 (10 + 10) rounds are made.

# ----------------------------
#
# Ability to use encrypted security database
#
# If one relies on network encryption feature with crypt key generated
# by authentication plugin (like SRP does) to transfer database crypt
# keys over the wire then use of encrypted security databases is a kind of
# vicious circle. In order to send DB crypt key over the wire in secure way
# wire transfers should be already encrypted but this requires wire crypt key
# from authentication plugin which needs to open security database for hash
# validation which in turn requires DB crypt key. Luckily in most cases there
# is no big need to encrypt security database - it protects itself quite well
# if you use high quality passwords. But in some cases it's desired to have
# security database encrypted, for example if one wants to use self security
# database feature for encrypted database. In that case special care should be
# taken to encrypt that key before passing it to server using callback. Make
# sure your keys are well encrypted before enabling this parameter. Take into
# account that with AllowEncryptedSecurityDatabase=TRUE unencrypted by firebird
# protocol key transfer may take place even with not encrypted security database.
# This feature is not supported by legacy authentication plugin - if you care
# about security please never use legacy authentication.

# Which CPUs should be used (Windows Only)
#
# In an SMP system, sets which processors can be used by the server.
# The value is taken from a bit map in which each bit represents a CPU.
# Thus, to use only the first processor, the value is 1. To use both

# Remove protection against redirecting requests to other servers

#     ***WARNING*** ***WARNING*** ***WARNING*** ***WARNING***
#
# Ability to redirect requests to other servers was initially present
# in Interbase, but was broken by Borland in Interbase 6.0, when
# they added SQL dialects. Request redirection was fixed in firebird 2.0,
# but today such behaviour (proxy) seems to be dangerous from security
# point of view. Imagine, you have one carefully protected firebird server,
# access to which is possible from global net. But in case when this server
# has access to your internal LAN (may and should be restricted,
# but often possible), it will work as a gateway for incoming requests like:
# firebird.your.domain.com:internal_server:/private/database.fdb
# It's enough to know name/IP of some internal server on your LAN, and for
# this connection one even need not know login/password on external server.
# Such gateway easily overrides firewall, installed to protect your LAN
# from outside attack.

# DO NOT ENABLE THIS OPTION UNLESS YOU REALLY KNOW WHAT YOU ARE DOING.
