# Firebird 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, a number of the values are specified in **Bytes** (Not KB).
# Accordingly, we have provided some simple conversion tables at the bottom
# of this file.
#
# 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
#
# 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.
#
# String
# ------
# Strings are also what they sound like, strings. Examples:
# RootDirectory = /opt/firebird
# RemotePipeName = pipe47
#

# ==================================
# Settings for all platforms/engines
# ==================================
#
# ----------------------------
# Specify the root directory under which Firebird is installed.
# Can be used to override the OS-specifically determined one.
#
# Type: string
#
#RootDirectory =
# ----------------------------
# 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 RootDirectory entry
# (see above). Default value 'Full' gives full access to all files
# on your site. To specify access to specific trees, enum all required
# paths (for Win32 this may be something like 'C:\DataBase;D:\Mirror',
# for unix - '/db;/mnt/mirrordb'). If you choose 'None', then only
# databases listed in aliases.conf can be attached.
#
# Note: simple quotation marks shown above should *NOT* be used when
# specifying values and directory path names. Examples:
#
# DatabaseAccess = None
# DatabaseAccess = Restrict C:\DataBase
# DatabaseAccess = Restrict C:\DataBase;D:\Mirror
# DatabaseAccess = Restrict /db
# DatabaseAccess = Restrict /db;/mnt/mirrordb
# DatabaseAccess = Full
#
# UNCONTROLLED DATABASE ACCESS MAY COMPROMISE YOUR SYSTEM!
# IT IS STRONGLY RECOMMENDED THAT THIS SETTING BE USED TO LIMIT
# DATABASE LOCATIONS!
#
# Type: string (special format)
#
#DatabaseAccess = Full
# ----------------------------
# 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 RootDirectory entry
# (see above). Default value 'None' disables any use of external files
# on your site. To specify access to specific trees, enum all required
# paths (for Win32 this may be something like 'C:\ExternalTables',
# for unix - '/db/extern;/mnt/extern').
#
# NOTE: THE EXTERNAL TABLE ENGINE FEATURE COULD BE USED TO COMPROMISE
# THE SERVER/HOST AS WELL AS DATABASE SECURITY!!

#
# Type: string (special format)
#
#ExternalFileAccess = None
# ----------------------------
# External Function (UDF) Paths/Directories
#
# UdfAccess may be None, Full or Restrict. If you choose
# Restrict, provide ';'-separated trees list, where UDF libraries
# are stored. Relative paths are treated relative to RootDirectory entry
# (see above). Default value 'Restrict UDF' provides the same restrictions
# as in FB 1.0. To specify access to specific trees, enum all required
# paths (for Win32 this may be something like 'C:\ExternalFunctions',
# for unix - '/db/extern;/mnt/extern').
#
# NOTE: THE EXTERNAL FUNCTION ENGINE FEATURE COULD BE USED TO COMPROMISE

# IT IS STRONGLY RECOMMENDED THAT THIS SETTING BE USED TO LIMIT
# EXTERNAL FUNCTION LOCATIONS!
#
# Type: string (special format)
#
#UdfAccess = Restrict UDF
# ----------------------------
# Temporary directories
#
# Provide ';'-separated trees list, where temporary files are stored.
# Relative paths are treated relative to RootDirectory entry
# (see above). Default value is determined using FIREBIRD_TMP,
# TEMP or TMP environment options. Once the first specified
# directory has no available space, the engine will switch to the
# next one, and so on.
#
# E.g.:
# TempDirectories = c:\temp
# or
# TempDirectories = c:\temp;d:\temp
#
# Type: string (special format)
#
#这里有改动
TempDirectories = e:\Temp
# ----------------------------
# Legacy hash makes possible use of old security.fdb
# after running misc/upgrade/security_database.sql.
# If you want to disable logons with old passwords
# after users' migration, set it to 0 (false).
# Makes no difference when used with original
# security2.fdb - it can't contain DES hash.
#
# Type: boolean
#
#LegacyHash = 1
# ----------------------------
# Which authentication method(s) should be used.
# "native" means use of only traditional interbase/firebird
# authentication with security database.
# "trusted" (Windows Only) makes use of window trusted authentication,
# and in some aspects this is the most secure way to authenticate.
# "mixed" means both methods may be used.
#
# Type: string
#
#Authentication = mixed
# ----------------------------
# 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 75 pages per client connection per database.
#
# Type: integer
#这里有改动
DefaultDbCachePages = 4096
# ----------------------------
# 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.
# Shadow database files are not preallocated.
#
# Type: integer
#
#DatabaseGrowthIncrement = 134217728
# ----------------------------
# File system cache usage
#
# Sets the threshold whether Firebird will use file system cache or not.
# File system caching is used if database cache pages (sets explicitly in
# database header or implicitly via DefaultDbCachePages setting) is less
# than MaxFileSystemCache value.
# To always use file system cache set MaxFileSystemCache to some big value.
# To never use file system cache set MaxFileSystemCache to zero.
#
# Type: integer, measured in database pages
#
#MaxFileSystemCache = 65536
# ----------------------------
# Temporary space management
#
# Temporary storage is used by the sorting module, it's also
# intended to store temporary datasets etc.
#
# The parameters below handle the allocation and caching policy
# for the temporary space manager. In previous Firebird versions,
# they were prefixed with "SortMem" instead of current "Temp".
#
# The smallest block size being allocated in the temporary storage.
# This value reflects the allocation granularity.
#
# Type: integer
#
#TempBlockSize = 1048576
#
# The maximum amount of the temporary space that can be cached
# in memory.
#
# For Classic servers, this setting is defaulted to 8 MB.
# Although it can be increased, the value applies to each client
# connection/server instance and thus consumes a lot of memory.

# Boolean evaluation method (complete or shortcut)
#
# If your SQL code depends on side-effects of full evaluation of OR

#
# Determines the number of seconds that the lock manager will wait after a
# conflict has been encountered before purging locks from dead processes

# ----------------------------
#
# How often the pages are flushed on disk
# (for databases with ForcedWrites=Off only)

#
# This option controls whether to call abort() when internal error or BUGCHECK
# is encountered thus invoke post-mortem debugger which can dump core suitable
# for off-line analysis. When disabled engine tries to minimize damage and
# continue execution.
#
# Note that setting this option to 1 makes engine produce traceable coredumps
# when something nasty like SIGSEGV happens inside UDF. On Windows enabling
# this option makes engine invoke JIT debugger facilities when errors happen.
#
# For debugging builds (DEV_BUILD), default value is 1 (Enabled)
#
# Type: boolean
#
#BugcheckAbort = 0
# Prior to Firebird 1.5 various SELECT expressions generated unnamed
# columns. This did not conform to the SQL standard. Fb 1.5 saw the
# introduction of default aliases for these unnamed columns. In some
# cases, particularly if string concatenation is used (via the ||
# operator) this breaks existing scripts.
#
# This setting will affect aliases generated via CONCATENATION,
# CURRENT_DATE, CURRENT_TIME, CURRENT_TIMESTAMP and EXTRACT. Setting
# the value to true will disable the alias generation. It is only
# recommended to be used where legacy scripts need to be supported.
# It will be marked deprecated in Firebird 2.0 and removed in
# Firebird 3.0.

# or may not prevent eventual inactive client disconnection for other OS.
#
# Normally, Firebird uses SO_KEEPALIVE socket option to keep track of

# Remove protection against opening databases on NFS mounted 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.
# DO NOT ENABLE THIS OPTION UNLESS YOU REALLY KNOW WHAT YOU ARE DOING.

# 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.
