# 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

#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

# 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,

# 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,

#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
# SuperServer allocates 2048 pages for each database whilst Classic

#
# 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.
# Shadow database files are not preallocated.

# Type: integer
#
#DatabaseGrowthIncrement = 134217728
# ----------------------------
# 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.
#
# Type: integer, measured in database pages
#
#FileSystemCacheThreshold = 65536
# ----------------------------
# 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

# 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.
#
# Type: integer
#
#TempCacheLimit = 67108864
# ----------------------------
# Boolean evaluation method (complete or shortcut)
#
# If your SQL code depends on side-effects of full evaluation of OR
# and AND statements (right-hand-side terms), even if the expressions
# final result could be determined by just examining the value of the
# first term, you might need to turn this on.
#
# Type: boolean
#
#CompleteBooleanEvaluation = 0
# ----------------------------
#
# Determines the number of seconds that the lock manager will wait after a
# conflict has been encountered before purging locks from dead processes

# in all normal cases, so this value affects things only if something goes
# wrong. Setting it too low may degrade system performance.
#
# Type: integer
#
#DeadlockTimeout = 10
# ----------------------------
#
# How often the pages are flushed on disk
# (for databases with ForcedWrites=Off only)
#
# Number of unflushed writes which will accumulate before they are
# flushed, at the next transaction commit. For non-Win32 ports,
# the default value is -1 (Disabled)
#
# Type: integer
#
#MaxUnflushedWrites = 100
#
# Number of seconds during which unflushed writes will accumulate
# before they are flushed, at the next transaction commit. For non-Win32
# ports, the default value is -1 (Disabled)
#
# Type: integer
#
#MaxUnflushedWriteTime = 5
# ----------------------------
#
# 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.
#
# Type: boolean
#
#OldColumnNaming = 0
# Prior to Firebird 2.5 the SET clause of the UPDATE statement assigned
# columns in the user-defined order with the NEW column values being
# immediately accessible to the subsequent assignments. This did not
# conform to the SQL standard. Starting with Firebird 2.5, only OLD column
# values are accessible to all the assignments of the SET clause.
#
# Example of the old vs new behaviour:
#
# UPDATE T SET A = B, B = A
# old result: A gets equal to B, B doesn't change
# new result: A and B get their values exchanged
#
# Change this configuration option to 1 (true) only if your SQL code relies
# on the legacy semantics of the SET clause. It's provided as a temporary
# solution for backward compatibility issues and will be deprecated in
# future Firebird versions.
#
# Type: boolean
#
#OldSetClauseSemantics = 0
# ----------------------------
# Relaxing relation alias checking rules in SQL
#
# Since Firebird 2.0, strict alias checking rules were implemented in the SQL
# parser to accord with the SQL standard requirements. This setting allows
# these rules to be relaxed in order to allow legacy applications to run on
# Firebird 2.0.
# A setting of 1 (true) allows the parser to resolve a qualified column reference
# using the relation name, where an alias has been specified for that relation.
#
# For example, it allows a query such as:
# SELECT TABLE.X FROM TABLE A
#
# It is not recommended to enable this setting. It should be regarded as an
# interim workaround for porting untidy legacy code, until it is practicable to
# revise such code.
#
# CAUTION!
# There is no guarantee that this setting will be available in future Firebird
# versions.

# 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.

GEA = /home/tomay/Firebird/GEA.fdb
我在这里缺少什么?
我只是想看到它连接。
我试图
/databases/
在根目录中创建一个新文件夹,赋予它firebird
用户和组权限并将数据库放在那里。这次我试过了,瞧!建立连接并打开数据库。
It turns out that the default Firebird location for databases in arch linux is:
/var/lib/firebird/
which have thefirebird
user and group permissions by default. So after copying my .fdb database to this location I had tochown
it too:sudo chown firebird.firebird /var/lib/firebird/*.fdb
.Conclusion: never put the database somewhere in the user directory.
There are multiple problems
When you use
DatabaseAccess = None
you can only connect using the alias defined inaliases.conf
(ordatabases.conf
in Firebird 3 and higher), not by specifying the database path.So, for example in FlameRobin in the field 'Database path' you should use
GEA
instead of the path/home/tomay/Firebird/GEA.fdb
.Firebird is - normally - a server process, and the user for a server process does not normally have access to a normal users home directory.
You need to put the database outside of your home directory, and make sure both the folder and the file itself have sufficient access rights for the user running the firebird process (usually the user firebird), or to the group containing that user (usually the group firebird).
Specifically, the directory should be
drwxrwx---
(or chmod 770) to the firebird group and user), and the file should be-rw-rw----
(or chmod 660) to the firebird group and user. See also What file and directory permissions to set for database files on Linux?Also, if you use
isql-fb GEA
instead ofisql-fb localhost:GEA
, the database will be accessed using Firebird Embedded and not through the server process, and in that case your own user will need sufficient access to the database file and certain shared lock files as well. You can achieve this by adding yourself to the firebird group and logging out and back in.
