######################################### # # Firebird version 3.0 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 # permission of Ann Harrison @ IBPhoenix. # ######################################### # ---------------------------- # 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: # # 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 # ---------------------------- # 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. # However (as an additional method to have secure enhanced firebird # installation) one can disable remote access globally and re-enable # in databases.conf only for specific databases. # # Per-database configurable. # # Type: boolean # #RemoteAccess = true # ---------------------------- # 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. # # NOTE: THE EXTERNAL TABLE ENGINE FEATURE COULD BE USED TO COMPROMISE # THE SERVER/HOST AS WELL AS DATABASE SECURITY!! # # IT IS STRONGLY RECOMMENDED THAT THIS SETTING BE USED TO LIMIT # EXTERNAL TABLE LOCATIONS! # # 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 the root directory # of firebird. # # Default value 'Restrict UDF' provides the same restrictions # as in FB 1.0. To specify access to specific trees, enum all required # paths (for Windows this may be something like 'C:\ExternalFunctions', # for unix - '/db/extern;/mnt/extern'). # # # For this build Restrict UDF means Restrict /usr/lib/x86_64-linux-gnu/firebird/3.0/UDF # # NOTE: THE EXTERNAL FUNCTION ENGINE FEATURE COULD BE USED TO COMPROMISE # THE SERVER/HOST AS WELL AS DATABASE SECURITY!! # # IT IS STRONGLY RECOMMENDED THAT THIS SETTING BE USED TO LIMIT # EXTERNAL FUNCTION LOCATIONS! # # Type: string (special format) # # Debian maintainer note: UDFs can be used for remote code execution as the # 'firebird' user. See https://www.tenable.com/security/research/tra-2017-36 # (CVE-2017-11509) UdfAccess = None # ---------------------------- # 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 # 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) # #TempDirectories = # ---------------------------- # Trace configuration file for system audit # # Empty value means that system audit is turned off. # # Type: string # #AuditTraceConfigFile = # ---------------------------- # Maximum summary size of each user trace session's log files in MB. # When log files size reach this limit, trace session automatically # suspends until interactive user service read and delete some log files. # # 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. # Shadow database files are not preallocated. # # Per-database configurable. # # Type: integer # #DatabaseGrowthIncrement = 128M # ---------------------------- # 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 # # 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. # # Type: boolean # #RemoteFileOpenAbility = 0 # ---------------------------- # 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 = 1M # # 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 = 64M # ---------------------------- # # 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-1 for the client proof is the default for both client and server. # Additionally, the default client configuration (AuthClient) also supports new Srp256 # plugin using SHA-2 for the client proof. This enables backwards compatibility # with older Firebird 3 servers & clients but in order to meet NIST requirements # Srp256 should be used. To enforce NIST requirements on your server set # AuthServer=Srp256. Be aware that this breaks compatibility with older # than 3.0.4 clients. # # 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. # # Per-database configurable. # #AuthServer = Srp # # Per-connection and per-database configurable. # #AuthClient = Srp, Srp256, Legacy_Auth #Non Windows clients #AuthClient = Srp, Srp256, Win_Sspi, Legacy_Auth #Windows clients # # If you need to use server plugins that do not provide encryption key (both Legacy_Auth # & Win_Sspi) 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 Alleged RC4 # (key must be generated by auth plugin). # # Per-connection configurable. # #WireCryptPlugin = Arc4 # Key holder is a kind of temp storage for DB crypt keys. # There is no default for this kind of plugins. # #KeyHolderPlugin = # ---------------------------- # # 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. # # Type: boolean # # Per-database configurable. # ######################################################################### # Please understand what are you doing before enabling this feature !!! # ######################################################################### # #AllowEncryptedSecurityDatabase = false # ---------------------------- # # This parameter determines what providers will be used by firebird. # Format is the same as for the list of plugins (see a few lines before). # This is not strange because internally provider is just a kind of plugin. # # Type: string # # Per-database & per-connection configurable. # #Providers = Remote,Engine12,Loopback # ---------------------------- # # Determines the number of seconds that the lock manager will wait after a # conflict has been encountered before purging locks from dead processes # and doing extra deadlock scan cycle. Engine detects deadlocks instantly # in all normal cases, so this value affects things only if something goes # wrong. Setting it too low may degrade system performance. # # Per-database configurable. # # 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-Windows ports, # the default value is -1 (Disabled) # # Per-database configurable. # # Type: integer # #MaxUnflushedWrites = 100 # # Number of seconds during which unflushed writes will accumulate # before they are flushed, at the next transaction commit. For non-Windows # ports, the default value is -1 (Disabled) # # Per-database configurable. # # 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 # ---------------------------- # How COMMIT\ROLLBACK RETAINING handle GLOBAL TEMPORARY TABLE ON COMMIT DELETE ROWS # # GLOBAL TEMPORARY TABLE ON COMMIT DELETE ROWS (GTT) data is cleared on "hard" # commit (rollback) but should be preserved on commit(rollback) retaining. # Due to bug in initial implementation in Firebird 2.1 that data is not visible # for the application. This setting allows to preserve backward compatibility # (i.e. clear GTT data on commit\rollback retaining). # Value of 0 makes engine to not clear GTT data on commit\rollback retaining and # let application to see it. # Default value is 1 (clear GTT data on commit\rollback retaining). # Note: in Firebird 4 default value will be changed to 0 and this setting will # be removed at Firebird 5. # # Per-database configurable. # # Type: boolean # #ClearGTTAtRetaining = 1 # ---------------------------- # 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. # # Type: boolean # #RelaxedAliasChecking = 0 # ---------------------------- # Client Connection Settings (Basic) # # Seconds to wait before concluding an attempt to connect has failed. # # Per-connection configurable. # # Type: integer # #ConnectionTimeout = 180 # # Should connection over the wire be encrypted? # Has 3 different values: Required, Enabled or Disabled. Enabled behavior # depends on the other side's requirements. If both sides are set to Enabled, # the connection is encrypted when possible.
