fbsvcmgr - access services API of Firebird
Firebird (like interbase 6 and before) never had a way to access services API from command line. With the exception of -service switch of gbak(1) and total use of services API in gsec(1) since version 2.0, to use services one had to use third party GUI or write himself a program using C or other programming language. Use of GUI is almost always not a problem, when you work with local machine or machine in your LAN. But in case, when you connect to remote unix server using any text-only connection, use of services is almost impossible. And this is really a problem sometimes.
The fbsvcmgr utility solves this problem. With it you may use any service, implemented by firebird. To use this utility you should be familiar with firebird services API - fbsvcmgr does NOT emulate traditional utilities' switches, it is just frontend to the services API.
The first required parameter of command line is services manager you want to connect to. For local connection use simply service_mgr, to attach to remote machine something like hostname:service_mgr is required. When required, additional service parameter blocks (SPB), including any values, follow. Any of them may (or may not) be prefixed with single - (minus) sign for clarity. For long command lines, typical for fbsvcmgr, use of '-' makes command line better human-readable and has no other effects.
fbsvcmgr service_mgr user sysdba password \ masterke action_db_stats \ dbname employee sts_hdr_pages
fbsvcmgr service_mgr -user sysdba -password \ masterke -action_db_stats -dbname \ employee -sts_hdr_pages
Syntax of service parameter blocks, as understood by fbsvcmgr, almost exactly matches the one you may see in ibase.h include file or Borland InterBase 6.0 API documentation. To save typing and make command line a bit shorter, slightly abbreviated form is used. All SPB parameters have one of two forms: isc_spb_VALUE or isc_VALUE1_svc_VALUE2. Accordingly in the first case you should type simply VALUE, and for the second - VALUE1_VALUE2. For example:
present in ibase.h becomes ------------------------- ----------------- isc_spb_dbname dbname isc_action_svc_backup action_backup isc_spb_sec_username sec_username isc_info_svc_get_env_lock info_get_env_lock
and so on. As an exception, isc_spb_user_name may be specified as either user_name or simply user.
The full description of all SPB parameters can be found int the InterBase 6.0 beta documentation. It is some 40 pages long, so it is not duplicated here. There are a couple of differences, though, which are described below. Another reference is the ibase.h file distributed by the Firebird project.
- multiple actions in single request
- Using fbsvcmgr you may perform single action (and get results of it's
execution when available) or get multiple information items from services
manager. For example:
fbsvcmgr service_mgr -user sysdba -password masterke -action_display_user
will list all users of local firebird server:
SYSDBA Sql Server Administrator 0 0 QA_USER1 0 0 QA_USER2 0 0 QA_USER3 0 0 QA_USER4 0 0 QA_USER5 0 0 GUEST 0 0 SHUT1 0 0 SHUT2 0 0 QATEST 0 0
fbsvcmgr service_mgr -user sysdba -password masterke \ -info_server_version -info_implementation
will report both server version and it's implementation:
Server version: LI-T188.8.131.5240 Firebird 2.1 Alpha 1 Server implementation: Firebird/linux AMD64
But attempt to mix all of this in single command line:
fbsvcmgr service_mgr -user sysdba -password masterke \ -action_display_user -info_server_version -info_implementation
raises an error:
Unknown switch "-info_server_version"
- Buggy documentation
- Some parameters have buggy form in Borland beta documentation. When in
trouble, consult ibase.h first for correct form.
isc_spb_rpr_list_limbo_trans was forgotten in Borland beta documentation, but present in fbsvcmgr.
- No licensing stuff
- Everything concerning licensing was removed from interbase 6.0 and therefore not supported here.
- No access to config file
- Config file view/modification is not supported in firebird since 1.5 and therefore is not implemented here.
- Items added in firebird 2.1
- (Windows-only) Forces use of windows trusted authentication.
- (Only for actions related to security). It is equivalent to the -database switch of the gsec(1) utility. Note that in gsec(1) this switch is mostly used to specify remote server you want to administer. In fbsvcmgr the name of the server is already given in services manager name (first parameter), therefore this parameter in most cases is not needed.
- specify it to avoid executing database-wide triggers
