Utilities

fb_lock_print

Be on the watch for the effects of the following changes to the Firebird command-line utilities.

fb_lock_print

Because v.2.5 maintains separate lock structures for each database on the server, fb_lock_print now requires a database path name in order to print the lock table. Include the new switch -d <path name> in the command line to specify the filesystem path to the database you wish to analyse.

Deprecated Features with Future Impact

In anticipation of the dropping of the intrinsic function isc_ddl from the Firebird 3 codebase, certain features currently available in the gdef and gpre tools are deprecated—meaning that, whilst they may work in V.2.5, they will fail in Firebird 3.

  • gdef will no longer be supported at all. Instead, isql should be used, with regular DDL commands.

  • For gpre pre-processing, replace all DDL operations with


              EXEC SQL
                EXECUTE IMMEDIATE "..."
              

  • In all custom applications, calls to isc_ddl must be replaced with SQL DDL statement requests.
