still not sure what to choose (maybe you find all this tech talk a little overwhelming), use this rule of thumb: • On Windows, choose Superserver. Firebird 2.0 and 2.1 Quick Start 6 • On Linux, just application. The following sections show you how to test the server in each of these situations. Server check: Linux and other Unices Use the top command in a command shell to inspect the running processes interactively and launching the gsec utility. All these operations are described later on in this guide. Server check: Windows, running as service Open Control Panel -> Services (NT) or Control Panel -> Administrative

Installing Firebird 10 The following sections show you how to test the server on each platform. Server check: Linux and other Unices Use the top command in a command shell to inspect the running processes interactively firebird, depending on the type of Linux system and your Firebird installation package. Server check: Windows, running as service Use Win + R , type services.msc followed by Enter or [ OK ], or click do so now by right-clicking on the Firebird entry (or the Guardian) and choosing Start. Server check: Windows, running as application If Firebird is up and running as an application, it is represented

-N[O_VALIDITY] This switch is similar to the -i[nactive] switch above, except, it disabled all check constraints in the restored database. -NOD[BTRIGGERS] New switch from Firebird 2.1 which prevents Restore Mode 15 The source text of stored procedures (and several other types of object, such as CHECK constraints) is stored in a blob, as is the "compiled" BLR code. When you restore a database, the version of Firebird. tux> setenv_firebird 2.0 Firebird environment set for version 2.0. tux> # Check current ODS version (as root user!) tux> gstat -h employee|grep ODS ODS version

you will want to do once installation is complete is ping the server. This just gives you a reality check to ensure that your client machine is able to see the host machine in your network. For example, if machine. Shares, mapped drives or (on Unix) mounted SMB (Samba) filesystems will not work. The same rule applies to any databases that you create.

always page 0x03, however, this cannot be relied upon and if you need to do this, you should always check the database header page to determine where RDB$PAGES is to be found. The C code representation space, so record 1, for example, might appear in the “wrong” place in a dump as above.  This is a rule of relational databases, you can never know the order that data will be returned by a SELECT statement
