There are many different parameter files associated with an Oracle database, from a tnsnames.ora file on a client workstation (used to find a server on the network), to a listener.ora file on the server (for the network listener startup), to the sqlnet.ora, cman.ora, and ldap.ora files, to name a few. The most important parameter file, however, is the database s parameter file without this, we cannot even get a database started. The remaining files are important; all of them are related to networking and getting connected to the database. However, they are beyond the scope of our discussion. For information on their configuration and setup, I refer you to the Net Services Administrator s Guide. Typically as a developer, these files would be set up for you, not by you. The parameter file for a database is commonly known as an init file, or an init.ora file. This is due to its historic default name, which is init<ORACLE_SID>.ora. I term it the historic default name because starting with Oracle9i Release 1, a vastly improved method of storing parameter settings for the database was introduced: the server parameter file, or simply SPFILE. This file has the default name of spfile<ORACLE_SID>.ora. We ll take a look at both kinds of parameter files in turn.

Note If you re unfamiliar with the term SID or ORACLE_SID, a full definition is called for. The SID is a site identifier. It and ORACLE_HOME (where the Oracle software is installed) are hashed together in UNIX to create a unique key name for attaching an SGA. If your ORACLE_SID or ORACLE_HOME is not set correctly, you ll get the ORACLE NOT AVAILABLE error, since you can t attach to a shared memory segment that is identified by this unique key. On Windows, shared memory isn t used in the same fashion as UNIX, but the SID is still important. You can have more than one database on the same ORACLE_HOME, so you need a way to uniquely identify each one, along with their configuration files.

Without a parameter file, you cannot start an Oracle database. This makes the parameter file fairly important, and as of Oracle9i Release 2 (versions 9.2 and above), the backup and recovery tool Recovery Manager (RMAN) recognizes this file s importance and will allow you to include the server parameter file (but not the legacy init.ora parameter file type) in your backup set. However, since it is simply a plain text file, which you can create with any text editor, it is not a file you have to necessarily guard with your life. You can re-create it, as long as you know what was in it (e.g., you can retrieve that information from the database s alert log, if you have access to that). We will now examine each type of parameter file (init.ora and SPFILE) in turn, but before we do that, let s see what a database parameter file looks like.

In simple terms, a database parameter may be thought of as a key and value pair. You saw an important parameter, DB_NAME, in the preceding chapter. The DB_NAME parameter was stored simply as db_name = ora10g. The key here is DB_NAME and the value is ora10g that is our key/value pair. In order to see the current value of an instance parameter, you can query the V$ view V$PARAMETER. Alternatively, in SQL*Plus you can use the SHOW PARAMETER command, for example: sys@ORA10G> select value 2 from v$parameter 3 where name = 'pga_aggregate_target'; VALUE ------------------------------------------------------------------------------1073741824 sys@ORA10G> show parameter pga_agg NAME TYPE VALUE ------------------------------------ ----------- -----------------------------pga_aggregate_target big integer 1G Both outputs show basically the same information, although you can get more information from V$PARAMETER (there are many more columns to choose from than displayed in this example). But SHOW PARAMETER wins for me in ease of use and the fact that it wildcards automatically. Notice that I typed in only pga_agg; SHOW PARAMETER adds % to the front and back.

If you counted the number of documented parameters that you may set in each of the database versions 9.0.1, 9.2.0, and 10.1.0, you would probably find 251, 258, and 255 different parameters, respectively (I m sure there could be additional parameters available on an
