Creating database under Ingres


Ingres is a relational database management system (RDBMS) that is based upon a research project from the University of California at Berkeley . There are two different versions of Ingres available: a public domain version, known as Ingres or Berkeley Ingres; and a commercial version currently marketed by Computer Associates, mostly known as OpenIngres,or Ingres II.

The easiest way to create a database ingres is to use the command line createdb

The syntax is as follows:
createdb mydatabase

Here it will use the default locations (II_DATABASE, II_WORK, II_CHECKPOINT, II_DUMP and II_JOURNAL).

Command option:

-dlocate:To specify the location type DATA
-wlocation:To specify the location type WORK
-clocation:To specify the location type CHECKPOINT
-blocatÄf:To specify the location type DUMP
-jlocation:To specify the location type JOURNAL

Example createdb

$ Createdb mydatabase
Creating database 'mydatabase. . .

Creating DBMS System Catalogs. . .
Modifying DBMS System Catalogs. . .
Creating Standard Catalog Interface. . .
Creating Front-end System Catalogs. . .

Creation of database 'mydatabase' completed successfully.

After specifying all rights, the following processes are effected:-

In the iidbdb (for Ingres installation of DataBase DataBase), the necessary information are compiled).

For the location type data, it adds a directory same as the database name where the file aaaaaaaa.cnf(configuration file) is placed.

Many files are created as system tables prior the options put forward (the createdb create catalogs for individuals OpenRoad - IDE graphic object Ingres - or ABF, or Star - federated databases - etc.)

You can detect where you are physically located by the infodb mydatabase

================== Wed Mar 14 22:21:38 2007 Database Information =================

The location ROOT, DATA also known as default location where all the tables will will be created (with location clause = (list of locations).
