  • Planning and Organizing a Database Planning for your database is the first step in organizing and implementing a database system. First define how the database will be used. This determines what type of database you need to create that will meet the needs of your business, for example, data warehousing, high online transaction processing, or general purpose. After you determine the purpose and type, you must outline the database architecture that will be used.

SQL*Loader SQL*Loader loads data from external files into tables of an Oracle database. It has a powerful data parsing engine that puts little limitation on the format of the data in the datafile. Direct-Load insert Direct-load insert can be used to copy data from one table to another table within the same database.

  • Redo Log History All transactions are recorded in the online redo log files. This allows for automatic recovery of transactions in the event of a database failure. If the database is configured for NOARCHIVELOG mode, no redo history is saved to archived log files, and recovery operations are limited and a loss of transaction work may occur. This is the result of the automatic recycling of log files, where older log files needed for recovery are overwritten and only the most recent part of the transaction history is available.

  • Before a database is created, the UNIX environment must be configured and the Oracle9i server must have already been installed. Four environment variables must be set: ORACLE_HOME, ORACLE_SID, PATH, LD_LIBRARY_PATH. ORACLE_HOME is the full path to the top directory in which the Oracle9i Server is installed. The directory for ORACLE_HOME should be supplied by the person who installed the server, usually the UNIX administrator or the DBA. ORACLE_SID is a user-definable name assigned to an instance of a database.
