The iSQL*Plus interface uses the security model based on the RESTRICT option, which you saw earlier in the chapter. Thus, you can t execute commands such as HOST, @, and SPOOL from iSQL*Plus, meaning that you can t reference the local file system using an iSQL*Plus interface. Note that iSQL*Plus does not use a login.sql file as the SQL*Plus interface does. When you first log in, only the global login file, glogin.sql, is read. This file is usually located in the $ORACLE_HOME/ sqlplus/admin directory. Users thus cannot customize the environment for their use to the extent they can in SQL*Plus. You can further restrict access to the iSQL*Plus server to a limited set of databases, by editing the web.xml file located in the $ORACLE_HOME/oc4j/j2ee/oc4j-applications/applications/ isqlplus/isqlplus/WEB-INF directory. Here s an example, showing how the user s access is limited to two databases, prod1 and cust1: <init-param> <param-name>iSQLPlusConnectIdList</param-name> <description> prod1;cust1 </description> <param-value>ora10g;ora9i</param-value> </init-param> In the preceding web.xml file, the third line is where you specify the list of databases to which iSQL*Plus users are restricted. If you leave this line blank, users aren t restricted from accessing any database through iSQL*Plus.

For several reasons, including redundancy, several of the regular SQL*Plus commands do not work in the iSQL*Plus environment. The following are some of the important commands that you can t use in the iSQL*Plus environment: APPEND, DELETE, CHANGE, EDIT, INPUT, EXIT, QUIT, GET, HOST, SAVE, SPOOL, STORE, FLUSH, NEWPAGE, PAUSE, SQLPROMPT, TAB, TERMOUT, TRIMOUT, and TRIMSPOOL. Although you may be disappointed to see that so many of your old standby SQL*Plus commands are unavailable, the iSQL*Plus environment does give you a better display and capabilities for web reporting, which compensates for the drawbacks.

CHAPTER
Loading and Transforming Data
ne of your most common tasks as a DBA is loading data from external sources. Although you normally do this when you first populate a database, you frequently need to load data into various tables throughout the life of a production database. Traditionally, DBAs have used the SQL*Loader utility to load data from flat files into the Oracle database tables. Although SQL*Loader has always been an important tool for loading data into Oracle databases, Oracle also provides another way to load tables: using the external tables feature. External tables use SQL*Loader functionality and let you perform complex transformations on data before loading it into the database. Not only can you load data into your database, but with Oracle Database 10g, you can also unload data into external files. You can then use these files to load data into other Oracle databases. In many cases, especially in data warehouses, you need to transform the data you load. Oracle provides several means of performing data transformation within the database, including SQL and PL/SQL techniques. Additionally, Oracle Database 10g introduces the powerful MODEL clause, which enables you to create sophisticated multidimensional arrays and conduct complex interrow and interarray calculations, using simple SQL. Oracle provides a useful data replication feature called Oracle Streams, which lets you propagate changes from one database to another. You can use the Streams feature for various purposes, including the maintenance of a standby database. This chapter covers all of these topics related to loading and transforming data. First, it provides an overview of the extraction, transformation, and loading process.
