Browser-Based SQL*Plus
In 2001, Oracle released iSQL*Plus, a browser-based version of SQL*Plus that runs in a three-tier configuration. You access iSQL*Plus via a web browser on your PC. Beginning in Oracle Database 10g, iSQL*Plus runs as a Java 2 Enterprise Edition (J2EE) application server. It is installed by default with the database and runs on the database server.
iSQL*Plus is as compatible as possible with command-line SQL*Plus, but there are a few differences. Most obviously, the editing paradigm is different. You enter and edit commands using a text box in your browser window. Line-editing commands such as CHANGE and APPEND make no sense in that context and are not supported in iSQL*Plus.

Clients may now connect to iSQL*Plus via their browsers.
Use isqlplusctl ...
