If you want a SGA larger than 2GB, you need to use 64-bit Oracle.Here’s a step-by-step guide for doing away with this error, by installing SQL*Plus Instant Client on Windows.

A larger word size lets you address larger chunks of memory as well. By addressing larger word sizes, many applications can run faster. You cannot run 64-bit software on a 32-bit OS (and processors). You must have a 64-bit OS (and processors) to be able to run 32-bit and 64-bit apps. Those applications that are 64-bit apps have a word size of 64 bits. The OS will look at code in chunks of memory called a 'word.' Those applications that are 32-bit apps have a word size of 32 bits. The difference between 32-bit and 64-bit software (not just limited to Oracle) lies at the difference in how your operating system executes code.In Disk1 of Oracle 9i, you will find a runInstaller utility. The OUI for the 32-bit version will be found with the media.When you fire up the Oracle Universal Installer (OUI), enter a new ORACE_HOME directory when prompted.So install Oracle 32-bit in a different directory than your 64-bit version and they will both coexist quite nicely. The two installs must reside in different ORACLE_HOME directories though. You can install Oracle 32-bit and Oracle 64-bit on the same server.
