The Instant Client Enables you to install only the shared libraries required by Oracle Call Interface (OCI), Oracle C++ Call Interface (OCCI), Pro*C, or Java Database Connectivity (JDBC) OCI applications. This installation type requires much less disk space than the other Oracle Database Client installation types.

For more information about Instant Client, see Oracle Call Interface Programmer's Guide or Oracle Database JDBC Developer's Guide.

Included in the Instant Client installation is Instant Client Light. You may want to use this version of Instant Client if the applications generate error messages in American English only. Instant Client Light is beneficial to application that use one of the supported character sets and can accept error messages in American English. The following are the supported character sets:

• US7ASCII

• WE8DEC

• WE8MSWIN1252

• WE8ISO8859P1

• WE8EBCDIC37C for EBCDIC platforms only

• WE8EBCDIC1047 for EBCDIC platforms only

• UTF8

• AL32UTF8

• AL16UTF16

  The advantage of using Instant Client Light is that it has a smaller footprint than the regular Instant Client. The shared libraries, which an application must load, are only 34 MB as opposed to the 110 MB that regular Instant Client uses. Therefore, the applications use less memory.
