With the constant changing of installation steps for the Oracle RDBMS Server and it components such as the Oracle Client Development S/W, it can get a bit frustrating searching for the current location and the filename(s). Prior to 10g, all components of the Oracle RDBMS Server product (Database, Client Development S/W, Client Runtime S/W, and sample code), were included in a single platform specific file. You unzipped this file and ran the installer once, selecting the pieces you wanted and then it installed them in a single attempt. If you then wanted a patchset on top of that base software, you downloaded it from My Oracle Support, and then used opatch to bring the software up to this patchset level. Quite frequently, customers would then go back to the base software to install a component such as the precompilers and would then corrupt the installation, having some pieces at the patchset level and other back at the base version. It was for this reason, among others, that Oracle Support recommended that an ORACLE_HOME should only one component, Database, Client Development, or Client Runtime. This helped to separate the RDBMS Server product into 3 separate and completely independent components. Starting in 10G, the product packaging team decided to move these components into separate installs on separate CDs (or at least in different folders). However, in some cases the options available on the Database installer's screens still allowed customers to choose the client component misleading the installer to believ they actually installed the client development software when it fact they had not.. Ultimately, the only supported client development s/w installation of the oci or precompilers must come from an installation using the Client labeled CD or download from OTN. The build team then made a small change in 11gR1 and then again in 11gR2. This note serves to provide a quick explanation of these changes and where to find the files needed to install the Oracle Client Development tools such as OCI, Pro*C/C++, or Pro*COBOL.
