Effective in version 10.5.7, Informatica defers the provision of a product installer for AIX operating systems. You can continue to use your current Informatica applications on AIX. However, you cannot install or upgrade to Informatica 10.5.7 on an AIX operating system.
Deferred functionality is either not available or not supported in the current release. Informatica intends to reinstate it in an upcoming release, but might choose not to in accordance with changing market or technical circumstances.
