IBM has announced that it will discontinue support for AIX 5.3 as of 4/30/12. IBM has previously stopped supporting all prior versions of AIX (5.2, 5.1, 4.3, etc.).
Our policy is to certify our software with the current version (AIX 7.1) and one previous version (AIX 6.1) of each applicable software product. This guarantees our customers plenty of time to upgrade software and hardware to keep their system up to date. For example, AIX 6.1 has been certified for Eclipse and supported by IBM since 2007, and AIX 5.3 had a lifespan of 8 years between 2004 and 2012.
Per this policy, Eclipse discontinued support for AIX 5.3 as of release 8.7.2 (see our database requirements for more details).
If you have any questions about your server’s OS level, or if you would like to discuss upgrade or migration paths, please open a service request or contact your sales representative.
Customers who wish to remain on an unsupported OS platform do so at their own risk, as neither IBM nor Eclipse will be able to provide technical support services for servers running unsupported OS levels. To receive technical support from the Eclipse Systems team, customers must have an active support contract in place with their hardware and software vendors. Additionally, customers on unsupported OS versions will be unable to upgrade to new versions of the Eclipse software.
