I'm not using RAC, but we have just put in OEM12c with a repository in an 11g database, (Solaris 10 isn't patched for 12c databases yet). So far, I'm not having issues. Have applied one patch to OEM software for some reason, and have patched 11g database TO 11.2.0.4.0. One caveat is that we cannot get the 12c agents to work on Solaris 9 yet. We have not released it to prime time yet, but looking good so far except for the Solaris 9 issue.

I'm working a new system design and wanted to use 12c RAC, but not all the applications which the database will support are compatible with 12c yet. So, I'm contemplating running 12c Grid Infrastructure with the 11g RDBMS. Just wondering if anyone has done this and if so, any gottchas I should be aware of.. Thanks in advance. -- Joel Patterson Sr. Database Administrator | Enterprise Integration Phone: 904-928-2790 | Fax: 904-733-4916 www.entint.com<http://www.entint.com/> [http://i1202.photobucket.com/albums/bb367/Entint/signaturev61.jpg]<http://www.entint.com/> [http://i1202.photobucket.com/albums/bb367/Entint/th_FaceBook1.jpg]<http://www.facebook.com/pages/Enterprise-Integration/212351215444231> [http://i1202.photobucket.com/albums/bb367/Entint/th_Twitter1.jpg] <http://twitter.com/#!/entint> [http://i1202.photobucket.com/albums/bb367/Entint/th_LinkedIn1.jpg] <http://www.linkedin.com/company/18276?trk=tyah> [http://i1202.photobucket.com/albums/bb367/Entint/th_YouTube1.jpg] <http://www.youtube.com/user/ValueofIT> This message (and any associated files) is intended only for the use of the addressee and may contain information that is confidential, subject to copyright or constitutes a trade secret.
