Hi all, nothing to add really to Tim's reply. Just one more: you might have to "pin" your nodes to run pre 11.2 databases on 11.2 CRS. You can use the olsnodes -s -t command to check if they are. When upgrading all nodes are pinned (Oracle obviously knows that there are pre 11.2 databases) automatically, but when adding a < 11.2 RDBMS home they won't be. See http://docs.oracle.com/cd/E11882_01/install.112/e24616/postinst.htm section 5.3 as well. Hope this helps, Martin -- http://martincarstenbach.wordpress.com http://www.linkedin.com/in/martincarstenbach -- //www.freelists.org/webpage/oracle-l
