Hi, guys, here is the solution. when you install ORACLE RAC based upon SVM, you need SUNWudlm packages (in SunCluster_Oracle_RAC_FRAMEWORK and SunCluster_Oracle_RAC_SVM directory), and you need ORACLE udlm package named "ORCLudlm", this package comes together with your ORACLE installation program "Disk1".
this package needs to be installed on both side of your RAC servers. Probably you need to reboot your SunCluster after installation. yours, Rhine This message posted from opensolaris.org
