Hi friends
I have few doubts in rac environment
1.In 2 node rac while adding datafile to tablespace if you forget to metion '+'then what will happen whether it is going to be create or it throws an error if it creates where exactly located and other node users how to work on that tablespace .what all steps to perform that datafile is usefull for all node users.
2. In Rac environment how to check how many sessions connected to particular node.
3)In Rac any node is evicted due to network failure then after we rebuild the network .Is there any steps to do manually to access the failure node after rebuilding the network or it will automatically available in cluster group which service is perform this activity.
4.While configuring clusterware you choose voting disk and ocr disk location and which redundancy you will choose suppose if you go for normal redundancy how many disks you can select for each file either one or two?.

As MC said, test it. I just did. Two points you will want to confirm: first, does the directory path you give actually exist? Where will the file be created (or will it be created?) if the path does not exit? That's easy, and doesn't need a cluster to test. Second, can you create a datafile on non-shared storage when logged onto a RAC database? And if you can, will it be usable from all instances?
