all, I have a simple procedure which contain only select statement and print a result. when executing that procedure let say on node 1 (RAC - 3 nodes), and I shutdown abort on node 1 (failover simulatiion), I got ORA-25408 consistently. session successfully failedover to other node, but the execution of procedure is stopped. Is it expected behavior or a bug?? i found bug no. 6767933 so far... thanks for your sharing... -- regards ujang
