I am having problems with a DFS Lock wait. I am copying data from table to another and no data is being copied (I can tell this by looking to see if the segment size is increasing). I so found this. http://forums.oracle.com/forums/thread.jspa?messageID=2231833 I then went to metalink and look up the bug. There is not much there. I did not even see the recommendation to bounce one node in the cluster in the bug report. I have seen this poster on several forums for a number of years. He seems to know what he is doing. where do you get the bug report info? To get details do I need to open a TAR? I searched the bug database and though the bug exists, there is not much there. We just migrated to 10.2.0.4, using 7 RAC nodes, with ASM. I plan to bounce the whole cluster including ASM, but this is not something I can do during the day. Has anyone else seen this ?
