Hi, Assuming your controlfiles will be in 2 disk groups +DG1 and +DG2 do the following -alter database backup controlfile to trace -Shutdown the database -Edit the controlfiles parameter to include both the diskgroups -Startup nomount -Recreate the controlfiles HTH Regards, Fairlie "Steiner, Randy" <RASTEIN@xxxxxxxx> wrote: I am running 10g with asm and currently 1 control file. If I want to multiplex the control file, I know I have to shutdown the database and make a copy of the control file, but since the control file is in asm how do I do the copy? I tried asmcmd, there is no cp command. Thanks Randy -- //www.freelists.org/webpage/oracle-l --------------------------------- Do you Yahoo!? With a free 1 GB, there's more in store with Yahoo! Mail.
