Information in this document applies to any platform.

When DBCA is launched by the oracle user OS account, the process gets tothe screen to select the ASM disk groups but no Disk Groups are available.

If we launch DBCA from Grid user account , the disk groups are available.

File permissions in <Grid_home>/bin/oracle executable not setproperly.
-also-
If the Oracle user is not a part of asmdba group; DBCA will not be able to seethe diskgroups, and may not start.

As root, change the file permissions of the oracle executableunder Grid_Home/bin to 6751:

# cd <Grid_Home>/bin
# chmod 6751 oracle
# ls -l oracle

-rwsr-s--x 1 grid oinstall 173515905 May 21 17:04oracle

This is the setuid bit, and this must be set in orderfor users, other than "Grid" user to have it work.
