How are you?

 

Here you have a procedure to install and create a database with ASM diskgroups with 4096 sector size.

 

If you want to use ASMLib please make sure you have the following version and configuration:

Preparing the asm_diskstring to have ORCL:* and /dev/mapper (with the specific disks for GRID and CONF diskgroups)

Change asm_diskstring in the file and recreate the spfile as: create spfile='+GRID' from pfile='/home/grid/spfile-neto.ora';

After adding the ORCL:* string and create the diskgroups.

Using DBCA, the installer will try to create the spfile on the same diskgroup as datafiles and it will fail (because it's 4096 bytes).

 

Please don't click finish on DBCA, save the scripts, modify the spfile to +CONF diskgroup.
