From rawdevices configured datafiles to ASMLIB managed datafiles
Hello,
Assuming living database built on raw devices ( control file, online redo, all datafiles, datafiles for undo tablespace, datafiles for temp tablespace ) and raw devices visible to
oracle processes through unix/linux hard/soft links.
IS it possible to upgrade such database later when database was already in production to ASMLib? So ASMLib is later installed or added to the ORACLE_BASE configuration?
Could part of the datafiles be in ASMLib architecture and part on classic ( raw devices or files on filesystems )?
Is this upgrade possible directly or intermediate disk space is needed for datafiles migration from raw device datafile to ASMlib datafiles?
