For testing purposes I've plugged a PDB from a single instance with ASM in a RAC CDB with ASM.
So far it was successfully, but I get a pending error message
select to_char(time,'HH24:MI DD.MM.') "time", name,cause,type,message,status from PDB_PLUG_IN_VIOLATIONS where name='PDB1' order by time desc;
time NAME CAUSE TYPE MESSAGE STATUS
-------------------- ---------- ---------- --------- ----------------------------------- ---------
10:43 25.02. PDB1 OPTION WARNING Database option RAC mismatch: PDB PENDING
installed version NULL. CDB
installed version 12.1.0.2.0.
Of course this behavior is accountable, because same options in source and target cdbs has to be installed as prerequisite for migration.
However it seems to work, but there is the pending warning in PDB_PLUG_IN_VIOLATIONS with missing RAC option of source PDB target.
Is it allowed (supported) at all, to migrate a non RAC PDB into a RAC CDB?
How can I resolve the missing RAC option message?
Thanks Peter
