"EXCHANGE PARTITION" without option "INCLUDING INDEXES" leads to "UNSUABLE" local indexes

in Database DataWarehousing (MOSC) 1 commentAnswered ✓

Hi,

<Oracle Database 19c Enterprise Edition Release 19.0.0.0.0 - Production>


I could only found this documentation about "EXCHANGE PARTITION" : https://docs.oracle.com/database/121/VLDBG/GUID-E08650B4-06B1-43F9-91B0-FBF685A3B848.htm#VLDBG1156 and my concern is that we have recently discovered that when doing a "EXCHANGE PARTITION" without "INCLUDING INDEXES" the local indexes become all "UNSUABLE".

I have queries example to demonstrate this behavior :

Can you confirm that indeed it is expected to have the local indexes 'UNSUABLE' in such case ?

Can you confirm that any select query will never be able to use the local indexes if one of the subpartitions of the local indexes are mark as "UNSUABLE" ?
