Re: Global Index on Partition Table

Hopefully I'm understanding your question completely, but yes, with the 
partition maintenance, if you are exchanging partitions, then you do need to 
update the indexes as well or they will become unusable...
Are you looking if you need validation or not or if you need to rebuild them?  
That's what I can't tell if you are questioning...

Hi
 
I had 2 Tb table with Quarterly Partition and has 5 Global index. When we are 
doing quarterly maintenance and exchanging the partition  we are using the 
Clause
 
WITHOUT VALIDATION UPDATE GLOBAL INDEXES
 
As two of them are Unique index and so I think VALIDATION is anyway done. 
Question is that how it impact the Indexes ? Do I really need to Rebuild the 
index in the future or it is fine. 
 
Actually Earlier partition maintenance are not done with above clause leaving 
Index in Unusable state but adding the above will avoid this and save downtime 
which is big due to several big indexes as well as DB in LOGGING mode due to 
Standby database.
 
TIA
Sanjay
