Hi
I will be upgrading to db2 v10.5 from v9.5 . The upgrade path will be v9.5 to v9.7 and to v10.5
I need to convert the DMS tablespaces to use automatic storage.
As per the documentation , I need to do the following steps
1> enable the database to use automatic storage with the 'ALTER DATABASE' statement
2> For each tablespace:
Issue the ALTER TABLESPACE statement, specifying the MANAGED BY AUTOMATIC STORAGE clause
3> Issue the ALTER TABLESPACE statement again, this time specifying the REBALANCE option
My database is 4TB. The 2-hop upgrade needs to be done in minimal time
There will not be sufficient time to rebalance every tablespace in the database.
my questions :
> Can the upgraded database be released for use while rebalance is running ?
> Do I need to convert all the tablespaces at once ? or can the database operate with a mix of DMS + autostorage tablespaces
> Is it necessary to have seperate storage paths for data and index tablespaces ?
Regards
Warren
