Reviewing the Storage Control File

After you have extracted the storage control file, you must review it. Your storage control file is located in the directory that you specified. Check the following parameters in the control file and modify them as appropriate for your database needs. Once you have a storage layout that you are satisfied with, you are ready to continue with your upgrade.

NOTE:  You must carefully review and edit the storage control file to meet your needs. Every time you modify the file, you must validate it again. See Validating the Storage Control File.

Do not change the defaults for the following parameters in [Object 1] in the storage control file:

• IndexStogroup
• IndexBp
• PriQty
• SecQty
