5.2.3.5 Controlling Access to Flash Cache and Flash Log

You can use IORM to manage access to flash cache and flash log.

You can use the flashcache and flashlog attributes in the interdatabase plan to control access to flash cache and flash log. When set in the interdatabase plan, these attributes control access by a specific database.

The following example shows how to disable flash cache and flash log for the prod_test and prod_dev databases. In the example, flash log is also disabled for the dw_test database.

CellCLI> ALTER IORMPLAN                                          -
         dbplan=((name=prod, flashcache=on, flashlog=on),        -
                (name=dw, flashcache=on, flashlog=on),           -
                (name=prod_test, flashcache=off, flashlog=off),  -
                (name=prod_dev, flashcache=off, flashlog=off),   -
                (name=dw_test, flashcache=on, flashlog=off))

You can also use these attributes in conjunction with other attributes. For example:

CellCLI> ALTER IORMPLAN                                                   -
         dbplan=((name=prod, share=8, flashcache=on, flashlog=on),        -
                (name=dw, share=6, flashcache=on, flashlog=on),           -
                (name=prod_test, share=2, flashcache=off, flashlog=off),  -
                (name=prod_dev, share=1, flashcache=off, flashlog=off),   -
                (name=dw_test, share=2, flashcache=on, flashlog=off),     -
                (name=other, share=1))

You do not need to explicitly set flashcache=on or flashlog=on because they are the default settings.
