spaceProvEF
: Provisions the vault with the specified amount ofEF
storage space.spaceProvHC
: Provisions the vault with the specified amount ofHC
storage space.iopsProvEF
: Provisions the vault with the specified number of IOPS fromEF
storage.iopsProvHC
: Provisions the vault with the specified number of IOPS fromHC
storage.flashCacheProv

) indicating whether the vault is provisioned with access to Exadata Smart Flash Log. The default value istrue
.-
xrmemCacheProv
: Provisions the vault with the specified amount of Exadata RDMA Memory Cache (XRMEM cache) space.Use this attribute only on systems with
HC
orEF
storage, but not both. For systems withHC
andEF
storage, use the following media-specific XRMEM cache provisioning attributes. -
xrmemCacheProvEF
: Provisions the vault with the specified amount of XRMEM cache space associated withEF
media. -
xrmemCacheProvHC
: Provisions the vault with the specified amount of XRMEM cache space associated withHC
media.

To specify an amount of space, you can:
-
Use an integer value representing the number of bytes. The maximum value is
4503599626321920
. -
Specify a space value using suffixes
K
,KB
,M
,MB
,G

Use an integer value. The maximum value is
4294967295
. -
Use
unlimited
to specify an unlimited number of IOPS.

Specifying
0
(zero) as the value for a cache provisioning attribute (flashCacheProv
,xrmemCacheProv
,xrmemCacheProvEF
, orxrmemCacheProvHC
) effectively disables use of the corresponding cache for the vault.
