WOS_CONTAINER_STORAGE
Monitors information about WOS storage, which is divided into regions. Each region allocates blocks of a specific size to store rows.
Note: The WOS allocator can use large amounts of virtual memory without assigning physical memory.
Column Name | Data Type | Description |
---|---|---|
NODE_NAME |
VARCHAR |
The node name for which information is listed. |
WOS_TYPE |
VARCHAR |
Returns one of the following:
|
WOS_ALLOCATION_REGION |
VARCHAR |
The block size allocated by region in KB. The summary line sums the amount of memory used by all regions. |
REGION_VIRTUAL_SIZE_KB |
INTEGER |
The amount of virtual memory in use by region in KB. Virtual size is greater than or equal to allocated size, which is greater than or equal to in-use size. |
REGION_ALLOCATED_SIZE_KB |
INTEGER |
The amount of physical memory in use by a particular region in KB. |
REGION_IN_USE_SIZE_KB |
INTEGER |
The actual amount of data stored by the region in KB. The amount of memory used by the WOS is typically capped at one quarter physical memory per node. |
REGION_SMALL_RELEASE_COUNT |
INTEGER |
Internal use only |
REGION_BIG_RELEASE_COUNT |
INTEGER |
Internal use only |
EXTRA_RESERVED_BYTES |
INTEGER |
The amount of extra memory allocated to maintain WOS sort information. |
EXTRA_USED_BYTES |
INTEGER |
The amount of memory in use currently to maintain the WOS sort information. |
