SHOW POOL
Displays information about the disposition of paged and nonpaged memory,
nonpaged dynamic storage pool, and paged dynamic storage pool.
Format
SHOW POOL [range][/ALL | /FREE | /HEADER | /NONPAGED |
/PAGED| /RING_BUFFER | /STATISTICS |
/SUMMARY| /TYPE=block-type]
Parameters
range
Range of virtual addresses in pool that SDA is to examine. You can express a
range using the following format:
m:n Range of virtual addresses in pool from m to n
m;n Range of virtual addresses in pool starting at m and continuing for n bytes
Qualifiers
/ALL
Displays the entire contents of allocated pool, including the pool lists, nonpaged
dynamic storage pool, and paged dynamic storage pool. This is the default
behavior of the SHOW POOL command.
/FREE
Displays the entire contents, both allocated and free, of the specified region or
regions of pool. You cannot use the /FREE qualifier when you use a range to
indicate a region of pool to be displayed.
/HEADER
Displays only the first 16 longwords of each data block found within the specified
region or regions of pool.
/NONPAGED
Displays the contents of the nonpaged dynamic storage pool currently in use.
/PAGED
Displays the contents of the paged dynamic storage pool currently in use.
/RING_BUFFER
Displays the contents of the nonpaged pool history ring buffer if pool-checking
has been enabled. Entries are displayed in reverse chronological order, that
is, the most recent to the least recent. You cannot use this qualifier with any
other SHOW POOL qualifier. This qualifier is most useful when analyzing crash
dumps; output might not be consistent when used on a running system.
/STATISTICS
Displays usage statistics about each pool list if pool-checking has been enabled.
For each list, the following are displayed:
• Queue header address
• Packet size
