HP OpenVMS System Analysis Tools Manual
CLUE MEMORY
Displays memory- and pool-related information.
Format
CLUE MEMORY [/qualifier[,...]]
Parameters
None.
Qualifiers
/FILES
Displays information about page and swap file usage.
/FREE
Validates and displays dynamic nonpaged free packet list queue. (See
also /FULL.)
/FULL
Ignored except when used with /FREE or /GH. When used with /FREE, the
first 16 bytes of each entry on the free packet list is displayed. When
used with /GH, a list of the images that use each granularity hint
region is displayed.
/GH
Displays information about the granularity hint regions. (See also
/FULL.)
/LAYOUT
Decodes and displays much of the system virtual address space layout.
/LOOKASIDE
Validates the lookaside list queue heads and counts the elements for
each list.
/STATISTIC
Displays systemwide performance data such as page fault, I/O, pool,
lock manager, MSCP, and file system cache.
Description
The CLUE MEMORY command displays memory- and pool-related information.

The CLUE MEMORY/LOOKASIDE command summarizes the state of nonpageable
lookaside lists. For each list, an indication of whether the queue is
well formed is given. If a queue is not well formed or is invalid,
messages indicating what is wrong with the queue are displayed. This
command is analogous to the SDA command VALIDATE QUEUE.
These messages can also appear frequently when you use the VALIDATE
QUEUE command within an SDA session that is analyzing a running system.
In a running system, the composition of a queue can change while the
command is tracing its links, thus producing an error message.
