CLUE MEMORY [/qualifier[,...]]





Displays information about page and swap file usage.


Validates and displays dynamic nonpaged free packet list queue. (See also /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.


Displays information about the granularity hint regions. (See also /FULL.)


Decodes and displays much of the system virtual address space layout.


Validates the lookaside list queue heads and counts the elements for each list.


Displays systemwide performance data such as page fault, I/O, pool, lock manager, MSCP, and file system cache.


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.
