onstat -g afr command: Print allocated memory fragments

Use the onstat -g afr command to display information about the allocated memory fragments for a specified session or shared-memory pool. Each session is allocated a pool of shared memory.


Syntax:

>>-onstat-- -g--afr--+-pool_name----+--------------------------><
                     +-sessionid----+   
                     '-pool_address-'

This command requires an additional argument to specify either a pool name, a session ID, or a pool address. Each session is allocated a memory pool with the same name as the session ID.

The pool_name is the name of the shared-memory pool. Run the onstat -g mem command to identify the pool name.

The sessionid is the session ID. Run the onstat -g ses command to identify the session ID.

The pool_address is the address of the shared-memory pool. Run the onstat -g mem command or the onstat -g ses command to identify the pool address.
