Description
Mem: # mb
Current memory being used by this Adaptive Server IQ 
server, in megabytes.

The maximum number of megabytes used by this IQ 
server since it was started.
Item Description
U#
Number of blocks in use. 
#%
Percentage of database filled.
Buffers: 
U#
Number of buffers in use. 
Note: This value will grow to maximum number of buffers that fit in 
the main buffer cache. The number increments whenever a buffer is 
allocated, but only decrements when a buffer is destroyed, not when it 
is unlocked or flushed. When it decreases, you have hit the current limit 
of virtual memory available and new memory is coming from buffer 
cache or you have an error and insert has been rolled back and restarted. 
L#
Number of locked buffers. This number increments whenever you 
request a buffer. If you exceed the maximum while running a script, the 
command that exceeds it will fail and subsequent commands may 
complete incorrectly.
