Number of buffers in use.

U#

 

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.
