- When allocated
- When the database is first activated on any member.
Note: Memory
is allocated on the CF and
not on any of the members.
If there is more than one CF then
each CF allocates
the same amount of memory.
- When freed
- When the database is deactivated on all members.
This is a global configuration parameter, meaning
that the same value is used for every member in the DB2 pureScale instance.
Note
that the memory on the CF is
only allocated once; when the database is first activated on any of
the members. You can monitor the consumption of the CF lock
memory using the current_cf_lock_size monitor
element.
