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.
