>> - what does shm_key do again?
Allocates the DB database memory to use a shared memory segment (RAM)
rather than disk-based memory environment. It dramatically improves
data load times among other things.
Could you give an example of how to use/set this? I looked at the
Berkeley docs... And I certainly didn't realize this from their
documentation. Maybe I looked at the wrong thing.
This goes in the DB_CONFIG file, I assume? I see it requires an int -
does it really matter what I pick? I gather from the docs that it is
just a key.
No, it goes in slapd.conf in OpenLDAP 2.2 or later. It is documented in
the slapd-bdb manpage:
Specify a key for a shared memory BDB environment. By
default the BDB environment uses memory mapped files.
If a non-zero value is specified, it will be used as
the key to identify a shared memory region that will
house the environment.
From my slapd.conf:
