Quanah,

Yes that is the plan but till i moved to latest version with mdb, i have to live with it. Regarding upgrading to latest with mdb, how can i migrate from hdb to mdb with out downtime? can i add latest openldap with mdb as replica to existing older/hdb instance?

Thanks for all you suggestions Ram

Quanah,

Sorry i was searching for one attribute, i have close to 80mil entries.

Then these settings may be too low:

cachesize 100000 idlcachesize 300000

Essentally, cachesize needs to hold your working set of data (active entries). So this is saying slapd will only cache 100,000 active entries. It will then be removing/adding entries in blocks of one (cachefree defaults to 1 if not set). idlcachesize generally is 3x cachesize.

If your active set is > 100,000 users, then you need to increase the cachesize and idlcachesize parameters accordingly. You may also need to increase cachefree from its default of "1".

Overall, you would likely be much better served to switch to back-mdb, where you do not have to set any of these parameters at all.
