Generally, you slapcat your existing HDB database to an LDIF file, update your configuration for slapd to use MDB instead, and then use slapadd to import the LDIF file. --Quanah -- Quanah Gibson-Mount Product Architect Symas Corporation Packaged, certified, and supported LDAP solutions powered by OpenLDAP: <http://www.symas.com>

Ok, but are there any casses where DB size can grow bigger then RAM and what will happen in that case?

It uses RAM in accordance to the size of the database, not the maxsize. Generally, you set the maxsize value to something really large and forget about it. I would note you already have a fairly large database. However, MDB should use significantly *less* RAM than your old back-hdb database overall, because your old back-hdb DB had to use multiple caches in RAM as a part of the slapd process (cachesize, idlcachesize, dncachesize) in addition to the BDB cache (set_cachesize in DB_CONFIG). --Quanah -- Quanah Gibson-Mount Product Architect Symas Corporation Packaged, certified, and supported LDAP solutions powered by OpenLDAP: <http://www.symas.com>

Quanah, Quick question regarding "maxsize" in mdb, slapd-mdb man page says we have to preallocate the db size based on future growth of your data, that means will it create a data.mdb of maxsize? what i read from docs is, mdb loads whole database into memory, is it right? if my db size is grater then my RAM how does mdb handles? do we have any configuration options to set RAM allocation for mdb as i may have other applications sharing the same RAM?

Are you positive the servers are in sync at this point? I.e., did you freshly reload from whatever you consider your golden master them after applying the patch? --Quanah -- Quanah Gibson-Mount Product Architect Symas Corporation Packaged, certified, and supported LDAP solutions powered by OpenLDAP: <http://www.symas.com>
