Thank you for the quick response.
I have spent a lot of time configuring version 2.4.40. Is there a guide
on how to upgrade to 2.4.44 and switch to back-mdb? we rolled out 2.4.40
today and would need to plan the next upgrade.
As long as it is linked to the same BDB libraries as your 2.4.40 build, it
is simply a drop in binary upgrade.
What tool do you recommend for monitoring ldap performance?
I suggest applying the operation duration patch:
<https://github.com/Zimbra/packages/blob/master/thirdparty/openldap/patches/ITS8054.patch>
That will tell you exactly how long each operation is taking in slapd, as
long as you have "stats" logging enabled. Then you can tell if the issue
is at the slapd server, or if there is something else in between that is
causing the delay that you see. My suspicion would be that there is
something else interfering.
As for migrating from hdb to mdb, it's generally straight forward. You'd
need to export your data database to LDIF, and then export cn=config, and
change the HDB specific bits to MDB, and drop the parameters specific to
HDB that aren't required for MDB.
If you want to see a basic cn=config templated configuration, you can look
at:
<http://www.openldap.org/devel/gitweb.cgi?p=openldap.git;a=blob_plain;f=tests/data/regressions/its8521/slapd-provider.ldif;hb=HEAD>
where @BACKEND@ can be any of bdb/hdb/mdb, and tweak as necessary from
there.
