Hi,
we have a rather large dogtag install here and the ldap-info is getting
hard to handle (right now in the ~75Gb range).
Are there any recomended ways to partition the data ? I am thinking of
migrating all expired and revoked certificates to a chainend ldap-instance
and keep only the "valid" certificates data in direct access to the CA
instances.
The migration from the "valid" partition to the "expired" partition
will
have to be done outside of dogtag and the 389ds-ldaps, probably by a script
at night (it probably could be integrated into the expire runs the dogtag
does, although)
Has a thing like this been done yet? What were the experiences ? What sould
I look out for ?
Mit freundlichen Grüßen,

Alexander,
Can you define "hard to handle"? What version of Dogtag are you using? Are you
running into performance degradation? Unfortunately, it likely won't be too easy to
segregate this data. In dogtag 10.2 there should be a scheduled job that regularly runs
through and removes all expired certs:
jobsScheduler.impl.UnpublishExpiredJob.class=com.netscape.cms.jobs.UnpublishExpiredJob
jobsScheduler.job.unpublishExpiredCerts.cron=0 0 * * 6
Thanks in advance.

Thank you Dave for bringing this email to my attention...somehow it got
slipped by me.
I just want to point out that if you do choose to "remove" certs from
the internal ldap repository, please do not remove any certs that are
revoked but not yet expired. Doing so will cause your CRL generation to
miss the revoked certificates, and render them valid when checked upon
by clients. It would be a big security violation of PKI.
regards,
Christina

Yes, I am planing to move only the expired (or revoked-expired certs).
While we do not really use the CRL any more (OCSP is the thing nowadays
:-), we keep it for compatibility...

Good to know. Though as far as Dogtag goes, OCSP gets its CRL from the
CA, where CA generates its CRL from the certs in its internal ldap db.
CA needs to keep its CRL accurate and updated for the whole PKI to work
properly.

Alexander,
Can you define "hard to handle"?
Hard to handle is a stock of over 4 Million certificates, of which about
10% are valid ones. The ldap database is with the indexes in the 100Gb
range, LDIF Backups take more than three hours and might fail if too many
changes occur during the night time we run them.
What version of Dogtag are you using?
10.1. something (= the version that came out in February this year, but the
history in that ldap is migrated since around 2007)
Are you running into performance degradation?
Yes, we had a perfomenace degradation , but that was a lookup error in the
code (I really have to get around to send our fixes here back to you)
Unfortunately, it likely won't be too easy to segregate this data. In
dogtag 10.2 there should be a scheduled job that regularly runs
through and
removes all expired certs:
jobsScheduler.impl.UnpublishExpiredJob.class=com.netscape.cms.jobs.UnpublishExpiredJob
jobsScheduler.job.unpublishExpiredCerts.cron=0 0 * * 6
Thanks for the pointer, I'll try to attach to this one.
Mit freundlichen Grüßen,
Alexander Jung
