Impact of adding users through LDAP on system performance

0
Sripriya Karimpuzhasriram (1●3●48●52) | asked Aug 06 '13, 2:41 p.m.

Hello team,

We had a few questions regarding the impact on the RAM application due to the addition of active directory groups.

We are planning to add 70,000+ users from around 15 Active Directory Groups to each and every community as detailed below:

  • Number of users in each Active Directory Group = 5000
  • Number of Active Directory Groups expecting to be added to each community = 15

Therefore,

  • Total number of users in each community = 75000
  • Total number of communities = 40

We have a few questions :

  1. When the job runs every Saturday to update the RAM user group with the LDAP active directory. Would there be any negative impact in the system performance while this job runs as it updates this large set of user base?
  2. Would there be any other impact on the system due to addition of this large user base to the application?
  3. Is it possible to add more than one active directory group to a RAM User group? (I am guessing no, but would like to confirm).

Thanks in advance.

Regards,

Sripriya

  1. The sync. is on a low priority background thread ... but, at the end of the day it will need resources to drive the sync ... and depending on the latency to LDAP, it may take some time.
  2. Depending on how long will the sync. last .... there prop. is going to be some degradation, in particular the first time around.
  3. Not today :-( ... open an Enhancement request.

Hi Sripriya,

I'm not that familiar with RAM but if your application is deployed on a WebSphere server,
you could check the following article and video:
- [Article] "Optimizing performance with WebSphere LDAP Configurations":  https://jazz.net/library/article/1143/
- [Video] "Adv. LDAP filtering techniques": http://publib.boulder.ibm.com/infocenter/ieduasst/imv1r0/index.jsp?topic=/com.ibm.iea.infosphere_is/infosphere_is/8.5/configuration/LDAP_Filtering/player.html

Hope this helps.
Regards,
Stéphane
