Very slow response displaying OrgChart in IDM Apps 4.5

Hi,

We have IDM application 4.5. We see the organization chart response is taking too long time more than 2-3 minutes to display the chart.

In eDirectory, we have all the required attributes are indexed.

Please let me know what would be the root cause for this slow response and how to resolve it.

Thanks in advance.

Re: Very slow response displaying OrgChart in IDM Apps 4.5

I saw a slow performance in the IDM 4.7 User Application (IDM Dash) at some point and fixed this by increasing the eDirectory cache on the eDirectory Server configured for the IDM User Application.

How many Users/Objects you have in your tree? In my case it was apprx. 80k and I configured the cache for eDirectory to 1 GB!

Kind regards,

Thorsten

Some of the attributes for UA are fairly large and verbose, so perhaps
more dib cache can help in that case, but that seems a little unlikely.

But a Gig or two fo DIB cache should not be an issue. Nor hurt.

Hi,

Initial dib cache hard limit was set to default (which was 0.2 GB equivalent KB value).

Then I changed this to 2GB once, and checked login to IDM but still delayed to display org chart.

Then I change again to 4 GB equiv KB value but still taking very long time. (More than 3 minutes).

Please find the DIB cache size stats from iMonitor.

Note: When I login as uaadmin user, it quickly displays orgchart but uaadmin doesnot have any reportees.

Re: Very slow response displaying OrgChart in IDM Apps 4.5

Hi,

I noticed below by further testing.

User001 created newly without manager & direct reports. So orgchart shows only this user and it shows immediately after login, no delays.

I added 1 direct reportee to above user, now orgchart took around 30 secs.
I added another 1, now 2 reportees total, orgchart took 1 minute to display.

if reportees are more, it takes very long time. This is my observation on this testing.

I am unable to find the root case for this orgchart slow response. Please provide your comments / thought on this.

Thanks

Re: Very slow response displaying OrgChart in IDM Apps 4.5

Hello,

My experience is that the DIB cache on a Linux box doesn't change performance drastically. I guess it is because Linux does
quite well caching the file system itself. Indexing is crucial for performance but you say you have checked that.

What about the entity you use for the org chart? Try to minimize the entity as much as possible, include only the attributes
that is required. How large is a user (number of attributes and size of the attributes)? If you allow large images create a
policy that scale them down to smaller thumbnail and use the thumbnail attribute in the org chart.

Best regards,
Tobias

Re: Very slow response displaying OrgChart in IDM Apps 4.5

Hi,

We have created a new entity for the manager - user relationship and mapped it to relationship. But still we see its very slow.
We also got to know that from MF that this is issue due to ldap query - querying the dynamic groups, and it take so long time to get the result.

In our environment, we have some 100-500 dynamic groups for some functionality and mapping. We cant get rid of this.

Please let me know if you have any ideas to resolve it temporarily.

Thanks
