[midPoint] AD LDAP resource memory usage

[Davy Priem]

Hi Radovan,

I think we’ve hit bug MID-5284. Currently running on git-v3.9support-132-gd86f841, I deleted the schema part and did let Midpoint refresh the schema. XML is now 551kB instead of 100MB so issues is fixed.

Thanks for the help.

What makes it even worse is that the ConnId framework does not have any proper mechanism to share data between connector instances. Therefore each connector instance has to keep the schema separately. This may be also combined in changes in Apache Directory API that might also increase the memory consumption for the schema. Systematic solution to this problem will need changes to ConnId framework.

Please try to delete the <schema> part of the resource and keep just the generationConstraints. The schema should be re-generated and it should be considerable smaller.

I don’t know why the schema suddenly became so big. I’ve cheched the resource and the generationConstraints  as mentioned bellow, is still there. Anyone having the same issue? I’ve tested with latest support-3.9 (standalone on centos 7) in combination with ADLDAP connector 1.6.1, 2.0 and 2.1.
