OUD11g - Bad Performance of a Subtree Search on the Root DSE if the External Changelog is Enabled.
Last updated on MAY 17, 2018
Applies to:
Oracle Unified Directory - Version 11.1.2.0.0 and laterInformation in this document applies to any platform.
Symptoms
A subtree search on the root DSE can be lengthy if the number of changes in the external changelog is high.
Some applications need to perform this kind of search.
For instance, when ODSM tries to load the ACIs, it runs the following search:
[19/May/2014:16:37:47 +0200] SEARCH REQ conn=56 op=2 msgID=3 base="" scope=wholeSubtree filter="(aci=*)" attrs="aci,creatorsname,createtimestamp,modifiersname,modifytimestamp"
[19/May/2014:17:14:53 +0200] SEARCH RES conn=56 op=2 msgID=3 result=0 nentries=7 etime=2226455
[19/May/2014:17:14:53 +0200] SEARCH RES conn=56 op=2 msgID=3 result=0 nentries=7 etime=2226455
Changes
The OUD external changelog is enabled.
