Getting Slow Response From OID Server for One-Level LDAP Searches (Doc ID 1428908.1)

Last updated on SEPTEMBER 14, 2016

Applies to:

Oracle Internet Directory - Version 9.0.4 and later
Information in this document applies to any platform.

Symptoms

Some LDAP searches take a long time to respond, others return results as expected. This may be seen as a performance issue in other products or applications that use OID, in this case Oracle Access Manager (OAM) admin console was extremely slow to respond for all links.

The search that was getting the slow response was identified in the OID Server log with debugging enabled.

Using the same search filter and only changing the scope of the search shows very poor performance for a one-level search.

eg:
time ldapsearch -h oid.au.oracle.com -p 3060 -D cn=orcladmin -w <password> -s sub -b "obapp=PSC,o=Oblix,cn=OAM,cn=Products,cn=OracleContext,dc=au,dc=oracle,dc=com" "(objectclass=oblixDelegatedAdministratorAuxClass)"
real 0m0.115s
user 0m0.015s
sys 0m0.003s

time ldapsearch -h oid.au.oracle.com -p 3060 -D cn=orcladmin -w <password> -s one -b "obapp=PSC,o=Oblix,cn=OAM,cn=Products,cn=OracleContext,dc=au,dc=oracle,dc=com" "(objectclass=oblixDelegatedAdministratorAuxClass)"
real 0m22.744s
user 0m0.012s
sys 0m0.005s

time ldapsearch -h oid.au.oracle.com -p 3060 -D cn=orcladmin -w <password> -s base -b "obapp=PSC,o=Oblix,cn=OAM,cn=Products,cn=OracleContext,dc=au,dc=oracle,dc=com" "(objectclass=oblixDelegatedAdministratorAuxClass)"
real 0m0.066s
user 0m0.014s
sys 0m0.005s
