Ivy 3.9 User Details loading very slow

Question

On a customers installation the User Details in the workflow ui are loading very slow. About 50 seconds.

URL: http://localhost:8081/ivy/wf/Webapp/index.html?pageId=admin%2Fuserform&user=GFKLK

The AAA System is set to Active Directory. After a click on user details i wait 50 seconds and then the following line appears in the server log.

LogId	119510222
SessionId	199
LogLevel	5
LogTimestamp	2017-08-04 10:07:30.080
SequenceNumber	87
LogMessage	Open directory context to naming and directory server 'ldap://SOME_SERVER_ADDRESS'
LogDetailMessage	-> client: 0:0:0:0:0:0:0:1 SOME_SERVER_ADDRESS -> thread: http-8081-Processor5 Class: JndiAuthenticationAndAuthorization Method: getJndiContext

It seems that the server tries to get some information from the ldap server and runs in a timeout. After that the user details page is shown. Confusing is the part "client: 0:0:0:0:0:0:0:1". Its an ipv6 address. Does the server try to fetch something via ipv6?

I disabled ipv6 in Windows but that didn't changed anything.

Have you seen a similar case? What can I do to investigate?

It looks like an ipv6 issue.

You have to configure the corresponding ilc file and set the java property -Djava.net.preferIPv4Stack=true.

A default .ilc file is locatedf in <engine>/bin/default.ilc. Copy it and rename it to the same name as the used .exe file. E.g. when you start the engine as a service, the XpertIvyServer2Service.exe is used, so and the ilc file must have the name XpertIvyServer2Service.ilc.

In the ilc file adapt the below line. If there is already a option set, add the property to the end of the line.

Before

#
# Additional vm arguments.
#
#ivy.vm.additional.options=

After the change, the # was removed and property was added:

#
# Additional vm arguments.
#
ivy.vm.additional.options=-Djava.net.preferIPv4Stack=true

A restart of the engine is required, for the changes to take effect.
