iManager hangs when moving objects.

Dear knowledgeable forum,

We are currently having a quite severe problem where our iManager hangs
very often when we are moving objects between organisational units.
We have tried both Firefox and Internet Explorer and get the exact same
result.

What happens and when:

When moving an object to another Organisational Unit nothing happens and
iManager stops responding. When you refresh the page, it can no longer
load but if you close all tabs and instances of the browser and open
iManager again you can login and maybe move one more object before it
happens again.

We thought it could be a local java issue but we are seeing this on all
computers we've tried and when it hangs, on the server it shows that the
java process is on 200%+ CPU.

Restarting tomcat helps with the CPU load but only last a few minutes.

The what to the question "What has changed since it worked?" is that
we've increased the number of useraccounts by over 100%.
There is now a OU with over 1000 accounts waiting to be sorted but with
iManager hanging all the time it's rough work.

Server:
6Gb RAM
4 vCPU
Java version 1.6.0
SLES 11 SP3
Product Version: eDirectory for Linux x86_64 v8.8 SP8 [DS]
Binary Version: 20807.11

Any ideas?

Re: iManager hangs when moving objects.

If you try a new install of iManager Workstation on your workstation, how
does that behave with this object move? The current version is 3.0, but a
test with 2.7 SP7 Patch-whatever would also suffice, just so long as it is
a clean install.

iManager workstation is basically a little archive file that you extract
on your local workstation and then run (iManager.sh or equivalent) and it
looks like a thick client on your computer. As a result, it's great for
testing iManager without needing to work on the server side.

Re: iManager hangs when moving objects.

Not quite sure how to do this since I downloaded a zip archive from download.novell.com saying iManager workstation 3 butI can't find out how to run it as per your instructions?
"Your NetIQ iManager 3.0.0 profile cannot be loaded. It may be missing or inaccessible."

I get the client up to login etc but not sure where and how to connect it to our server from my machine?

Re: iManager hangs when moving objects.

Be sure you installed NICI per the iManager Workstation documentation:

Re: iManager hangs when moving objects.

I've downloaded "iMan_300_workstation_win_x86_64.zip" which doesn't contain an "install" folder.

There is:
bin
preinstalls (containing "NICI_wx64.msi")
tomcat

So unsure how to proceed since there is no "install".

NICI is required for any client or server using NCP and since iManager
Workstation is a client, it is included. If you do not know that it is
installed and as current as iManager, find the executable in the iManager
Workstation media and be sure to 'Run As Administrator' because otherwise
it will probably not work completely and properly (thanks microsoft).

Yes, still sounds to me like a NICI issue. If it loads you should have
three fields, Username, Password, and Tree. If you do not get that far,
iManager is broken in a very fundamental and unusual way.

Re: iManager hangs when moving objects.

Thank you very much for your help!

I've managed to get a connection working with the production servers and will begin my tests right away!

Apologies for my basic level of Novell 🙂

Re: iManager hangs when moving objects.

Alright, I have now tried with my local install of iManager 3.0 and while it lasted a bit longer, it suffered the same fate.
I managed to move about 5 accounts before it got stuck and here is a small gif showing what happens when it gets stuck:

It also seems the javaw.exe process gets stuck and actually drains memory so suspecting that there is a memory leak issue at hand.

This is all very strange still since the only thing that has changed is the vast number of recent accounts we now manage.
Is there any limitations to objects handled by iManager so that Java doesn't crash? Perhaps different ways to work around it?

However, since there might be a memory-leak at hand, an official ticket to Novell might be better suited.
