Re: [IUG] jar errors at Mill startup; can't connect

Hi Jeff-

We are a consortium (10 institutions and multiple library sites) and just
went to Release 2011 1.1 last week.  Prior to our upgrade, I was getting an
increasing number of calls from our users about the inability to open
Millennium, as you described.  Innovative suggested an upgrade to Release
2011 would resolve this, and that may actually be the right answer, but the
situation got worse before it got better.  The day we upgraded every one of
our remote members within the consortium had the exact same issue (instead
of a handful, it was tens of users).  Millennium would begin to load, then
stop at some point along the way while loading a JAR file.  Sometimes, after
multiple tries they were successful, and other times they were not no matter
how many attempts.

This issue did not happen at the library where the Millennium server
resides, so I do think it was related to traffic on the network (either
local or at the host).  To that end, I suggested trying late in the day or
early in the morning to load the client.  I was working with all the IT
folks from the various libraries in our consortium and the one "fix" that
seemed to work consistently (I got the information here on the IUG List a
few weeks ago) was to copy the jarcache files from a working computer, then
go to the computer that isn't able to load Millennium and replace the
jarcache file with the one that is working:  Make sure you have read/write
permissions on that computer first.


To replace the JAR folder with one from a system that is currently working,
copy the "jarcache" folder from a computer which is known to work onto a
thumb-drive.

1.	As the Admin:  Go to a computer that is currently running Millennium
with no issues
2.	Go to the C: drive
3.	Open the Millennium folder
4.	Find the jarcache folder - COPY it to a thumb-drive
5.	As the Admin:  Go to your own computer's C: drive
6.	Open the Millennium folder
7.	Find the jarcache folder - DELETE it
8.	Copy the clean jarcache folder from your thumb-drive and paste it
into the Millennium folder
9.	Reboot

I will say, however, that since going on to Rel. 2011 1, and going through
this procedure on the affected computers, the situation does seem to have
been resolved.  The folks that had reported the issue in 2009B 1.4 are no
longer seeing that issue, and the folks that only had the issue after the
upgrade are fine.

Hope this helps.

Ruth

Subject: [IUG] jar errors at Mill startup; can't connect

We are having some strange intermittent startup problems with Millennium and
just wondering if anyone else is seeing this. III has opened a call with us.
My unscientific guess is that it has to do with busy times on the network,
firewall, bandwidth shaping on these networks or all three.
Millennium halts on startup with a jar error ("could not find
spring-oxm--1.0.4.jar").  The locations in question are connecting to us
over the Internet. Not all locations are reporting a problem. The oddest
thing is that a connection they opened early in the morning from the same IP
range stays open; they simply cannot open new connections on any other PC,
or any new Mill modules on the connected PC.

We are on Release 2009B 1.4;  all Mill clients are 1.6.0._02
