getCacheDescriptor

[rpike]

Some of our users are receiving the following error message from Internet Explorer when trying to upload a file into Windchill: The operation: "getCacheDescriptor" failed. I don't see anything in the Windchill logs. Is this a browser issue? The environment is Windchill 9.1/Windows Server 2003/Oracle/JRE 1.5.0_16. Any ideas would be much appreciated. Thanks.

Hi Ric,

Did you manage to find a solutions to this problem because I have it also and I would like to know how to solve it.

Thanks

Hi Alexandru,

had the same problem. Found the solution in the ptc problem database (TPI 143667):

Clear all the Java cache on the client.

To clear client Java cache go to Start-> Settings->Control Panel->Java (Java Control Panel)

Under Temporary Internet Files -> Click Settings and then click Delete Files.

Make sure Applications and Applets check box is selected.

Alternative:

Use Browser upload instead of Applet upload by changing the upload preference from Preference

Manager

In my case only the alternative worked

Bye

We have the same problem but have deleted the temp Java files and set the Browser for uploading and still get the error. (We are using Java 1.6_22). When we reverted our Java back to 1.6_20 it seemed to work. Any suggestions to make it work with 22?

[TravisW.Reeder]

I was also having the same problem was on Java 1.6_23 reverted back to 1.6_07 and it fixed the problem; the other two suggestions did not work for me.

Unfortunately "getCacheDescriptor failed" is an overly and unnecessarily generic error report -- and can have many different and unrelated underlying causes. The error reporting here is being improved for future releases, but for the existing releases this makes it more difficult to be sure we're actually talking about the same problem.

All that said, if you see this failure for Java 6 Update 22 and higher and not for Java 6 Update 21 *and* other applets (e.g. the calendar applet) work from the same clients and for the same user, then I'm *beginning* to suspect that this is due to http://www.oracle.com/technetwork/java/javase/6u22releasenotes-176121.html#cve-2010-3560-6u22 -- even though the case I have seen does not mention "socket access restriction" in the logs as supposedly is the case if this is the issue. If this is due to this particular Java 6 Update 22 change, then it appears that the underlying issue is a DNS configuration such that the reverse lookup of the server IP address does not resolve to the server name -- and that this could then be worked around at the DNS level. The other workaround would appear to be sticking with Java 6 Update 21.

I have been having this same issue for some time and the way I have fixed it is to change the way I resolve my host mapping in the windows/system32/drivers/etc/host file to the Windchill system

I originally had the mapping like so:-

10.199.76.55 mgreenhalgh mgreenhalgh.ptcnet.ptc.com

chnaging the order fixed the issue e.g.

10.99.76.55 mgreenhalgh.ptcnet.ptc.com mgreenhalgh

I'd forgotten all about this thread of discussion. A patch has long since been made available for the issue where this message occurs only with Java 6 Update 22 and higher, but not with older Java Plug-In versions. It works around the issue introduced by Java 6 Update 22. As I'm not in technical support, I don't know the patch number/id, nor whether this has been made generally available for download or whether you have to request it for a specific version/MOR branch.

I did this setting and it works -> Preference Manager -> Attachments -> File Upload Mechanism >>> Use browser

But before that i clear the java cahce and Internet explorer temp file that time it not works...

[HugoHermans]

We solved this problem by editing the host file:

xxx.xxx.xxx.xxx pdmserver pdmserver.company.local gave this problem

xxx.xxx.xxx.xxx pdmserver.company.local pdmserver solved this problem

Regards, Hugo.

We solved this problem by disabling the Java Plug-In under the Advanced tab on the Java Control Panel.

Hugo's solution also works.

[Uthayan]

Try installing JAVA in drives other than C: will also fix up. Kindly let me know

[jessh]

Or you could figure out what patch you need from technical support -- as the Java Plug-In security changes which caused this issue have been worked around in the latest available patches.

[pmenezes]

Hugo's solution worked just fine.
