Problem with Links within SIM

[Dietmar Krause_1]

Hi,

we are running HP SIM 4.1 (SP1 with SP26191 on DL360G3 with W2K) for a couple of months now but recently the device links (for example: when you open the list of servers with minor problems and click the name of the server to get to the page with the detailed infos on this server) do not work anymore. When you click on it, the browser obviously does something (mouse pointer changes, the progress bar moves) but you stay on the page. Same on event list, but on this page you can view the event by clicking on the link but not the server.

I do not think this is an issue with the browser and / or java version on the client because the problem is on different client machines, with IE and Firefox and even directly on the SIM server.

The only thing done on the server was the installation of the current patches from Microsoft, but I am unable to find a connection to this problem by looking at the patch descriptions.

Can somebody help ?

Resolved this one by myself - nasty one

Finally took a look in the logs folder of SIM. Found the entries below in one of the files.

Hmm, something wrong with the database ? Lets look at the devices table. Strange, their is an entry with an empty name. Changed this to DUMMY, restartet SIM, works fine again ... :-)
