This error occurs when the CUCM web server no longer responds. It may happen without prior notice and it can be a pain in the a**.
HTTP Status 404 – /ccmadmin/showHome.do
If you are running CUCM in Vmware and you’ve just installed CUCM, I highly recommend you take a snapshot, because it is possible that you will revert the image back to a previous point.
Otherwise, here are the only options you’ve got:
- wait until the web server gets back online
- restart the web server from CLI.
I’ll assume you are impatient so you choose option 2
By the way, to display the list of Cisco services in CLI, do a “utils service list” or better “utils service list page”, which allows you to browse the services page by page, by pressing the space bar.
The web server service is called Cisco Tomcat. Sometimes you think Tomcat is started but it is playing tricks in the background. To restart it anyway: “utils service restart Cisco Tomcat”, exactly like that, case sensitive.
