Issue/Introduction
When attempting to access XCOM Control center on a specific LPAR this screen pops up:
This page isn’t working
ii.iii.ii.iii sent an invalid response. ERR_INVALID_HTTP_RESPONSE
There are no messages in XCOMLOG or on syslog. Any suggestions on where to start looking ?
Environment
Release : 12.0
Component : CA XCOM Data Transport for z/OS
Resolution
Check that you have everything in place to use the Control Center with your LPAR:
Ensure that the 2 fixes related to Control Center are applied. SO13599 & SO10939
Make sure to have a valid qualifier resource name for parameter CC_RESOURCE in your CONFIG member for that XCOM task. The userid needs at least READ access to the resource.
Make sure that the URL you are using to get to Control Center on your LPAR has the correct IP and Port. Here is how the URL should look:
http://ipaddr:port/ControlCenter
In this case specifying a valid qualifier resource name for parameter CC_RESOURCE resolved the problem.
Make sure that your workstation has access to Internet
The page returned by Control Center uses Google Chart API to format the presented results which requires connectivity with the servers at Google. Note that, for this reason, Control center may not be used within a closed intranet which doesn't allow access to the public network.
Additional Information
If all of the above is correct and you continue to have a problem, then make sure to turn on the XCOM trace by issuing command /f xcomstc,TRACE,*. Reproduce the problem and raise a case with XCOM support providing the complete output of the XCOM task in question and trace. Make sure to turn off the XCOM trace using command /f xcomstc,NOTRACE,*.
