Hi Rajesh,
I apologize for the broken links. Recently the way we create and index knowledge articles has changed. This allows CA to create and index KBs in Google and support.ca.com more quickly. Sadly, this broke the links to the older "TEC" and all the URLs changed. We are working to correct all the links but for now I recommend searching on the title. Here is some information on how to best search.
This original "Tech Tip" was posted in 2016 so it is also possible some of these KBs have been retired (new versions, changes in functionality, added to documentation). If you have any trouble please let me know and I will be happy to help find any KB. Also, feel free to open new community questions. Thank you.
Knowledge Base articles
Another great resource is Knowledge Base articles. Anytime A CA Support engineer gets a call from a customer, they turn the outcome into a knowledge base article. As a CA customer, you have access to tens of thousands of these articles that could cover anything from an error code to . Check these out if you ever get stumped.
You can search for our Knowledge Base articles via our support portal OR from Google
https://support.ca.com
Searching support.ca.com
Search on the exact error. This could be an error from the UI or from your logs.
Support.ca.com is indexed by Google. When searching, please enter the exact error in the search bar. Your logs state “Failed to activate connector on proxy”. Enter this in the search field. This will yield a community post on the topic and a knowledge article on how to resolve the issue.
