Runtime Error Overide

Hi All

 

 

I've just experienced this error;

 

 

TCL error: Rule irule_all_blah_blah - can't read "::HOSTS_CLIENT1": no such variable while executing "matchclass [IP::client_addr] equals $::HOSTS_CLIENT1"

 

 

I know why it happened, I wrongly deleted the Data Group HOSTS_CLIENT1.

 

 

However, the irule in question (and many others) deals with a great deal of incoming traffic for multiple clients. This error stops the iRule running entirely, affecting all the clients. Is there any way to have this error ignored/keep the irule running?

 

 

And please don't say "split the irule per client," I'd have hundreds, hardly an enterprise grade approach.

 

 

Thanks in advance.

    Add error checking for each variable you use so the condition is checked only if there is a value. if exists ...

    can you be more explicit of how this is done, do you use a "catch"?

    Use catch when evaluating commands, use info exists when evaluating variables. Check out this thread:
