Detailed information for "Maximum Retries" in Route-Assertion

  • 1.  Detailed information for "Maximum Retries" in Route-Assertion

    Posted Mar 18, 2019 10:10 AM

    Hi,

    CA docops only provides the following Information:

    The Maximum Retries defines the maximum number of attempts, in addition to the initial attempt, to establish a TCP Connection.

     

    But under which conditions are these retries occuring?

    For me this would mean, if a TCP-connection can NOT be established:

    - Either due to a TCP-timeout

    - Or due to a connection reset

    Any other issues are not on TCP-level anymore (like SSL-handshake failure or Read-Timeout).

    I tested the first scenario with a non-reachable IP-address and started a tcpdump in parallel. I only see SYN-packets until the TCP-timeout is reached and an error is thrown. But I don't see any retries afterwards.

    The second scenario is currently hard for me to simulate.

    And besides this, via which property and where can I change the System Default value (which is recommended to be 0 instead of 3)?

    Thank you!

     

    Ciao Stefan

    Hi Stefan,

    there is actually no option to change the default value at this point. Please see

    Add cluster-wide property to set default value of the Maximum Retries setting in Route assertions 

    and comment and vote to get this changed...

     

    When it comes to the conditions, my understanding was the same as your (TCP timeout or connection reset). But I haven't been able to test this myself.
