[Where/How] to use OneConnect for permanent connection?

Guys, I've been trying to get F5 to setup a permanent connection using OneConnect to a real server but couldn't make it work.

So, here's what I have in my setup (all in Lab):

Virtual Server: 111.111.111.111
No default pool member, No persistence profile.

I do a pool redirection using irule, whether it's going to pool A or pool B (different application).

Now the Pool A application team needs this connection to be in permanent connection.

So in pool A node member consists of 192.168.13.250:20000.

I've tried using OneConnect profile in virtual server 111.111.111.111 but to no avail.

I do a tcpdump and see that F5 is actually sending a Reset flag at the end of connection instead of making it permanent for subsequent traffic to use:

14:41:33.166478 IP 192.168.1.100.56678 > 192.168.13.250.20000: R 105:105(0) ack 308 win 4687

Being mindful that all these are SSL packets.

Is there anyway to make this OneConnect works? Or am I missing something?

Thanks.

Recommendations at the end also states:

"The OneConnect profile may be used with any TCP protocol, but only when applied to virtual servers that process simple request/response protocols where transaction boundaries are explicitly obvious, such as those in which each request and each response is contained within a single packet."

However I've confirmed that it's not working for my environment. I took out oneconnect profile, and it works the same.

Anyone have more ideas on how to establish a permanent connection to a pool? Appreciate it.

Cheers.

you are using irule to detach serverside connection, aren't you?

  Hey nitass, I tried that. That didn't work too. In order for me to have a permanent connection to the pool, I thought I should have it disable? eg: ONECONNECT::detach disable

  i think it should be LB::detach because you want to detach serverside connection (make it reusable). have you tried?

  I haven't tried LB::detach So after I use LB::detach, do I use ONECONNECT:reuse enable ?
