universal persistence is not persistent?

Do you see duplicate persistence entries for all requests? Can you post the iRule which you're testing?

here you go:

 

 

pers_vs12 persistency profile assigned to VS

 

 

profile persist pers_vs12 {

 

defaults from universal

 

mode universal

 

mirror enable

 

timeout 3600

 

rule pers_vs12

 

}

 

 

 

rule pers_vs12 {

 

when HTTP_RESPONSE {

 

if { [HTTP::header exists "jsessionid"] } {

 

set jsess_resp [findstr [HTTP::header "jsessionid"] "!" 1 "!"]

 

if { $jsess_resp != "" } {

 

persist add uie $jsess_resp

 

}

 

}

 

}

 

 

 

This is irule i use for persistency:

 

 

when HTTP_REQUEST {

 

if { [HTTP::uri] starts_with "/app12" } {

 

set jsess [findstr [HTTP::uri] "!" 1 "?"]

 

if { $jsess != "" } {

 

HTTP::header insert X-WebLogic-Force-JVMID $jsess

 

persist universal $jsess

 

}

 

pool app12_dyn_be

 

}

 

}

 

 

Duplicates are for some requests:

 

 

Mode: universal Value: 1835648582

 

Virtual: 192.168.80.205:webcache Node: 172.28.252.150:9080 Age: 349sec

 

 

Mode: universal Value: 1835648582

 

Virtual: 192.168.80.205:webcache Node: 172.28.252.156:9201 Age: 216sec

 

 

 

If i persist by URL string part (1835648582 in this case), which node is used and why?

So you see multiple persistence records for the same value intermittently (not on every request)?

 

 

I'm not sure what would cause this. Here's a stab in the dark...

 

 

If you change the pers_vs12 rule's line from

 

 

persist add uie $jsess_resp

 

 

to

 

 

persist add uie $jsess_resp 3600

 

 

and then remove the universal persistence profile from the VIP, do you still see the issue occur?
