NimbostratusNeed a help migrating iRule from v9.4.8 to v 10.2.0
Hi All
I need a help to migrate iRule from v9.4.8 to 10.2.0. Current iRule is:
when RULE_INIT {
array set ::ARRAY_100 { }
each time Data Group List is updated with new products
this irule must be updated to load the new array
so change this timestamp below to update array in memory...
TIMESTAMP: 25/09/2008:10:00am
foreach item $::hurl_list_100 {
set index [findstr $item "" 0 ":"]
set data [findstr $item ":" 1 "\n"]
set LIST "$index $data"
log $LIST
set ::ARRAY_100($index) $data
}
}
when HTTP_REQUEST {
log "request "
set pool $::ARRAY_100([TCP::local_port])
log "Pool selected from array: $pool" use pool $pool
}
}
And is not initiated after upgrade to v10.2.0. I’m not very good it using array so I tried to change it to but still have a problems
when RULE_INIT {
array set ARRAY_100 { }
each time Data Group List is updated with new products
this irule must be updated to load the new array
so change this timestamp below to update array in memory...
TIMESTAMP: 02/09/2010:10:00am
foreach item hurl_list_100 {
set index [findstr $item "" 0 ":"]
set data [findstr $item ":" 1 "\n"]
set LIST "$index $data"
log $LIST set ARRAY_100($index) $data
}
}
when HTTP_REQUEST {
log "request "
set pool ARRAY_100([TCP::local_port])
log "Pool selected from array: $pool" use pool $pool
}
}
Any help is much appreciated
Thanks
- Hi Ignat,
It looks like you have an extra closing curly brace at line 21. Remove that and the rule should load fine. Don't forget to migrate the 'hurl_list_100' data group as well.
Best regards,
George 
Ignat_Vassilev1Thanks George
"hurl_list_100" data group is:
class hurl_list_100 {
"33001:EVOPBBR_100-POOL"
"33002:EVOPUXR_100-POOL"
}
so I don't see what has to be change in it for v10.2.0
Thanks
Ignat- Ignat_Vassilev1Hi Guys,
I decide to rewrite the iRule using class functionality with Array and it look like a better way to do it. Th eiRule and the data group class are bellow:
class hurl_list {
{
"1000" { "chris-pool2" }
"2000" { "chris-pool2" }
"4000" { "chris-pool1" }
"5000" { "chris-pool2" }
}
}
rule hurl-test {
when RULE_INIT {
each time Data Group List is updated with new products
this irule must be updated to load the new array
so change this timestamp below to update array in memory...
TIMESTAMP: 09/09/2010 09:00
if {[array exists ARRAY_100]}{
array unset ARRAY_100
}
for {set list 0} {$list < [class size hurl_list]} {incr list} {
log local0. "[class element -name $list hurl_list] -> [class element -value $list hurl_list]"
set index [class element -name $list hurl_list]
log local0.debug "Index = $index"
set data [class element -value $list hurl_list]
log local0.debug "Data = $data"
set ARRAY_100($index) $data
log local0.debug "\[array get ARRAY_100\]: [array get ARRAY_100]"
}
}
when HTTP_REQUEST {
log "request "
set pool $::ARRAY_100([TCP::local_port])
log "Pool selected from array: $pool"
pool $pool
}
}
The output of the login:
