JDE (JD Edwards) Ram Cache

Hi,

 

 

Has anyone configured Ram Cache for JD Edwards EnterpriseOne?

 

 

I have followed the documents in the F5 documentation area which says to basically use the default settings under wan optimization when using that though I find that the Menus in JDE freeze, as well as some of the applications in JDE appear to stay open when you log out and log back in.

 

 

I have tried only doing inclusion of the following:

image/jpeg

 

 

Maybe if i said do not cache anything unless in Inclusions?

 

 

Anyone else have settings they could recommend?

 

 

Thanks

 

 

Mark

    Hi mrg767,

    When you enable RAM Cache on an HTTP Profile, it works in combination with an iRule (usually), so that you can enable / disable inclusion based on whatever criteria you configure. If you do not control it with an iRule it will cache virtually everything by default.

    I would suggest including an iRule that first does CACHE::disable and then does some type of inspection to determine when to enable / include things into it.

    Something like this: 

    
when HTTP_REQUEST {
CACHE::disable
if { [string tolower [HTTP::uri]] contains "image" } {
CACHE::enable
}
}

    On a side note, you can see what is in RAM Cache from the command line (make sure you are in the correct Partition to run this):

    Show all HTTP Profiles (in the Partition you are in) that utilize ramcache.

    b profile http all ramcache show

    This command will override the default amount of entries dumped from the ramcache.

    b profile http (http.profile.name) ramcache entry max response 10000 show

    Hope this helps.
