Cache server for SAP PLM

Hi,
Has anyone used any cache servers along with KPRO/content servers.
We have a multi site rollout and intend to limit the load on the content servers.
We have users located in three different continents, but there is going to be only one content server (in asia).
Now that we have decided to go with cache servers are we supposed to install these servers in all the three continents locally ??
regards
abhishek

Thanks Ulf,
So does that mean that KPRO server resides in headquarters while locally we will have cache servers.
Each of the cache servers connect to the central KPRO server.
Is this understanding correct ?
regards
abhishek

Using SAP Content Server for SAP E-Recruitment

Hi SAP Experts,
We are presently implementing SAP E-Recruitment using BSP services, We are successfully runnig with Whole E-recruitng cycle when we use SAP system DB as storgae for External Candidtes' Documents.
But, Our Client wants to have SAP Content Server to store all documents uploaded by External/Internal Candidates becuase client is worrying that if SAP system DB holds such huge data base of Resumes, it may slow down the performance of SAP System.
So, We need inputs from you suggesting whether is it feasible to use SAP Content server for SAP E-Recruitment Implementation. SAP no where suggests to Content server. So, we are in deliema to go for content server or not. If it is feasible to use Content server, pls provide me proper links or documents for reference.
Please give your valuable inputs,
Thanks & Regards,
Sudheer Kumar P

Hi Sudheer,
We are considering the same option. We are concerned about performance after all these documents are uploaded too. Did you install a content server? How did it go and was it difficult to set up with e-rec?
Thanks

How to start the file server for Agile PLM

when i try to add one attachment for an Item, i got the following error message:
The preferred file server http://agileserver:8080/Filemgr/AttachmentServlet for user : xxx is down
how to startup the file mgr?

Hi is this looks like a question for Agile A9.
For Agile A9 or Primavera questions, you can use Oracle Support, Support Communities, Yahoo Groups for Agile API or WRAU.
This forum is for Agile PLM for Process, which is part of the same Agile family but a different product.
Thanks.

Proxy / Cache server for flash content / videos / stream

hi there,
i've tried to search the web, but so far no straight answer...
we are looking to implement/deploy a proxy server to cache and then serve flash content (published in the internet), so we can reduce our internet bandwidth utilization. Windows Server 2008 has Windows Media Services which have a feature to cache windows media content or split live stream. (http://www.microsoft.com/windows/windowsmedia/howto/articles/cache_proxy.aspx)
is there a similar product to deal with flash content?
thanks in advance for all responses!

I'm more or less in the same boat. I've got the admin console
up. I am able to run the vodtest application locally pointing the
video file to rtmp://localhost/vod/sample.flv or using the server
name instead of localhost as in rtmp://mclmedia/vod/sample.flv
I can also load the html and swf file to my xp machine that
has access to the server via our internal network. (DNS isn't
configured yet) But the connectionFailed message appears when I try
to call the videos using rtmp://mclmedia/vod/sample.flv

IBM Virtual IO Server for SAP Production Application Servers

Hi.
We are planning to host SAP (AIX/Oracle) on a new IBM p-570. We want to install a LPAR for the DB/CI and 2 additional LPAR's for DI's. The problem is that we have to use Virtual Ethernet connections for the 2 DI's since we do not have physical network adapters for them. Will this be a SAP supported configuration or not, and why not?
Regards
Pieter
[email protected]

Hi Pieter,
your plan is totally feasible and supported by SAP.
You can use the VIO server to provide both Ethernet and I/O connections for all LPARs which do have have own physical adapters.
All specifics of micropartitioning and HW virtualization (like VIO) under AIX 5.3 and System p technology are supported. There are multiple SAP customers, who use this setup for their whole system environment.

Apt-cacher-ng : a cache server for... Pacman (and APT)

Hello !
I just adopt apt-cacher-ng on AUR, because I'm using it for APT (I use debootstrap and chrooted environments) and it help me saving a lot of bandwith (531Mb today).
So here is the package if you are insterested :
http://aur.archlinux.org/packages.php?ID=40662
I've seen in the main configuration file that it can be used for Archlinux. So I did it
I will share my configuration in this topic.
Configuration
The main file is /etc/apt-cacher-ng/acng.conf
I'm using apt-cacher-ng only on my laptop :
BindAddress: localhost
Here are some Remap lines for Debian repositories (including security) :
Remap-debrep: file:deb_mirror*.gz /debian ; file:backends_debian
Remap-debsec: /security ; http://ftp.fr.debian.org/debian-security
This is the line for Archlinux
Remap-alxrep: file:archlx_mirrors /archlinux ; file:backend_archlx # incomplete, please create this file or specify preferred mirrors here
Here is a very permissive addition to the VfilePattern regex to allow the *db files (needed for pacman -Sy)
VfilePattern = (^|.*?/)(Index|Packages\.bz2|Packages\.gz|Packages|Release|Release\.gpg|Sources\.bz2|Sources\.gz|Sources|release|index\.db-.*\.gz|Contents-[^/]*\.gz|pkglist[^/]*\.bz2|rclist[^/]*\.bz2|/meta-release[^/]*|Translation[^/]*\.bz2|.*\.db)$
Just put in the file /etc/apt-cacher-ng/backend_archlx your nearest mirror without the "$repo/os/$arch" part :
In my case :
echo http://mir.archlinux.fr/ > /etc/apt-cacher-ng/backend_archlx
Usage
You can now restart apt-cacher-ng
rc.d restart apt-cacher-ng
Here is your new /etc/pacman.d/mirrorlist !
Server = http://localhost:3142/archlinux/$repo/os/$arch
Just in case, here is a minimal /etc/apt/sources.list for Debian :
deb http://localhost:3142/debian squeeze main contrib
deb http://localhost:3142/security squeeze/updates main contrib
Reflector
If you want to use the very last synced archlinux repositories, with reflector, you can do something like that
rc.d stop apt-cacher-ng
reflector -p http -l 1 --sort rate | grep -o -e 'http://[^\$]*' > /etc/apt-cacher-ng/backend_archlx
rc.d start apt-cacher-ng

Hi, thx for info. Just checking with file:archlx_mirrors
that file needs to be created as well? Can I leave it
out and just have -> Remap-alxrep: /archlinux ; file:backend_archlx
I suppose I can just test it. I read the docs, but they are a bit confusing :-)
I'm not sure and I'm not a master of apt-cacher-ng Precise documentation is here :
http://www.unix-ag.uni-kl.de/~bloch/acn … tml#repmap
The file archlx_mirrors is in the package, and contains a list of mirrors.
The second part of Remap- line, TargetURLs, is optional.
Just try and give your results here please

Cache resetting for SAP BPC

Hello
I have an issue where we have restored SAP BPC back to 6th June 2008 backup, but when I login, I can view reports I created on 20th June 2008.
Would appreciate any help with locating
where the cache files are stored and any ideas why it's not updating?

For the instances where we've had to get support from SAP, we've backed up our AppSet and uploaded it to an FTP site where SAP then would download it.

Architectural Choice for accessing Coherence Cache Server

I am a newbie and have a coherence use-case question.
When accessing an independent coherence cache server from application code such as an EJB deployed in WLS, architecturally does one write up an entity which is then used as a sole point of
access to the resource (coherence cache server) for querying, adding, modifying entries or are the accesses to the coherence cache server split and spread among the application code.
For example,
1. I write an EJB (EJB 1) which recieves the request from other EJB's (EJB 2, EJB 3), EJB 1 runs requests from EJB2 and EJB 3 on the Coherence Cache Server and acts as the sole point of
contact to the resource.
2. EJB 2 and EJB 3 both run requests against the coherence cache server. No fixed entity in architecture repsonsible for interaction with Coherence Cache Server.
Which is more common ?

stevephe wrote:
Yes you could treat Coherence as a "pluggable" resource, just like a database. But that, just like in the case of a database, wouldn't boil it down to a single entity/interface. You'd treat Coherence as a "integration tier" resource that you'd "plumb in" just like you would a database, thus shielding your application's "domain" objects from integration-level concerns. That's how I've tiered our application, although we aren't inside a container like Weblogic/WebSphere/etc. The domain objects specify their persistence requirements via a multiplicity of interfaces; those interfaces have a number of implementations in the integration tier, one set of which just happens to be a Coherence set. You can use a "registry" approach to pick up the appropriate implementations (we use Spring injection.) Have a look at the Coherence book from Apress for more details.Apress? You mean Packt, don't you?

Cache Server DB

Dear Expert
DMS DB ( maxdb ) attach and de-attach work with cache server.
we have already implement Content Server few month back and now we need to install DMS cache server for Content server.
Our Content server grow up to 30 GB and we need to fill our Cache Server with the same.
My question is if take backup of Database CS server ( 30 gb) attach to Cacher server ( I mean attach and de-attach) will it work for cacahe sever same as CS server.
Regards

Hi,
You may need to install Cache Server like you did for content server using sapinst installer.
Refer SAP Note 216419 - Multilevel caching and content server
For cache server configuration.
Attach and Detach won't work in MaxDB. You may need to perform backup/restore which I feel won't be a good practise here.
