CSS 11503 - question on version

We're about to do an annual OS update to our CSS 11503, and I noticed that there are two current versions of WebNS, both released in the same month: 8.10.4.01 and 8.20.2.01. Could anyone outline for me the differences between the two (or point me to the right release notes)? I usually upgrade to the latest release, but having two at the same time is awfully confusing.
Thank you!

They are essentially the same.
We always port all fix to both of them.
Release notes are here :

CSS 11503 Users using a proxy

I currently have a CSS 11503 LB that I am using to balance 443 and 80 traffic and I have it working but my question is if a users are coming from a proxy should I continue to use Layer 3 LB technique? Also is it possible to see the real IP address instead of the IP of the proxy server?

the problem with proxy is if you use some form of stickyness like sticky src ip.
Since the src ip is always the proxy, you end up with all your traffic going to a single server.
If you are doing sticky src ip, I would suggest to use arrowpoint-cookie instead.
To see the real-ip you need your proxy to insert in the http header a 'x-forwarded-for' line with the client ip.
Your servers can then extract this value to determine the client ip.
On the CSS you won't be able to see the client-ip.

CSS 11503 does not ask confirmation

Hi,
Our CSS 11503 does not ask confirmation when I want to delete or add a service, owner or group.

Routing issue with CSS 11503

The senerio contains a PIX 515 E firewall,4507R Chassis switch and a CSS 11503. The servers in inside zone of the PIX is load balanced using a vip with default route specified in the CSS is the inside zone interface IP of the PIX
Now I would like to load balance the servers in the DMZ zone of the PIX with a separate vip(from DMZ zone) in the same CSS. Since the default route in CSS is towards the inside zone of the PIX, I am unable to see the load blanced pages from dmz. Is there any solution to load balance the servers of the 2 zones with 2 different vip's using a single css ?

The default behavior is to use the calling device's CSS for the redirected calls. In your case it sounds like you want to use the redirecting device's CSS. I haven't tried this myself but I believe you will need to change the following registry entry on your PGs. You will want to use option 2 (ROUTEADDRESS_SEARCH_SPACE).
HKEY_LOCAL_MACHINE\SOFTWARE\Cisco
Systems,Inc.\ICM\IPCCL\PG1B\PG\CurrentVersion\JGWS\jgw1\JGWData\Dynamic
"UseRouteAddressSearchSpace"=dword:00000000
- Used to control behavior on CTI Route Points for Route Selects.
UseRouteAddressSearchSpace can be to set 0, 1, or 2 where :
DEFAULT_SEARCH_SPACE = 0
CALLINGADDRESS_SEARCH_SPACE = 1
ROUTEADDRESS_SEARCH_SPACE = 2

CSS 11503 load-balancing with MS Print Servers

We are trying to load-balance print server connections between 2 MS print servers. When we try to connect to the print servers name, (\\PS01) or even the VIP address, we get a Path not found error. However, if we direct the path to the actual name or ip address of the print servers (not the VIP), we can view all the queues and connect/print to them. Is this possible to do on the CSS 11503? Thanks.

Global Cerificate on CSS 11503

Hi
I am planning to enable https for few web servers behind a CSS 11503. I have tested the functionality with the trial cert every thing works as desired.
Now I need to buy a certificate from Verisign to make it work in production.
At verisign they offer two different certs (Secure Site --40 bits encryption) and (Secure Site Pro -- 128 bit encryption).
1. Is this 128 bit cert a "global cert"? and I need to concatenate the "intermediate cert" and "server cert" to make it work?
2. If all my users are in USA then does it make sense to buy this 128 bit certificate?
3. Verisign website also asks for "server Platform" and cisco is not mentioned as an option (I can see other LB as F5 in the list). What should I select for the server Platform when I am requesting it for CSS 11503 (I have generated the CSR on CSS 11503).
Thanks in advance
Glenn

1.The guy who picked the phone at verisign had no clue.Verisign website says the following
Secure Site Certificate (40bit minimum)- SSL Certificates without SGC
To install your SSL Certificate, go to the instructions below for your server software. If your server is not listed or you need additional information, refer to your server documentation or contact your server vendor
Secure Site Pro Certificate(128bit minimum) - SSL Certificates with SGC
If you are installing an SSL Certificate with SGC, you need to copy an Intermediate CA Certificate before proceeding to the installation instructions for your server software.
2.My understanding was that 40 bit is minimum encryption level and only old browsers (exported ones) will us 40/56 bit ciphers. Other wise even with 40 bit certificate the new browsers will establish a 128 bit session.
Verisign says about their 40 bit certificate
"40-Bit to 256-Bit SSL Encryption Non-SGC SSL Certificates provide a minimum of 40-bit and up to 256-bit SSL encryption. Site visitors using certain older browsers and many Windows 2000 users will only receive 40- or 56-bit encryption unless they’re connecting to an SGC-enabled SSL Certificate"
I found a document on net in favor of buying 40 bit certs.

Routing non-TCP/UDP traffic while using FWLB on CSS 11503s

Hello all,
I've been tasked to setup up FWLB with CSS 11503's as shown below. The issue is that intranet workstations use VPN client software when connecting to certain sites through the Internet and other times they use http or https (for connection to different sites). Because no flow is setup for ipsec and ECMP uses per packet routing for non TCP/UDP traffic, I'm concerned that load balancing through the firewalls will occur on a per packet basis. If that is true, stateful inspection in the firewalls will block asymmetrical traffic flows.
Is my understanding correct? And, if so, is there a way to configure the CSS units to deal with this?
Thanks in advance.
(sorry for the dots in the drawing but the spaces kept getting deleted)
.| Internet |
..........|
.| CSS-outside |
.............|
........|...............|
.| FW1 |.....| FW2 |
.......|................|
............|
.| CSS-inside |
............|
.| Intranet |

for non-flowy traffic like IPSEC, we use a hash algorithm to decide where to send the traffic.
So, it's not per packet loadbalancing.
The same source/destination ip/port will always go to the same firewall.

Remove Health Care (keepalives) CSS 11503

Hi,
We normally distribute the load between two servers by checking if the server its active (using TCP 80), yesterday, we want to remove the Health Care (keepalives) due to a maintenance test, to sent the traffic direct to the server, but the service stop working.
We think we didn’t remove the health care properly, could anybody please help me to know hoe to remove it?
We are using CSS 11503, I’m adding the config.
Thanks

Installing an SSL certificate for a CSS 11503

I'm having the hardest time searching for clear instructions on how to request and install an SSL certificate for a CSS 11503 Content Switch. Can anyone help or point me in the right direction?
I'm also looking for instructions on how to replace an SSL certificate once it's been installed. Thanks!

Allen,
The portion of the configuration guide related to SSL certificates and keys can be found here:
http://cisco.com/en/US/products/hw/contnetw/ps792/products_configuration_guide_chapter09186a00801eea82.html#1422544
To replace an SSL certificate, you'll need to remove the current certificate and re-import/create the new one.

Cisco CSS 11503 Arrowpoint/Load Balance question

I am troubleshooting an issue with my 11503. I am running version 07.40.0.04. I have it configured as follows:
content upcadtoa-rule
    add service cadtoa-wls1-e0
    add service cadtoa-wls1-e1
    add service cadtoa-wls2-e0
    add service cadtoa-wls2-e1
    add service cadtoa-wls3-e0
    add service cadtoa-wls3-e1
    add service cadtoa-wls4-e0
    add service cadtoa-wls4-e1
    add service cadtoa-wls5-e0
    add service cadtoa-wls5-e1
    add service cadtoa-wls6-e0
    add service cadtoa-wls6-e1
    arrowpoint-cookie expiration 00:00:15:00
    protocol tcp
    port 8001
    advanced-balance arrowpoint-cookie
    redundant-index 2
    vip address 172.30.194.195 range 2
    arrowpoint-cookie name TOA
    active
However, the load-balancing across the servers does not seem to be doing much balancing. One of those servers is getting hit with 5 times as much traffic as another and another server is lucky to get a connection at all. With the cookie expiration set, one would think that this would all balance out over time.
I just came across this information from Cisco and I am wondering if it is relevant:
If you configure a balance or advanced-balance method on a content rule that requires the TCP protocol for Layer 5 (L5) spoofing, you should configure a default URL string, such as url "/*". The addition of the URL string forces the content rule to become an L5 rule and ensures L5 load balancing or stickiness. If you do not configure a default URL string, unexpected results can occur.
In the following configuration example, if you configure a Layer 3 (L3) content rule with an L5 balance method, the CSS performs L5 load balancing, but will reject UDP packets.
content testing
vip address 192.168.128.131
add service s1
balance url
active
The balance url method is an L5 load-balancing method in which the CSS must spoof the connection and examine the HTTP GET content request to perform load balancing. The CSS rejects the UDP packet sent to this rule because a UDP connection cannot be L5. Though the CSS allows this rule configuration, its expected behavior would be more clear if you promote the rule to L5 by configuring the url "/*" command.
In the next example, if you configure an L3 content rule with an L5 advanced-balance method, L5 stickiness will not work as expected.
content testing
vip address 192.168.128.131
add service s1
advanced-balance arrowpoint-cookie
active
The advanced-balance arrowpoint-cookie method causes the CSS to spoof the connection, however, the CSS still marks it as an L3 rule. Thus, the CSS does not insert the generated cookie and the rule defaults to L3 stickiness (sticky-srcip). You must configure a URL like url "/*" to promote this rule to L5, ensuring that L5 stickiness works as expected.
Thanks in advance for any help you can give. The thing is not down, it is just balancing strangely causing application performance issues.
James

Hey James,
You will need to suspend the content rule in order to add the url statement. This will cause a quick downtime until the content rule is activated again. I have shown below the commands to add the statement. Perhaps you can create your commands in a Notepad file, then paste them all in so they execute quickly to minimize your downtime:
content MY-SITE
    vip address 10.201.130.140
    port 80
    protocol tcp
    add service MY-SERVER
    active
CSS11503# config t
CSS11503(config)# owner TEST
CSS11503(config-owner[TEST])# content MY-SITE
CSS11503(config-owner-content[TEST-MY-SITE])# url "/*"
%% Attribute may not be modified on active rule
CSS11503(config-owner-content[TEST-MY-SITE])# suspend
CSS11503(config-owner-content[TEST-MY-SITE])# url "/*"
CSS11503(config-owner-content[TEST-MY-SITE])# active
CSS11503(config-owner-content[TEST-MY-SITE])# exit
CSS11503(config-owner[TEST])# exit
CSS11503(config)# exit
CSS11503# show run
content MY-SITE
    vip address 10.201.130.140
    add service MY-SERVER
    port 80
    protocol tcp
   url "/*"       <--------
    active
Hope this helps,

CSS 11503 adv-bal-stcky-srcip and failover question

From the documentation I have read about failover (when a service fails) it lists several loadbalancing types, but the advanced-balance-sticky-srcip is not one of them. Is it possible to configure failover linear or failover next when using adv-bal-stcky-srcip? The CSS is configured for a kal (type=tcp / port=8080), but does not do anything when the service does not respond the kal.

Let me add some clarity then. :) I am running PeopleSoft through the CSS (which is the reason for adv-bal sticky-srcip). I have two services in my content rule:
service pplsft-web1
ip 172.27.144.63
port 8080
kal tcp / 8080
service pplsft-web2
ip 172.27.144.63
port 8080
kal tcp / 8080
When the KAL fails and the service is marked down, what is the CSS supposed to do?...you can configure the failover of a a service (ie: failover linear or failover next). In all the docs I have read, I read that 'failover linear' and 'failover next' were for regular load balancing techniques (ie: domain, url, srcip, destip, domainhash and urlhash). Can I use it if I have the advanced-balance sticky-srcip load balancing command on the content?
Does that clarify any?
I did get an answer from TAC...by default, 'failover linear' is enabled. But what may be happening is that because of the sticky config, the user ip is still in the sticky table, which over-rides load balancing. I have to define the settings for "sticky serer down failover" to either 'balance' or 'reject' entries in the sticky table and any requests that come in.

Some questions on versioning and synchronizing metadata

Hy all!
I am quite new to warehousing and Oracle Warehouse Builder, and so i would have some questions regarding on some common issues. I would appriciate if you guys would who have experience in this domain to share some good practice knowledge :)
I am using OWB 10.2
So first of all i would like to know if you have some proposal of the way of versioning control and synchronizing projects between team memebers when working on a bigger project, team memebers that don't work on the same repository (cause i saw that OWB has an integrated multiuser support for handeling object locks and user sessions).
I saw that a way of migrating data from one place to a nother is using the import/export options integrated in OWB. This creates mdl files wich are some kind of "dumps" of the metadata informations, but the thing with these mdl files wich i don't think is a good way to synchronize is that first of all the .mdx and .xml files contained in the .mdl (wich is kind of a zip) contains many informations in it (like creation date, some timestamps, etc) wich are always updated when exporting, and if synchronizing these files maybee using CVS, we always will get differences between the files alltough they would contain the same thing, only timestamps changed.
Then a nother issue with this, is that we could have 2 alternatives: dump the whole project, wich is odd to have to synchronize a single file between users, especialy on a big project, then the orher way would be doing for each object from the project (each mapping, each table, etc) an separate .mdl filem then to synchronize each file of each object, wich will be unefficient on reimporting each file in part.
So please if you can share the way you work on a big project with many implementers with OWB, i would really appriciate.
A nother thing i would like to know is: is there a way to generate from an existing project (like one created with OWB) the OMB commands dump (maybee in a tcl script)? Cause i saw that the way the exeprienced users implement warehousing is using TCL with OMB language. I downloaded the example from oracle for warehouse project, and i saw that is entirely made from tcl scripts (so no mdl file involved). And this i think would be nice, to have the OMB commands generated from an existing projects.
I see this OWB projects like a database wich can be built up from only OMB commands and OWB a graphical tool to do this (same as constructing a database only from DDL commands or using SQL developer to do this), this is why i am asking about a way of dumping the OMB commands for creating an OWB project.
Please give me some advices, and correct me if i sad some dumb things :D but i really am new to warehousing and i would really appriciate if you guys with experience could share some informations.
Thank you verry much!

Depends. Having everyone working on the same project certainly simplifies things a lot regarding merging and is generally my preference. But I also recognize that some projects are complex enough that people wind up stepping on each other's toes if this is the case. In those cases, though, I try to minimize the issue of merging changes by having common structural objects (code libraries, tables, views, etc) retained in a single, strictly controlled, central project schema and having the developer's personal work areas reference them by synonym, thus being unable to alter them to the detriment of others.
If they want to change a common object then need to drop their synonym and make a local copy which they can alter, and then there is a managed process by which these get merged back into the main project schema.
This way any changes MUST go through a central schema, we can put processes in place to notify all of the team of any impending changes, and can also script updates across the team.
Every hour a script runs automatically that checks for dropped synonyms and notifies the project leader. It especially checks for two developers who have built local copies of the same object and notifies each that they need to coordinate with each other as they are risking a conflict. When a structural change is submitted back to the central shared schema, it is added to a batch that is installed at end of business and a list of those impending changes is circulated to the team along with impact analysis for dependencies. The install script updates the main schema, then also drops the local copy of the object in the developer's schema who made the change and re-establishes the synonym there to get back to status quo for the change monitoring. Finally, it then updates itself in all of the developer areas via OMBPlus. So, each morning the developers return to an updated and synched environment as far as the underlying structure.
This takes care of merging structural issues, and the management of the team should minimize other metadata merging by managing the worklist of who is to be working on a given mapping or process flow at a given time. Anyone found to be doing extraneous changes to a mapping or process flow when it is not in their job queue without getting pre-approval will be spoken to VERY firmly as this is counter to policy. And yes, OWB objects such as mappings are then also coordinated to the central project via import/export. OMBplus scripts also propogate these changes daily across the team as well.
Yep, there is a whole lot of scripting involved to get set up.... but it saves a ton of time merging things and solvinv conflicts down the road.
