Monitoring a CSS11503 sticky decision

Hi everybody,
we want to see and log (best would be to syslog) why the CSS takes a loadbalancing decision on stickiness. Is this possible and how should this be configured?
Our current problem is the following. We got a CSS11503 pair in box redundancy. They are loadbalancing https traffic to two SUN iPlanet instances using SSLv3. The rule is the following:
content https
protocol tcp
port 443
application ssl
balance aca
add service service1_https
add service service2_https
vip address 10.1.1.1
advanced-balance ssl
active
what we see is that some client gets forwarded to the second server during a session although it was directed to the first one before. And this leads to an 'authorization required' error in the client application. We can trace this in the iPlanet logs.
When using src-sticky, everything works fine, so this leads to the conclusion that it has to do with SSL loadbalancing.
Of course the application guys now blame the CSS for not working correctly, but I think (as a CSS guy) that the application is doing something wrong. So, I need to trace the sticky decision on the CSS.
Any ideas are welcome.

Hi Alex,
(I'm a CSS guy too!)
Have you investigated the actual SSL session ID's being used for that particular client when this error occurs?
We had a problem with very similar symptoms and had to use a Sniffer in order to find the root cause.
Our servers (I think they were IPlanet too, running on Linux) were not handling the SSL session-id "re-use" option properly. They were instead providing a bran new SSL session-id each time the client would send a SSL "re-negotiation handshake" (I'm not sure about terminology here!). In our case, we saw this happenning every 90 seconds, causing the clients to bounce from server to server because the CSS would not find a match in its SSL-sticky table and load-balancing would therefore take effect and cause the client to end up on a different server (similar to what you are reporting).
Unfortunately, in our case (also) we were unable to resolve this server issue and we resorted to src-sticky.
Good luck!

CSS11503- Sticky-cookie not working as expected

Hi I have a CSS11503 providing load balancing for an application. There are two servers to be load balanced. The CSS5-SSL-C-K9 hardware SSL installed on it.
I have configured the following services and css
service RESWINCOBBTAPP1_HTTP
keepalive uri "/webapps/portal/frameset.jsp"

balance leastconn
application ssl
url "/*"
port 443
protocol tcp
advanced-balance ssl
primarySorryServer SORRY
vip address 192.168.86.215
active
The problem are
1> When clients access the vip address on port 80 the css changes the port to 443. This is a default behavior but I want clients keep the connection on port 80, What do I need to change on CSS ?
2> When one of the server isn't available the client should move to the next available server and If the next server isn't available then client should move to SORRY page but in this case the clients are stuck to one(first) server. When I say the server isn't available that means the web page isn't available and server responds with HTTP error 500.
What do I need to change on CSS to move the client to next available server ?
I have similar configuration working in other part of the organization with some other application.
Thanks in advance

1/ this is most probably the server sending a redirect to https....not the css.
2/ if the connection is established with one server and this server then fails, the active connections will stay with that server. Only new connections will be sent to another server assuming the probe detected the server as down.

ACE 4710 HTTPS load balance configuration

Have two ACE 4710 in HA setup. We would like to setup HTTPS loadbalance(actually just a primary and standby configuration in the serverfarm). Initially this would be for Exchange OWA connections but may expand to more HTTPS connections later.
I know there are several ways to do SSL with the ACE( client, server, end-to-end). I am just wanting to know the easiest way to deploy this? Is a certificate always needed on the ACE for each connection? In HA mode would a certificate be needed for both or does it replicate in some way to the other ACE?
Any configuration examples would be helpful.
Thanks.

IF you terminate SSL on the ACE you need certificates and key on ace in the context in which you are doing the termination. The certs and keys need to be installed on the active and standby (manually unless using anm to manage).
when speaking of SSL
SSL termination refers to ace terminating SSL and sending to server as clear text
end to end - ACE terminates SSL (to look into payload to make a loadbalance decision or sticky decision) and then re-encrypts to the server, so to the client ACE is an ssl server and to the server the ace is an ssl client.
You can find some config examples at

Lbplugin not passing pages that end in .html through

Hi,
We are running SunOne 7.0 U2 webserver with the installed lbplugin for SUN Appserver (Glassfish). I've set up the loadbalancer.xml to pass the context root through to the appserver cluster, but any page in the war file that ends in .html is not passing through, but throwing a 404 error. It looks like the web server is looking locally for the files. I've tried everything I can think of to force it, but not sure what else to do. All images, etc. come through fine - just files ending in .html don't.
I've made sure the plugin is at the top of the magnus.conf, the NameTrans directive is the first one in the server-obj.conf file, etc.
Thanks!

Thanks, tried that, but the same behavior persists. The log shows that the /ac2 path (weblogic) gave a 404 not found because it was handled by the JSP engine. Local JSPs work (this is with the ntrans-j2ee still in the default block).

Is this something possible in standard MDGF workflows. Can any one share the name of the workflow or do we need to build the custom workflow.

Hi Rajesh,
If your Change request work flow does not contains any deadline monitoring steps where you need to monitor the work flow decision tasks in users inbox then this can be accomplished by using BRF.
Check link:

And if you have deadline monitoring steps then you can create a custom workflow using events and tasks.
Please let me know if you need any more details.

CSS and stickness

Hi all,
          I have a question about WL8.1 clustering and CSS loadbalancing. I hope to get some answers here!
          Environment: WLS8.1 SP5, Solaris, Cisco CSS11500, URL rewriting.
          Environment setup: We have 2 boxes hosting the WL cluster. We don't have a web farm in front. We only have Cisco CSS to perform loadbalancing and stickiness. Our application does not support coockies.
          My question is: Does CSS really care about primary and secondary servers? From what I have understood, if we use a h/w loadbalancer like Cisco CSS, we can configure it do make sticky decisions based on "jsessionid" in the URL (since we use URL rewriting) and the CSS forwards client requests to app servers based on their IP addresses? I guess if we were to use the plug-in, then it looks for primary server id to stick to the server?
          In our our case, we need to have the CSS look for "jsessionid" and not prmary server id. Please correct me if I am wrong.

There is something up I noticed it too - the work around I'm using at the moment is to split classes with the same tag into separate CSS and use @import in the main CSS file.
For instance, suppose i have CSS for body and then body.myClass - Safari ignores "myClass" when specified unless it's saved into a separate CSS file.
I first noticed this behaviour in 10.4.4

Escalation from approver to manager using organizational plan.

Hi all,
I have to escalate the the User decision step to the manager if the approver does not respond to the users request in 3 days. The employee, approver and manager Hierarchy is maintained in the oraganizational plan.
I am able to esacalate to the approver based on the employee based rule '168'.
Now how to escalate it to manager if the approver has not responded in 3 days.
Regards,
Gautham P

Hi Gautham,
You will need to setup a modelled deadline monitoring on the user decision step.
The deadline time can be set as a fixed value. For example 3+ days from creation of the step, or as a calculated value stored in the workflow container.
Depending on the requirements you may need to
1) Remove the User decision from the current recipient, and reassign to the manager, and/or
2) Just tell the manager that the recipient is not doing their job by sending a email.
If possible check if the person assigned is on leave by checking the associated HR records provided they are available. That way you can tell the manager that XX is on leave until DD.MMM.YYYY and has forgotten to forward their workflows/emails.
Kind Regards

Email notification - User decision - Deadline monitoring

Hi Experts,
My requirement is to forward workitem if there is no response from an approver for 6 days. I did this using deadline monitoring for 6 days in Latest End tab for user decision. But, daily i need to send reminder email notification if the workitem is pending for approver's response. Please suggest me in doing this.
Thanks in Advance,
Siva Sankar.

Hi Gurprit,
I've created a user decision with 6 days deadline in Latest End tab. When deadline occurs, i'm obsoleting the workitem from approver's inbox and in deadline outcome, i'm just reading next level manager's details. at the end i'm checking whether decision received from approver or not. if not, i'm sending the workoitem to next manager using loop step. This is working fine. But where to implement the logic to send reminder emails.
Thanks,
Siva Sankar.

Photoshop is a problem - "sticky" tools with external monitor

Hello!
When working in Photoshop is a problem - "sticky" tools. For example: working tool "Healing brush tool" we stifle alt and select the area and then release the Alt key and the target remains in the form of a cursor unstrument not be returned. The same problem with navigation for example, pinching the "space" appears "hand", which also remains.

Monitor decision!!!

Hi,
I am am looking to buy two new displays for my G5. I frequently use Final Cut Studio, so colour reproduction is fairly high up on my agenda. I have been quoted a very good price on the 'Dell Ultrasharp 2407WFP 24" Widescreen LCD Monitor'
http://accessories.euro.dell.com/sna/productdetail.aspx?c=uk&l=en&s=bsd&cs=ukbsd t1&sku=104716
Would this be a good display for my needs?
Will my ATI Radeon 9600 Pro (details below) be able to cope:
Chipset Model: ATY,RV350
Type: Display
Bus: AGP
Slot: SLOT-1
VRAM (Total): 64 MB
Vendor: ATI (0x1002)
Device ID: 0x4150
Revision ID: 0x0000
ROM Revision: 113-A13601-126
Any help and advice would be gratefully appreciated.
Thank you in advance.

On the retina macbook pro the UI is draw at 2x the "working resolution". Set to "native" on the 15" the UI, text, and images in some applications (safari and other web browsers, preview, etc...) are drawn at 2x. The same size as they would be on the non retina 1440x900 screen. Images in pro graphics applications (Adobe Photoshop, Lightroom, Premiere, PhaseOne Capture1, etc...) are drawn at the native resolution of 2880x1800. The application UI is drawn at 2x. Scaled resolutions are 1024 x 640, 1280 x 800, 1440 x 900, 1680 x 1050 and 1920 x 1200. The screen resolution is sampled to 2x these resolutions then scaled to the native resolution. UI elements are drawn as they would be at 1024 x 640, 1280 x 800, 1440 x 900, 1680 x 1050 and 1920 x 1200. Images in pro apps at 2x those resolutions. My last macbook pro had the "high res" 1680x1050 screen. I run my retina macbook pro at the same effective resolution with the plus one setting. It can be confusing that different applications display images at either 2x or "native" size. UI is always 2x. Photoshop displays images as if the screen is 3360x2100.
Hope this helps.

Deadline Monitoring for Decision

HI all,
I have taken a Decision Step in my workflow and on Latest End Tab specified 1 minute and in Action as Modeled.and specied the step number which i want to execute after deadline is missed.
The problem is After 1 Minute it is not going to that step.and Decision Step is in Process state in INBOX after 1 Minute.
and what is the use of PROCESSING OBSOLETE on OUTCOME TAB.and what is the role of PROCESS CONTROL?
Thanks and Regards,
Arpita

Hi,
I have specified deadline of 5 minutes and modeled branch and in the Outcome tab i have specified the Step number which i want to branch to after deadline is reached...and added one process control in modeled branch to set the WORKIITEM to absolute.
but the problem is after deadline is reached it is not branching to one i have specified in Outcome tab....In Log in Result tab it is showing PROCESSING ABSOLUTE but it is continue with next step not the one which is specified in OUTCOME tab.
Regards,
Arpita

Application Sudo listed in Activity Monitor - Is this a default app that should be running?

First Question:        Do other MBP users have an application Sudo listed in Activity Monitor from start up of their mac or with typical use?
Second Question:   If you have Sudo process listed in your Activity Monitor, do you also use an Huawei USB wireless modem?
Third Question:       For those experienced in relevant coding domains and given the more technical details below - your thoughts?
(Technical)
Using MBP Retina, mid 2012, OSX 10.8.4
I understand sudo is a unix root level access command.
I have used Terminal and become familiar with some basic unix commands, including using the sudo command in very limited single action command circumstances. I have not used Terminal for many weeks, and the sudo command probably twice several months ago.
Sudo showing in Activity Monitor as an active process is to my understanding an entirely different situation to it being used in Terminal. It appears the sudo process is being activated by some other application or process not of my direct use or actions.
I remain a little concerned about this in view of the purchase of this particular MBP. It has a story to it. I was told this MBP was available as new on discount as it had been purchased by a man for his wife, the wife then left him, and subsequently he returned it unused to the store.   I was aware that there was a slim risk the laptop had been used for some other activities, and returned so any come back comes back to the new owner.
I noted later with use that the MBP lower keys were sticky as if something has been spilt on them, so I do wonder if the laptop was previously used, then wiped, in which case the story presented to the retailer is likely not true and a more concerning scenario becomes possible.
All the same, I felt a clean install should remove any risk. The MBP arrived in standard ready to set up and go mode, so OS loaded but no activation. So it seemed a clean install to me.   I did not wipe the HD and do a fresh OS install from scratch. A decision I now regret.
Some months after using this new MBP, my concerns were raised when I had one day of inexplicable internet usage on a wireless internet connection. Not only did the level of data upload and data load, about 4 GB out of 20 GB for the month not make sense with actual usage, but also the MBP system logs did not tally with the internet providers accounting of usage on that day. There have been two or three other anomalies in usage since. The internet service provider reimbursed me on my evidence of OSX system logs. Not sure if the service provider has people joy riding other users accounts or something suss this end was going on. Never resolved. The ISP was not exactly forthcoming, and I had to press hard to get some collaboration on resolve the anomaly of unexplained data usage.
On the less suspicious side, the existence of this sudo program tracked down as in part coming from the install software from a Huawei modem provided by my internet provider. However, while widely used and therefore likely not a security risk, I still feel need for some better explanation and resolution of the persistent sudo process.
I have inquired to Apple Support about this sudo app running, and it apparently was not seen as an issue of concern by the front line support staff. I took up some further concerns with them but checks indicate no issues of concern with the MBP from their assessment. I trusted that as fairly likely a definitive view, and so left the questions and anomalies as unexplained but harmless.
It is now several months later and I still find the existence of sudo as a running application or process in Activity Monitor troubling, and decided to try and resolve once again how typical and for what reason it is active on my MBP. Which brings us to this post.
I have again spent a few hours searching on Google and Apple Support Forums.   All search results I find relate to the use of sudo as a unix command in Terminal to resolve a problem. I can not find any indication of sudo as an app being open routinely in Activity Monitor with or without Terminal being opened or used.
The only way I can think of to resolve if this is unusal or not is to get on this forum and ask the first two questions at the top of this post.
More technical details follow.
For some more technically minded the details may be of interest, hence below here I have added details for further comment.   I am hoping some MBP users on this forum may also be coders, and hence have some idea of the internal mac coding environment. Enough to shed some light on this situation.
As mentioned, I think the sudo Activity Monitor may originate from the running of the Internet Providers USB Wireless Modem and software (Huawei E 169? modem). The USB modem has the install software on it. You install that software on your HD as an application.
On this USB Wireless Modem front I have done some checking.
Killing sudo in Activity Monitor does not stop an internet connection mid session.
When the USB modem is removed, the sudo process remains running and listed in Activity Monitor.
If I remove the Modem icon, unplug modem, close all apps, restart without the modem connected, the sudo process is still loaded and running in Activity Monitor.
Months ago on a previous check if I deleted (uninstalled) the modem software, removed associated start up files installed by the modem installation, took out the USB Modem and did a restart, there was no return of the sudo process in Activity Monitor. When the modem software was reinstalled or the start up files restored directly, the sudo process returns to Activity Monitor. One of the software bits installed in start up files calls sudo (or so it appears having a peak in BBedit at the files.)
This seems to fairly much establish the source of the sudo application. However it does not resolve why it needs to be open all the time, and if this is unique to this modem, my modem, modems in general, or if permanent running sudo processes are fairly 'normal' in general. Since sudo is a root level access process, I do feel a little concerned of the situation.   Let's say the sudo process is needed to initiate the modem under some justification. Does the sudo process in remaining running permanently from there on, with or without the USB modem connected leave an open access way and vulnerability that can or is used later?   i do not know enough of the coding level architecture to form a view.   Still, seeing a permanent sudo process operating does niggle by sense of suspicion.    Hence, I continue to raise this issue and ask the questions I do.
In Activity Monitor:
sudo as a process when running is not very active.
Real Mem 8 KB, Virtual Mem 9.4 MB, Sent Msgs 75, Rcved Mesgs 26, Ports 25, Intel (64 bit).
The sudo process:
Using Sample Process in Activity Monitor:   sudo appears to be a running of the actual sudo command from within the unix command files.
Path:            /usr/bin/sudo (Master Library, not the one in the User files)
Load Address:    (removed)
Identifier:      sudo
Version:         ??? (???)
Code Type:       X86-64 (Native)
Parent Process: launchd [1]
Call graph
2nd line is 2656 start (in libdyld.dylib) + 1 [(removed)]
Binary Images:
Includes reference to lots of .dylib files. eg libcache.dylib, libquarantine.dylib, libremovefile.dylib, libcompiler_rt.dylib, libcorecrypto.dylib
The parent process is launchd[1]
Process:         launchd [1]
Path:            /sbin/launchd
Load Address:    (removed)
Identifier:      launchd
Version:         ??? (???)
Code Type:       X86-64 (Native)
Parent Process: ??? [Unknown]
It seems all of the activity of launchd[1] is from the sudo process.
Again reference to .dylib files as captured in call graph and Binary images.
I hope the details are valued by someone with an interest to assist with resolving concerns.

Thanks,
I usually use the OS connection option. So as you suggest, connect without the ISP connection software. Doing so does not by-pass the sudo command being active in Activity Monitor however.
On reading my post I see my failure to link the concerns of the laptop purchase with the sudo and modem. My thought here is of an intersection of known vulnerability with this widely used modem/software (via permanent sudo process activated) and that vulnerability then being known and utilised by another party(s).
I am pursuing the issue in part with consideration to a broader possible issue of vulnerability.
Thanks again for your thoughts and suggestions. Valued.

How do I get my Macbook Pro 15" to run dual monitor setup with Dual Link DVI outputs

I own have two 27" 2560x1440 WQHD LED IPS Computer monitors and have been trying to get them to work with my macbook pro 15" w retina for over a month now. I have purchased multiple products and nothing has worked. The big problem is that the only input that the monitors have is a Dual Link DVI input. The closest that i have gotten to getting them to work was this morning when I bought 2 Mini Display Port to Dual Link DVI Adapters for $99 a peice. Below is a link
http://store.apple.com/us/product/MB571Z/A/mini-displayport-to-dual-link-dvi-ada pter?afid=p219%7CGOUS&cid=AOS-US-KWG-PLA
Problem is that when I hook them up, I still only get a picture on one of the screens. Also, it requires you to plug into a mini Display port and USB port which takes up all of the space for me to run any othe peripherals. Though it has a built in USB port, when I plug my apple keybaord into it, I get an saying "USB Device Needs power, connect "keyboard Hub" to power or usb port on this mac"
I have looked everywhere for a docking station that would satisfy my needs, however, it does not exist. I use my macbook as my main office computer and take it home with me every night. I switched from the lenovo thinkpad to the macbook and have been satsified with my decision except for the fact that i cannot connect my monitors to it.
Please help!

Yes, that would work, however it would cost me $2000 for the monitors.
