Sticky resource issue

I receive error message "Error: sticky resource not available" after configuring "ACE/Admin(config)# sticky ip-netmask 255.255.255.255 address source STICKY_FARM" in Admin context. There is no other context on the ACE and I intend to use all sticky resources in Admin context. How I can accomplish that?

Hi Thorr,
Before you can use stickiness, you need to assign some sticky resources to the context where you want stickiness to be used.
For more details, please, check the link below:

Sticky resource not available - ACE Module

hi,
I am getting the below error on defining stickiness. Please assist.
switch/Admin(config)# sticky ip-netmask 255.255.255.255 address both ACE-CKH-STICKY
Error: sticky resource not available
Thanks.

Note The syslog message statistics do not include the syslogs generated from the dataplane when you enable the logging of connection setup and teardown syslog messages through the logging fastpath command.
â¢regexp-Limits the amount of regular expression memory.
â¢sticky-Limits the number of entries in the sticky table. You must configure a minimum value for sticky to allocate resources for sticky entries, because the sticky software receives no resources under the unlimited setting.
â¢xlates-Limits the number of network and port address translations entries.
â¢minimum number-Specifies the lowest acceptable value. Enter an integer from 0.00 to 100.00 percent (two-decimal places of granularity). The number argument specifies a percentage value for all contexts that are members of the class. When used with the rate keyword, the number argument specifies a value per second.
â¢maximum {equal-to-min | unlimited}-Specifies the maximum resource value: either the same as the minimum value or no limit.
Note The limit that you set for individual resources when you use the limit-resource command overrides the limit that you set for all resources when you use the limit-resource all command.
If you lower the limits for one context (context A) in order to increase the limits of another context (context B), you may experience a delay in the configuration change because the ACE will not lower the limits of context A until the resources are no longer being used by the context.
For example, to allocate 20 percent of all resources (minimum and maximum) to all member contexts of the resource class, enter:
(config-resource)# limit-resource all minimum 20% maximum equal-to-min

Sticky Resource Not Available when setting up sticky http-cookie

When I try to configure the sticky:
(config)# sticky http-cookie ACE-COOKIE COOKIE-STICKY
I get the error:
sticky resource not available
An L7 policy has not yet been set upâ¦ could that be the reason for this error? Or, is it because I have not setup a class resource for the sticky cookie?

Syed,
I thought it resolved it, but it really didn't.
Added the resource-class in the Admin context:
resource-class any-available
limit-resource all minimum 0.00 maximum unlimited
limit-resource sticky minimum 35.00 maximum equal-to-min
no difference.

Sticky resource not available ?

I get the following error message then i try to configure sticky on an ACE:
Error: sticky resource not available
What is the problem ?
I have release "c6ace-t1k9-mz.A2_1_2.bin" and sticky should be supported.
ace-10/RGW_Front_servers(config)# sticky ip-netmask 255.255.255.255 address source RGW-FRONT
Error: sticky resource not available

Hi Ola,
By default sticky resources are not available. You need to go to the Admin context and define a new resource class with some stickiness. See Server LoadBalancing Guide Chapter 5 p8. For example:
resource-class RC1
limit-resource all minimum 0.00 maximum unlimited
limit-resource sticky minimum 10.00 maximum equal-to-min
Obviously the amount of sticky resource to allocate will depend on your application.
And then you need to make the context that needs stickiness a member of that resource class.
For example:
context Test
allocate-interface vlan 292-293
member RC1

BW system ran out of "session" = transaction SMGW; how to track down "resource" issues?

Hi SAP Experts,
we had on our SAP BW system the following situation:
We are having a week daily process chains, that is uploading data from our ECC system.
Once in a month, we are uploading from our APO/SCM system data from our BW system.
Parallel we are having also SAP PreCalculation Server (with three PreCalc instances) instances running. The PreCalc Server is running daily.
The landscape in short: (DB server = AIX/Oracle, App-Server = Linux, SAP System=7.01; PreCalc Server = Win2008/64)
This week when all was running at the same time, we faced problems, that log-on to SAP System via ABAP took a long time, same BEx Reports (some failed with Run Time errors).
From the landscape infrastructure we couldn’t detect any resource issues (we are having two application servers connected to the BW landscape).
What we saw from the system transactions (SM66, SM51, SM21, ST02, ST04, ST06N) the issue did not seem to be resource based, by network, database, amount of work processes etc.
But we noticed in transaction SMGW, that it seemed not possible for external programs, like a BEx reports or the PreCalc Server to connect with new session to the BW ABAP landscape.
The trace showed in SMGW:
* LOCATION    SAP-Gateway on host server / sapgw##
* ERROR       Conversation 01792797 not found
* TIME        Tue Jul 22 14:13:03 2014
* RELEASE     720
* COMPONENT   SAP-Gateway
* VERSION     2
* RC          728
* MODULE      gwxxconn.c
* LINE        971
* COUNTER     75240
In system log, database alert log, we could not find any dead locks reported or anything reported, that explained why, via the SMGW is was not possible to connect with new sessions.
We restarted the PreCalc Server and after clarifying with application team of APO/SCM we stop the process chain and than the system was back to “normal” operation.
Now the question is, if you faced similar issues and what the solution, or how you where able to track down the issue?
Thanks for your ideas.
Best regards
Carlos Behlau

Hi Alwina,
thank you for your help.
What I was able to is in SMGW, because the system was very slow, that some connection where "red".
I forgot to capture screenshots and now I am not able to recall the the status text.
It is there a way to find out, if we reach the "max" connection numbers, like parameter gw/max_conn 500, via ST03N or via SMGW or via some logs?
I checked the SMGW trace, but I am not able to identify via the trace in SMGW, if the failures happened now, because max. values of parameters have been reached or what the cause was/is.
What I meant:
All external programs, like SAP BW BEx Analyzer (Excel Reporting tool for BW) are connecting via RFC calls. Also SAP Pre-Calculation Server is using RFC calls to generate the reports and send them via E-mail.
Usually, I can see these connections in SMGW (goto => logon clients).
There I didn't noticed that we reach 500, when we had the problem.
Best regards
Carlos

HTTP sticky timeout issue in ACE .

Hi All ,
We are facing the dis connectivity issue in the the http session ( sticky configuration )
As per the customer requirement we configured the http sticky with the connection time out 60 min ( one hour ) .
But as per the test with the tool cookie manager , they identified as the http sessions are getting timed out in 20 to 30 minuits .
Please find the sticky configuration
sticky http-cookie FRONT_SESSION_ID TEST_FRONT
cookie insert
timeout 60
replicate sticky
serverfarm TEST_FRONT
We also did the http persistence as below .
parameter-map type http HTTP_Persistence_Rebalance
persistence-rebalance
Parameter-map : HTTP_Persistence_Rebalance
Description : -
Type : http
    server-side connection reuse       : disabled
    case-insensitive parsing           : disabled
    persistence-rebalance              : enabled
    header modify per-request          : disabled
    cookie-error-ignore                : disabled
    header-maxparse-length             : 4096

    urlcookie-delimiters               : /&#+
    urlcookie-start                    : ?
We have also tested the session directly with the Rserver .But it is not getting disconnected ( As we doubt is it any server related issue )
Also please find the below resource allocation .
resource-class TEST-FRONT
limit-resource all minimum 0.00 maximum unlimited
limit-resource buffer syslog minimum 0.50 maximum equal-to-min
limit-resource sticky minimum 2.00 maximum unlimited
So can any one please suggest me is there any configuration mistakes here .
If the configuration is ok please suggest me what more I have to do for making the stickiness around 60 min .
Regards ,
Sinjish.K

Sinjish-
Can you use the capture utiliy on ACE to gather a trace of the entire session - then filter out the traffic to just the client IP or the server IP and attach it to this thread? A showtech would also be useful to see if there are any anomolies.

Chris Higgins

UCCX 7.0(1) RmCm resource issue

I have an issue with our UCCX 7.0(1):
In RmCm -> Resource configuration
Just for one particular resource - the resource group changes from "Service Desk" to "Not selected" overnight and team changes from "Service Desk" to "Default". The next morning the agent is not able to login and we have to manually change both Resource group and team to "Service Desk" for the agent to be able to login. There are no issues once we manully reassign the resource to the correct resource group and team but overnight the resource group and team again changes to "Not selected" and "Default". I wonder what happens overnight that might cause this?
Note: I have attached a screenshot. And this only happens for 1 resource not anybody else.
Please help.

Hi Andrew,
Thanks for the reply. No, I don't know the exact time that this happens but it does happen everyday.I think you are wondering about the LDAP sync in CUCM and yes we do have an LDAP sync at 1:00 am everyday. This might have something to do with the issue but I don't know what. And no, nobody changes anything in the system - there are only 2 people (myself and another) with access to UCCX admin and we didn't do anything. And this happens only for this one user.

IEEE 1394 insufficient resources issue

We currently have a CVS-1454 with two cameras performing inspections. Due to circumstances with the inspection and machine, we are trying to move the inspections to the computer that is currently communicating with the CVS. We are getting the error "The selected IEEE 1394 camera could not be initialized because of insufficient resources on the IEEE-1394 bus". This error is only happening in Vision Builder. It is not happening in MAX.
The system specifics are: the PC is running XP SP3 with a PCI-8252 card. There are two Basler scA1390-17fm cameras performing the inspection. The cameras are using Format 7, Mode 0, 1392x1040. The PCI card is new out of the box, the cameras are a couple of years old. VBAI version 3.5, LabView 8.6, MAX is version 4.6.2.
I found the various articles on NI.com addressing this issue, but the recommendations have not had an effect.
Framerate & Packet size: In MAX the frame rate can only be set to 100Mbs. Reducing the packet size has no effect. It was set at the default to 1024, but we lowered it to 200 with no effect.
We installed the AVT Bus Driver Package, but when we switched to the AVT bus driver, the bus went away in MAX and then Windows went through the found new hardware wizard and we were unable to get the cameras to show up correctly in Windows Device Manager, nor did they ever show up in MAX. All the documentation I've seen looks like we should not need to install additional drivers for the Basler cameras.
The machine does not appear to have Hotfix 885222 installed, but I was contemplating trying to run this update anyway: http://support.microsoft.com/kb/955408
Alternate video modes: We tried to set the cameras to any other video mode. We can put one camera at some insanely small resolution, but then the other camera still doesn't work regardless of the video mode.
I hope I've put all the details out there. Any thoughts? Should we need to install anything else after switching to the AVT bus driver? I was hopeful that would solve the problem.
Thanks,
Paul
Solved!
Go to Solution.

I concur with Brad that your issue is surely the famous Microsoft issue whereby XP SP2 and SP3 downgraded potential throughput to S100, requiring either rollback to the SP1 1394 driver from Microsoft, or upgrade to Win7 where they finally fixed the problem.
Or using a substitute Microsoft compatible replacement 1394 driver, such as that offered by AVT.
But I'd respectfully differ with Brad that re. whether the AVT driver "worked right" or not... as it was only designed to work with AVT cameras - and will not work with Basler cameras. That was an intentional design feature. Or constraint, depending on one's perspective. ;-)

ClickOnce and a System.Windows.Interacticity.resources issue

Hi,
I'm publishing my wpf app with clickOnce. I have put all the stuff like dlls, reference, prerequisites and so on.
But, when I try to install it to a virgin virtual machine, it says me that I need the System.Windows.Interacticity.resources version 4.0.0.0.
I use the System.Windows.Interacticity.dll in my project, but I've never used the .resources. If I try to use the System.Windows.Interacticity.dll version 4.5 instead of 4.0... nothing changes!!
How can I include System.Windows.Interacticity.resources with clickOnce or exclude it?
I have System.Windows.Interacticity.resources in my bin/debug folders, but if I try to include it, it gives me a nullPointerException error.
I have tried a lot of other forums/discussions/tickets, but still nothing worked for me.
NOTES: updating my project with dlls and prerequisites, the System.Windows.Interacticity.resources began necessary. Before, it wasn't in this way.
Can I ignore it? or, how can I include it?
I saw it in the /bin folder, inside the folders with the language name (en, de, fr, it..). But if I try to refer to one of these System.Windows.Interacticity.resources,
it gives me nullPointerException.
This error is stopping my installer, so it is a big problem.
Thanks in advance,
Piero

Hello,
>>But, when I try to install it to a virgin virtual machine, it says me that I need the System.Windows.Interacticity.resources version 4.0.0.0.
1. To clarify this issue, you could share us the screenshot about that message.
>>I use the System.Windows.Interacticity.dll in my project, but I've never
used the .resources. If I try to use the System.Windows.Interacticity.dll version 4.5 instead of 4.0... nothing changes!!
>>How can I include System.Windows.Interacticity.resources with clickOnce or exclude it?
2. What did you mean by "use"? Calling method? Or did you added any reference to it?

"Motherboard Resources" Issue

Under Device Manager, System Devices, I noticed that I have "Motherboard Resources" listed three times. Am I missing something?
I've learned to leave well enoough alone with this thingie, and won't mess with them, unless someone here knows what they are and what I should do.
No living vicariously through my computer allowed!

I had that issue w/ Windows 2000 Advanced Server, but I recently upgrade to Windows Enterprise Server 2003, and it corrected the issue.
Prior to my upgrade, I tried about every bit of driver installation/unistallation, disabling/enabling I could think of to no avail. First time I have every run across a PC with this type of issue, though I do not think it impacts overall stability/performance, it's just an annoyance to us perfectionists

Motherboard resource issue

hey!
I have a K7N2G ILSR+2400xp.(just running onboard video untill I fix this issue) I just installed a fresh copy of WIN2000pro. In device manager, under motherboard resources there is an exclaimation mark!! When I open it ...it says "on PCI BUS" code 14 and says I have to reboot in order for this device to function...But when I reboot it stays the same. I have tried everything I can think of.(all updates,reinstall all drivers) when I try to update the driver it says it found one...and to reboot...again nothing changes..
The file that it seems to want to load is winnt/inf/machine.inf
Driving me NUTS!!!

yes as I mentioned...I've tried reinstalling the drivers..and all windows updates.

Cookie stickiness configuration issue with Cisco ACE

Hi,
We have configured a ACE (in standby mode) with ip netmask stickiness and wanted to configure cookie stickiness for a remedy server placed behind the ace. BMC has said that they use JSESSIONID field on the remedy application and i want to know the procedure for configuring ace to see this field and deploy cookie stickiness feature on the ace.
We tried configuring the ace to learn the cookie string dynamically and tried to insert the cookie in the server response to the client but both methods have failed and the user is not able to see the remedy app webpage in both occassions.
Are there any pre-requisites to be configured on the ace before configuring cookie stickiness feature? We would appreciate your timely response.
Thanks in advance.

Hi,
Refer the document below for sample configuration. If this still doesn't work a full config and sniffer capture required to verify this.

CCX agent/resource issue

Hi everyone,
We have a lab enviroment setup:
1x CUCM System version: 7.1.5.10000-12
2x CCX System version: 8.0.2.10000-41
we did everything by the book,
1) end user ( IPCCX line associated, Group permissions defined, device associated)
2) application user defined in UCM, devices associated to RmCm application user
If we check in CCX administration:
tools->user management->user view
users are visible and have agent capabilities
if we go to:
Subsystems->RmCm->Resources
we have no resources/agents available?
also see the attachments
Did anyone have similar experience?

Hi Aaron!
well, the restart of "Cisco DirSync" didn't quite do the trick.
i captured the "cisco desktop sync service" log, and found multiple errors,
Do these errors explain enything?
"ERROR LRMS2001 The LRM client failed to connect to any service."
"ERROR CACMI2000 LRM Error: Failed to initialize LRM Client."
"ERROR STD2001 Client failed to connect to any service."
"ERROR CADLRM2000 LRMClient could not get the list of LRM Server profiles from LDAP, connection may fail. Reason: "

CS6 HTML Resource issues

Having trouble accessign my HTML Resource files.
I'm doing exactly the same thing I did in our last magazine.
I triple checked my naming conventions
for all files. Im trying to link a button to a pdf file as a "Go to URL" command.
I've accurately typed HTMLResources/file.pdf in the URL line.
Still not working. Telling me "The requested URL was not found on this server"
This was easy before. Did something change that I don't know about?

must be on my end then.
I loaded it from the folio producer and the folio builder.
i guess ill try again.
ill try again.

Kernel upgrade to patch level 196, ECC 5.0, MSCS resource issue.

Hi,
We have 3 system landscape DEV, QAS & PRD on win 2003, oracle 10G, ECC 5.0.
Our PRD system is on MSCS with CI on node A and DB on node B.
Recently I successfully upgrade kernel off DEV & QAS system to patch level 196 of stack 18.
When I tried to upgrade the kernel of PRD system one of the cluster resource drive (The drive contains the usr folder) is automatically moving from Node A to Node B and I got the error u201Capplication server shut downu201D. We donu2019t have additional application server in the landscape.
Please suggest the solution.
