UCCX 8.5 - HA over WAN - Appadmin webpages run slow

We have constant and ongoing problem with the Supervisor and Administration webpages of our UCCX running extremely slow, we are talking 5 minutes + to change the skill of an agent.
Have had several tac cases open and problem continues to arise, so I am tending to believe this is a bug with HA over the WAN.  Wondering if anyone else with HA over WAN -- system Cisco Unified CCX Administration ---System version: 8.5.1.11004-25  has this problem?
I cant keep doing this:
Subject: SR 622308023 - UCCX Appadmin webpages run slow
Hi John,
Please try the following steps:-
à Login to the Secondary UCCX web-admin page
à Go to CCX Serviceability page from drop down box on the upper right hand side
à Then to Tools> Datastore Control Center > Replication Server
à Click on Disable CDS and HDS
à Wait for couple of minutes and then click on Enable CDS and HDS
à Then click on Reset Replication
à Then reboot the primary CCX Server through SSH session “utils system restart”
à Wait for 15-20mins and then reboot the secondary CCX Server through the same command and then wait for around approximately 20mins
Please try the above steps during off-hours and then monitor if issue re-appears after a day. It seems there might be some synch issue which might be causing this and the above steps can fix it.

Hi
I have this problem with one of my customers, or something similar - it's CSCug18648.
According to TAC, up to 30 seconds is 'acceptable/as designed'. We randomly (but frequently) get multiple minute delays, and it's due to some other process on the system locking some of the data. It should be fixed in ES03 for 8.5(1)SU4, which should be available approximately the end of May.

  • Basic Webpage runs slow on IE 7

    I'm trying to develop a prototype web page for my website. So
    far its nearly finished and runs fine on Firefox 2 and Opera 9, but
    falls to pieces on IE 6 and earlier and seems to make IE7 overload
    most pc's processors. Could someone give me some feedback on the
    code found at:
    http://www.csmayores.org.uk/csmark2
    I've embedded the CSS code within the page's header so you
    can easily see it.
    This website is aimed at the elderly so all measurements are
    done using relative units (em) to allow browsers such as Firefox to
    resize the screen content proportional without loss of integrity
    (So that the visually impaired can zoom in); could this be causing
    the problems?
    Thanks in advance
    Chopo

    It seems the source of the lagging on my system is the shadow
    on the background of the main text panel the
    “mainPanelBG” div tag. The shadow is a png
    (Images/CSM_Shadow.png) with an alpha (transparency) channel. It is
    only 10px by 10px large, but I doubt its the image size
    that’s the problem but rather the fact that IE7 probably
    doesn’t do a very good job of tiling a transparent png
    background over another background. If it has to go, I’ll get
    rid of it, but it seems a shame, especially as all the
    “proper” (ok I’m just kidding don’t slate
    me for microfobia) web browsers seem to cope fine with the webpage.
    To see the difference the lack of shadow makes try the
    following two versions of the website on IE7
    http://www.csmayores.org.uk/mark2_Shadow
    http://www.csmayores.org.uk/mark2_noShadow
    The problem is especially noticeable when scrolling up and
    down the webpage.
    I admit, some of the images need optimising, but I don't
    think this is contributing much to the problems I am experiencing
    as I have tested the page without the images. The one on the left
    margin is optimised as is the background (sort of, as I originally
    made it 2000 pixels long, this is just dumb and I am going to
    redesign the bottom and make it just 1000 pixels long. This should
    half the file size), the one that needs work on is the yoga session
    pic.
    Can anyone suggest any shadow workarounds for IE7 otherwise
    once I separate the CSS from the main webpage ill resort to using a
    different CSS document without the shadow for IE.
    One solution I am working on is tiling the shadow on the
    Right hand side only along the y-axis. This seems to be working but
    it makes it more difficult to offset the shadow downwards as well
    as to the right; however this is a miner compromise.

  • Uccx cluster over wan. cad login problem

    Hi. I have uccx 8.5 cluster over wan. When the uccx publisher is down, agents can't login- invalid password. Please help.
    Sent from Cisco Technical Support iPhone App

    Hi,
    Where are your agents situated in respect of the CCX and CUCM servers? Agents authenticate via CUCM or AD if AD authentication is enabled on CUCM have you confirmed that these are also reachable from the location in question? Have you verified serviceability on the secondary node to ensure the ccm engine and desktop services are running and in-service?

  • UCCX8 over Wan

    Hi there,
    Got some questions regards UCCX ver 8.x deployment.
    I have a customer with their Main site in one country and a remote site in another. They are connected with an MPLS link.
    Main site has CUCM6, UCCX7 and 14 UCCX agents.
    Remote site has 14 UCCX Agents connected via MPLS wan.
    UCCX8 HA and CUCM8 has now increased its Round trip delay to 80ms.
    So if we upgrade CUCM and UCCX can i do the following?
    Is it possible to deploy another UCCX server and Subscriber at the remote site and point the agents at the local UCCX server?
    Can this be done using HA or can i just add a second server to the UCCX cluster and use that for local access?
    Does HA mode mean that the UCCX Sub server wont be used unless the UCCX Pub falls over?
    Does it matter that i have less than 2meg on the MPLS Wan.
    Any help much appreciated..
    Thanks..
    T.

    Hi,
    I think the SRND for UCCX will answer all your questions.
    http://www.cisco.com/en/US/docs/voice_ip_comm/cust_contact/contact_center/crs/express_8_0/design/guide/uccx80srnd.pdf
    Roughly speaking:
    -- Yes you can have two UCCX nodes separated by WAN as long as the allowed round-trip time between the servers is 80 ms or less
    Instead of pinging from the server itself you better use the switch closesest to uccx (check the SRND)
    -- It is recommended by Cisco to have at least one cucm node across the WAN as well
    -- Agents can be located in any site
    --  For HA over the WAN heartbeats are send every second and failover is initiated if we miss 10 consecutive heartbeats (10 secs)
    -- I think you will have problems if you use a link less than 2 Mbps. Need to use higher
    You roughly need 1.2 Mbps for the communication between the UCCX servers over the WAN and 800 kbps for the communication between the UCCX and the CUCM over the WAN
    For additional information check chapter 4 of the above guide.
    Hope it helps,
    Christos

  • CCX 8.5 in HA over WAN on Island Mode

    Hi guys,
    Does anyone know what will happen with CCX 8.5 in HA over WAN configuration goes to island mode?
    So consider the following setup
    Site A Site B
    CUCM Node --- WAN --- CUCM Node
    CCX Primary CCX Standby
    Each site have their own local voice gateway and sets of agents.
    The SRND covers that if 10 consecutive heartbeat is lost then a failover will be triggered.
    However the SRND does not cover the scenario if the WAN is totally cut and Site A and Site B is completely isolated from each other.
    Does anyone know what will happen in this situation? Will both CCX Node become Primary and operate in its own right (just like Unity Connection cluster when they go to island mode)?
    Kind regards
    Daniel

    Daniel,
    Here is more of a "step by step" to your question:
    Page 68:
    http://www.cisco.com/en/US/docs/voice_ip_comm/cust_contact/contact_center/crs/express_8_5/design/uccx851srnd.pdf
    When the WAN link has a clean break:
    and by clean break I mean it goes down and stays down, it does not
    flap or provide intermittent connectivity
    1) The CAD agents will connect to UCCX server that they can communicate with
    2) The UCCX servers will connect to the CUCM Node that they can connect
    to for call processing
    3) The calls that get to the respective UCCX servers will go to the
    respective agents
    When the WAN Link is restored:
    1) The Nodes will decide which node is more "qualified" to become the
    master node, this is generally Node 1 aka the first node that was built
    in the cluster
    2) The CAD Agents connected to the node that becomes the secondary will
    fail over to Node 1 to begin accepting calls from it
    3) All of the calls that the new master Node were processing will not
    have any negative affect as they will continue to be processed by UCCX
    4) The calls that are in queue for the node that becomes the slave in
    the cluster will be dropped

    Hi Gergely,
    And thank you for your reply. i have found the issue. I have multiple triggers for the same script, and I had  the xferToSharedLine varialble set up when getting into the script from one trigger, but not when triggering the script via a different trigger, and therefore the variable was having no value, and getting Fast Busy.

  • Sharing an iTunes Library over WAN?

    Sorry if this question has been asked before but my searching of the forum here has only seemed to turn up questions and anwswers on sharing over a local network. Here is my question.
    Is it possible to share an iTunes library over the internet? And if so, how? If it isn't I'd like to know so I can stop trying to track down how to do this.
    I have a Titanium G4 at home running iTunes 6.01 using a cable modem and router. The router firewall has been setup with the proper ports for iTunes and FTP (FTP works fine). My work computer is a G5 running iTunes 6.01 connected via a DSL modem/router.
    I have no other issues connecting to my home computer from work, but I can't see my shared music at home on my work computer.
    Thanks for any info.

    Issue solved. Here is what I did. I setup my Mac at home so I could connect at work. Inside the iTunes library on my work Mac I created an alias to the iTunes Music folder on my home Mac. Since my library at home and work are exactly the same iTunes on my work Mac sees a local library file but is streaming the music over WAN from my Mac at home.
    The are some stops and starts as the connection is over WAN, but it's pretty smooth. Do not know what will happen if I need to add or subtract from the library on either Mac.
    Just bringing this to the front in case anyone is interested in trying it themselves.

  • Airport Extreme and External Hard Drive. Backup over WAN?

    Hi
    I'm new to Mac's and just got a macbook air and a airport extreme.  I connected my external hard (toshiba) drive to the AE and my computer will recognize it, but when I try to connect to it using Time Machine my external hard drive is not recognized as a device that I can backup to over my WAN.  I'm not sure if this is possible, but I would like to be able to backup over the WAN if it is possible.  Is it possible to backup using time machine over WAN using an AE and a non apple external hard drive?

    Time Machine cannot backup to a hard drive unless it is formatted in Mac OS Extended (Journaled), also known as HFS+.
    You have me scratching my head about backing up through the WAN port. Normally, the WAN port would be used for a connection from a modem.....or another router.
    However, if you have the AirPort Extreme configured to connect to another router via Ethernet, and the AirPort Extreme is set to operate in Bridge Mode, then you don't have a WAN port, they are all LAN ports, so it would not matter which of the ports that you used.

  • Time Capsule 2TB missing "Share Disks over WAN" option

    I bought a time capsule about a month ago. Setup was no problem. Have a MobileMe account. Successfully setup remote access using MobileMe. Needed to select "Share Disks Over WAN" under the file sharing tab which is under the disk tab in setup in order to make it work.
    Bought another time capsule yesterday and trying to setup in another location. This model does not have that "Share Disks Over WAN" option. Am I missing something? Did Apple make a change? I am not able to access this new drive remotely now, even with my MobileMe account active.

    "As I write this, I am using my wife's iPad to browse files and folders on the Time Capsule disk. I can switch over to the disk attached to the AirPort Extreme with a single tap."
    Awesome!  Hopefully I will have the same luck as you!
    "I said that Filebrowser will do a very nice job. One of my support policies is that I never offer advice or instructions unless I have done it myself.  "
    Well that's good to know going forward!
    "Make sense?"
    Yep - no confusion whatsoever.

  • The whole configure over WAN thing is confusing me I don't want anyone to be able to access my airport extreme over the WAN.  How can I check to make sure that is the way I have it setup?

    I just bought a new airport extreme and I want to make sure that is NOT set up for "configure over WAN".  How do I check to make sure that is how I have it set up?  I only want access to the base via WPA2 password

    Open AirPort Utility, select the AirPort Extreme, and click Manual Setup
    Click the Base Station tab located just below the row of icons
    Remove any check mark that might be in the box next to Allow Setup over WAN
    Click Update to save your settings and the AirPort Extreme will restart in 25-30 seconds
    For what it is worth, if you leave the box checked, any computer that tries to access the settings on the Airport Extreme will be asked for the device password....not the wireless network password.

  • Bonjour & disk sharing over WAN -Expert/Genius help required

    *Goal: Learn how to connect to my USB hard disk over WAN, share drive with specific people.*
    I'm trying to figure out how to remotely access my data on the external drive via connected via USB to my AEBN.
    I've spent several hours dinking around with my router, trying to see if I can access the drive over the WAN. I haven't found any manuals, discussions, or K-Base articles that spell it out for me. Below is a list of things I've done. Please indicate whether they are relevant, and if possible what the procedure is. Thanks:
    Conditions: I have a static IP address and through the DHCP tab I have assigned all attached machines a static LAN IP address.
    *1. Airport>Base Station: Allow configuration over Ethernet WAN port.* I've checked this box and can remotely admin my AEBN from my PC laptop (XP) via the Airport Utility.
    *2. Airport>Access Control: MAC Address Access Control.* I didn't know if this would help or hurt anything so I added the MAC address for all ethernet and wireless ports connected to my network and given unlimited or untimed access. +No noticeable difference.+
    *3. Internet>DHCP: DHCP Reservations.* As mentioned above in conditions, I've assigned an internal IP address for each device's ethernet and wireless ports, based on the MAC address. +Seems like this and Access Control are redundant except for the time settings.+
    *4. Disks>File Sharing:* Enable file sharing is checked, with accounts (configured), "Share disks over ethernet WAN port" is also checked, as is "Advertise disks globally using Bonjour". Not sure what to put in the bottom two fields (Workgroup and WINS Server) so they're blank.
    *5. Advanced>Port Mapping:* I've assigned ports to my iMac for gaming and SSH access but I don't think these would effect the USB disk would they?
    *6. Advanced>Bonjour:* "Use a wide-area hostname" is checked. My LAN network name is in the Hostname field, for Domain I just typed my WAN IP address, and I put something in for Name and Password.
    I'd love any assistance to figure this out.
    Lastly, how does Bonjour help over the WAN? Is there some sort of Bonjour application I open log-in, like FTP client software?

    Since this discussion has now been resurrected...
    The advice provided by chrisfenix will allow you to access the Airport drive from a PC on your private LAN.
    The preceding discussion, however, was on the topic of accessing the Airport drive remotely over the internet. To do that, you could still use the advice provided by chrisfenix but substitute the public IP address of the Base Station. To find that out (and answer a question posed earlier in this discussion as well) just go to http://whatismyip.com/ from any computer on your own network.
    To answer a question posed by the originator of this discussion - Bonjour is not at all necessary for remote access of the Airport drive. Those people who know how to use this feature will know what it is for and how to implement it - the rest of us can just pretend this feature doesn't exist.

  • Where to place files and folder in shared disk over WAN

    Hello, I have a new Airport Time Capsule 3TB and I want to share my disk over WAN for remote accessing.
    When I log to the server with my MacBook or iPhone, I see "Data" folder, and inside it I see my Time Machine backups.
    My question is: where, -in the Time Capsule disk-, do I have to place the files / folders that I want to share over WAN. I am afraid to damage or corrupt my Time Capsule backups.
    Thank you in advance.

    It is not possible to partition the Time Capsule drive.....unless you.....
    Pull the drive from the Time Capsule case....(voids the warranty)
    Install the drive in a separate enclosure or caddy
    Connect the enclosure directly to your Mac
    Use Disk Utility to partition the drive
    Reinstall the drive back in the Time Capsule
    This is a lot of work....and should best be left to a technician.
    All things considered, it would be better if you dedicated the Time Capsule for Time Machine backups only...and added another drive for your shared file needs, but few users seem willing to do this.

    The two machine are on different networks.
    My goal is to have Machine A send multicast data thru eth2 to be sent in the wan and to be received by Machine B on eth2 too.
    Obviously the two machine are on separated networks.
    I have tried everything I could but I cannot get machine B to pickup the messages sent by A. It worked fine when on the same LAN but not over WAN.
    The multicast address that I use it 239.55.55.80 and the port 4445.
    I think I have a problem to link the interface to my app ( I used setInterface and setNetworkinterface but nithing.) Also I cannot firgure out if the things that I am doing wrong are on the server or the client.
    Here is the code for the sever and client.

    Thanks for your help.
    This is really important for the project I am working on.
    Thanks again

    never Mind I found the issue
    The default value for TTL is 1.
    I was going thru multiple routers so I incremented the value and it worked
    thanks

  • Multi-master over WAN ?

    When will Multi-Master over WAN being supported ?
    Will it be in 5.2, and when will this release
    being distributed ?

    Yes...it'll be in 5.2 which is scheduled for the end of the calendar year (around December...).
    A beta version will probably be available sooner (may be just to selected customers though).
    Regards,

  • Does turning off DHCP remove option to Share Hardisk over WAN?

    I'm a recent Apple convert. I have a new Macbook and have downloaded all recent updates.
    I just integrated the Airport Extreme Base Station into my current home network. I have DHCP turned OFF in the AP because I am running a netgear router in my basement that is already connected to my Cable Modem. It needs to stay in the loop because I am using it to feed my XBox360, due to the issues related the Base station/360 interaction.
    Here is my question... Does having DHCP turned off in the AP, remove the checkbox option in the "Disks" section of Airport Utility toolbar to "Share disks over Ethernet WAN port"? Its MISSING completely. I've seen many instructions that reference that phrase, but the only checkbox I have on that screen is one for using Bonjour. I want to connect a usb drive so I can have a central storage so my wife and I can share itunes/photos/documents. So could it be that option disappeared due to turning off DHCP or is there some other issue?

    If you want to share your disks over WAN then you need to do the following:
    1. Assign a manual IP address for your AirPort. You can do this by running AirPort Utility and under Internet you need to change Configure IPv4 from Using DHCP to Manually.
    2. You need to port forward TCP port 548 on your main router to the IP address you assigned your AirPort. After doing this you will be able to access your AirPort disks by going to Finder, Connect to Server, and entering afp://<yourgatewayipaddress> You can find your gateway IP address by going to www.whatismyipaddress.com while on your home network.
