Cisco Application :: Application Slowness Through ACE 4710
Mar 27, 2013
Report run via Individual Web server URL’sThe report takes less than 20 minutes (average 15 minutes) to fetch and return the data. This is observed 9 out of 10 times.Report run via ACE Load Balanced URLThe report keeps on running for more than 20 minutes and never completes. The front end keeps showing report is running.The data in general when tested directly by running queries against the database (bypassing the platform) completes in 15-18 minutesThe network connectivity for each and every ports involved (Loadbalancer/Servers) have been throulgly checked.
i'm looking for a recommendation for a setup guide including ft i've had a quick look a wiki and i can get basics but i'm not sure about if i need to setup additional contexts etc when i'm the only one using the appliance?
I have an issue with a customer that wants to update a server behind the ACE. The problem is that when the application wants to update the server it does it with the name.Doing some research I found that you can rewrite the record DNS based on the static NAT you set up on the ACE. The feature is called DNS inspection. Is the same feature as the ASA (DNS doctoring).I apply it to the outside interface and it did not work.
With the current (A5) ACE 4710 lic setup, does the "X gigabit per second appliance throughput" that is licensed affect: -
A) Only "appliance" i.e. load balancing traffic, any other normal routed traffic is not included in the limit
B) Is it an overall throughput limit on the interfaces i.e. includes all traffic not only load balancing traffic but also normal routed traffic crossing the appliance
Looking at a scenario where the lic size I need for HTTP load balanacing would be one size if A) but would need to be much larger is B) to accomodate out of hours routed backup traffic crossing the ACE 4710
I've got a web app that the owners want to run over port 80, but also using SSL to secure private data in transit. The architecture is an ACE 4710 in SSL termination mode->Apache (port 2000)->Back-End app server.
I've got two VIPs set up already - one on port 443 and one on 2000 - both of which do the SSL termination quite nicely, but using the 3rd VIP set up on port 80, the connection steadfastly refuses to be HTTPS (i.e. doesn't show the padlock).
I've done all the set-up through the web interface so far, can this be done? If so, how?
I am currently running A3(2.6) and evaluate the possibility of upgrading to A4(2.1). The Instal & Upgrade Guide A4(2.0) mentions that A4(2.0) does not include all features of A4(1.1). Does this apply to A4(2.1)? The Release Notes mentions a list of features merged from A4(1.1) to A4(2.1) but does not clarify if there any features not merged.
we configued An ACE 4710 with SSL termination on Oracle Aplication Server 10g (10.1.2.0.2) ,so that SSL termination is done on the ACE and HTTP reaches the Oracle Aplication Server 10g (10.1.2.0.2) then we configure the ACE to enabled client authentication with Pkcs#11 smart card token certificate and this don succfully my problem need do this client certificate authentication for only the [URL] not for all SSL proxy service how can do that.
We have recently transitioned one of our Ecommerce products to a new data center, at which we now use a one-armed load balancing approach rather then the routed load balancing approach we used previously. This is casuing us some issues as we generally log the source IP address a user comes in on when he fills out an application. Now the logs only show the natted ip address recieved by the load balancer, which does us no good. Any way to log the source IP address when a new connection is created to a particular vip?
If we use an ACE4710 to load balance two real servers, obviously it will use health checks to determine if a server is down.When it detects a server is down, it will not send it any more traffic.But can we also have it take any other action? For example maybe email an admin, or send an SNMP trap? Or better yet, can we use a custom TCL script to do other things, like launch some custom activities?
I am new to the 4710 appliance.Apart from the 4 GE 'data' ports, there are 2 Ethernet 'management' ("console") ports. I find the description in the "quick start guide"somewhat confusing. URL, Is a first-time serial connection (at least to run the initial config. script) mandatory? Or can you obtain the same result via one of the 2 Ethernet management ports and using a default ip address (192.168.1.10 ? When running the initial config. script (only possible from the serially connected console i suppose), you have to select your management port. Why does the system in step 5 proposes you 4 ports, and not just 2? I suppose the intended port for management is one of the 2 management ports, not one of the 4 data ports?
I have a pair of ACE 4710s with 12 contexts sharing the load, running A4(2.1). esterday I upgraded one of them to A4(2.3) now I cannot telnet to the Admin context.Pings ok. I can telnet to other contexts on the box and everything seems to be working ok when i do a " sh telnet" comes back with
No Session Information is available sh telnet maxsessions telnet maxsessions 16
ACE# sh script code NORDICID_PROBE.Error: Called API is invalid or non-existant.Hardware is ACE-4710-K9 and software A3(2.7)The probe itself is functioning ok according to show probe detail.However show script script_name probe_name -counters all remain at zero for some reason. This wasn't the case on the previously use ACE software.To my recollection the command show script code has worked successfully before on the same ACE software. Not 100% sure though, but it definitely worked on the previous software we ran on the ACE.
We have two pairs of ACE 4710s, one pair running A3(2.4) and the other pair A3(2.0). We plan to upgarde the second pair so that they are running the same image as the first pair (we know they are not the latest, but this is the first step in a larger rollout plan, and to aid some troublshooting for a major issue we are seeing.)
I have details of the upgrade steps, but my question is with regards to the licenses which are now enforced after (2.0). We currently have the following on the first pair, but are these part of the default licenses for (2.4) or would we need to purchase these as well?
I need to use the Ace 4710 to distribute a Proxy PAC file, e.g. [URL] which will be configured in client browser using an AD group policy. Is it possible for the ACE to host and serve a file in this way?
Can the Nat Pool be on a different network that the load balanced vip? My current design uses nat pool on the same network, but the archatect wants the NATs on seperate VLAN.I will be developing on ACE MOD20, but the final configuration will be on 4710.
I configured ACE 4710 for HTTP traffic. All applications are running through real server. But when I run the same applications from virtual IP i.e through ACE. some applications are not running. Particularly applications having XML.
Is it ACE issue or Application issue. If it is ACE issue then how to troubleshot.
i have ACE 4710 appliance that terminate SSL and the connection to the servers is http.
The ACE (one Armed) is load balancing between two web servers and i am using stickness in order to take the connection on the same server based on cookie.I can access the website either by http or https., where on the web page there is a login credential to access using username and password.
When i access the website using https everything works fine and i can login to my account in https mode.When i access the website through http and login to my account the URL is redirected to https...normal because i am using action-list to rewrite the http into https. But when i exit the browser and access the website again using http it is not redirected to https(although i see that i am still login into my account i can see all the inforamtion in my account).
The customer wants the connection to be https even when i exit the browser and access the website again (within short time before the cookie exipres)
I have a Cisco ACE with a server farm "intranet" with real servers rsrv1 and rsrv2 (round robin) and i have two sites A (IP Address A) and B (IP Address B) in the WAN. I want to that Site A conect to ACE 4710 via VIP, but this connection will be to srv1 and Site B conect to ACE 4710 via VIP, but this connection will be to srv2.
Am trying to replicate the managment interface functionality of a CSS on ACE 4710 but have problem with it being treated as a general routed interface.
Scenario On ACE 4710 I have a front-end interface for client facing VIPS and a back-end interface facing a server farm, taking care of load balancing flows
Non load-balance system traffic for the back-end servers also flows through these two ACE interfaces, following a default route path (the back-ends use the ACE as default gateway) i.e. dns requests from the servers flow through the ACE egressing the front-end interface to hit a firewall and route to an internal dns server.
Issue If I add a "management interface" to the ACE 4710 and give it an IP address for management access, the interface by default assumes 'routed' mode and as the ACE treats this as a general interface it will route traffic out of it. For example if the IP address of this management interface is on the same network as the internal dns server, it breaks that connectivity. This as the ACE will see the "management" interface as best route to directly connected network and send traffic to dns server over that, however dns server response traffic will follow its defult route path via firewall and ACE front-end interface to get reply to back-end server. The firewall will block this traffic as traffic is asymmetrically routed and firewall not seen the initial dns request packet.
Question Is there a way of making an ACE interface a 'non routed' management only interface for out of band management use? That is ACE will not attempt to route general traffic through the interface
I realise I could achieve this with multiple contexts but want to have a single context for various reasons - i.e. to have a kind of like for like CSS replacement using ACE 4710
I configured cisco ace 4710 with ssl-proxy and it is not working,url..When i put https://10.1.41.20 the output is: "There is a problem with this website's security certificate", so i click in "Continue to this website (not recommended)" and the ace dont balance the output show error "Internet Explorer cannot display the webpage". [code]
I am running 4.2.1a and my topology is one subnet only so using one-arm thereby management svi, VIP, ft interface, and host server are all on same subnet.
With above scenario, is the ACE 4710 HA support on 3750 stack?
On 3750, I use port channel 10. Likwise channel 10 is config on both ACE and HA WILL NOT WORK
On 3750, I then use port channel 10 and 11. Thereby, channel 10 is on primary ACE and channel 11 on standby ACE and it works but with following observation:
- standby ACE is configured channel 11 and it syncs up but replace 11 with channel 10 then shutdown 10 and all interface has "channel-mode 11" removed. I have to put "channel-mode 10" on each interface instead of 11 and then unshut the "inter port-channel 10" - then add "ft-port vlan xxx" to get it to work
- standby ACE has "switch/admin" default hostname but I expect after sync that it would have the hostname I defined "ACE-COLO/Admin" instead
Looking for other discrepency as this is my lab environment before I implement into production as to decrease downtime.
i'm at the moment not able to delete a licence from a 4710 Balancer. The Problem: We've this ACE from our Service-Partner, and on the chassis was a SSL-7500 licence installed. The file was deleted from the partner, but NOT uninstalled!
Now, the ACE works with this licence: #show license status Licensed Feature Count
