Application disconnection

Hi,

we have ADX-1000 and Oracle EBS two application nodes, most of the time users are complaining about the application disconnection and an error displays "network disconnection ......etc)"

Oracle EBS R12 is java application and SSL is enabled on this web application also. we have raised this issue with oracle support and they said its related to network not the application.

we have changed the network switches but the problem still persists. i have executed the following command on ADX,

SSH@adx#show interfaces ethernet 1

GigabitEthernet1 is up, line protocol is up

  Hardware is GigabitEthernet, address is 748e.f823.c200 (bia 748e.f823.c200)

  Configured speed auto, actual 1Gbit, configured duplex fdx, actual fdx

  Member of L2 VLAN ID 1, port is untagged, port state is FORWARDING

  STP configured to ON, priority is level0, flow control enabled

  mirror disabled, monitor disabled

  Not member of any active trunks

  Not member of any configured trunks

  No port name

  Transmitted 3297804 broadcasts, 26 multicasts, 4143342519 unicasts

  0 output errors, 0 collisions, DMA transmitted 0 packets

Note: For your ServerIron ADX 1016-4, only 0 10Gig ports are available for use.

Unavailable ports can be activated through license upgrade.

this displays the input errors, i am not sure about this, can i know further deep details/debug how to troubleshoot this problem

Is it related to ADX loadbalancer or not ?

Following details for ios version,

Re: Application disconnection

Hi,

is the error counter increasing with users getting disconnected?

Can you configure a fixed port speed on the ADX and the connected switches?

Maybe you can provide a configuration or parts of it.

To further troubleshoot this you can use the packet capture utility and run it for one client.

Re: Application disconnection

Hi Alex,

One more thing, i can ping the VIP at the time of disconnection but the Application response is network disconnection. i have configured the syslog for this, but i cann't see any log requests from end user for https traffic, while i can see http traffic in syslog .

server remote-name webap1 10.12.10.14
source-nat
port ssl
port http
port http url "HEAD /"
port 4443
!
server remote-name webap2 10.12.10.15
port default disable
disable
source-nat
port ssl disable
port http disable
port http url "HEAD /"
port 4443 disable
!


server virtual virtual-app 10.10.10.27
sticky-age 30
sticky-age-multiplier 30
port 4443 sticky
port 4443 session-id-switching
bind 4443 webap1 4443 webap2 4443
