Basic configuration question on Server port configuration

Hi,
I'm a newbie in Cisco configuration. Using the Cisco 7604 load balancer, wanted to acheive two things firstly single ip for the applications and the failover of my servers.
Configuration description
I have an Application client connected to the vserver configuration (LAVSERV) on Cisco 7604 Load Balancer and two servers (JBoss) S1 and S2 configured to the real ip as configured in the serverFarm. All the three systems (Load Balancer,S1 and S2) are in the same LAN.
IOS configuration details
ip slb serverfarm LA
nat server
predictor leastconns
real 10.2.11.11
weight 255
inservice
real 10.2.11.211
weight 255
inservice
ip slb vserver LAVSERV
virtual 10.2.11.141 255.255.255.0 tcp 1813
serverfarm LA
no advertise
idle 65535
inservice
When I try connect to my servers through the client application I get connection exception. Basically I'm telling my client application to connect to webservice url http://10.2.11.141:1813. Due to the configuration on Load Balancer for servers, Load balancer should route my request to either of the Servers S1 or S2.
I have a doubt here, have not mentioned the port anywhere on which my JBoss (S1 or S2) is running.Is beacuse of this I'm getting connection exception, if yes, kindly let me know how to configure the port along with the real server IP.
Thanks in advance
Sanjeev.

Hi,
     I have moved my client to the system in other LAN, current client ip is 10.232.66.67.
and my current configs in 7604 are follows
Router#show ip slb serverfarm
server farm      predictor           nat   reals   bind id interface(s)
LA             LEASTCONNS          S     2       0
Router#show ip slb vserver
slb vserver      prot virtual                  state         conns    interface
(s)
LAVSERV        TCP   10.232.11.239/32:8080    OPERATIONAL   0
Router#show ip slb real
real                  farm name        weight state          conns
10.232.11.11          LA               255     OPERATIONAL    0
10.232.11.211         LA               255     OPERATIONAL    0
Now on both the real servers I see the request is coming but still the request doesn't reach my application (JBoss).
$ netstat -plan | grep :80
tcp        0      0 10.232.11.11:8080           10.232.66.67:6307           SYN_RECV    -
$ netstat -plan | grep :80
tcp        0      0 10.232.11.211:8080           10.232.66.67:6307          SYN_RECV    -
During the client application invocation I see the following changes in the detail ouput of 7604. From the wireshark logs (attached pic) I could see the request (SYN) goes to the servers but servers are not responding. My server application doesn't respond because it has not got the request. 7604 invokes 11.11 it doesn't respond to SYN request so it invokes 11.211.
LAVSERV, state = OPERATIONAL, v_index = 7, interface(s) =
virtual = 10.232.11.239/32:8080, TCP, service = NONE, advertise = TRUE
server farm = LAMP, delay = 10, idle = 65535
sticky:
sticky: group id = 0
synguard counter = 0, synguard period = 0
conns = 1, total conns = 30, syns = 94, syn drops = 0
standby group = None
Router#show ip slb serverfarm name LAMP de
LA, predictor = LEASTCONNS, nat =SERVER, interface(s) =
virtuals inservice: 1, reals = 2, bind id = 0
Real servers:
    10.232.11.11, weight = 255, OPERATIONAL, conns = 1
    10.232.11.211, weight = 255, OPERATIONAL, conns = 0
Total connections = 1
Router#show ip slb serverfarm name LAMP de
LA, predictor = LEASTCONNS, nat =SERVER, interface(s) =
virtuals inservice: 1, reals = 2, bind id = 0
Real servers:
    10.232.11.11, weight = 255, OPERATIONAL, conns = 0
    10.232.11.211, weight = 255, OPERATIONAL, conns = 1
Total connections = 1
If my client application talk to the real servers directly my server application gets invoked and client get the reply.
But same is not happening through the 7604.
Only change I do on my client config file is just uncomment the 7604 vip or the real ip for my client to connect:
#for real server
#webservice.url: http://10.232.11.11:8080
#for 7604
webservice.url: http://10.232.11.239:8080
I feel the packets which are reaching my real server through 7604 are not proper so my server application doesn't get invoked.

Weblogic Admin server port configuration

Hi All,
I want to configure the Admin server port from 7001 to 80. Since I cant access Admin console, can we change this using the config files.If so, which file I need to
modify.
Environment: Oracle Enterprise Linux
Pl. provide me some inputs.
THanks
Raj

Hi Raj
1. By default when you create a Weblogic Domain and choose all the defaults, it uses default port as 7001. There will NOT be any entry for this in config.xml file. Look for the file named config.xml file under yourDomain/config/ folder. You will not find any word like "7001" most of the times.
The entries related to this section are something like this in addition to extra tags between <server>...</server> for example:
<server>
<name>yourAdminServerName</name>
<listen-address/>
</server>
2. Take a back up of config.xml file. Make sure Server is not running. If someting goes wrong, use this backup config.xml file to restart the server.
3. Carefully edit config.xml file, the contents inside the above tag <server>...</server> by adding a new attribute as shown below by name <listen-port>
<server>
<name>DefaultServer</name>
<listen-port>80</listen-port>
<listen-address></listen-address>
<tunneling-enabled>true</tunneling-enabled>
</server>
All you do is add this one line: <listen-port>80</listen-port> within the <server>...</server> tags.
Restart the server. Access the weblogic console like this now http://localhost:80/console or http://localhost/console (port 80 is default and we do not need to type it manually).
Thanks
Ravi Jegga
NOTE: You can change the port from Admin Console also, siince you mentioned you do not have access to console, you can manually edit config.xml file.

FPN configured for message server port

Hello,
I would like to configure my Consumer Portal to connect to my Producer on port :8101 (the default message server port of the Producer). However, each time I try with this conifguration FPN breaks and nothing works - can't browse the PCD or see remote roles via Identity Management (when I switch the config back to point to port :50000 in the Producer object on the Consumer it works fine again). I'm not using a SAP web dispatcher between the two portals but Producer portal is indeed listening on port :8101 since I can hit it directly. Is this a limitation of FPN?
My http trace shows an ABORT message when trying to connect with the :8101 configuration.
The 8101 port is necessary to be configured in order to leverage our clustered load balanced environment which has the 8101 message server port listening and redirecting to a cluster of servers.
Patrick

When using Remote Delta Links one can configure the SAP Message Server's RMI-P4 port (3901 by default) for RMI-P4 communication.
For the HTTP load balancing you cannot configure it to point to the HTTP port of SAP Message Server (8101 by default) only the application server's HTTP port on the Central Instance (e.g. 50000) can be used.
But don't bother yourselves with this, because SAP recommends using SAP Webdispatcher for HTTP load balancing in FPN scenario, so don't use SAP Message Server directly for HTTP load balancing in the FPN connection setup!

Can I configure some ports on FI-6200UP GEM as server ports?

Hi,
I need your help!
I know FI-6100 doesn't support to be configured its some port on GEM as server ports.
Is it possible to configure some ports on FI-6200UP GEM as server ports?
And also, I wonder that some ports(1/9-16) on a port group(Second) can be configured as a server port(1/9-10), uplink ethernet port(1/11-12), FCoE port(1/13-14), and FC port(1/15-16).
Thanks in advance.
Paul

Hello Paul,
Yes, you can configure server ports on Expansion modules on FI 6200 series.
http://www.cisco.com/en/US/docs/unified_computing/ucs/sw/gui/config/guide/2.1/b_UCSM_GUI_Configuration_Guide_2_1_chapter_0110.html#concept_A552AD7757A549FB82D16A07D0EDA1E4
--------- snip ------------
All of the port types listed are configurable on both the fixed and expansion module, including server ports, which are not configurable on the 6100 series fabric interconnect expansion module, but are configurable on the 6200 series fabric interconnect expansion module.

Single Nexus 5548UP- FCoE configuration with multiple server ports

Hello Everyone,
I am new to Networking so please bear with me.
Here is some background information. We have a SINGLE Nexus 5548 UP switch to which we are connecting both the storage and the UCS C240 M3 servers (with CNA). Both the storage and server has 2 ports each going to this nexus switch.
We want to implement FCoE with this solution.
Below are the steps (for server ports) that I have followed to configure the nexus. But the port not logging into the SAN (no flogi) with the config.

Fixed the issue. "switchport trunk native vlan 6" was causing the issue. Maybe the storage and Servers were not configured with proper VLAN's. I removed the native vlan and everything logged in fine.
Any how I have configured a single zone with all 3 servers pWWN's. I know single initiator zoning is the way to go.
Can you please guide me if I can move these servers in their separate zones without any outages? If it helps, all severs have 2 pWWN's. The current zoneset is active with that single zone.
Please let me know if you need any additional details.
Cheers,
KS

Configuring additonal server ports

Hi, if i'm using 2 server ports per chassis, and wish to add another 2, besides plugging in the cables and settings the ports on the interconnect for "Configure as Server Port" is there anything else that is needed and is there any disruption to traffic ?

Hello David,
Re-acknowledging the chassis does not reboot the blades. The links between IOM and FI are flapped and are included to carry traffic between blades and FI.
---->>> What about changing from individual links to port-channel, will this require a re-acknowledgement as well ?
{Padma] Depends upon where we make the change.
If you change it under Equipment > Policies > , you need to manually re-acknowledge the chassis for the links to form a port-channel.
If the global policy is set to None for " Link Grouping Preference " and we are changing the policy for specific chassis ( Equipment > Chassis X > Connectivity Policy " to port-channel, then this configuration change automatically re-acknowledges the chassis. You will get a warning before saving the changes.
Fabric port channel is available when you have FI 62XX / IOM 220X / UCSM 2.0 hardware / software combination.
--->>> Using individual links what method does the FI use for sending traffic down 1 link as opposed to the other ?
[Padma] When using individual links between IOM and FI, traffic is distributed according to pre-defined configuration based on number of physical links
Supported physical links are 1,2 4 and 8.
Let me know how your hardware model and current number of links used between IOM and FI.

Outgoing server port configuring not in Mail 3.5 - problems sending mail?

I recently upgraded from Tiger to Leopard and one of the things I noticed is that in Mail 3.5 undere Mail>Preferences>Accounts under the Account Information tab, there is no longer the ability to select or change ports for the Outgoing Server.
In Mail 2.x, there was an Advanced button that would let you choose a different port and select SSL (or not). In Mail 3.5, this feature is missing. Does anyone know if the outgoing server port can be changed? The reason I ask is that when I travel, my ISP will not accept any of my outgoing mail because I'm not using my home IP address (especially with .mac). This is usually remedied by changing to a different, less common port for the outgoing server. If I'm unable to change outgoing server ports in Mail 3.5, is this going to cause problems sending mail when I'm on the road? Any help would be appreciated. Thanks.
Ed

If you pull down the bar in the outgoing mail server, you should be able to select "edit server list" and the window shows up where you can set up port.

No ''BS: SRM-Portal(Basic Configuration) V1'' in /NWA Deply and Change

                and click    > Deploy and Change
there is no "BS: SRM-Portal(Basic Configuration) V1u201D exist
i dont know Why, whether because my NW7.0 patch 14 need to upgrade? Or other reason

Hi,
You can also configure portal connection manually. Please check the Configuration Guide in SAP Solution Manager or offline downloaded configuration guide in http://service.sap.com/srm-inst SAP SRM Server 7.0 -> Configuration Guide for SAP SRM 7.0 -> Business Package for SAP SRM 7.0.
You can also access SRM via NWBC html in current SRM 7.0 SP06 without Portal. It is called Portal-Independent Navigation Frame.

Portal basic configuration

hi all
I'm a student, and an oracle portal beginner. I just got an internship in an IT company, where my first task is to create an portal. There is an application server already installed here, with BI, portal, wireless... I was told that the portal was installed (checked as an option during AS installation) but it is not confugured. Where should I begin and what basic configuration I need to do in order to start building the portal?

You can check by taking a look at the ports for each component.
The portal is actually served by several components. Webcache -> Apache -> oracle portal modules
Take a look at the portlist.ini file in the $ORACLE_HOME/install direcotry. Pay attention to the webcache port, webcache admin port, and apache (oracle http server).
Portal should be accessable by going to http://<servername>:<webcache port>/pls/portal with an out of the box configuration.
Also, to get you started, OPMN (oracle proces smanagement and notification) manages the processes for each component. You can type opmnctl from the command line with no parameters to get help on its usage.
Most management can also be done through the enterprise manager. It is usually on http://<servername>:1156/ you will have to login with the ias_admin account. You can get the port by typing emctl status iasconsole from the command line.
This is the same info I started with when i first started learning portal a year ago.

Basic Configuration and Support Pack Stacks

Hi everyone,
Just a general question about the Solution Manager 7 "basic configuration" stuff.
Are you required to perform the "Basic Configuration" everytime after you apply a new support pack stack to solution manager?
Or is it a one off, after the initial installation?
Cheers
Shaun

Hello,
https://websmp109.sap-ag.de/~sapidb/011000358700001927282008E has some information about your question.
Only some parts of SOLMAN_SETUP must be run everytime, other parts are optional. For an overview please visit the link.

Basic configuration AP-Switch problems

Hello,
I am having a problem when I try to configure my AP1131 to a port in a WS-C3560-24PS-S. I've always known that the switchort must be configured as a trunk.
I will try to give a clear explanation of what I've done:
In the AP.
1.- ip address
2.- default gateway
3.- vlans configuration
4.- map SSIDs to vlans
In the switch.
Only configure the port as a trunk
interface FastEthernet0/9
switchport trunk encapsulation dot1q
switchport mode trunk
This way I can do everything. Get access to the network, ping, telnet other devices, but not administer nor ping the AP. But if I configure the switchport as an access port:
interface FastEthernet0/9
switchport access vlan 10
switchport mode access
This way I can ping other devices from the AP, ping and telnet the AP from the wired network (my laptop). I can connect to the SSID but not ping nor telnet AP or other devices.
I hope that someone give a clue of what I'm doing wrong or forgetting to configure.
Thanks a lot

Have you tried going through the Wireless LAN Controller and Lightweight Access Point Basic Configuration Example (Document ID: 69719)?

Basic configuration in GRC 10 for portals

Hi Gurus,
Could you please tell me the basic configuration details in GRC 10 for portals.
Thanks,
Mukesh

Hi Mukesh,
You can refer to https://websmp230.sap-ag.de/sap(bD1lbiZjPTAwMQ==)/bc/bsp/sno/ui_entry/entry.htm?param=69765F6D6F64653D3030312669765F7361…
However there is no such guide on Portal integration with GRC, you might need to follow below steps:
1- Create one HTTP type RFC connection between GRC and Portal system.
2- Create System Alias in portal system for GRC system
3- Deploy the GRC Portal content in Portal system
5-Portal content comes with 5 work-sets and one security role.You can assign the portal role that comes with the Portal content to user in Portal and also GRC roles to the same user in GRC system.
Hope this helps.

Ameet

Willy introscope issue in Basic Configuration

Hi Experts,
I am facing issue with Willy introscope enterprise edition, we are unable to view the installation path in SOLUTION MANAGER 7.1 SP12, Basic configuration in step 3.
Can any body please through some light on this issue.
Thanks in advance,
Jana

Dear Janarthan, As a pre-requisite to this step you need to perform following first then take it head with basic configuration.
1. A diagnostics agent needs to be installed and connected to Solman on the Wily EM host.
2. The operating system user of the diagnostics agent needs to have read write access the Wily EM installation directory. (defaul : /usr/sap/ccms/wilyintroscope).
Also, You would need to have the Wily EM installed as suggested by Matt to resume the Basic Config at Solman.
