Configuring multiple R/3 or BW instances behind TAM

We anticipate that we will have a problem when we attempt to access more than one back-end instance from the same enterprise portal when it is behind Tivoli Access Manager (TAM). Based on the way the TAM configuration, including the Junction Mapping Table (JMT), and the manner in which some back-end applications operate, we suspect there will be a problem reconciling a dynamically generated address to the correct back-end instance.
For example, we have multiple CRM instances in our landscape. We have implemented the IC Web Client through the Enterprise Portal, and have successfully configured it to work. When the back-end CRM system generates a url, it is reconciled properly because there is only one place where "/sap/..." exists in the JMT. However, because all back-end SAP instances have the same directory structures, any other CRM instance is going to generate the same url, but will expect the browser to return the request to issuing server. TAM intercepts all traffic and will only be able to route it to the first junction it finds, so multiple systems generating the same url will all be routed to one of the instances by TAM.
Has anyone encountered this? Is there anyone who has a solution? Ingo?
This issue will be a reality very soon for us, so anyone who has a potential solution please contact me.

Megha,
There are two options.
1. Create two WebSEAL instances as per the integration guide at "<a href="http://www-1.ibm.com/support/docview.wss?uid=swg24003605">IBM Tivoli Access Manager SAP ITS 6.1 / 6.2 Integration Adapter</a>", and configure the JMT for each TAM instance for the default ITS values (eg "/scripts/wgate" and "/sap/its"); or,
2. Change the default values of the second SAP instance in the instance's xml configuration file (ITSRegistryWGate.xml) to something other than "/scripts/wgate" and "/sap/its". Additionally, for SAP EP the default use of "/irj" can be configured to a different value.
Let me know if you require more in-depth information on either of these options. I can find the actual parameters, etc, for the files mentioned above...
Regards,
Pete.

Configuring multiple services in a single instance database

Dear All,
I would like to create multiple service names for a single instance oracle database (10.2.0.3 on IBM - AIX 6.1). I tried searching on the net, reading documentation, and also on the metalink but couldn't find anything relevant to single instance database.
Say I have two users, userA and userB, for which I would like to use two services (ServA and ServB) to connect to the same single instance database.
Any help in this direction is appreciated.
Regards

Thanks for your quick solution.
By the time you answered I was able to locate it in the documentation. I have tested it and its working perfectly. Here's the documenation link.

It is very hard to believe you didn't find this in the documentation, and my suspicion is you didn't search for it at all.It is very hard to believe that you don't trust others and end up in suspicion. I wish you were sitting next to me while I was searching for the link/document.It is because the vast majority of doc questions are asked by people who don't read the docs at all.
Now, I'm curious about your requirement. While it can be done, it is pretty unusual. That always leads me to want to step back from the technical question and ask What business problem is this solving?

Configuring Multiple OMSs Behind a Netscaler (SLB) Challanges

We are working through a active active OMS configuration (R4) with a Citrix Netscaler (SLB). We do not yet have the SLB setting correct.

As a rule, before configuring SLB, first execute 'emctl status oms -details' from $OMS_HOME/bin and get all the port details Eg. HTPS Upload port, HTTPS console port
Then configure the respective ports like 'Upload [ 4900 ] , Wallet [ 4889 ] and UI [ 7802] ' port in load balancer virtual servers and make sure the virtual server status is showing up.
Once that is done, run the secure OMS command
Eg. '$ /u01/app/oracle/product/middleware_r4/oms/bin/emctl secure oms -host mycompany.com -secure_port 4903 -slb_port 4903 -slb_console_port 7802 -console -lock_console
Once OMS secure is successful.. then secure the Agent using the HTTPS Upload port used in OMS secure command
Eg. $ /u01/app/oracle/product/agent_r4/agent_inst/bin/emctl secure agent -emdWalletSrcUrl https://mycompany.com:4903/em

How to configure multiple listeners to listen for the same instance.

Hello everyone,
I am running oracle database 11g and I want information regarding how to configure multiple listeners to listen for the same database instance. Actually I know how to configure more than one listener but the main thing that I am confused about is when we create listener.ora file, do we have to statically register the database instance with both the listeners or the instance will register itself with both the listeners.
According to my knowledge the instance will register with the listener specified by LOCAL_LISTENER parameter and we cannot have more than one value for this parameter.
Please only give detailed answers with example as I am tired of simple answers with details that I already know.

Hello,
Yes, it can make sense to have several listener for one Oracle instance. For instance you may have one listener for the applications another listener for DBA administration tasks as well as one listener dedicated to dataguard broker. It is not possible to have several listeners listening on the same IP and Port.
By default the database try to automatically register to a listener on port 1521. To instruct the instance to register to a specifc list of listeners you can add in the init.ora the local_listener parameter with an alias definition:
i.e
local_listener=MY_SET_OFF_LISTENERS
in your tnsname.ora add an entry called:
MY_SET_OFF_LISTENERS_LOCAL= (ADDRESS_LIST=
(ADRESS=(PROTOCOL=TCP)(HOST=myhostname)(PORT=1530))
(ADRESS=(PROTOCOL=TCP)(HOST=myhostname)(PORT=1531))
(ADRESS=(PROTOCOL=TCP)(HOST=myhostname)(PORT=1532))
In this sample your instance will register to three listeners listening on respectively port 1530, 1531 and 1532
If you want your clients can be balanced over the 3 listeners

Configuring multiple web sites in a single OC4J instance with 10g OEM

Hi There,
there doesn't seem to be a way of configuring multiple web sites within a single OC4J instance using the 10g Enterprise Manager Website, so can i assume that there's some performance related issues with doing this, or is it just a case of if you want multiple web sites, configure it manually?
We currently use 9iAS release 1 (which has been configured to use multiple web sites - with normally 1 j2ee app in each website - in a single OC4J clustered instance, using mod_proxy to forward the http requests onto oc4j), but we are looking to migrate to 10g very soon...
The initial configuration was done by an external company, so i'm not entirely sure of the reasons why it was chosen (perhaps so that if there was a problem with a single website, it wouldn't impact all our applications)..
Does anybody else currently use multiple *-web-site.xml's in a 9iAS release 2 or 10g in a production environment, and if so did you encounter any problems with the OEM website (assuming you configured them manually)?
Thanks in advance,
Andy

You can have several servers under one domain. No need to create a new
domain for each server. Just configure a server and make sure they are
listening on different ports. you are all set.

How to configure multiple listeners

I have installed 2 different Oracle instances on a single machine. I found that each oracle installation created its own Listener. I cant start both of the listeners at the same time. As a result, the respective applications cant talk to their corresponding database instances.
I could start only one listener for one database instance at any given point of time. Therefore, I am unable to use the other application.
Can any one please help me in configuring this appropriately so that both the applications can talk to their respective databases?

Tom,
looks like you are specifying http protocol in
sky.framework.ejb.SkySessionBean.getInitialContext method.
Change it to t3 or, if the JNDI lookup is in the same JVM, don't specify
PROVIDER_URL. If you have to use http tunneling due to any reason , you have to
enable HTTP Tunneling in server to which initial context is created. It is
disabled by default in 60. You can do so via console. Please refer to
documentation , let me know if you need additional help.

This advice applies to WL5.1. I have been trying to configure a

of the sample petStore available for test by multiple users.
I think in 6.0
You would need to open an admin server
Open the configuration file for say PetStore.
Clone the petStore- call it petStore2. .
Create a copy of the startup script and modify it to start PetStore2.
After doing this only one config.xml is created for both servers.
I am able to start the first server and view the petStore application,
On the second server I get an error when I do
http://host:secondServerPort/index.html
How does one create multiple instances in WL6.0 using the console

NT isn't a multiuser environment. I will assume that
you mean some
Win32 box sitting in a room where people can copy their
classes/EJBs and
test their stuff. If this is the case, the setup is easy.
Create a directory and startup script for every developer.
Have a
global properties file in the same directory as the scripts
so that
common settings are, well, common. Tell each user to
modify the various
parts of the properties files in their directories to
deploy EJBs and
register servlets, etc etc.
In each startup script, you will have to specify the server
directory
and the binding port for each person. Pick a port (something
easy to
remember and high, like 30000, 30001, etc etc) for each
person. Why?
Well, when they connect to the app server, they'll know
they're hitting
only their server. Also, TCP/IP won't let more than one
JVM bind to the
same port, so if you want simultaneous instances (> 4
you better have
one kick ass Win32 box) you have to do this.
Hope this solves your problem.

How to configure multiple IP-Adresses on one NIC in OVM

Hi guys,
we have some OVM Servers 2.2.1 installed. They all have three NICs in them (eth0-2). For eth0 and eth2 we need multiple IP-Adresses configured to work with our storage solution. The configuration should look like this:
eth0:0 - 192.168.31.x
eth0:1 - 192.168.33.x
eth1 - 192.168.0.x
eth2:0 - 192.168.32.x
eth2:1 - 192.168.34.x
I tried creating gonfig files ifcfg-eth0:0 in /etc/sysconfig/network-scripts with the following content
DEVICE=eth0:0
BOOTPROTO=static
ONBOOT=yes
NETMASK=255.255.255.0
IPADDR=192.168.31.3
TYPE=Ethernet
HWADDR=00:1b:21:06:f0:fa
But it does not work. Neither eth0:0 nore an additional xenbr is configured when i restart.
I can configure multiple ip addresses for xenbr0 by calling something like "ifconfig xenbr0 192.168.31.x". But these settings get lost as sonn as i reboot the server.
I have already searched google, forums and blogs for a solution but could not find one. I thought that this should be a pretty common task. In "normal" linux it is not an issue at all.
Has somebody any experience with a setup like this? I would really apreciate your help.
Thanks

Hi,
configuring IP aliasses seems to work the same way like configuring VLANs. You will have to configure the appropriate bridges at system startup manually.
E.g. this little script is what I use to configure VLANs and briges on my OVM:
#!/bin/bash
echo "Configuring VLANs and bridges\n"
echo "Configuring VLAN 24 on eth2"
vconfig add eth2 24
brctl addbr br2.24
brctl addif br2.24 eth2.24
ifconfig eth2.24 up
ifconfig br2.24 up
echo "Configuring VLAN 31 on eth2"
vconfig add eth2 31
brctl addbr br2.31
brctl addif br2.31 eth2.31

This script is run at startup by init using this startup skript in /etc/init.d, which is what I think you're missing as you can already seem to bring up the needed IPs manually - you'd have to change the chkconfig accordingly, that is make sure that the config script gets startet after the network has been brought up, like this: # chkconfig: 2345 11 91
[root@oraclevm01 ~]# cat /etc/init.d/vlan-config
#! /bin/bash
# vlan-config configure VLANs
# chkconfig: 2345 11 89

How to configure multiple IP addresses on one NIC?

Hi,
I just installed a OVM Server in version 3.2.1 and the according VMManager. Now i wanted to try to configure the Server/Server Pool. Now i come across a problem, which was already a big problem in OVM 2 while configuring the Networks.
All our OVM Servers have three NICs in them. One is for VMs and Management, the others are for connection to our SAN (Dell PowerVault MD 3220i). My problem is, that due to the network setup, the two NICs for storage need two IP addresses in two different networks each. This shouldn't be a problem, because usually in linux all you have to do is configure something like eth1:1. I remember having huge trouble configuring it in our OVM 2 cluster up to the point where I had to write a shell script to configure the second IP.
Anyways, I have configured two of the storage networks on eth1 and eth2 of the VM Server. Now i cannot configure any more IP addresses, because eth1 and eth2 are not available anymore for configuration in a third network. I really hoped that it would be possible in OVM 3 to configure multiple IP addresses. And probably it is only my lack of knowledge of how to configure it.
So any advice is well appreciated.
Thanks!

You should be able to do this by using "VLAN Groups".

Check out the VLAN groups section. You must great the VLAN groups before you can assign them to interfaces.

How to configure multiple clusters on the same machine.

I am attempting to configure multiple clusters on the same set of machines. I have set the cluster name and multicase IP addresses to be different for each cluster. However I am still getting and error that states:
"This indicates that there are multiple clusters on this network attempting to use overlapping network configurations."
Is this not possible? If it is possible, is there some further way i need to tell the VMs they are part of different clusters?
Thanks,
Jacob

FYI: I'm using the wrong multicast IP above. 224.0.0.1 is reserved and something else should be used. See:

How to Configure Multiple Purchase Requisitions per Service Order

Hi experts!
Sorry if this is in the wrong spot, but I was wondering how I can configure multiple Purchase Requisitions to be created from a service or maintenance order (IW31) based on the control key (or if it's even possible).
What would be the pros and cons of doing this? We currently only have one PR being created for one order (a 1-to-1 relationship), however now with implementing external services, we want 2 or more PRs created based on the control key. Is the control key the best way to go, or should I be looking at a different deciding field?
Thanks in advance!
Stephanie

Raj,
Thank you so much for the information. That does help! However business requirements are now changing to have different Purchase Requisitions created for a single order in the following scenarios:
             - New Purchase Req created for different operations (you explained how above, perfect!)
             - Seperate Purchase Req created for non-stock items (your answer above seems to group service operations and non-stock into the same Purchase Req).
             - New Purchase Req created if the order has already been released. (If the order's status is still at "Create", then the additional component can be appended to the existing Purchase Req. If the order's status is "Released", and a new component is added, a new Purchase Req is created).
As mentioned, you explained how to do the first requirement. Is there anyway SAP can handle the next two requirements using standard config and not customizing anything?
Thanks in advance!
Steph
