Two OEL on single machine

Hi,
I need to install two OEL on the same machine. Is it possible?
Install OEL 5.x and then Install another OEL 5.x. At the system startup I should get boot choices between two linux.
Any pointers?
Thanks,
Abhilash

This is possible but not all that pretty.
1) Install the first instance. Do _not_ accept the default partitioning;
2) Be sure to leave room for the second instance.
3) Put the boot loader into the MBR.
4) You only need one swap partition.
5) Now the tricky part -- read on.
6) Install the second instance but DO NOT accept the default partitioning;
7) Instead, choose the "use free space" for the second instance installation.
8) Reboot and choose.Why do you want two instances? If you just want to separate "work" from "home", then install one instance and create two additional partitions: one for each context you want to have. Then just mount the work-context partition over your empty "/home" directory, and vice versa.
But if your hardware can do it (check your BIOS) installing VirtualBox or VMware is much cleaner. With hardware virtualization support (HVM) you will not get much of a performance hit.

Two GUIs on single machine

Hi All,
Is there any way I can download and install two different SAP GUIs (version 710) with different patch levels on the same machine? My requirement is to use two different logon pads for two different patch levels in the same machine.
Thanks,
Yuvnish

I use Virtualbox(http://www.virtualbox.org/) for such requirements. Having a VM environment is useful for any testing as it should not effect your host as long as you have enough resources available(XP runs quite happily with just 512MB memory). Try it, it's free !

Thank you!

Hi,
Two system on single machine with same SID is not possible.
you have to use different SID to install two system on single machine.

Run two Database in single server

Hi...
I want to run two database into single server. For that I had created one another database.
But now I am not able to connect with two database at the same time.
When I am going to connect to another database i have to shutdown the first one.
Is it possible to connect and work on two database at the same time?
Thanks
pratik

You should have a good enough to have two or more instances running on the same machine.
The performance of a single instnace will always be better compared to having two or more instances on the same machine.
Is it possible to connect and work on two database at the same time?Yes

The second machine performance is much better compared to the first machine that has mutiple instances.

Two database in same machine

Hai
I want to create two database in same machine. I searched in google but no use.
Is it possible in oracle 9i r2?
If so,Anybody please help on that.

I want to create two database in same machine. You can have a 100 Oracle databases on the same machine. The issue though is why?
Why do you want to duplicate database overheads? Why two sets of system and process monitoring processes? Log writers? Database writers? Etc.
Why two SGAs? Why two system tablespaces? Two temp tablespaces, undo tablespaces? Two sets of redo logs? Etc.
You now have two database footprints. Instead of a single large SGA with properly sized buffer cache, shared pool, large pool and so on - you know have two smaller SGAs and smaller caches and pools that are now less capable and less scalable.
Why would you want to do this?
There are no sound technical reasons for running multiple database instances on a server - unless it is something like a 32 CPU/multicore server with 256 GBs of memory. But then why not use this as a cloud-type server on which you can run multiple server VMs? One VM for each database, as that provides more flexibility than multiple databases on a single server(physical or VM)?
In today's world of cluster and cloud computing, running 2 databases instances on the same server does not make much sense. And needs to be backed up by reason and logic that justify such an approach.

HLP:Serving forms in 2 distinct envirs from a single machine

We would like to set up the forms and report server on a SINGLE
machine in such a way that the OAS
can serve forms to 2 distinct groups of users: Developpers and
production users. Is this
possible ? If so, how do we do it ?
For example, say we have a form called 'A' that is used in
production. Now we have to modify and
test it in development. We only have 1 physical machine
available. Is there a way on only ONE
machine to serve Development form A to developpers and
production form A to production users ?
Of course we could have two versions of the forms and report and
use different names, but this
solution is not really easy to manage....
What about the libraries (PLL) and icons (and all other
attachable objects in FORMS)
Say I have 2 directories:
/disk1/dev/forms
containting FORMA.FMX
MYLIB.PLL (Used by FORMA) (Actually, my cartridge
and forms server is set up to use these directories)
/disk2/prod/forms
contaning FORMA.FMX (Production version)
MYLIB.PLL (Used by formA)
Do I have to set up 2 virtual directories ? 2 different forms
cartridges. 2 different forms server (on different ports)
For now, I only deploy in a single environment (DEV). The UNIX
environement from which I start the FORMS
server contains stuff like:
FORMS60_PATH=/disk1/dev/forms
+ setting specific to this environment (TK60_ICON, etc...)
How do I set it up to run forms in 2 distinct enviroments ?
What about reports variables (We are using the cartridge as well)
Thanks

Thanks wilfred,
yes I've read that manual. Probably not every single page ;-)
I agree that High-Availability is a very broad and complex topic, but my question is (although it was difficult to explain what i mean) only on a small part of it:
I understand that I can have mutiple instances on each level OC4J, HTTP, WEB-Cache, LBR But where or who excepts one single URL and leads the requests to the available AS
As mentioned in my post before, we may etst the Microsoft NLB-Cluster to divide the requests to the WEB-Cache Instances on the 2 AS and then the 2 Web-Cache proceed to the 2 HTTP and so on.
The Idea of that is that Windows offers a virtual IP-Adress from those 2 Windows-Server and somehow the requests will be transferred to a running WEB-Cache.
Does that work correctly with session-Binding ...
We'll see
thanks,
Mark

IBNS with two groups of XP Machines, one PEAP-MSCHAPv2 & one EAP-TLS

Hello,
I'm planning to implement a IBNS network. We have two groups of XP Machines. One group has machine certs and we're planning to check their certs using EAP-TLS. The second group of machines is managed by other departments, each having their own Active Directory, and configured with PEAP-MSCHAPv2. I'm not very familiar with this kind of setup, so hints are highly appreciated.
1. Can I assume that, when properly configured, we can differentiate the authorizations per group (for exemple, at least two VLANs one for group 1 and another one for group 2 - I must at least seggregate the users per group and can't mix them in the same environment, since they belong two different departments).
2. For the first group, no big issue. I can check against my central AD. For the users of the second group, since they can come from different departments, each having its own AD, can I differentiate them, by any means, to know which AD I'll have to query? Or do I have to query only one single AD? Is it required that all the users of group 2 belong to the same domain?
Thanks in advance for your help.

Two FQDN on one machine.

I am trying to consolidate services on to as few machines as possible. Since you can setup multiple IP addresses, is it possible to have two FQDNs on one machine? I want to use a server to host files on my private network but also provide a public website. I already have the entries in DNS. I just don’t know if I can have two FQDNs on the same machine. It is as simple as just adding the new address?

If you are just talking about web hosting for two fqdn, then add another site in ServerAdmin:Web
Apache suppport virtual hosts. You could have hundreds of FQDN running under a single IP address.
In your case, you don't even need two IPs, but you could use them- or at least use them transitionally until you modify DNS and then just use on public IP.
If you want to add a second IP to the machine, you duplicate the port in SystemPrefs:Network. Show Network Port Configurations, then duplicate the ethernet interface and give that interface it's new settings.

Can single machine have multiple JVM running ?

Hi ,
I have two questions.
1) I have running jboss4 and tomcat 5 running in single machine, does it mean that they are running in same same jvm?.
2) If no how i can configure the jboss and tomcat for running in same/different JVM but in same single physical machine?
Please help me
Thanks in advance

On the same Java installation - depends on how you run them.
2) If no how i can configure the jboss and tomcat for running in same/different JVM but in same single physical machine?For JBoss you set JAVA_HOME.
For tomcat - I dunno - should be in the documentation somewhere.Thanks for reply
for both jboss and tomact i have set jave_home to same the path, how i do ensure that they are running in same jvm instance.

How can multiple users use the same Creative Cloud Individual on one single-machine?

We have one shared graphics workstation, which is infrequently in use by different people - therefore we bought a single-workstation license (which we were referred to "Creative Cloud Individual"). In the FAQs it says it installs locally, but whenever a user different from the installing adminstrator logs in, he is forced to use the trial.
Is there a way to make the local installation usable on that single machine for multiple users?
Thanks in advance for your reply

Serenatasystems do the other users not have administrator access? What happens if they sign in using the Adobe ID tied to your Creative Cloud subscription? Do your Adobe Creative applications then exit trial mode?

Multiple servers on a single machine

Hi,
Can multiple server processes be run on a single machine?
I wish to compile each server module independently and run them individually so
that if one goes down,the other processes doesn't affect.
Can we start all the server modules using single tmboot command?
How can we write a bea configuration file that suits the above requirements?
Please suggest me on this.

Subhash,
It is normal to have more than one Tuxedo server process running on a
machine, exactly as you describe. In fact, if you include the system
supplied servers that run (BBL, etc.) then all Tuxedo applications have
more than 1 server.
I suggest that you take a look at the Bankapp tutorial that comes with
Tuxedo, this (and the associated documentation) should give you
step-by-step answers to all your questions.
Regards,
Peter.

How to handle sessions with two severs on one machine?

All,
I am having a problem with session cookies being overwritten when I host two apps on one machine running WebLogic 8.1 The apps are http://myserver:7300/app1 and http://myserver:7400/app2, and each runs in its own server.
Users will often access both apps at once, in two browser windows. If the windows are different threads in the same process, the sessions collide. For Internet Explorer, this isn't usually a problem since clicking on the shortcut multiple times launches different processes by default. Some browsers (Firefox, etc.) won't let you have two windows under different processes. Attempts to launch a second window 'detect' the existing process and appear to spawn a new thread. When this happens there appears to be no way for the users to use both apps at once.
I know this is happening because of the way session cookies are stored in the browser process' memory. The session cookies appear to me to be 'keyed' by the host name or ip address of the server. Does anyone know of a setting in WebLogic so that this 'key' includes the port or context root? Is this even something which can be controlled on the server side?
Thanks for any help,
Brian

Not quite sure what your intent is, but if you want to avoid a clash how
about giving each application a different default session cookie name.

Multiple instances operated on a single database on a single machine

Hi friends,
Can anybody tell that "Is it possible to operate multiple instances on a single database on a single machine"!?.
If so.., where this case is useful.
Please help on this doubt.
Thanks in advance.
Thanks
Srinivasa Rao

Hi,
I just asked whether it is possible or not. It is not much important. As you said, OPS will perform well if instances are on different machines. I agree on this. But I think we need to replicate the database on other machine also to run fast.Am I right?..If not, please correct me...
Thanks for valuable information.
I just re-read your post. When you say multiple instances on a single database, it sounds to me like you are asking about Oracle Parallel Server in 8i. I don't know why you would (or even if you could) have multiple instances on the same box. I don't think that would make sense since on of the benefits of OPS is to have more processing power by using multiple machines.

How to get active monitor-Multiple monitors connected to a single machine.

Hi,
How to get the id of active graphic device, in case of multiple graphic devices connected to a single machine(Multi-headed display/ multi headed nodes) using Swing.
Prashanth.

Ah, youre actually asking different things.
In your topic title, you say youre running separate instances
In your body text, you say you are under different user/schema
So tell me, do you have more than one database or not? How many entries in your TNS file?
I would say, for "multiple database instances"
SELECT
a.id, b.id
FROM
tableA a
INNER JOIN
tableB@OTHER_DATABASE_LINK_NAME b <--NOTE!
USING(id)And of course you will have to look up CREATE PUBLIC DATABASE LINK sql..

WebPart drop down values working fine on PostBack in Dev. Environment (Single Machine) not in Farm

We have three drop downs (ddlRotation, ddlOnCallType and ddlHospital) in our webpart. All values are being populated dynamically. One from list (ddlHospital) and other from tool part properties. For dropdown populated from list, we are storing values in
View State.
WebPart is working fine in development environment (single machine) while on production ( 1 front end, 1 index and 1 db server), drop down values disappear after post back. Below is the code.
protected void Page_Load(object sender, EventArgs e)
try
if (!Page.IsPostBack)
LoadData();
if (!string.IsNullOrEmpty(webPart._rotationDetail))
ddlRotation.Items.Add(new ListItem("All", "0"));
int i = 1;
string[] strRotationDetail = webPart._rotationDetail.Split(':');
foreach (string str in strRotationDetail)
ddlRotation.Items.Add(new ListItem(str, i.ToString()));
i++;
if (!string.IsNullOrEmpty(webPart._onCallTypes))
ddlOnCallType.Items.Add(new ListItem("All", "0"));
int j = 1;
string[] strOnCallTypes = webPart._onCallTypes.Split(':');
foreach (string str in strOnCallTypes)
ddlOnCallType.Items.Add(new ListItem(str, j.ToString()));
j++;
catch (Exception ex)
private void LoadData()
SPSecurity.RunWithElevatedPrivileges(delegate()
using (SPSite spSite = new SPSite("SITE_URL"))
using (SPWeb spWeb = spSite.OpenWeb())
SPList oList = spWeb.Lists[webPart.destListName];
SPListItemCollection setuplistItems = oList.Items;
if (setuplistItems != null && setuplistItems.Count > 0)
DataTable dtSetupData = setuplistItems.GetDataTable();
if (ViewState["SetupData"] != null)
ViewState.Remove("SetupData");
ViewState.Add("SetupData", dtSetupData);
else
ViewState.Add("SetupData", dtSetupData);
LoadHospitalCombo();
dateControl.SelectedDate = DateTime.Now;
else
// some error message
private void LoadHospitalCombo()
if (ViewState["SetupData"] != null)
DataTable dt = (DataTable)ViewState["SetupData"];
DataView dv = dt.DefaultView;
ddlHospital.Items.Clear();
ddlHospital.DataTextField = "TITLE";
ddlHospital.DataValueField = "TITLE";
ddlHospital.DataSource = dv.ToTable(true, "TITLE");
ddlHospital.DataBind();
ddlHospital.Items.Insert(0, "All");
Any help?

Running your code in try/catch and doing nothing on exception, is not a good idea. Please try to put logging in your code as I believe your code is throwing exception. It's difficult to say seeing such a code what's wrong. Maybe the list doesn't exist or
exists with different name/title, or viewstate is disabled or webpart properties are not populated... there's so many possibilities. Also if possible refactor your code as shown below:
//Your Code, you are loading all items from database and then counting it
SPListItemCollection setuplistItems = oList.Items;
if (setuplistItems != null && setuplistItems.Count > 0)
//Refactored Code
if (oList.ItemCount > 0)
