Multiple application instance on the same server instance

Can we have multiple instances of the same application on a single WLS?? For ex, can I have two app.ear files in different application directories??

Hi Nilesh,
Can you please clarify your landscape as this will help in getting answers to your question.
In general adding instances (and/or server nodes) should be considered for increasing capacity rather than impoving performance. Specifcially, adding instances (and/or server nodes on the same host you risk a situation where the processes compete for resources which will have a negative effect on performance. If you do need to combine instances on the same host, make sure there is enough hardware (specifically memory in case of JAVA).
Hope this helps,
Best regards, Walter

Can you run multiple APEX listeners for different instances on the same server

Please confirm that we can run multiple APEX listeners for different instances on the same server? Is it an xml setup configuration or do we need to do more??

Is database link only 'valid' for instances in the same server?

Background: We have 5 servers and installed Oracle 7.3 and 8.
Problem: I managed to create database link to other instance in same server; but not to other server. Error message received was :
ORA-02019: connection description for remote database not found
: TNS server name not found
BUT: I managed it with 'copy from ' command in SQL*plus.
Question: Is database link only 'valid' for instances in the same server?
Thanks! ;o)

Hi,
We are planning to install second instance of Oracle 11gR2 in Linux server 2.6.39-400.21.1.el6uek.x86_64 x86_64. This is something we never haven done before. If you have such experience, please give us some insight.
The existing instance has all the standard ports:
Connecting to (ADDRESS=(PROTOCOL=tcp)(HOST=)(PORT=1521))
Enterprise Manager Console HTTP Port (pterpdb02) = 1158
Enterprise Manager Agent Port (pterpdb02) = 3938
What ports should we select for second listener and enterprise manager? Is there anything else that we need to know before we install the second instance?If you want a second database instance, no additional installation is required - as long as you want to run the second instance at the same version as the the first. Just fire up dbca and create the second database. One installation of Oracle (one ORACLE_HOME) is capable of supporting many database instances, though the same may or may not be said of the hardware it is running on.
As already said, one listener is enough. One listener, running from one oracle home, using the default name of LISTENER, running on the defualt port of 1521, is quite capable of -- indeed, WAS DESIGNED TO, supporte multiple database instances of multiple versions running from multiple ORACLE_HOMEs.
One instance of dbcontrol/dbconsole will support only one database. If you do not use Grid Control (extra installation, extra license) you will need to use the emca utility or one of the options in the dbca utility to configure a seperate instance of dbcontrol for each database. Don't worry about the ports, the creation utility will take care of it and report what it does.

Two instances on the same server

I've already created one instance on 11g R2 database, but I was told to create another instance on the same server. Can I use the same listener for both instance? Will it cause any problem?
Thanks!

Thanks for all your responses. I have not dealt with two instances on the same server before. I'll take your advice to start with the same listener for both instances and see if it is causing any issue. My database server is a Oracle Sparc 5120 with plenty of memory and disk space. The second instance that I'm going to create will be much smaller than the first one.
Single or multiple listeners aren't really a factor for performance. Notice that even in Dan's remarks, none of his reasons for multiple listeners had anything to do with performance.
Question, is it easy to create/configure the second listener to point to the second instance? Just in case there is an issue using the same instance.
The listener doesn't "point to" the database - not in the sense you seem to think. It simply watches the ports it is configured to use (1521 by default) for connection requests from clients. When it gets a request it evaluates whether or not it knows about the service (instance) requested, and if it does it spawns a separate server processes to communicate between the client and the db instance, then is out of the way. The listener creates the connection but does not sustain it. You can stop a listener and all existing connection will continue because the listener has no part in maintaining them.
Multiple listeners would be configured by adding LISTENER sections to the listener.ora file. You might find it instructive to realize that if there is no listener.ora, a 'lsnrctl start' will cause a default named listener to start on the default port of 1521. By default, any db instances on that server will register themselves with the default listener on the default port. After this self-registration, the listener will know about the instance if/when it receives any connection requests for it. Let's switch from the telephone analogy to that of a desk clerk at a hotel. He comes to work and is handed a piece of paper that says "We have Tom, Dick, and Harry registered as guests" This would be analogous to the listener learning of instances via the SID_LIST section of the listener.ora file. Then Fred walks up and says "I'm Fred and I'm in room 238", so the clerk makes a note of that. This would be analogous to the instance registering itself to the listener. Either way, then someone walks up and says "Where would I find Tom (or Fred)". The clerks checks his lists and directs the person to the correct room. He doesn't escort the person around to Tom and act as a go-between for their conversation. And hotel management doesn't want to have to pay a separate clerk for each guest.
You might want to read my articles about TNS in general at edstevensdba.wordpress.com. I think they will help you get a clearer understanding.

Multiple wiki's on the same server

Is it possible to have multiple wiki's on the same server. I do not mean having 2 wiki pages. however more like having 2 websites from the same server and each having their own wiki sites.
From just a quick play with the possibility both sites still reference from the same place so both sites would see the same wiki pages.
I was thinking of trying to use realms however the wiki info is not kept in the folder that is managed by realms

This can be done, but it really depends on the load balancer you use.
There is no recommendation from BusinessObjects and you might want to consult the load balancer vendor for instructions and support.

Dbconsole with multiple instances on the same server?

Hi!
I have a LINUX server running 2 separate instances - csp1 and csp2. I have a repository in csp1 and the dbconsole running for csp1. Now I need to find out if / how I can get the dbconsole running for the csp2 instance. This is Oracle standard edition 10.2.0.4. Both instances share the same Oracle Home and Listener. A second Oracle Home has the companion CD (http server) installed in it and has no instances associated with it.
Does anyone have information on how to do this? Here are some of my questions:
1) Do I need separate repositories for each instance or can the repository in csp1 be used for both instances?
2) Can the ports be shared or do I need to assign new port #'s for the 2nd instance? How / where do I do this?
Any hints, tips, suggestions, etc. are greatly appreciated!
Dave Venus

1) Do I need separate repositories for each instance or can the repository in csp1 be used for both instances?
Yes, in the free version of EM in 10g ie DB console,that's the restriction. You can't use it for more than one database. It has to be done explicitly for that another database whom you want to manage via it. So as per the answer, yes you do need a seperate repository for your second db. The other db will be in the same Oracle home and surely its em repository can work with the existing listener.But it does require its own set of config files which will be in a sperate folder under Oracle Home with its sid.
2) 2) Can the ports be shared or do I need to assign new port #'s for the 2nd instance? How / where do I do this?
As I mentioned in my last reply, you wouldn't be able to share the port that is already in use. You do need to have a seperate port configured. Normally when you would install the repository oracle would pick up itself a port number. The valid port range , if I remember correctly is from 5500 onwards ( I don't remember the last limit). Even afterwars, you can change the port using "emca" command.
Edit:
I forgot to mention that some time back, here on the forums, I had a discussion with a guy who mentioned that there is a workaround possible to add a target in the current Targets.xml for the second database. I did try it out but still that didn't give me two instances. The most recent one which I added only was accessible.
Update:
I did find that thread,here it is. See if this helps you,

CNR: Two cnr instances in the same server (lab environment)

Hello, we are trying to install two cnr 7.2 intances on the same server in order to replicate in lab the real environnment (failover local cluster) without deploying two servers.
I've seen on the installation guide that installing both a local and regional server on a single machine is supported, but what about two local servers working as a failover pair?
up to date, we've managed to install both installs, the dhcp servers are configured for using different interfaces and web gui are listening in different ports. scp ports have been changed (1234 and 4321 ) and, on dhcp-server expert configuration: failover-remote-port and failover-port are configured to be different (677 - 678 in one , and 678 - 677 in the other)
We can manage both servers from DHCP - failover configuration, as they show up and running, and even see logs... The other configs are
When trying to syncronize we get the error
"ChangeSet list is empty."
is this configuration supported?
best regards!

Multiple applications running on the same portal server

Environment : EP 7.0 SPS12
We have multiple portal applications running on the same portal with different login page for each application. On one of our employee portal, we want to put a login page link for another portal application running on the same portal which requires a different user ID and password to access that application.
The problem we are encountering is, the login page link we put in our employee portal is bypassing the login page for the other application and using the same session as the employee portal. What can I do to make sure application login page show up when accessing the link from employee portal?
Your help is really appreciated.
Thanks
Bhabesh Patel

Hi,
thanks for the clarification. I think I do understand now and the only thing I can think of is to delete the session cookie.
The problem with that is that you would not be able to use "simple" links (e.g. you could not just call the URL of the other application, but you would have to create some application (a simply JSP would probably be fine) that deletes the cookie and redirects you to the new application.
An other option would be to create DNS aliases that so that the session cookie is not sent (but depending on your setup this might have other drawbacks). Since the cookies are not valid for the other domains you would always start with a new login when you access a new application (e.g. the employee portal has the url portal.employee.company.com and the customer portal has portal.cutomer.company.com. Then (if the settings for ume.logon.security.relax_domain.level,see http://help.sap.com/saphelp_nw70/helpdata/en/5e/473d4124b08739e10000000a1550b0/frameset.htm is correct)
Hope this helps,

Running Multiple Web Dispatchers On The Same Server

Is it possible to run multiple instances of Web Dispatcher on the same server? I want to have one instance pointing to my WAS 6.40 system and the other instance pointing to my BW system. I have set up two services on the NT server: One named the standard sapwebdisp.exe and the other named sapwebdispbw.exe. I am using two separate profile files, one for each instance. The services start O.K. However, when I attempt to access my BW system using the HTTP port as defined in the BW profile and the Web Dispatcher profile, I get a message back saying that "The server you are attempting to access has refused the connection with the gateway. This usually results from trying to connect to a service that is inactive on the server." I have double checked that the service is running and that the BW system is up and available.
Any help is appreciated.
Regards,
Doug

Where can I adjust this !ALL and !J2EE group ?
Where can I manage the /link/ ? (like /irj/portal)
If you need any info please let me know.
THank you for your time & help

Running Multiple ODI Agents On The Same Server

Is it possible to run multiple ODI Scheduler Agents simultaneously on the same Server?
As we provide Work repository name in ODI params file and if we have different work repository
and we want to run schedular agent on same server how can we point to the other work repository.
Do we need to create another installation of ODI agent files on same server?
Thanks
Kashi

Hey Kashi,
You do not have to instal a separate Agent files again. All you need to do is to make sure that each set of agent has all the required parameter files which inclues, odiparams.bat , agentstart.bat and agentstop.bat(names may not be exactly same). Here is a website that gives you more details regarding creating multiple agents on same server

How to make Adobe acrobat feature to convert SAP Pages to PDF available for multiple users connected to the same server

We have installed Adobe Acrobat X Pro- English,Francais,Deutsch version 10.1.9 in our test environment and tried testing it for converting SAP pages into PDF with a few pilot users. In doing so we faced a challenge, where only one user at a time can use Adobe Acrobat PRO to convert SAP pages in to PDF.As long as the first user who is connected to Adobe Acrobat Pro via SAP isn’t logged off, other users connected to the same server are not being able to get the “Save As” dialog box to save the PDF in their preferred location.
This is a business requirement and we need an urgent solution for the same. Can anyone help us in telling us if this is possible and if yes the how to go about?

It's not something we deal with here, the LiveCycle products are a different world. Key points: Adobe LiveCycle is a range of products, some desktop, some server. LiveCycle PDF Generator is the one you should look at, it comes in 3 editions. License terms are by negotiation. Key management is via its Java API.

Multiple users connected to the same server

Hi there,
I was wondering if this scenario would be possible to be implemented on a Snow Leopard Server installed on Mac Mini 2.66:
- one iphone developer that needs to be remotely connected to the server to develop apps
- one project manager that will handle the project files and documentation. He will login to the server and upload/download files
- one app GUI designer that will login from time to time, to make the design in photoshop.
Can these 3 users be logged in the same time on the same server without any lag? Or this version of server will only support one user at a time?
Thank you!

Yes, you can do ssh and terminal connections, but I'm guessing that's not what you want here; I'm guessing you're headed over from X Windows or (more likely) Windows Terminal Services.
Google for Aqua Connect and related for the path that you're headed toward.
In general, Apple Mac OS X and Mac OS X Server runs one seat and one keyboard and one display per station, whether it's an Xserve server or a MacBook or whatever.

Clustering multiple instances on the same server

I've read reports of people clustering multiple instances of weblogic on the
          same machine to better utilize the CPU of that machine.
          So if I wanted to set up a cluster with four machines and two instances of
          weblogic running on each (port 7001 and port 8001) , what properties do I need
          to send into the startup command for the servers?
          How do you set this up
          Thanks in advanced.

          2) Create dirs: cluster1\myserver, cluster2\myserver
          3) create two startup scripts,
          specify -Dweblogic.cluster.enable=true -Dweblogic.cluster.name=cluster1 (or
          cluster2) in each script.
          4) Speicfy weblogic.cluster.multicastAddress=IPAddr in
          cluster1\weblogic.properties & cluster2\weblogic.properties, use different
          IPAddr for these two cluster.
          5) Specify weblogic.system.listenPort=7001 in
          cluster1\myserver\weblogic.properties & weblogic.system.listenPort=8001 in
          cluster2\myserver\weblogic.properties

How to install PI instance on the same server that has Solution Manager 4?

I am planning to install PI 7 on a windows 2003 server that has Solution manager 4 running on it already.
I am planning to install an additional Oracle instance and put PI on it.
What are the steps involved?
Please advise.
Thanks and regards,

Barry,
I went throught this link when I firt tried MCOD. may be the mistake I did was that I tired installing two separate instances like Sol Man and XI into the same oracle database. it used to fail at the step of Creating table Spaces.
I tired this when I saw some docs on MCOD (I think from IBM).
May be the approach was wrong.
Let me try this new method of installing two different Oracle instances and put Solution manager on one and XI on the other.
I will update you some time today.
Thanks for the help so far.
