Auto Start five instances in one server

Guru´s
I have a server with five instances. When I restart the server randomly I have problems with some instances. (they do not rise).
In services (windows) I see all the services fine. But in EM I see that instance is down...
Is there a problem in windows when I have 5 instances ?? (in order to after a restart of the server some instances does not start)??

> Is there a problem in windows when I have 5 instances ??
Yes. Absolutely. It does not make any technical sense.
You now have to spend memory on 5 SGAs, and resources on 5 process monitors, 5 system monitors, database writers, log writers and so on.
Not to mention that you need 5 temp tablespaces, 5 sets of redo logs, undo spaces, etc.
Why? What does make 5 small SGA's better than a single large SGA? Or temp space? Or process monitor?
Do you think you scale that way? Oracle scales the exact opposite way. Instead of more physical databases (each needing an instance), Oracle's top end product called RAC scales by using a single physical database and adding more instances to that database - one instance per server.
Granted, there are exceptions where one may want to run multiple instances. Oracle 9i and 10g during a porting project. Forced to do so by using shrink wrap software that uses an "embedded" Oracle database.
But these are by far the exception of the rule. And unless you have a mother of server with virtualisation, what you are doing using Oracle, does not make any technical sense.

    Hi,
    You only have to consider 2 things :
    1. SAPTRANSHOST entry in hosts file will be the same for both systems
    this mean that both systems will share the same transport directory
    Regards,
    Wojtek
    This is not true.  Your SAPTRANSHOST will remain the same, but you can (and should) specify independent trans directories with the DIR_TRANS and and EPS profile parameters to designate where the instance trans files should be located (i.e. /usr/sap/trans_SID).  I recommend you make this change in the existing host first, and then clear out the trans directory.  Let the 2nd instance install into it and then alter that one too (thereby moving the files to the new /usr/sap/trans_SID2).

  • How to start two instances of InDesign server independently?

    Hello,
    we have a multi instance InDesign server installation.
    And we are able to start two instances of InDesign server on different ports.
    But now we would like to use different plugins for different instances.
    Is it possible somehow? For example install InDesign server two times in different folders or something like that?
    Thank you in advance.

    InDesign plugin loading can be controlled via a file "PluginConfig.txt", refer to search for details.
    InDesign Server has separate configuration folders per instance/configuration.
    *If* the search path for the PluginConfig.txt falls into this folder, that would be the easiest approach.
    I don't have a server installation with me to try it out.

  • Migrate Oracle Apps Instance from one server to another

    Hi All,
    We are planning on migrating our Production Oracle Apps Instance(11.5.10.2 and 9.2.0.8) on HP Tru64 UNIX OS on one server to a different server(Node name change) with the same OS. This is a single node, single OS user instance(Apps and DB on the same box). Can you please give me a brief idea on how to go about doing this?
    Thank you.
    Edited by: Ora_Apps_DBA on Jul 5, 2011 12:50 PM

    Since you will be using the same OS, then you can simply use Rapid Clone to migrate the Application/Database.

  • Multiple database instance on one server

    Hi experts
    We are planning to implement ERP, BI, Solman, CRM and MDSD on windows/oracle platform. There is an idea about system landscape that all database instance of production systems are installed on one server and central instances of each system are installed on separate servers. Is there any performance or maintenance risk about this scenario? What is the advanteges and disadvantages of this landscape? Shall we prefer central system installation?
    I'm waiting for your recommandation.
    Best Regards...

    Hi,
    From experience one disadvantage in having an Oracle farm, is if the server plays up
    or needs a reboot you of course lose all the systems databases.
    Also getting all customers to aggree a maintenance slot together can be a pain.
    Failover needs to be considered, DR also.
    IMHO separate servers, but that is my preference I'm sure there are advantages.

  • How to start new instance of Application server 6.0 sp3 on Solaris

    Hi!
    I am a new user of iPlanet Application server (ver. 6.0 sp3) for Solaris and I have problems with starting new instance of App. Server. Directory server and administration server are started during installation but application server isn't started. I've used Application Server Command Line Utilities to start server but I've got message "you must register
    the server instance via the application server admin tool". I've tried to do that but I don't know how. I've searched documentation and I haven't found what I'm looking for.I would like to know where can I find instructions for starting App. server?

    Hello,
    Start your "ksvradmin" from $IASHOME/bin/ksvradmin tool - a GUI tool and under file menu register the server instance by supplying port on which the server is running.. it is intuitive..

  • Several instances in one server from test purposes

    Hello,
    I would like to ask for your experience when dealing with installation of several software packages in one server.
    I'm not sure of my host specs (I deal more with software), just that it's an IBM something (I pray for multi processor but lets assume not) with lets assume at least 8 GB of RAM, and I would like to install SAP Netweaver 2004s (PI + EP mainly), CRM 2005 and SRM 5.0.
    Do you think this is possible, assuming the maximum number of people logged in at the same time in any of the applications would be 3?

    Hi Joao,
    You can install several different systems in the same box as long as you manage to configure memory and resourses to feed all those systems requirements. I have seen 4 J2EE engines in the same box and in another ocassion i saw 3 systems sharing a box with 4 Gigs of RAM, so I'm sure you can! Try to configure as less resouses as posible per system.
    Hope this help

  • Multiple processes for a host instance on one server

    Hi,
    One of the prod environment server memory utilization is getting very high every few days. I searched a bit and found that there are many processes for "BTSNTSvc64.exe" in the task manager. Whenever we restart the host instance a new process is
    getting created and the previous process is not getting killed.
    This caused multiple processes in task manager and every process is occupying some memory. The process is actually not active but it is creating some bad sectors which is causing the Memory utlization to become high.
    I am not able to kill the zombie processes either from Task manager. Server reboot is the option but wanted to know a permanent fix.
    Can you please tell me the reason as to why this is happening and also the solution? 

    How many BizTalk Hosts do you have defined on the system? If you have multiple Hosts defined then you're likely to see one host instance associated with each of the hosts. Each host instance is a service and in the "Task Manager" - Processes you will
    see multiple BTSNTSvc64.exe OR BTSNTSvc.exe * 32. This is OK is you have multiple host instances defined on your system (Services MMC will show you BizTalk Service BizTalk Group : BizTalk Host) and BizTalk Administration Console ->BizTalk Group ->Platform
    Settings -> Host Instances will also show you the different host instances. Each instance is a multi threaded process running different aspects of the BizTalk Framework/Components. So each process will occupy memory if it is "started". All this is normal
    behavior. If you're facing performance issues, you might want to ask the solution designer on their rationale for the number of hosts instances.
    So when you stop the service, it does not stop? goes into a non-responsive state? and creates another instance?
    Regards.

  • Multiple broker instances on one server

    We are running multiple OpenMQ 4.4u1 broker instances on a single server (two different environments, one development and one staging). It appears as though the RC file I installed in /etc/init.d on our RHEL server is designed to manage one and only one broker instance (using the $IMQ_ETCHOME/imqbrokerd.conf file).
    Is there an elegant way to have the single RC script manage multiple instances, or should I just create a second RC file and a second $IMQ_ETCHOME/imqbrokerd.conf file to manage the second instance?
    Thanks,
    Bill

    Yes, the MQ RC script is for 1 broker instance only. On Solaris, it's possible to use SMF to manage multiple processes/services. You may want to look for something similar on RHEL or clone/customize the RC script, imqbrokerd.conf and relevant links in rc?.d for each instance

    I think this might occur if you don't have the patch for SunAlert 46042 installed. There's more information on this critical Solaris security vulnerability, which was reported back in 2002, at http://sunsolve.central.sun.com/search/document.do?assetkey=1-26-46042-1
    Can you run the following command to check if you have patch 109326-09 installed and let us know the result?showrev -p | grep 109326If you don't have 109326-09 or higher installed, you should install it as soon as possible. You can follow the link from the SunAlert. Better yet, install the latest Solaris 8 recommended patch cluster from http://sunsolve.sun.com/pub-cgi/show.pl?target=patches/patch-access to make sure your system is fully patched and up to date.

  • VM auto start in a single server pool with only local hard disk repository

    I searched the forum but can't find anything similar.
    Basically, part of the dev environment I have is just starting to use Oracle VM to have a nice centralized place to manage the VMs and managed server.
    Those environment doesn't have shared storage and all VMs are stored under local hard disk. (as just having several VMs to share the resource in a single server)
    So there is only one server in the server pool.
    What should be the best way to set up VM auto-start when this single server is rebooting or start from boot up?
    Should I just set up a symlink of /OVS/running_pool/vm1/vm.cfg to /etc/xen/auto/vm1.cfg ?
    (p.s. I can't set up HA mode in the single server pool since this is ocfs2.local, it will fail)
    Thx in advance.

    After some testing, I'm now using a traditional way (for single server with local repository)
    auto start VM in dom0 during server starts up:
    ln -s /OVS/running_pool/vmname/vm.cfg /etc/xen/auto/vmname
    auto shutdown VM in dom0 during server shut down:
    - edit /etc/sysconfig/xendomains
    change the line:
    XENDOMAINS_SAVE=/var/lib/xen/save
    to
    XENDOMAINS_SAVE=
    I also change XENDOMAINS_RESTORE from true to false
    Now when I need to reboot/power down the server via OVM, I can just go ahead and do it without migrating..and xendomains will shutdown all my VMs and start them up next time.
