Clustering w/ Multiple Instances per server

For performance reasons, we want to setup multiple instances of weblogic on each server in our cluster configuration.How is this handled in a cluster configuration? Is each instance considered another server in the cluster? Does each require its on IP address, or is a seperate port sufficient for each? Also, is there a way to configure the cluster w/o using multicast - there's issues with supporing multicast on our backend network.Thanks, Rick

Sure, if JVM uses native threads and the application itself is well-behaved
          concurrency-wise (very important!) it should be able to scale up on multiple CPUs.

Multiple instances per server

Back in January, I talked to Oracle about multiple instances on NT. They said I could do it but not recommended for production.
Finally received the 11.5.3 cd kit so getting ready to do the upgrade on development. In looking at the "upgrading" chapter of the "install" guide, the panel displays only show information for one instance!!! How do I enter information for other instances including a new demo database. Back in January, I was told I could share the appl_tops.

ISV embedding database with one instance per server limitation

Hi All,
As an ISV, it would be nice for Oracle to provide a better embedding solution than a silent install then having to script the creation of, or restore the database. Not because it's too complicated for an ISV to script, but purely for speed reasons. It's much faster to copy pre-loaded data files onto a machine than to create empty data files, load the data in, perform an analyze and any other scripts on the database. Dems just my thoughts.
However, my real issue is regarding the 'one instance per server' install limitation. As an ISV, if I choose to embed Oracle XE in my application - how can I 'guarantee' that my product can be installed on any given server. Picture this:
- We submit a proposal/ tender for a license to our software.
- Client, in conjunction with their IT dept adds internal costs, identifying servers that will run on, responsibilities, project plans (the whole works) etc.
- Client gets signoff from their management and pays for license.
- Client goes to install our software using Oracle XE just to find that another ISV has their software with Oracle XE embedded installed on the server.
- Client either has to find/ buy another server, or we lose the license. Either way, client is unhappy.
Am I missing something here? Is anyone else anticipating this problem?
Brad

Hi Florin,
Thanks for the response.. a good suggestion and our schema would be < 1GB so size would hopefully not be a problem. However, as soon as we plug into another appliation's Oracle XE implementation - we've potentially lost control of the database and it loses it's "embedded" nature. Probably not a huge problem if it's an application independant implementation of Oracle XE by an IT person, but if it's another ISVs embedded database - the dramas could start.
We effectively put our user's database within the control of another application who may not have considered the possibility of our data residing there. eg. They could do a 'drop-all' and we lose our database. Or tune the database right down and our application suffers. Or the user uninstalls that application and it decides to automatically remove Oracle XE (after all, that ISV thought it was an embedded application, right?). Do you see the potential issues?
Perhaps Oracle XE isn't as attractive for ISVs as first thought... I guess at the heart of the issue is the fact that Oracle XE isn't really an embedded database. It's just a database you can [silently] install with your application and then becomes a general db on the machine.

Applying Service Pack on multiple instance SQL Server 2008 R2 Cluster and Standalone.

Friends,
Its my first time I am applying Service pack to both Standalone and Clustered SQL 2008 R2 servers. I have multiple instances running on both stand alone and Clustered environment. I don't know how to apply pack with multiple instances. Do I need to apply
the service pack each instance one by one or I can just run the pack to each node of cluster and each box of stand alone server? Will I get any multi instance selection option during the installation process so that I can select multiple instances at once??

When installing service pack for multiple instances in a standalone machine, you just run the installer and it lists all the instances eligible for the update. You could do it one by one or do it at the same time. Doing it at the same time saves time and
energy. If you selected multiple instances then you dont have to do anything else.
In case of cluster, if you have multiple instances then you need to be little careful.
Eg: Assume you have a 2 node cluster Node 1 and Node 2. Two instances Instance 1 active on Node 1 and Instance 2 active on Node 2. What I would do in this case is to first failover any one instance to the passive node. Assume I failed over Instance 2 to
Node 1. Now Node 1 is active node for both instance 1 and instance 2 and Node 2 is passive for both instances. At this point I run the service pack on Node 2. Once patching is done, I reboot the node and then failover the instaces one by one to Node
2. At this point both instances 1 and 2 would get upgraded and will be active in Node2. Now Node 1 is passive and so run the update there. Once the service pack is installed, reboot and then fail back Instance 1 back to Node 1. Note: I would also failover
Instance 2 to Node 1 just to confirm that failover works completely after service pack update.

Multiple instance SQL Server not working between VM's

I'm working with SQL Server 2014 running on Windows Server 2012 R2 Azure VM and having problems connecting to the SQL Server instance from a Windows Server 2012 R2 VM running IIS. The connection string and setup is the same as I have been using for several
years. The main difference is I am now running multiple instances on the SQL Server. Firewall is configured properly, SQL is in mixed authentication mode, configuration is identical to all the servers as ones configured in the past. Would there be anything
in the Virtual Network or in Azure that needs configured?

Is this VM deployed in a Virtual Network? If so, make sure to use static IPs, so that, in case the VM is rebooted, the IP remains constant. If not, this may be the cause of your problem, the IP will change when the VM reboots.
If you've tried to connect to the VM from outside the Virtual Network, then you need to create an endpoint for the SQL port. This needs to be configured for each instance of SQL Server on the VM.

Max number of instances per Server

Good morning,
I've installed Oracle9i in a Windows 2000 Server with 1GB of memory. After that I've created several instances of Oracle DB. With 3 instances my server works acceptably, but after adding two mor instances I've begun to have some perfomance problems and the access speed has considerably decreased, so my question is, what is the maximum number of instances that the same Oracle server can support in order to optimize the access to the DB?
Thanks in advance.
Isabel

Hi,
I am confronted with a similar problem. ie, we have got several instances on the basis of one application/one instance. I am asked to regroup all these instances to one and only one instance containing several schemas to reduce the number of servers, number of instances and on the way reduce the administrative ( dba ) tasks. As i have got some knowledge of dba, I thought of installing this instance under Oracle 10g like this : an application on its own tablespace and the backup of this tbs via rman. So when an application crashes, I can make use of TSPITR to bring the database to its initial ( stable ) status. My questions are :
1° any re-initialisation of the database will sanction all the schemas. Is there any
way to avoid this ?
2° as different tablespaces be brought to a consistency status different in time via
TSPITR even if the controlfile happens to be the same ?
3° if I opt for UNDO management AUTO, there can be only one UNDO TBS
active at a time. As this won't render me to trouble when i need to recover
only one application ? or on performance ?
Any prompt reply will be greatly appreciated.
Best regards.

Reporting Point over remote multiple instance SQL Server

Hi,
The scenario is the following:
1 CAS SCCM 2012 R2
1 Primary SCCM 2012 R2
1 SQL Server 2012 SP2. 2 Instances. Each instance has Database Engine Services and Reporting Services - Native.
The CAS and Primary installation was OK.
The reporting point for CAS (default SQL instance) installation was OK.
The reporting point for Primary (named SQL instance) installation is not possible. The reports node at SCCM console is empty. Both of the SRS instances was automatically configured, at installation (Install and Configure).
The question is:
Is it possible to use the same SRS to host 2 reporting points? (1 for CAS, 1 for Primary. Each at different instance)
Thanks in advance!

Hi,
At another customer I get the same scenario. They want to use the same server for hosting DBs and reports for CAS site and 2 Primary sites.
The message is:
Site Component Manager detected that site system "\\ECBPPRQSM.MYDOMAIN.NET" is currently in use by ConfigMgr site CAS.
Possible cause: You accidentally configured this site system as part of this site and as part of site CAS.
Solution: Remove this site system from the list of site systems for this site or for site CAS.
The question remains basically the same:
Is it possible to use the same SRS to host 3 reporting points? (1 for CAS, 2 for Primary. Each at different instance)
Thanks in advance!

CPU_COUNT when more than 1 instance per server

Hi,
I wonder if there is any drawback when we got few instances on the same server from cpu_count point of view.
This parameter is derived by all instances like they are alone so all control structures are allocated independetly but there is more
resource needed when many instances in place.
Could this be potencial bottleneck ?
Regards.

The last time I checked the guideline the maximum CPU busy rate should be 90%
Here's more info:
http://www.dba-oracle.com/t_high_cpu.htm
The advice on that page is not very good - the most important point is the quote from IBM, which highlights the fact that there is a difference between single-user and multi-user systems:
<blockquote>
+"This holds true in the case of a single-user system with no need to share the CPU. Generally, if us + sy time is below 90 percent, a single-user system is not considered CPU constrained. However, if us + sy time on a multiuser system exceeds 80 percent, the processes may spend time waiting in the run queue. Response time and throughput might suffer"+
</blockquote>
In fact, it's a bit silly to give a single figure for the point where you should be concerned about CPU utilisation. The best reference for discussion is Cary Millsap's book "Optimizing Oracle Performance" which discusses the impact of concurrency on queueing. Instability in performance varies with the number of CPU combined with the percentage utilisation, and the break point sets in around the following levels:
<blockquote>
4 CPUs: 67%
8 CPUs: 75%
16 CPUs: 87%
</blockquote>
Your observation, thought that the OP should not mess with the cpu_count parameter is sound. Perhaps the only parameters that he should worry about are the parallal_max_servers and processes parameters to ensure that no one instance is allowed to run up more processes than the machine can handle.
(I find the best sources of information that bridge the gap between Oracle and the hardware are Kevin Closson's blog, James Morle's website - and a site from someone at Sun whose name I can't remember at the moment.)

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.

Do this for all your four machines
          1) Create dirs: cluster1, cluster2 under %WEBLOGIC_HOME%
          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
          6) If your machine is multi-homed, specify weblogic.system.bindAddr in
          cluster1(and/or cluster2)\myserver\weblogic.properties.

Server 2012 - Problem with multiple instances of RDS looking to the same license server. Server Pools requiring the wrong servers.

Hi All,
I have two domains, prod.local and test.local. On prod.local, I have a license server living on the connection broker. I have created a two way trust between the domains so that the RDS instance on test.local can use the license server on prod.local.
When I first setup the RDS instance on test.local and point it to use the license server on prod.local everything appears to work, all servers recognize the license server.
However when I log off and back on, and click the RDS dashboard in test.local, the Remote Desktop Services overview states I need to add every server from prod.local to the server pool. This is bothersome because the Remote Desktop Services on test.local
is still functioning, but I am no longer able to manage it. When I add the servers from prod.local to the server pool I am displayed the setup for prod.local instead of test.local
Is there a way around this? Can I use the same RDS license server key multiple times?
tldr: Using a different domain's license server causes my RDS instance in Server Manager to display the wrong RDS farm.

Hi Nathan,
Thank you for posting in Windows Server forum.
Please check the required ports must be opened on firewall.
- To issue RDS Per User CALs to users in other domains, there must be a two-way trust between the domains, and the license server must be a member of the Terminal Server License Servers group in those domains.
- To restrict the issuance of RDS CALs, you can add RDS Host Servers into Terminal Server Computers group on RDS Licensing servers.
- Configure RDS licensing server on all RDS Host Servers in each domain/forest. You can do it through RDS host configuration snap-in or through a group policy.
- Add administrators group of each domain/forest in the local administrators of RDS licensing server. This way, you’ll not get a prompt to enter your credentials when you’ll open RDS host configuration snap-ins in trusted domains/forests.

Multiple SPNs per instance?

Multiple Instance, Multiple Statically Assigned ports 'per' instance. eg;
Instance1 - ports 15000, 15001, 15002
Instance2 - ports 16000, 16001, 16002
Port 15000 - DatabaseA
Port 15002 - DatabaseB
Port 15002 - DatabaseC
Port 16000 - DatabaseD
Port 16001 - DatabaseE
Port 16002 - DatabaseF
Each 'instance' uses a different Domain User account.
Does each port need to be registered with a server principle name? Or is just one ok? Ie:
Instance1:
setspn -A MSSQLSvc/myhost.redmond.microsoft.com:15000 microsoft\domainaccountname1
setspn -A MSSQLSvc/myhost.redmond.microsoft.com:15001 microsoft\domainaccountname1
setspn -A MSSQLSvc/myhost.redmond.microsoft.com:15002 microsoft\domainaccountname1
Instance2:
setspn -A MSSQLSvc/myhost.redmond.microsoft.com:16000 microsoft\domainaccountname2
setspn -A MSSQLSvc/myhost.redmond.microsoft.com:16001 microsoft\domainaccountname2
setspn -A MSSQLSvc/myhost.redmond.microsoft.com:16002 microsoft\domainaccountname2

Hi,
I think you need to registry the SPN with the each different port numbers that was used by the SQL Server instance.
Per
http://msdn.microsoft.com/en-us/library/ms677949(v=vs.85).aspx
A given service instance can have multiple SPNs if there are multiple names that clients might use for authentication. For example, an SPN always includes the name of the host computer on which the service instance is running, so a service
instance might register an SPN for each name or alias of its host.
Note: an SPN must be unique in the forest in which it is registered. If it is not unique, authentication will fail.

Clustering Multiple Instances

Greetings All,
I am trying to perform a simple clustering of a web app on a
single server with a multi-server install.
Can someone please detail for me the process from A-Z on
accomplishing this? I'm guessing there is someone out there who has
figured out all the critical information that Adobe has omitted
from their documentation.
Please answer the following:
1) How do I configure IIS6 relative to multiple web sites
pointing to the same application directory.
2) What EXACTLY does the Web Configuration Tool do ... ??
(other than "join" the IIS to the CF application")
3) Can all the IIS web sites point to the same Port?
4) IMPORTANT: After I have clustered the instances, how do I
know from looking at the web page what instance I'm on? In other
words, how do know that the clustering is actually working?
Please, someone help! I have less hair this week than last
Regards,

Yes.

Multiple instances of ECM 11g on one server

I've read a few posts about installing multiple instances of ECM 11g on one server, but I have a few questions. My current set up is
A single Windows 2008 Server R2 server
8 gb RAM
Weblogic 10.3.5
1 install of ECM 11g in the base_domain
Database is Oracle 11.2
I want to add another instance of ECM to this server, but when I went to run the RCU, I was not allowed to use the same prefix for my tablespaces. Is this expected? I'm fine with using a different prefix, I just was surprised to see that I couldn't use the same prefix on this install since I was using a completely different database.
Assuming I use a different prefix... do I just add a new domain for this additional ECM instance? Is there anything else I need to know?
Thank you

I went to run the RCU, I was not allowed to use the same prefix for my tablespaces. Is this expected?Yes. It will create tables with the same name visible for a different database user (thus, the prefix).
do I just add a new domain for this additional ECM instance? Is there anything else I need to know?Actually, I think you can even install more instances to the same domain (this is more a question to Weblogic Server admins - I think there's been some posts recently on this topic). What definitely must be unique, is the port number. If you are OK with using different port numbers for your instances, it should be relatively easy. If you need the same port (e.g. 80 because of proxy limits), there are some ways how to redirect - it that case, two domains might be required.

Multiple instances on single server

Hi all,
I have a Solaris 10 server with 2x dual core CPU's.
I am wondering if it was at all possible to install Business Intelligence Server on this single OS twice? And if it is, can I split the CPU between the different instances?
The reason for this is that I would like both production and test/development installed onto the same OS to cut costs. But I don't want the test/development instance to use resources that would affect the performance of the production environment.
Ideally I'd like the 2 instances, with the production instance using 3 cores, and the test/development instance using 1 core. If the RAM could also be split that'd be great.
Thanks for your help in advance.
Cheers

Yes, you can have multiple instances of Presentation Services (PS) ([see my blog posting for details|http://rnm1978.wordpress.com/2009/08/25/multiple-rpds-on-one-server-part-1-the-bi-server/]) which would let you split envs, but you'd do that with a single instance of BI server. I don't know if it's possible to run multiple BI servers
I don't think you should be trying to do this anyway, several reasons why not:
1) It's not supported to run multiple PS on one server. That should be reason enough not to do this on prod.
2) If it's not possible to run multiple BI Servers on one server then you'd end up running one BI Server with dev/test/prod RPDs - you'd never be able to bounce your BI Server for dev work without taking down prod
3) Any time you needed downtime for dev, you'd affect prod
4) Any patching you wanted to do on dev might affect prod
5) Any experimental work you do that crashes dev would affect prod.
If you only have the one box available to you for costs reasons then you should be looking into virtualisation of some kind, eg http://www.virtualbox.org

Multiple Instances of OEDQ on a single server

Hi,
I am running a Linux Machine (Linux 2.6.18-308.1.1.0.1.el5), on which I have the latest version of Oracle 11g release 2 installed.
I have an instance of oracle Enterprise Data Quality tool running on an apache-tomcat-7 server. Port 8080
Now I have a requirement of Installing another instance of OEDQ on the same server, but a different APACHE_HOME directory and a different Port Number (8081).
So the question is, Can we install multiple instances of OEDQ on a single server?
If so, what are the prerequisites to be maintained.
I did my bit of tries, but ended up having issues with some java errors.
I have posted the error message below.

Can someone please tell me what is going wrong here?

Hi,
Multiple instances of EDQ on a single server is technically possible provided the installer takes care to avoid port conflicts. It is not the case that there is a single port used by an EDQ server, for example.
For various reasons, it is not officially supported; attempting to diagnose issues on custom installations on Tomcat is especially difficult and we do not provide documentation on this. In general, the requirement usually comes up for Dev/Test instances (as there is no performance advantage of using multiple instances on a single server), where we would recommend the use of virtualization where this is a requirement.
Regards,
Mike
