MSCS and multiple ASCS/JSCS instances

Hi
Outside of the HP Competent Cluster offering can anyone tell me if SAP are developing support for multiple SAP Central services instances in a single MSCS.
With the multiple Netweaver and SAP instances that are now required in modern landscapes,
coupled with the relatively high performance in SAPS of entry level servers, we need a cost
effective way of providing HA that maximises the potential of these servers and consolidates where possible.
It would also be useful to understand what the technical restriction is that prevents this at the moment.
Thanks
Mark

Hi Mark,
Sorry for the delayed reply on this.
I checked internally with our experts on this question. Here is an edited reply:
Our colleagues are working on a technical solution, which will make it possible to install multiple 640, 700 and 710 SCS/ASCS (kernel releases) instances on a single MSCS cluster:
We are planning to have a separate CD shipment which will support the multiple SAP systems and a separate document. On the CD will be included options:
- Clustreing First MSCS node
- clustering additional MSCS node
- Enque (ERS) instance installation
It can be for used for any 700 or 640 SCS/ASCS instance.
Support will be limited.
The following conditions for SAP support apply to:
->One clustered SAP system in one MSCS cluster with two MSCS nodes or one clustered SAP system in two MSCS clusters.
If you have one of these MSCS configurations and you use SAPinst to install such an MSCS system, you get SAP support with the installation, configuration, and operation.
->Multiple SAP systems with one or more MSCS cluster(s) and two or more MSCS nodes
For such complex MSCS systems you need in-depth knowledge of and experience with the Windows operating system, the Microsoft Cluster Service, the sizing and clustering of an SAP system. Therefore, the <b>installation and configuration</b> of such an MSCS system <b>must</b> be performed by an SAP Global Technology Partner, who supports any installation and configuration problems that arise from this MSCS configuration.
Only then does SAP support the operation of this MSCS system.

Matt

Multiple SQL Server Instances and MSDTC / AGs usage

Hello,
We are in the planning stages of migrating from SQL Server 2008R2 to 2012 to be running on Windows Server 2012, and I have a question about MSDTC, Availability Groups and multiple sql instances on a single box.
We have a couple of databases that rely on MSDTC so we know they can not participate in Availabilty Groups, but most of the other dbs we use DO NOT need MSDTC so I wondering the following:
1) Can I install two instanaces of SQL Server on a single box and have one using a local DTC, and therefore unable to use AGs, and the other instance on the same box NOT use DTC and therefor CAN use AGs?
2) If I can't do this, I assume each instance would need it's one machine. Is that correct?
Thanks
Eric

Hi Eric,
As described in this
article, for a given availability group, the availability replicas must be hosted by separate instances of SQL Server residing on different nodes of a WSFC cluster. Thus, we cannot configure a availability group for multiple SQL Server instances that reside
on a single node.
In addition, MSDTC is not supported by AlwaysON Availability Groups because
transaction atomicity/integrity cannot be guaranteed. For example, while
using a MS DTC transaction, after failover, the new principal contacts MS DTC. But MS DTC has no knowledge of the new principal server, and it terminates any transactions that are "preparing to commit," which are considered committed
in other databases. However, using Availability Groups together with DTC does not result in an unsupported SQL Server installation. For more information, please review this article:
Cross-Database Transactions Not Supported For Database Mirroring or AlwaysOn Availability Groups (SQL Server).

Single DB Engine and multiple DB Instances approach

Hi Tech Arch gurus,
Need some advice from all of you. We are currently planning to install SAP training systems to latest versions.
We are getting recommendations to goahead with Dedicated host for Oracle Installation where we have Single DB Engine and multiple DB Instances for all different 7 SAP Servers (ECC6, CRM7, BI/NW7.3, SOLMAN7.01, SRM7, EP/NW7.3, PI7.1).
Certain things that need to be clarified before we go ahead with this:
1.     How complex/simple is this approach ?
2.     If there are some issues noticed in the future (Performance issues etc) in this landscape , how much effort will be required to migrate out a DB instance for an SAP product to another machine. We would be having both ABAP and Java stack for our systems.
3.     We would later plan for adding some more systems into the landscape like SAP MDM, SAP CE, SAP BPC etc. If we add all these systems with a single DB engine, would there be performance issues etc. (We are operating under assumption that underlying hardware of the DB engine will be powerful enough)
Can you please provide some expert guidance on this approach?
Your response would be much appreciated.
Thanks,
MD

As a consultant I never dared to do different from what SAP says in guides or notes, at least when it comes to PRD systems.
For QA and Test Systems, discussions might be needed with the customer, depending on how important these systems are,
and for sandboxes I already did some stuff, that will even scare some Oracle guys
As Stefan says, the technical setup is not that complicate at all.
But I never had to fight for a support call in a non-supported Environment, so I can't say.
I always decided to be on the safe side.
If you have your Oracle License directly from Oracle you might disscuss such special support issues with these guys.
The problem is: If you get a call, and the first level support guy from SAP spots the non-supported environment, it MIGHT be possible that you need to escalate and may be pay for the support, but I suppose they will not let your system die
May be some of the SAP moderator guys can throw a comment in on this.

Diff between Multiple Threading and Multiple instance.

Hi ,
what is the main diff between Multiple Threading and Multiple instance?
Please give me the answer

Really. Seriously. Now if you had some industry standard phrases you were comparing, there might be a useful discussion. But those are just words strung together. If that's a homework question, I recommend you find a different teacher.

Is it possible to deploy SharePoint or its Service Applications on: multiple DB-Servers and multiple SQL Instances?

Hello Forum,
We have a SharePoint 2013 farm (Enterprise edition) that uses one single SQL Server 2012 (Standard edition). That statement means: All my SharePoint DBs e.g. (Config, Admin, Content, and Service Apps) DBs are hosted and running onto one single instance e.g.
Server1\SQLInstance1.
We have some new requirements to install and configure BI tools such as: PerformancePoint services and PowerPivot. BI tools require either SQL Server 2012 Enterprise or BI editions, and we do NOT want to upgrade our current SQL Server1\SQLInstance1
Instead, We have other separate SQL Server instance which is enterprise edition let's name it (ServerX\InstanceX) that is running standalone, and we are thinking or using it, and my 2 questions are:
1) Can we use this other separate
SQL Server instance which is enterprise edition to host the create and hosts the DBs of PerformancePoint services and PowerPivot ?
2) My second question is the same: Can I create PerformancePoint services application in my SharePoint farm, But in the Database Server field, I fill up
the details of the other DB server ServerX\InstanceX which is the one that is SQL
enterprise edition ? Will this work ?
Any official Microsoft resources/links tell that it is possible to deploy SharePoint or its service applications on multiple DB-Servers and multiple SQL Instances?

Thank you Alex and Anil,
What are the ramifications of that?
I mean, Assuming that I have created such a farm where most of SarePoint DBs in Standard SQL instance while the PerformancePoint service application and others e.g. PowerPivot and reporting service are deployed and configured onto other Enterprise SQL instance.
Are there any recommendations or concerns that you would like to draw my attention to ?

Multiple AD FS Instances/independent AD FS Servers in one domain or forest

Hello together,
Is it possible to install multiple AD FS Instances on independent AD FS Server in one Domain or Forest? If yes, is that supported from Microsoft or best practice?

Hi Ulrich,
Is it possible to install multiple AD FS Instances on independent AD FS Server in one Domain or Forest?
Yes, it is possible. Actually, multiple instances in a single ADFS farm are very useful for fail-over.

Multiple AD FS instances in single forest

Hi, thank you for reading this. I have a little design question about AD FS. The current situation is like this:
One forest, root domain: domain.lan
domain.lan contains all user objects
Three child domains: 1.domain.lan, 2.domain.lan and 3.domain.lan
AD FS 2.0 server is deployed in domain.lan
Customer wants an extra AD FS instance for testing purposes.
I do find some recommendations on the internet, but I still have a few questions:
Is it true that only one AD FS server (or farm) per forest can be deployed?
I read that I can have multiple AD FS instances, but not in the same domain. Should I move the current AD FS server to 1.domain.lan (Because the current AD FS server also automatically supports the child domains) and add an AD FS server for testing
purposes to 2.domain.lan?
Is the configuration as suggested in point 2 supported by Microsoft?
Thanks!
Regards,
Baksteen

Hi Mike,
thank you for your response. I also find the link you provided and it is says that it should be possible, but that only one instance can be active.
In this thread the same user (Mylo) says it is possible:

In this thread they talk about one instance per forest:
http://serverfault.com/questions/554199/are-multiple-adfs-instances-needed-when-federating-to-the-same-party-multiple-ti
In this link they say it should be possible with some downsides:

In this link they say it is not possible:
http://community.office365.com/en-us/f/613/t/82093.aspx

Best Practices for Multiple Forms-Reports Instances (WebLogic) on Win2008R2

Hello all,
I’ve succeeded in creating two instances of Forms/Report (FR) in WebLogic and am looking at about 5 or 6 FR instances on a one Windows Server 2008R2 box. I understand each instances will have its own folder (FR_Inst1) structure under the Middleware folder. Currently I have two instances configured each with its own Home (FR_Home1 & FR_Home2) and Domain (FR_Domain1 & FR_Domain2). Both the of the separate FP applications function correctly.
Can multiple similar type instances share a single Home (FR_Home)? Can multiple similar type instances share a single Domain outside of the WebLogic Domain, such as FR_Domain?
Thanks,
Ron

Thanx for the reply! I read through the documents and they are very good at explaining how to install the different components individually. I still can't find much on installing them together. I hope it's not just going to be a trial and error thing.
So far I've installed done the following successfully:
Installed 10.3.5 weblogic
Forms and Reports 11g on top of 10.3.5
I've created an additional managed server for our ADF applications.
My next step is upgrading the JSF to 2.x. I would have to stage patches 12917525 and 12979653. I'm afraid it will break the forms and reports though. Any ideas?

Multiple portal server instances

Hello,
I have one solaris box with JES 2005Q4 installed. I need to set up portal application development environment for multiple developers. I'm thinking about having multiple portal server instances. Is this configuration possible? Should I create multiple directory server and access manager instances as well or is it possible use one with multiple configuration instances?

Installing multiple instances of portal is only possible if you are installing in a Solaris 10 Whole-Root Zone. Create a new zone for each developer and then install all of the necessary JES components in each zone. This includes Directory, Access Manager, Application Server, and Portal.

How to deploy across multiple mid-tier instances

I was hoping someone may be able to point me in the right direction. We have two portal/webcache mid-tier instances on release 10G AS 9.0.4.2. On the ias_admin home page I tried to create a cluster and add the two instances to a cluster but it won't let me do it for a portal type install. If that is the case, how do people handle deploying such things as portlet providers and data sources across multiple mid-tier instances? Here is the concern from our Portal admin:
As discussed, the inability to cluster the mid-tiers will cause issues in production as we try and keep deployed portlet providers with their required configurations and datasources in synch. While deploying and configuring 1-2 mid-tiers for a given portlet manually is do-able, the chance for out of synch components or configuration settings is amplified for each additional mid-tier. If we manually deploy 5 mid-tiers and accidently mistype the datasource for example, we'll have a random error that will occur once requests are attempted to be serviced by that mid-tier. This will make troubleshooting difficult. We really need some way to deploy and configure settings one time and have these items propagated to all the other mid-tiers.
What is the best way to handle this scenario?
Regards and thanks for any info,

Parsing XML and Storing values in instance variable

hi,
i'm new to XML.
here i'm trying to parse an XML and store their element data to the instance variable.
in my main method i'm tried to print the instance variable. but it shows "" (ie it print nothing ).
i know the reason, its becas of the the endElement() event generated and it invokes the characters() and assigns "" to the instance variable.
my main perspective is to store the element data in instance variable.
thanks in advance.

I believe that the problem has to do with the value you assign to ctelement. You are assigning the value of localName to ctElement, however for the element: <name>...</name> the localname is empty string i.e. "", but qName equals "name". Because you are assigning empty string to ctElement, when you do the comparison in characters of ctElement to "name" it will always be false. So in startElement change it to ctElement = qName; Try it and see if it works. I have produced similar programs and it works for me.
Hope this helps.

New 13" Macbook Pro trying to connect to a Panasonic VIERA TC-L42U30 as second monitor. I've used multiple hdmi-thunderbolt/mini displayport adapters and multiple hdmi cables and still no success. The Macbook does not sense the second monitor (TV). Help?!

I've been a Mac since 2008, so I know my way around the system pretty well. This issue, however, has me stumped. I had an iMac until now and only now am I experiencing some difficulty with my new MacBook Pro. The model I have is the newest 13" Macbook Pro model and I'm trying to connect a Panasonic VIERA TC-L42U30 42" HDTV as a second monitor via the Thunderbolt port.
It worked the first two times and hasn't worked since, after 10-15 attempts with different configurations, turning things on n off, restarting the mac, unplugging the cables, adapters, TV, resetting the P RAM, etc... I've used multiple hdmi-thunderbolt/mini displayport adapters and multiple hdmi cables and still no success. No matter what I do, the Macbook does not sense the TV as a second monitor anymore.
I took the MacBook Pro to the Apple Store, and their "genius" there had it working fine with a DVI connection to a regular monitor. The Panasonic TV I have has HDMI connections and one VGA connection which does not support HD, but no DVI option. I want an HD connection to mirror or extend my MacBook Pro screen. At the Apple Store, they didn't have a Thunderbolt/Mini DisplayPort to HDMI adapter, so he could not try that out for me.
Anyone else have this configuration or another similar one with a Panasonic HDTV?
Ideas? Suggestions? Anything?! Help!!
P.S. I'm running Mountain Lion, if that wasn't already obvious. Everything is up to date in my App Store as well.
Thanks!

Hi There,
I have had the exact same issue but with a projector.
The issue lies with Mountian Lion 10.8.2.
I tried many a combination with no luck to get HDMI working.
Took my mac into the apple store and came to the conclusion it was the software, so I asked them to install 10.8 onto it (this is destructive so a backup is a must)
Bought my macbook home and voila, now displaying through my projector.
There is a small graphics update after 10.8.1 which seems to be the cause.
Hope this helps.
Thanks.

2. I reloaded software from my user with original disks (Oct, 2010) and got Mail 4.3 again. Mail 4.3 did not work with latest OS. I am unable to load Mail. Gives Yellow error message.
" You have Mail version 4.3 (1081/1084). It can’t be used on Mac OS X Version 10.6.7 (Build 10J869). For more information, click the Help button."
3. Tried to update software and look for update for mail 4.3 on Apple site to no success.
Hate to go to MS-Entorage ( I may need to learn something new and alien) mail program since contracts are in Mail/Address Book.
Ideas?
