Pattern for multi-server environment

Hi All,
Here's our scenario:
1) We have a network whose nodes are all server-capable.
2) A dedicated server is not possible.
3) Only one node can act as a server at any one time.
4) The nodes are actually operators' terminal (eg, with data entry/editing facility).
5) When the active server goes down, another node will take-over.
6) If the previously downed server goes up again, it will again take-over. It will also acquire the data from the previous server/s.
7) A node may be used offline. But if it join the network, it should give it's data to the server.
Do you know a pattern/s I can use in this setup? Any help would be deeply appreciated.
TIA
mat

You should probably do some research on failure/recovery models and election protocols.

When we go for shared Server environment?

When we go for shared Server environment from Dedicated server mode?
When we have to choose thi shared Server mode?
Which is the optimized way?

> When we go for shared Server environment from Dedicated server mode?
You do not. It is not one or the other - it is using both correctly. You want shared server sessions to service applications (any, from web/app servers to flat clients) that are OLTP in nature. They fire off short-and-sweet SQLs that takes a second or three to execute.
A shared server pool of a few processes can service a very large number of clients.
You want to use dedicated servers to service OLAP type clients. They fire off complex SQLs that can tie up the server processes for several minutes at a time.
And that in a nutshell is how to apply the two. It is not Shared Servers versus Dedicated Server. It is about using The Right Tool For The Job. Nothing more and nothing less.
As for Windows, I will not really bother quickly with shared server connections. On Windows both shared and dedicated servers runs as threads in the main Oracle executable process image.
There is thus very little resource saving by reducing the number of threads as the footprint of a thread is tiny in comparison to a brand new process. The amount of resources saved by a reducing the number of dedicated server threads is not significant. If anything, Oracle on Windows has shown to scale better than Oracle on Linux in this regard. (refer to [url http://www.perftuning.com/pdf/Comparison_Oracle_Windows_Linux.pdf]A Comparison of Oracle Database 10gR2 Real Application Cluster Performance on Microsoft Windows 2003 Server Enterprise Edition x64 and Red Hat Enterprise Linux x86_64 from the Performance Tuning Corporation).
And this is exactly the opposite of how Oracle behaves on Unix. Each server process is a physical kernel process. This means that a servicing a 1000 concurrent sessions with a 1000 dedicated server processes, each consuming memory and resources, are expensive. Conversely, supporting a 1000 concurrent sessions with a 100 shared server processes is (almost) 90% cheaper.
This makes Shared Server a desirable option to use to scale OLTP sessions on Unix-based systems (or any platform where Oracle does not use multi-threading but multi-processing).
PS. As the Linux kernel support Posix threads (see http://en.wikipedia.org/wiki/Native_POSIX_Thread_Library), it begs the question as to when Oracle is going to support multi-threading on Linux instead of multi-processing.. or at least give us the option to choose.

Workflow Custom Activity deploy in multi server environment

I have been working on a project that involves developing a custom workflow activity for SharePoint 2013. I am developing it in a single server environment working with http.
My problem occurs when deploying to multi-server environment with https (WFE, APP). My question is how to deploy my solution to the new environment.
The steps:
Create a project - c# activity library
Add a workflow activity, add .xml
Deploy the .dll and .xml of project to:
"C:\Program Files\Workflow%20Manager\1.0\Workflow\Artifacts" "C:\Program Files\Workflow Manager\1.0\Workflow\WFWebRoot\bin"
net sotp "Workflow Manager Backend"
net start "Workflow Manager Backend"
Deploy .DLL to GAC
- Created MSI using install shield in VS2010 to add .DLL to GAC
- Verify .DLL in GAC by going to c:\windows\assembly and %windir%\Microsoft.NET\assembly
iisrest
Deploy WSP to SharePoint, activate feature, open SharePoint Designer 2013 and choose the custom action that now appears when creating a 2013 workflow
To recap we have workflow manager on the APP server and and the workflow client on the WFE. We deployed the .DLL and .XML to the workflow manager (APP) only. The .DLL is deployed
to/in the GAC on the WFE and the APP. We are able to see and create the activity in Designer 2013 and we deploy the workflow to a normal SharePoint list. When we run the workflow we do not get any errors in the ULS logs, event viewer or Workflow Manager Debug
Logs (event viewer also). The site is not created though. We believe the issue is that the custom C# (.DLL) is not being ran.
This all works fine and dandy on my single server environment. Workflow is working like a charm. How can we trouble shoot what the issue is if we are not finding any errors?
Is there a step that we missed or some other place we need to look for logs? Would the ULS logs show the site creation or show running our custom code? Currently it does not show anything when we run the workflow.
Let me know if this is unclear or if anyone needs more information. Thanks

Hi,
Here is a workaround for your reference:
We can develop a custom WCF service instead of the Custom Activity in SharePoint. And then use the service from workflow. It use a separate dedicated server for workflow without having any reference to SharePoint DLLs from inside workflow.
Here is a similar thread for your reference:

Multi-server Environment without Windows Domain

Hi,
Has anyone had experience with installing SAP BPC in a multi- server environment without using Microsoft Active Directory as a domain. (ie just using local users for everything).
Do we need to create a domain in order in successfully install and use the BPC? If that is the case, which server is best suited to install the domain on?
Many thanks

Hi,
Do you have at least a domain for hosting your servers ? Without an administrative domain for computer and technical accounts I doubt you could even make BPC work in a multi-servers environment.
If you don't have a domain for your users, you may (but i will never recommend it), create all your users localy. But you will have to create them on all BPC servers with same name / same password. Password adminisration will be a real mess as you will have to change the password on all machine each time the user want to change it. And this will not be done by the end-user but by IT staff. Also, users will not be able to use Windows Integrated Authentication functionnality.
So basically, yes use a domain for computer and users. The most easy architecture is to use a single domain for both computer and users.
If you have to install a Windows AD, I would take a look at Microsoft white paper and KB. But I think that you have to dedicate at least 1 machine for it (best is to have 2 servers for fault tolerance).

Task executions in multi server environment

Hi All,
I have a question regarding the task execution in a multi-server environment.
Below is the scenario:
We have two SIM applications: one for intranet users (employees and contractors) and one for extranet users (customers). Both these applications point to same database repository.
Intranet : idm-intra.ear ( this is deployed on IntraServer1 and IntraServer2)
Extranet: idm-extra.ear ( this is deployed on ExtraServer1 and ExtraServer2)
And both share same repository WAVESET.
Now we are deploying some request workflows for intranet users. In our case even the extranet application can see these tasks.
My question is: if I triggered a request workflow from intranet application and it is pending for approval and when it times out, is there a chance that this workflow is executed by the "extranet" application?
Thanks,
kIDMan.

The answer to your question is yes. If you go to the Configure>>Server tab in the admin console on any of these instances of IdM you should see all four instances. An easy way to test this is happening, is to enable workflow tracing and launch a couple of request from IntraServer1. IdM will try to distribute the work among all the servers it knows about so you'll see portions of the flow within the workflow traces on the individual servers. Well maybe it's not an easy thing to test because it's a timing issue.......
I had an issue recently in which the guy doing the build to the QA environment messed up and pointed the QA IdM instances to the DEV repository. We were doing some testing of some flows on DEV and they were being executed on the QA IdM instances and bombing out with ClassNotFound errors because the QA environment was not build out completely/correctly. So even though the requests were being launched from the DEV instances they were being executed on the QA instances.
There is a feature that is supposed to let you restrict which workflows run on which servers. If you go to the admin console and click on Configure>>Servers choose a server and click on the 'Scheduler' tab and then check the 'Task Restrictions' checkbox. From here you can restrict which workflows run on which servers. But my suspicion is that this doesn't work correctly (based on some testing I was doing on 7.1)....might want to test it out....Hope this helps.

Best Method For Server Variables in Multi-Developer / Multi-Server environment?

In addition to having a development environment on my laptop and my desktop, we have a staging server and a production server. Furthermore, we have one or more developers and contributors who may have one or more development environments of their own.
Each of these environments may have their own copy of ColdFusion (developer, standard, enterprise - whatever is needed) and their own copy of SQL Server / Express / whatever, their own data source name, data user name, data password, names for CF Mappings, and so forth. So, while the SQL tables and directory structure of the code is all the same, there are many things different from one to the next.
Certainly, we need to have a large number of variables so when someone uploads via SVN commit they don't screw everyone else up because they shove their own local names into place.
How do YOU handle that? XML file? CFC? some form of .INI file? Looking for a solid way to handle this for a myriad of developers and environments, so I welcome seeing YOUR solution.
Thank you!
RLS

BKBK,
Thank you for the response.
We considered a databased-solution, but if we keep all of the variables in a database and our datasource in CF contains the user/psw, then it's increasingly easy for any hacker to reach into our bag of jewels. If you don't store the user/psw in CF, then all of your developers have easy access to the db user/psw and that's not easy to change when each one leaves.
One of the most compelling solutions we have found is http://code.google.com/p/configcfc/ By using an XML file and designating it as do-not-upload in the svn local files for each developer, each developer can maintain their own list of variables with the values customized to their environment, and when they push updates they don't have to worry about flipping switches or making changes to what the source or destination location is. Furthermore, being an XML that actually ends with ".cfm" means that it cannot be read by the typical hacker.
BTW, for anyone who hasn't discovered SVN in conjunction with Dreamweaver when working in a multi-programmer environment, man, you're missing out. The one place that Adobe needs to finish this, though, is the final step -- migration from your staging server to production. Anyone with clues on that will earn my undying gratitude (for whatever that's worth!).

Oracle Spatial over a distributed, multi-server environment

Our organisation has a multi-site, multi-server distributed environment. As we are looking to implement Oracle Spatial in this environment are there any issues regarding distribution / replication, backup & recovery we should be aware of ?
Any advice / comments would be welcome.

Hello Soulis,
Before Oracle 9i, replication and distribution do not work with Objects.
There are no known issues with backup/recovery that we know of, nor are there any major issues with import/export.

Assign request to another BizTalk Server in Multi server environment.

We are having 2 biztalk server in load balance, when one server goes down the request already assigned to that server gets stuck in Active mode only when the server comes up they get process, can I assign those request to the other biztalk server without
waiting for the server to come up.
Regards, Dharm Raj

Is your Host(s) represented by Host Instances on both BizTalk Servers? Also are all Host Instances running?

Deploy Exchange 2013 Edge Transport Server for multi-site environment

Hi,
I have a multi-site Exchange 2013 environment. The configurations are as below.
Active Directory Sites and Exchange Servers.
SiteA - EXMB1 & EXCAS1
SiteB - EXMB2 & EXCAS2
SiteC - EXMB3 & EXCAS3
All sites are connected via VPN. (Good speed. No latency issues)
All the three Mailbox Servers are in DAG. Only one mailbox database. All servers running Exchange 2013.
I am planning to deploy Edge Servers in the infrastructure (I am doing it for the first time). Normally, it will be in DMZ.
Now, I can deploy 2 Edge Servers for reliability.
Question.
1. Can I deploy 2 Edge Servers and create subscription to all the mailbox server in 3 different site? Or, is it like one edge server can make subscription to only mailbox servers in one Active Directory Site? I am not sure about this and could not find much
information from TechNet.
One Edge Server can make subscription to all 3 mailbox server in 3 sites. Similarly, I can make the subscriptions in the second edge server as well. Configure 2 external MX records with the same priority so that there will be some load balancing.
Also, in such a case if the mailbox database become active from a different site, I need not make any new changes to the Edge Servers right?
2. If the first way is not correct, I will have to deploy 1 Edge Server each for each of the Active Directory Site. (In DMZ only, not in domain)
Make Edge Subscription to the mailbox server in corresponding site.
Make 1 MX record and point it to the Edge Server which is subscribed to the Mailbox Server from which the Database is Active. The problem is, every time will have to change the DNS record when ever the database copy is activated from a different mailbox
server. And the issues with propagation.. delay..
I am not sure which of the above 2 ways will work. Appreciate suggestions from anyone who have previous experience with similar infrastructure.
Thanks in advance. :)

Hi
One or more Edge Transport servers can be subscribed to a single Active Directory site. However, an Edge Transport server can't be subscribed to more than one Active Directory site. If you have more than one Edge Transport server deployed, each server can be
subscribed to a different Active Directory site. Each Edge Transport server requires an individual Edge Subscription.
A subscribed Edge Transport server is associated with a particular Active Directory site. If more than one Mailbox server exists in the site, any of them can replicate data to the subscribed Edge Transport servers.
I don't think there is a solution to subscribe edge servers for more than 1 site. Edge Servers can be scoped only to one site.

Web Agent and Clip Board set up for multi user environment

Hi
Our environment is
Database: 0racle8.1.5 on Sun Solaris
Currently we are not using OAS but a portal server and Apache
Intermedia Web Agent and Clip Board are working fine.
The questions are
1. if there are multiple users (content managers) who would be adding /modifying content in the database, the how can I go about with Clip board.
2.The requirement is these people should be able to search documents on the basis of keywords. So how do we integrate Intermedia query capabilities on this clip board interface.
3. For production level how do we go about implementing.
Should we continue to have the ctxsys user and use that itself.
Thank you for any solutions

Use of SQL Reporting Services in BPC (multi-server environment) - concept

Hello Experts,
I have the following scenario:
2 BPC application servers. Lets call them BPCA1 and BPCA2.
Load Balancer with virtual name BPCA
SQL 2005 database server BPCDB
Database server would hold BPC databases and Report Server database - requires 1 SQL Server license.
Each application server requires SQL Server Integration Services to be installed - 2 SQL Server Standard Edition licenses in my scenario.
Now, is Reporting Services a required component and needs to be installed on both application servers?
Because "scale-out" deployment for Reporting Services is only supported in SQL Server Enterprise Edition. Price difference between Standard and Enterprise Editions are quite sufficient.
So, can I install SQL Server Reporting Services only on BPCA1 and point BPC configuration to BPCA1 for all applications servers?
What is the use of SQL Server Reporting Services in BPC besides running Admin Reports?
Thanks in advance,
Akim

Hi RS is not required to be installed into db server or app server. It can be even an external RS server.
You are right if you will try to install RS in both app server you need Enterprise Edition because is required by Microsoft for RS web farm.
If you will install RS into database server then you don't need other license for SQL but if you will use SQL Server 2005 you have to install IIS into database server.
For many companies this broke some security policies and for this reason you have to install RS into appserver.
If you will use SQL Server 2008 then IIS is not required anymore and this is another plus in favor of SQL 2008.
Also SAP recomendations is to use SQl Server 2008 for SAP BPC 7.0 SP3 or later becaiuse the performances are better.
RS is used for:
Admin reportts. Audit Reports Journal Reports.
But without RS working you can have issue also with some Admin components not really just with reports.

BPC 7M SP6 - best practice for multi server setup

Experts,
We are considering purchasing new hardware for our BPC 7M implementation. My question is what is the recommended or best practice setup for SQL and Analysis Services? Should they be on the same server or each on a dedicated server?
The hardware we're looking at would have 4 dual core processors and 32 GB RAM in a x64 base. Would this adequately support both services?
Our primary application cube is just under 2GB and appset database is about 12 GB. We have over 1400 users and a concurrency count of 250 users. We'll have 5 app/web servers to handle this concurrency.
Please let me know if I am missing information to be able to answer this question.
Thank you,
Hitesh

I don't think there's really a preference on that point. As long as it's 64bit, the servers scale well (CPU, RAM), so SQL and SSAS can be on the same server. But it is important to look also beyond CPU and RAM and make sure there's no other bottlenecks like storage (Best practice is to split the database files on several disks and of course to have the logs on disks that are used only for the logs). Also the memory allocation in SQL and OLAP should be adjusted so that each has enough memory at all times.
Another point to consider is high availability. Clustering is quite common on that tier. And you could consider having the active node for SQL on one server and the active node for OLAP (SSAS) on the other server. It costs more in SQL licensing but you get to fully utilize both servers, at the cost of degraded performance in the event of a failover.

SSRS configuration in multi server environment with SSL

Hi
I have read numerous articles on configuration of Reporting Services in SharePoint integrated mode but not able to figure out if I'm missing something.
Environment description
SharePoint Enterprise 2010
2 web servers, 2 app servers, 1 DB server.
Authentication is custom claims (not windows claims)
Since SSRS does not work in Custom Claims (confirmed by MS in ticket), we extended the webapplication. The URLs are
https://actualurl (custom claims)
https://EWAURL (Windows NT and Extended Web Application)
Reporting Services Add-In has been installed on 2 web and 2 app servers.
Reporting Services is running on app01 server. When we access
http://app01/reportserver we get list of site collections. However when we try to create a new Report Source in
https://EWAURL we get exception. Exception has both certificate error and SSRS SOAP exception. SSRS URL is not SSL enabled.
My question is:
Does SSRS work when it is running only on one app server? Or do I need to install reporting services on all app and web servers and then configure them to the app01 Reporting DB?
Due to limitations we are trying to use one app server as reporting server.

My apologies
I thought I was creating this in SharePoint 2010 - Setup, Upgrade, Administration and Operations.
@Admin/Moderator: could you please change this to the correct forum

GRC AC 5.3 Logging strategy in multi server nodes

Hello Experts,
We have GRC AC 5.3 SP6 and 5.2 10 landscapes and PRD system are running with multiple server nodes. SAP recomends to use SAP Logger instead of Java Logger in multi server environment, but i am not able to find out complete documentation on this.
Can someone please give pointers on configuring GRC logging in NWA - which all Categories needs to be defined,etc,etc.
And after this configuration, will we be able to see the logs of scheduled jobs with same details as shown in GRC --> Background Job -> View Logs.
Thanks
Davinder

Hello Harleen,
Thanks for your time. Here are my observations
1. When we have created categories and then deinfed Logging and Tracing (with Severity level ALL) in NWA - these entries have also been reflected in Visual Administrator -> Log Configuration.
2. We will have to restart SAP system after changing logging strategy from Java Logger to SAP Logger.
3. After this change and restart, only upcoming new jobs scheduled/run will be displayed in NWA, jobs ran in the past will never be displayed in NWA.
Severe Problems faced when checking logs through NWA:
1. Logs through NWA are not at all readble as one entry is displayed in one row, whereas checking logs in RAR - VIew Logs was very convenient (similar to reading a text file).
Is it possible to customize the display format of log files in NWA to something like text files,etc?
2. When we try to donwload the logs from NWA, server produces huge dumps files of size in GBs (hpfa files which are memory dumps) - and before this download is completed - server crashes after around 15 minutes of starting log downloads - no free space availbale as everything has been taken by these memroy dumps (around 7GB).
Any further pointers on handling GRC AC logs (multiple server nodes) in NWA would be highly appreciated.
Thanks
Davinder
