SharePoint Central Administration: High Availability and Load Balancing

Running Central Administration on more than one server in the farm is 100% supported and indeed a recommended best practice on SharePoint 2010.
Is Load Balancing on Central Administration
supported for SharePoint 2013?
Is Implementing Kerberos Authentication for load balanced Central Administration 100% supported in SharePoint 2013?
Is Implementing Central Administration on Port 80 or 443 100% supported on SharePoint 2013?
I’ve read a article about from Spence
Harbar. I would like to know of this is supported for SharePoint 2013?

High Availability and load balancing

Hi,
I have 6513 catalyst with redundant sup720 and msfc. All the servers are connected to this switch and there is no vlan configuration. Here is the hardware config of the box.
Mod Slot Ports Module-Type Model Sub Stat
1 1 48 10/100/1000BaseT Ethernet WS-X6148-GE-TX no ok
2 2 48 10/100BaseTX Ethernet WS-X6148-RJ-45 no ok
3 3 48 10/100BaseTX Ethernet WS-X6148-RJ-45 no ok
4 4 48 10/100BaseTX Ethernet WS-X6148-RJ-45 no ok
5 5 48 10/100BaseTX Ethernet WS-X6148-RJ-45 no ok
6 6 48 10/100BaseTX Ethernet WS-X6148-RJ-45 no ok
7 7 2 1000BaseX Supervisor WS-SUP720-BASE yes ok
15 7 1 Multilayer Switch Feature WS-SUP720 no ok
8 8 2 1000BaseX Supervisor WS-SUP720-BASE yes
I want to introduce a new 6513 chassis with same knid of configuration. Please help me out to configure these boxes to provide the high availabilty as well as load balancing for the server farm. Do I need to do any thing on the servers in terms of hwardare / software requirment to achieve the objective.
thnaks & regards
shalabh

The config is the same for both switches:
(this will enable port channel bundle, you can specify upto 16 ports..i would recommend 10)
(config-if#)interface range gigabitethernet 1/1-2
(config-if#)Description PORT-CHANNEL Interface
(config-if#)switchport
(config-if#)channel-group 1 mode on
(config-if#)switchport trunk encapsulation dot1q
(config-if#)switchport mode trunk
(config-if#)speed 1000
(config-if#)no shutdown
(Enable SRM SSO)
router(config)#redundancy
router(config-red)#mode sso
router(config-red)#end
router#show redundancy states
you should see my state = active
peer state = standby hot
where are your users come into the 6500's? if they are sitting on the 6500's I would recommend putting them in a separate vlan.

Sharepoint Central Administration appears to not load css or scripts

We have SBS 2011 with Sharepoint and i'm currently trying to enable a few features in the Central Administration. Our companyweb site works great but when logging in to Central Administration all we get is what appears to be raw HTML and background javascript
errors which cause a number of the buttons to not work at all.
I have uninstalled the Central Administration and reinstalled it but the problem persists.
I have checked the permissions at
C:\Program Files\Common Files\Microsoft Shared\Web Server Extensions\14\TEMPLATE\LAYOUTS\1033\STYLES
And everything seems to suggest files are available and security is set correctly.
I've also tried to run in Firefox and Chrome with the same results.
Does anyone have any experience of this issue or where to start troubleshooting it.

Hi ,
Please try re-run the "SharePoint 2010 Products Configuration Wizard" for your SharePoint farm, see if it would fix this issue.

Services missing in SharePoint Central Administration

Hi,
In SharePoint Central Administration -> Application Management -> Manage Service Application.
I could see only the following services
- Application Discovery and Load Balancer Service Application
- Security Token Service Application
- Usage and Health data collection
Rest all the other services are missing.
Please advise how to get all the other missing services back. The Sharpoint is installed on our build server and want to integrate it with TFS. As it is LIVE project server and CI is also configured on it, would reinstalling Sharepoint again on it,
will create some issue/problem for the TFS.
Please help and advise
Thanks
Irfan Khan

Hi,
I understand that you want to get the services on your farm. I can see from your first post that you are looking at the service applications page, not the Services on server page. You need to first check the ‘Manage Services on server’ page. Make sure that
the services you need have already been started. Then you can go to the ‘Manage Service Application’ page to create the service applications.
If you want to use the PerformancePoint Service, you need to make sure that you are using SharePoint 2010 enterprise edition. Check the SharePoint edition here:
Open Central Administration> Upgrade and Migration> Enable Enterprise Feature.
Here you can enter your enterprise version product key to enable enterprise feature.

Central Administration not Available, STSADM password reset errors "job-admin-apppool-change" already exists

Hi Everyone,
I think I've shot myself in the foot by not properly following set up instructions.
I have a two-fold problem. Firstly, my Sharepoint Central Administration V4 site is showing
Service Not Available. This seems to be related to the credentials the
Central Administration V4 Application Pool - hitting Test Settings within
IIS Manager for the site shows an Authentication and Authorization error for the credentials due to a bad password.
My reading indicates that I should run something to the effect of:
%STSADM -o updatefarmcredentials -userlogin DOMAIN\username -password <new password as set via AD>
This runs into the following Error message
Error deploying administration application pool credentials. Another deployment may be active. An object of the type Microsoft.SharePoint.Administration.SPAdminAppPoolCredentialDeploymentJobDefinition named "job-admin-apppool-change" already exists
under the parent Microsoft.SharePoint.Administration.SPTimerService named "SPTimerV4". Rename your object or delete the existing object.
I've tried searching out a solution but as yet have been unable to find a mechanism to resolve this error. I have had a look through http://social.technet.microsoft.com/forums/en-US/sharepointadmin/thread/b7c17dac-1cd1-4f75-a031-e28e4fbfd2f7 but
it doesn't seem to relate to the same problems - as far as I know the account from which the command is being run is a farm administrator and the problem seems to be the existing job rather than permissions errors.
Your help will be much appreciated.
Stuart

Hi Stuart Weaver,
Firstly, please check if the SharePoint 2010 timer service is running. If not, please start it manually, then check the effect. In addition to this, you can try to
run SharePoint configuration wizard, then check the effect.
Note: when you start the SharePoint 2010 timer service, make sure you input the latest password. The steps are as follows:
Open services.msc, locate the SharePoint 2010 timer service, double click it, then click log on tab, input the updated password, then click apply.
Hope this helps.

Hi karabo,
According to your error message, it says that the ajax.dll (Version=5.7.20.2) assembly is missing.
As far as I know, SharePoint Central Administration web application does not refer to the ajax.dll assembly by OOB.
Do you have any custom solution which reference ajax.dll assembly? If so, please undeploy it before your solution is working fine.
Also you can try to copy the ajax.dll assembly to Global Assembly Cache or your Central Administration web application Bin directory.

– Enable high availability and redundancy for Cisco WAAS

How this is available
– Enable high availability and redundancy for Cisco WAAS appliances in data centers.
Thank you.

Hi,
You can serially cluster two WAE devices with the Cisco WAE Inline Network Adapter installed to provide higher availability in the data center if a device fails. If the current optimizing device fails, the inline group shuts down, or the device becomes the overloaded, the second WAE device in the cluster provides the optimization services. Deploying WAE devices in a serial inline cluster for scaling or load balancing is not supported.
More deatils here: Clustering Inline WAEs
Hope this helps.

Data Centre Interconnection - firewall and load balancer deployment

Hi all,
I've read lots of Cisco docs/white papers on DCI - Layer 2 extension between DCs, but as yet I cannot find any decent information on how best to deploy firewalls and load balancers in such a design. I've seen refs to FHRP isolation on Nexus 7k (and possible 6k if you use DCI block) but nothing on the services elements.
The services element seems to be a complete minefield here:
- active/standby across sites, or deploy resilient pairs in each site?
- how to align optimal traffic flows inbound and ooutbound (RHI, SNAT, etc.)
- best practice suggestions ideally.
Cisco DCI docs seem to always gloss over the fact that most customers would have to deal with firewalls and load balancers here, and simply refer to 'coming soon' for that info.
If anyone has any good suggestions/links to docs explaining detailed implementation info would be much appreciate
Thanks
Phil

You might want to check out this new product called ITD.
Simple and faster solution:
ITD provides :
ASIC based multi-terabit/s L3/L4 load-balancing at line-rate
No service module or external L3/L4 load-balancer needed. Every N7k port can be used as load-balancer.
Redirect line-rate traffic to any devices, for example web cache engines, Web Accelerator Engines (WAE), video-caches, etc.
Capability to create clusters of devices, for example, Firewalls, Intrusion Prevention System (IPS), or Web Application Firewall (WAF), Hadoop cluster
IP-stickiness
Resilient (like resilient ECMP)
VIP based L4 load-balancing
NAT (available for EFT/PoC). Allows non-DSR deployments.
Weighted load-balancing
Load-balances to large number of devices/servers
ACL along with redirection and load balancing simultaneously.
Bi-directional flow-coherency. Traffic from A-->B and B-->A goes to same node.
Order of magnitude OPEX savings : reduction in configuration, and ease of deployment
Order of magnitude CAPEX savings : Wiring, Power, Rackspace and Cost savings
The servers/appliances don’t have to be directly connected to N7k
Monitoring the health of servers/appliances.
N + M redundancy.
Automatic failure handling of servers/appliances.
VRF support, vPC support, VDC support
Supported on both Nexus 7000 and Nexus 7700 series.
Supports both IPv4 and IPv6
N5k / N6k support : coming soon

ARFC: Single Server and Load Balancing

Hi All,
I am trying to create aRFC model. In SAP logon screen, I can see two tab pages - Single Server and Load Balancing.
Can you please let me know when we have to use which tab?
Thanks
TG

Single Server Connect or Load Balancing connect is completely independend from the location where SAP Gui Client is installed.
Single Server connect means that your are directly connecting to an ABAP Server using hostname and systemnumber you have to provide.
Load Balancing Connect means that you specify the message server of the central instance of an ABAP Server group. The SAPGUI first connects to the message server which will provide the SAPGUI with the information about the best performing ABAP server. SAPGUI will then connect to this ABAP server.
Single Server is suitable for small landscapes with lets say less than 4 application servers. In huger configurations (and those which I know will grow to more than 3 servers)I would prefer to use logon groups - aka Load Balancing.

SQL Server 2005 High Availability and Disaster Recovery options

Hi, We are are working on a High Availability & Disaster Recovery Planning solution for an application database which is on SQL Server 2005. What different options have we got to implement this for SQL Server 2005 and after we have everything setup how
do we test the failover is working?
Thanks in advance.........
Ione

DR : Disaster recovery is the best option for the business to minimize their data loss and downtime. The SQL server has a number of native options. But, everything is depends upon your recovery time objective RTO and recovery point objective RPO.
1. Data center disaster
Geo Clustering
2. Server(Host)/Drive (Except shared drive) disaster
Clustering
3. Database/Drive disaster
Database mirroring
Log shipping
Replication
Log shipping
Log shipping is the process of automating the full database backup and transaction log on a production server and then automatically restores them on to the secondary (standby) server.
Log shipping will work either Full or Bulk logged recovery model.
You can also configure log shipping in the single SQL instance.
The Stand by database can be either restoring or read only (standby).
The manual fail over is required to bring the database online.
Some data can be lost (15 minutes).
Peer-to-Peer Transactional Replication
Peer-to-peer transactional replication is designed for applications that might read or might modify the data in any database that participates in replication. Additionally, if any servers that host the databases are unavailable, you can modify the application
to route traffic to the remaining servers. The remaining servers contain same copies of the data.
Clustering
Clustering is a combination of one or more servers it will automatically allow one physical server to take over the tasks of another physical server that has failed. Its not a real disaster recovery solution because if the shared drive unavailable we cannot
bring the database to online.
Clustering is best option it provides a minimum downtime (like 5 minutes) and data loss in case any data center (Geo) or server failure.
Clustering needs extra hardware/server and it’s more expensive.
Database mirroring
Database mirroring introduced in 2005 onwards. Database Mirroring maintain an exact copy of a database on a different server. It has automatic fail over option and mainly helps to increase the database availability too.
Database mirroring only works FULL recovery model.
This needs two instances.
Mirror database always in restoring state.

http://www.slideshare.net/rajib_kundu/disaster-recovery-in-sql-server
HADR Considerations
Need to Understand the business motivations and regulatory requirements that are driving the customer's HA/DR requirements. Understand how your customer categorizes the workload from an HA/DR perspective. There is likely to be an alignment between the needs
and categorization.
Check for both the recovery time objective (RTO) and the recovery point objective (RPO) for different workload categories, for both a failure within a data center (local high availability) and a total data center failure (disaster recovery). While RPO and
RTO vary for different workloads because of business, cost, or technological considerations, customers may prefer a single technical solution for ease in operations. However, a single technical solution may require trade-offs that need to be discussed with
customers so that their expectations are set appropriately.
Check and understand if there is an organizational preference for a particular HA/DR technology. Customers may have a preference because of previous experiences, established operational procedures, or simply the desire for uniformity across databases from
different vendors. Understand the motives behind a preference: A customers' preference for HA/DR may not be because of the functions and features of the HA/DR technology. For example, a customer may decide to adopt a third-party solution for DR to maintain
a single operational procedure. For this reason, using HA/DR technology provided by a SAN vendor (such as EMC SRDF) is a popular approach.
To design and adopt an HA/DR solution it is also important to understand the implications of applying maintenance to both hardware and software (including Windows security patching). Database mirroring is often adopted to minimize the service disruption
to achieve this objective.
HADR Options :
Failover clustering for HA and database mirroring for DR.
Synchronous database mirroring for HA/DR and log shipping for additional DR.
Geo-cluster for HA/DR and log shipping for additional DR.
Failover clustering for HA and storage area network (SAN)-based replication for DR.
Peer-to-peer replication for HA and DR (and reporting).
Backup & Restore ( DR)
keep your server DB backups in network location ( DR)
Always keep your sql server 2005 upto date, in case if you are not getting any official support from MS then you have to take care of any critical issues and more..

Web Dispatcher - Reverse Proxy and Load Balancing

I'm finding limited docs on Web Dispatcher with regard to reverse proxy and load balancing. Are you aware of some recent presentations or docs in this area? The info on help.sap.com is not what I'm looking for.
Thanks.

Hi,
best thing is that you look at your scenarios and test the web dispatcher against each of it, like:
- SSL
- Portal only
- Web Dynpro ABAP / Java
- BSP
- Different backend systems like SRM, MDM
- Several backends with 1 Web Dispatcher
After getting a list of use cases that you can test quite easily (installation of Web Dispatcher is done fast and can be done on a local PC), you can contact SAP Support and ask them about the specific problems and questions you encountered. This way, you'll get the official answer, sometimes they will even inform you about "secret" parameters and options.
As of the reverse proxy functionality: there are several version of Web Dispatcher available that differ from the functionality offered. The latest version - 7.2 - is the one that offers the most, i.e. allows you to create rewrite rules like Apache.

Reverse Proxy and Load Balancer for SMP 2.3 and Agentry Application

Hi Expert,
I'm putting in place a mobile solution composed by SMP 2.3 SPS 4 and SAP ECC 6.0. In the SMP 2.3 I created the agentry server and I have deployed my agentry application.
My SMP/Agentry infrastructure is composed by two servers therefore I need a load balancer for balance the load into the several servers. Furthermore I need to use a reverse proxy in my DMZ zone.
Based on what indicated in the SAP note "1904213 - SAP Mobile Platform Server Release Information" the Apache Reverse Proxy is not supported for Agentry clients. Agentry uses nginx for Reverse Proxy.
I also found the following document How-to-Guide for Reverse Proxy and Load Balancing in SAP Mobile Platform 3.x that explain how to set-up a reverse proxy and load balancer with nginx and apache.
Both the SAP note and the HOW to document are refereed to SMP 3.0 and not to SMP 2.3.
I would know if the NGINX must be used also for SMP 2.3.
Any suggestion/information is appreciated.
Thanks in advance
g.
