Symantec Antivirus Best Practice for Hyper-v 2012 R2 Cluster

Hi Team ,
I am Working with Hyper-v 2012 R2 Cluster with 5 Node . All are working fine .
Now i am Planning to install Antivirus Symantec in to each node. Please let me know if there is any Best practice guide to install Symantec Antivirus for Hyper-v 2012 R2 Cluster node.
I am using full version of Windows 2012 R2 with hyper-v.
Thanks

I would also look strongly at no antivirus as well, but if you do, here are the recommended exclusions and possible issues with Anti-Virus to look out for.
Look for the Hyper-V section:
http://social.technet.microsoft.com/wiki/contents/articles/953.microsoft-anti-virus-exclusion-list.aspx
Big things to stay away from from a VM level too:
1. Do not have a set time when all VMs will kick off a scheduled full disk scan. This can create an I/O storm on your hosts as well as saturate the CPUs as well. Look for products or settings that allow for randomization of full disk scans on
the VMs or do not do full disk scans and only keep the real time scanners active on the VMs for incoming writes.
2. Watch for Antivirus products that update all the VMs at the same time. Again, sometimes you can randomize or exclude a scheduled full disk scan, but sometimes an automated update that kicks off say at 12am can then automatically kick off a
mini scan. This can also create disk I/O and CPU storms.
The problem that still exists with many Antivirus products today is that they try to scan as fast as they can and then get out of the way. This works ok for endpoint desktops or laptops, but when you have 50 or more VMs on a host all ramping up trying
to get done as quick as they can, then this can cause some issues.

Symantec antivirus Best practice for oracle database on windows server 2003

Hi all,
I have an oracle database server on windows server 2003 platform of version 10.2.0.4. what would be best practice of running symantec antivirus on that server as well as database file exclusions from scanning them.
My server had rebooted unexpectedly for many times. in event log i have id as 6008. what may be cause of it..?

Normally, you don't run a virus scanner on a database server because your database server isn't vulnerable to viruses. It's behind firewalls, people aren't reading mail on it, people aren't plugging thumb drives into it, etc. If you do decide that you need to run a virus scanner on a database server, at least exclude the Oracle data files from the scan. Oracle gets very unhappy if someone else tries to open its data files (or, worse, if someone opens a data file before it gets the chance to acquire exclusive access).

Best practices for deploying forms in a 'cluster'?

Anyone know of any public docs that discuss typical best practices for
- forms deployment;
- forms apps management and version control; and/or
- deploying (and keeping) the .frm/frx in sync when using multiple forms servers in a HA or load balancing envrionment?

Hi adil,
Based on your description, you want to know the best practices for search service in a SharePoint farm.
Different farms have different search topologies, for the best search performance, I recommend that you follow the guidance for small, medium, and large farms.
The article is about the guidance for different farms.
Search service can run with other services in the same server, if condition permits and you want to have better performance for search service and other services including BI performance, you can deploy search service in dedicated server.
If condition permits, I recommend combining a query component with a front-end Web server to avoid putting crawl components and query components on the same serve.
In your SharePoint farm, you can deploy the query components in a WFE server and the crawl components in an application server.
The articles below describe the best practices for enterprise search.

Best Practice for Distributed TREX NFS vs cluster file systems

Hi,
We are planning to implement a distributed TREX, using RedHat on X64, but we are wondering which could be the best practice or approach to configure the "file server" used on the TREX distributed environment. The guides mention file server, that seems to be another server connected to a SAN exporting or sharing the file systems required to be mounted in all the TREX systems (Master, Backup and Slaves), but we know that the BI accelerator uses OCFS2 (cluster file systems) to access the storage, in the case of RedHat we have GFS or even OCFS.
Basically we would like to know which is the best practice and how other companies are doing it, for a TREX distributed environment using either network file systems or cluster file systems.
Thanks in advance,
Zareh

I would like to add one more thing, in my previous comment I assumed that it is possible to use cluster file system on TREX because BI accelerator, but maybe that is not supported, it does not seem to be clear on the TREX guides.
That should be the initial question:
Aare cluster file system solutions supported on plain TREX implementation?
Thanks again,
Zareh

BEST PRACTICE FOR THE REPLACEMENT OF REPORTS CLUSTER

Hi,
i've read the noter reports_gueide_to_changed_functionality on OTN.
On Page 5 ist stated that reports cluster is deprecated.
Snippet:
Oracle Application Server High Availability provides the industrys most
reliable, resilient, and fault-tolerant application server platform. Oracle
Reports integration with OracleAS High Availability makes sure that your
enterprise-reporting environment is extremely reliable and fault-tolerant.
Since using OracleAS High Availability provides a centralized clustering
mechanism and several cutting-edge features, Oracle Reports clustering is now
deprecated.
Please can anyone tell me, what is the best practice to replace reports cluster.
It's really annoying that the clustering technology is changing in every version of reports!!!
martin

hello,
in reality, reports server "clusters" was more a load balancing solution that a clustering (no shared queue or cache). since it is desirable to have one load-balancing/HA approach for the application server, reports server clustering is deprecated in 10gR2.
we understand that this frequent change can cause some level of frustration, but it is our strong believe that unifying the HA "attack plan" for all of the app server components will utimatly benefit custoemrs in simpifying their topologies.
the current best practice is to deploy LBRs (load-balancing routers) with sticky-routing capabilites to distribute requests across middletier nodes in an app-server cluster.
several custoemrs in high-end environments have already used this kind of configuration to ensure optimal HA for their system.
thanks,
philipp

(Request for:) Best practices for setting up a new Windows Server 2012 r2 Hyper-V Virtualized AD DC

Could you please share your best practices for setting up a new Windows Server 2012 r2 Hyper-V Virtualized AD DC, that will be running on a new WinSrv 2012 r2 host server. (This
will be for a brand new network setup, new forest, domain, etc.)
Specifically, your best practices regarding:
the sizing of non virtual and virtual volumes/partitions/drives,
the use of sysvol, logs, & data volumes/drives on hosts & guests,
RAID levels for the host and the guest(s),
IDE vs SCSI and drivers both non virtual and virtual and the booting there of,
disk caching settings on both host and guests.
Thanks so much for any information you can share.

A bit of non essential additional info:
We are small to midrange school district who, after close to 20 years on Novell networks, have decided to design and create a new Microsoft network and migrate all of our data and services
over to the new infrastructure . We are planning on rolling out 2012 r2 servers with as much Hyper-v virtualization as possible.
During the last few weeks we have been able to find most of the information we need to undergo this project, and most of the information was pretty solid with little ambiguity, except for
information regarding virtualizing the DCs, which as been a bit inconsistent.
Yes, we have read all the documents that most of these posts tend point to, but found some, if not most are still are referring to performing this under Srvr 2008 r2, and haven’t really
seen all that much on Srvr2012 r2.
We have read these and others:
Introduction to Active Directory Domain Services (AD DS) Virtualization (Level 100),
Virtualized Domain Controller Technical Reference (Level 300),
Virtualized Domain Controller Cloning Test Guidance for Application Vendors,
Support for using Hyper-V Replica for virtualized domain controllers.
Again, thanks for any information, best practices, cookie cutter or otherwise that you can share.

Best Practices for Setting up a Windows 2012 R2 STD Domain Controller in a Remote Site

So I'm looking for an article or writeup similar to the "Adding Domain Controllers in Remote Sites" TechNet article but for Windows Server 2012 STD R2. Here is my scenario:
1. I want to setup the domain controller at Site A where the primary domain controller is located. The primary domain controller is Windows Server 2008 R2.
2. Once the DC is setup I plan on leaving it on our network for a few days before shipping it to remote Site B for installation
Other key items:
1. The remote Site B will have a different IP range than Site A but will be connected to Site A via a single VPN tunnel. All the DCs that replicate with each other are on the same domain.
2. The 2012 DC that I setup for Site B (same domain in same forest) will be a DHCP, DNS, and WSUS server all replicating to the primary DC at Site A
Questions:
1. What items can I setup while it's at Site A without effecting or conflicting with the existing network and domain controller? Can I setup a scope once the DHCP role is added?
2. All of our DCs replicate through Sites and Services, do I have to manually add this to our primary DC for the new DC going to remote Site B? Or when does this happen automatically when I promote the DC?
All and all I'm just looking for a list of Best Practices for 2012 or a Step by Step Guide. Any help would be appreciated.

Hi,
Thanks for your posting.
When you install AD DS in the hub or staging site, disconnect the installed domain controller, and then ship the computer to the remote site, you are disconnecting a viable domain controller from the replication topology.

Best practice for RDGW placement in RDS 2012 R2 deployment

Hi,
I have been setting up a RDS 2012 R2 farm deployment and the time has come for setting up the RDGW servers. I have a farm with 4 SH servers, 2 WA servers, 2 CB servers and 1 LS.
Farm works great for LAN and VPN users.
Now i want to add two domain joined RDGW servers.
The question is; I've read a lot on technet and different sites about how to set the thing up, but no one mentions any best practices for where to place them.
Should i:
- set up WAP in my DMZ with ADFS in LAN, then place the RDGW in the LAN and reverse proxy in
- place RDGW in the DMZ, opening all those required ports into the LAN
- place the RDGW in the LAN, then port forward port 443 into it from internet
Any help is greatly appreciated.

Hi,
The deployment is totally depends on your & company requirements as many things to taken care such as Hardware, Network, Security and other related stuff. Personally to setup RD Gateway server I would not prefer you to select 1st option. But as per my research,
for best result you can use option 2 (To place RDG server in DMZ and then allowed the required ports). Because by doing so outside network can’t directly connect to your internal server and it’s difficult to break the network by any attackers. A perimeter
network (DMZ) is a small network that is set up separately from an organization's private network and the Internet. In a network, the hosts most vulnerable to attack are those that provide services to users outside of the LAN, such as e-mail, web, RD Gateway,
RD Web Access and DNS servers. Because of the increased potential of these hosts being compromised, they are placed into their own sub-network called a perimeter network in order to protect the rest of the network if an intruder were to succeed. You can refer
beneath article for more information.

Best Practice for Tranport request Naming

Hi,
We are using SolMan 4.0 during implementation of ECC 6.0.
We have placed the blueprint and we are in configuration phase.
We have a IMG project created in the DEV system and was assinged in Solution Manager project under System Landscape->IMG Projects.
Now that consultants are going to dev system and customizing they are creating their transport requests.
Is there any best practice for the naming convention or the transport requests..
By creating one IMG project for entire implementation is that going to create any problem..!!
Please sgugest.
Thanks & Regards

As per MSFT best practices(Mentioned by Scott) keep it short as much as possible. You can use SP for SharePoint-SUBSite
also check this blog for best practices.
http://www.networkworld.com/community/blog/simple-naming-conventions-improve-end-user-experience-sharepoint-sites
also one more thing you should consider, never use the reserved words into the SharePoint URLs. you will able to create the site/lis/library/folder but when you browse get the 404 errors.
check this blog:

Best practice for Error logging and alert emails

I have SQL Server 2012 SSIS. I have Excel files that are imported with Exel Source and OLE DB Destination. Scheduled Jobs runs every night SSIS packages.
I'm looking for advice that what is best practice for production environment.Requirements are followings:
1) If error occurs with tasks, email is sent to admin
2) If error occurs with tasks, we have log in flat file or DB
Kenny_I

Are you asking about difference b/w using standard logging and event handlers? I prefer latter as using standard logging will not always data in the way in which we desire. So we've developed a framework to add necessary functionalities inside event handlers
and log required data in the required format to a set of tables that we maintain internally.

Best Practice for SUP and WSUS Installation on Same Server

Hi Folks,
I have a question, I am in process of deploying SCCM 2012 R2... I was in process of deploying Software Update Point on SCCM with one of the existing WSUS server installed on a separate server from SCCM.
A debate has started with of the colleague who says that the using remote WSUS server is recommended by Microsoft because of the scalability security that WSUS will be downloading the updates from Microsoft and SCCM should be working as downstream
server to fetch updates from WSUS server.
but according to my consideration it is recommended to install WSUS server on the same server where SCCM is installed... actually it is recommended to install WSUS on a site system and you can used the same SCCM server to deploy WSUS.
please advice me the best practices for deploying SCCM and WSUS ... what Microsoft says about WSUS to be installed on same SCCM server OR WSUS should be on a separate server then the SCCM server ???
awaiting your advices ASAP :)
Regards, Owais

Hi Don,
thanks for the information, another quick one...
the above mentioned configuration I did is correct in terms of planning and best practices?
I agree with Jorgen, it's ok to have WSUS/SUP on the same server as your site server, or you can have WSUS/SUP on a dedicated server if you wish.
The "best practice" is whatever suits your environment, and is a supported-by-MS way of doing it.
One thing to note, is that if WSUS ever becomes "corrupt" it can be difficult to repair and sometimes it's simplest to rebuild the WSUS Windows OS. If this is on your site server, that's a big deal.
Sometimes, WSUS goes wrong (not because of ConfigMgr)..
Note that if you have a very large estate, or multiple primary site servers, you might have a CAS, and you would need a SUP on the CAS. (this is not a recommendation for a CAS, just to be aware)

Best practice for licence server for RDS Farm & Certificate errors

Hello,
I am in the process of creating an RDS farm using Server 2008 R2. I have three Session Hosts and a Connection Broker.
I have a set of 10 user CALs available and also another 20 on our current RDS server which will need migrating once we go live with the farm.
I understand the User CALs need to be installed on another Server 2008 R2 and I am wondering what is best practice. We are running on an entirely virtual environment and it would be simple enough to create another server and install the CALs on there.
The only issue with that is that I would need to create a replica of this new machine for DR purposes, but this would take up valuable space which may not be necessary.
We are planning on creating replicas of one of the Session hosts and the broker for DR, so I am guessing I would need to install some CALs on the Session Host which is going to be replicated.
There are a few options and I am just wondering what is the best way to go about things.
Also, as an aside, I am getting an annoying certificate error each time I log a test user onto the RDS farm - I think this is because I am using the DNS alias of the RDS Farm to log on. Is there an easy way to get around this, other than the 'Do not show
this message again'. I have been doing some research and the world of Certificates is very confusing!!
Thanks,
Caroline
C.Rafferty

Hi Caroline,
Firstly for your License related issue, you can perform the step on any VM or can create the new VM as replica for RDSH server also. But please be sure that you have installed RD License server on it, activate it and then install RDS CAL on it. But be safe
if possible don’t install RD License server with RDCB, please make that out of it as little away. As you can also install RD License server with AD or make replica of that and install RDL on that.

What’s the specified certificate error which you are receiving?
If you're going to allow users to connect externally and they will not be part of your domain, you would need to deploy certificates from a public CA. In meantime you can refer blog for getting insight for certificate case.

HTML and CSS Best Practices for Eloqua?

Hello Topliners Community,
My name is Ben and I am a Web Designer. I am currently looking for any guidance on HTML and CSS best practices when working with Eloqua. I am interested in the best practices for e-mail and landing pages.
Thank you,
Ben

Personally I like to upload my custom created html/css into Eloqua instead of using the WYSIWYG.
But if you must then right clicking on text boxes and click edit source is the way to go.
There was a good discussion on editing your forms with CSS:

Seeking advice on Best Practices for XML Storage Options - XMLTYPE

Sparc64
11.2.0.2
During OOW12 I tried to attend every xml session I could. There was one where a Mr. Drake was explaining something about not using clob
as an attribute to storing the xml and that "it will break your application."
We're moving forward with storing the industry standard invoice in an xmltype column, but Im not concerned that our table definition is not what was advised:
--i've dummied this down to protect company assets

What is a best practice for this type of table? Yes, we intend on registering the schema against an xsd.
Any help/advice would be appreciated.
-abe

Hi,
I suggest you read this paper : Oracle XML DB : Choosing the Best XMLType Storage Option for Your Use Case
It is available on the XML DB home page along with other documents you may be interested in.
To sum up, the storage method you need depends on the requirement, i.e. how XML data is accessed.
There was one where a Mr. Drake was explaining something about not using clob as an attribute to storing the xml and that "it will break your application."I think the message Mark Drake wanted to convey is that CLOB storage is now deprecated and shouldn't be used anymore (though still supported for backward compatibility).
The default XMLType storage starting with version 11.2.0.2 is now Binary XML, a posted-parsed binary format that optimizes both storage size and data access (via XQuery), so you should at least use it instead of the BASICFILE CLOB.
Schema-based Binary XML is also available, it adds another layer of "awareness" for Oracle to manage instance documents.
To use this feature, the XML schema must be registered with "options => dbms_xmlschema.REGISTER_BINARYXML".
The other common approach for schema-based XML is Object-Relational storage.
BTW... you may want to post here next time, in the dedicated forum : {forum:id=34}
Mark Drake is one of the regular user, along with Marco Gralike you've probably seen too at OOW.
