High availability xMII server configuration copy

We are setting up two xMII servers in a Hight Availability configuration. What files/directories do I need to ensure are copied between the main and backup servers so that the configuration is completely duplicated between them? I know I can copy the entire Lighthammer directory but that is kind of a brute force method. What is the more elegant approach?

Please refer to the
<a href="https://www.sdn.sap.comhttp://www.sdn.sap.comhttp://www.sdn.sap.com/irj/servlet/prt/portal/prtroot/com.sap.km.cm.docs/library/uuid/30f43a39-be98-2910-9d9c-a59785f44e41">xMII Best Pratices Guide</a>
Please also note the file SystemConfig.xml found in LighthammerIlluminatorConf
contains the Security Server URL of the machine.

2012 R2 - Clustering High Availability File Server

Hi All
What's the difference between creating a High Availability Virtual Machine to use as a File Server and creating a 'File Server for general use' in the High Availability Wizard?
Thanks in advance.

Hi All
What's the difference between creating a High Availability Virtual Machine to use as a File Server and creating a 'File Server for general use' in the High Availability Wizard?
Thanks in advance.
What's your goal? If you want to have file server with no service interruption then you need generic SMB file server built on top of a guest VM cluster. HA VM is not going to work for you (service interruption) and SoFS is not going to work for you (workload
different from SQL Server and / or Hyper-V is not supported). So... Tell what do you want to do and not what you're doing now :)
For a fault-tolerant file server scenarios see following links (make sure you replace StarWind with your shared storage specific, I'd suggest to use shared VHDX). See:

Hope this helped :)
StarWind VSAN [Virtual SAN] clusters Hyper-V without SAS, Fibre Channel, SMB 3.0 or iSCSI, uses Ethernet to mirror internally mounted SATA disks between hosts.
The goal is a file server that's as resilient as possible. I need to still use DFS namespace though. Its on a Dell VRTX server with built-in shared storage.
I'm having issues getting the High Availability wizard for General Purpose File Server to see local drives :(
So I'm just trying to understand the key differences between creating one of these and a hyper-v server with file services installed.

High availability SQL Server requirements for Remote Desktop Services in Windows Server 2012

Good night,
Thanks for reading this question, I do not write much English.
I am implementing Remote Desktop Services in Windows Server 2012, I need to know the size of the database to create and feature on the .mdf and .ldf, I searched in different microsoft link but I have not received a response.
Kindly appreciate your cooperation and attention.

Hi Alejandro,
I am implementing Remote Desktop Services in Windows Server 2012, I need to know the size of the database to create and feature on the .mdf and .ldf
If you want to know the size requirements of .mdf abd .ldf files, since they are parts of SQL database, I suggest you refer to SQL forums below to get more professional support:

High Availability Production Server using online replication

Hi
In One box, stopped online replication from one box to second box located in remote ofsite. Converted code page conversion from EBCDIC code to ASCII code and then performed Upgrade SAP 4.6C with SAP ECC 5.0. Everything ran smoothly.
Secondly Customer wanted to to do online replication. For this purpose there are two options,
First Option is:
Install SAP ECC 5.0 in second box
Second Option is Homogeneous copy from One box to Second box.
I am not sure which option is better.
After that, we have to start online replication to transfer journal receiver from one box to second box and apply it to the database in Second box.
I am not familiar the OS400 iseries V5R3M0 command how to perform Online replication .
COuld you please send us procedure how to perform Online replication .
Thanks and Regards
A Prasad Rao
After that we have to start

Hi TCS-Support,
I would say, it is always a bit a pitty, to do consulting and to not know the specials of a platform :-((
You can use both ways - installation or homo-copy. I would use the homo copy, but that is my feeling - and in the end you need in order to refresh the stuff a new DB-Copy anyway.
Then you need either iASP, manual apply of journal receivers or to buy a product like Mimix, DataMirror etc. of the HA-Suites.

JCo Server High Availability

How can I make the JCo server implement "High Availability" functionality. The SAP Server which the makes calls to the JCo Server is HA-aware. So if there is a failover, the SAP Server switches over to the other instance but the JCo server keeps sending the message "Server unavailable". Is there a solution for this problem.
Thanks.

Single Appliance not necessarily means Single Point of Failure, an appliance with HW Redundancy could handle failure and provide High Availability, if only configured well.
Does Symantec BrightMail Appliance provide such redundancy configuration?
You will have to ask their support or in a Symantec Forum.

RAID 1 is not showing in UCS Server configuration utility

Hi,
I have a UCS Server C200 M2 Rack Mount and planning to install Windows 2008 R2 server in it. To make it High Available, i m configuring RAID 1 in it.
I can easily configure RAID from BIOS setup and after rebooting it shows me that the RAID 1 is found and Online in status.
Once I insert the Cisco UCS Server Configuration Utility 2.0 CD and try to check the RAID Configuration, it show me error message "SCU is unable to detect a RAID controller in the server"
If I move further to install OS then during installation setup gets hang and system reboots.
I attached the screen shot for review and help.
Kindly advise!
Thanks,
Aman

Hi Aman,
Can you download the Driver package from
http://www.cisco.com/cisco/software/release.html?mdfid=283860950&flowid=25801&softwareid=283291009&os=Windows%202008%20R2%20(x64)&release=1.3(1.1)&relind=AVAILABLE&rellifecycle=&reltype=latest
And extract w2k8r2_intich10r_13.21.0614.2010.zip for the Intel ICH10R integrated RAID controller.
Try Browsing to this Driver either from the SCU or during the direct OS reinstall and make sure
"Hide drivers that are not compatible with hardware on this computer" is unchecked to be able to point to the Driver
I assume you are seeing the problem as described in the RAID configuration issues in
http://www.cisco.com/en/US/docs/unified_computing/ucs/c/ts/guide/TS_2Server.html
Installing Windows 2008 64-bit and RAID controller had issues.
LSI drivers are not bundled in Windows 2008 64-bit. These must be installed during the installation process. During the install process, if the hard drives fail to be detected, use the load driver option to point the drives to the correct drivers for the LSI controller in the system. The drivers can be loaded using a USB drive. When loaded, the hard drives are displayed and the hard drive for the OS can be selected.
Please let me know how the installation goes.

NCS Appliance Ver 1.1.1.24 VM High availability disk options

Hello,
I currently am running an NCS appliance running version 1.1.1.24. I am looking to set up a VM server as a redundant High Availability backup server. Per the config guides the VM server needs to be set up with identical physical specifications as the appliance. That means I will need to set a vm up with the following specs:
CPU: 2 x Intel Xeon Processor (2.4-GHz 12-MB Cache)
•Memory: 16-GB (1×2-GB, 2Rx8) PC3-10600 CL9 ECC DDR3
•Network Interface Cards: 2 x 10/100/1000 Gigabit
The config guide for the VM recommends that I start with a minimum 400Gb disk space. Does anyone have experience deploying a VM as a backup for an appliance? Does this sound correct?
Thanks,

Grid Control 12c and high availability databases

Hello,
In the context of high availability databses, my configuration is as follow:
2 AIX servers on 2 sites with shared storage -> Site1 and site2.
During normal operations databases are on site1. In case of disaster, databases can fallover on site2.
On my Grid Control, 2 agents are installed: One for AIX on site1 and one for AIX on site2.
Databases have been discovered on AIX:site1
Listener is a virtual address and can also fallover.
What are the possibility on the grid side ?
Do I have to discover also the databases on site2 ?
Actually, Listener is seen down on the site who has not the databases.
Is there a way to only configure the Listener virtual address on the Grid ?
Regards

Hi,
Basically you have to relocate the targets to the new agent (the one installed on site2). I haven't done that, but I expect to work fairly easy and smooth. Refer to the following section of Cloud Control 12c manual:
Configuring Targets for Failover in Active/Passive Environments

Need to add a second weblogic server for high availability

I have a weblogic 10.3.3 server with forms and reports 11.1.1.3.
I have an adminServer, WLS_FORMS and WLS_REPORTS managed servers setup.
This was setup with the wizard, so the WLS_FORMS is in the cluster_forms cluster group and WLS_REPORTS in the cluster_reports group.
I now need to add a second server with forms and reports also to act as one big server and provide high availability and load balancing.
How do I achieve thsi, is there a wizard that will do this?
The two servers are setup in exactly the same way, with the same versions of Weblogic and Forms and Reports.
Thanks in advance.

I do not know "reports 11.1.1.3" application, but from your description this application is already targeted on a clustered configuration.
So it should be sufficient to add 2 new instances in the WebLogic domain "WLS_FORMS_2", "WLS_REPORTS_2", include them into the existing clusters and add a load balancer (like apache + wleblogic-plugin) that will balance requests on instances.
I never heard of wizards to create such clustered environments. However it is not hard to do:
1- Install binaries on the new machine
2- Create the domain configuration directory on the new machine using config.sh wizard in the same way you have aleady done with the first machine.
In this step you can create a clone of the existing domain, but it is enough to create a domain with the same name and the same admin instance.
Instead of using config.sh, you can also copy the domain directory from the existing machine and change diretories in scripts if needed.
The domain configuration is needed only to find the binaries, the basic domain files common to all installations, and to allow startup scripts (see point 4-) to connect to the admin and download the domain/instance configuration.
3- Configure the new instances on the existing WebLogic console
4- Create startup scripts for "WLS_FORMS_2", "WLS_REPORTS_2" on the second machine

High availability for file server and exchange with 2 physical servers

Dear Experts,
I have 2 physical server with local disks only. I want to setup below on same with high availability, please advise best prossible options. We will be using windows 2012 R2 Server..
1. Domain controller
2. Exchange 2013
As of now I am thinking of setting up below:
1. Install Hyper-v on both and create 3 VM on each as
-On Host A- 1 VM for DC, 1 VM for File server with DFS namespace and replication for file server HA and 1 VM for Exchange 2013 with CAS/MBX with DAG and DNS RR for Exchange HA
-On Host B - 1 VM for ADC, 1 VM for File server DFS member for above and 1 VM for Exchange 2013 CAS/MBX with DAG member
I have read on internet about new features called scale out file server (SoFS) in Windows 2012 Server but not sure that will be preferred for file sharing.
Any advise will be highly appreciated..
Thanks for the help in advance..
Best regards,

Best regards,
DFS is by far the best way to implement any sort of file server. Because a) failover is not fully transparent and does not happen always (say not on copy ) b) DFS cannot replicate open files so if you edit a big file and have node rebooted you're going to
lose ALL transactions/updates you've applied c) actually slows down the config. See:
DFS for failover
http://help.globalscape.com/help/wafs3/using_microsoft_dfs_for_failover.htm
DFS FAQ
http://technet.microsoft.com/library/cc773238(WS.10).aspx
(check "open files" point here)
DFS Performance
http://blogs.technet.com/b/filecab/archive/2009/08/22/windows-server-dfs-namespaces-performance-and-scalability.aspx
SoFS a) requires shared storage to run and you don't have one b) does not support generic workloads
(only Hyper-V and SQL Server) and c) technically makes sense to expand SAS JBOD or existing FC SAN to numerous Hyper-V clients over 10 GbE w/o need to invest money into SAS switches and HBAs and FC HBAs and new licenses FC ports. Making long story short:
SoFS is NOT YOUR CASE.

http://www.aidanfinn.com/?p=12786
http://www.aidanfinn.com/?p=12786
For now you need to find some shared storage to be a back end for your hypevisor config (SAS JBOD from supported list, virtual SAN from multiple vendors like for example StarWind see below, make sure you review ALL the vendors) and then you create a failover
SMB 3.0 share for your file server workload. See:

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..

Hyper-V 2012 High Availability using Windows Server 2012 File Server Storage

Hi Guys,
Need your expertise regarding hyper-v high availability. We setup 2 hyper-v 2012 host in our infra for our domain consolidation project. Unfortunately, we don't have hardware storage that is said to be a requirement that we can use to create a failover cluster
for hyper-v host to implement HA. Here's the setup:
Host1
HP Proliant L380 G7
Windows Server 2012 Std
Hyper-V role, Failover Cluster Manager and File and Storage Services installed
Host2
Dell PowerEdge 2950
Windows Server 2012 Std
Hyper-V role, Failover Cluster Manager and File and Storage Services installed
Storage
Dell PowerEdge 6800
Windows Server 2012 Std
File and Storage Services installed
I'm able to configure the new feature about Shared Nothing Live Migration - i'm able to move VM's back and fort between my hosts without storage. But this is planned and proactive approach. My concern is to have my hyper-v host to become highly available in
the event of system failure. If my host1 dies, the VMs should go/move to host2 and vice versa. In setting this up, i believe i need to enable the failover clustering between my hyper-v hosts which i already did but upon validation, it says "No disks
were found on which to perform cluster validation tests." Is it possible to cluster it using just a regular windows file server? I've read about SMB 3.0 and i've configured it as well i'm able to save VMs on my file server, but i don't think that my hyper-v
hosts are already highly available.
Any feedback and suggestions or recommendation is highly appreciated. Thanks in advance!

Your shared storage is a single point of failure with this scenario so I would not consider the whole setup as a production configuration... Also setup is both slow (all I/O is travelling down the wire to storage server, running VMs from DAS is ages faster)
and expensive (third server + extra Windows license). I would think twice about what you do and either deploy a built-in VM replication technologies (Hyper-V Replica) and apps built-in clustering features that does not require shared storage (SQL Server and
Database Mirroring for example, BTW what workload do you run?) or use some third-party software creating fault tolerant shared storage from DAS or investing into physical shared storage hardware (HA one of course).
Hi VR38DETT,
Thanks for responding. The hosts will cater a domain controller (on each host), Web filtering software (Websense), Anti-Virus (McAfee ePO), WSUS and an Auditserver as of the moment. Is the Hyper-V Replica somewhat give "high availability" to VMs or Hyper-V
hosts? Also, is the cluster required in order to implement it? Haven't tried that but worth a try.

URL to be used in high availability for Directory Server

Hi All,
I have an environment configured for high availability. I have two OVD and OID servers each in this environment, configured in high availability. What should be the value in the Server URL field of the Directory Server IT Resource in the OIM for this environment? In the normal environment, I had it as "ldap://ovdhost01:6501" and it was working fine. But since there are two servers here, I am not sure what URL to use in place of this. The entry for the two ovd hosts in the OHS is "idstore.com" which is configured on 6501 port. But I tried using the following URLs and none of them worked:
1. idstore.com
2. ldap://idstore.com
3. ldap://idstore.com:6501
4. ldap://ovdhost01:6501,ldap://ovdhost01:6501
Can someone help me know the correct URL to be used in this case?
Thanks,
$id

Not sure about OVD or OID but for SOA and OIM:
SOA:
XMLConfig -> XMLConfig.SOAConfig -> SOAConfig
Rmiurl -> t3://soahost1:soaport1,soahost2:soaport2
Soapurl -> Load balancer or web server url (without the /workflow context)
OIM:
XMLConfig -> XMLConfig.DiscoveryConfig -> Discovery
OimFrontEndUrl -> Load balance or web server url (without the /oim context)
And ofcourse on your LB or WebServer, you need to configure these:
SOA: http://docs.oracle.com/cd/E23943_01/core.1111/e10106/ha_soa.htm#CHDDJEGD
OIM: http://docs.oracle.com/cd/E21764_01/core.1111/e10106/imha.htm#BGBDFEIE

Transaction Log Truncate not working on Sql Server 2012 High Availability Groups

Hi Everyone
Firstly I have tried to search the forum for similar issues but can't seem to find any that match our situation.
We have a SQL Server 2012 High Availability Group with 2 Nodes
Node 1 = Primary
Node 2 = Secondary
Backup Schedule as follows
Full Database Backup @ 00:00
Transaction Log Backup every 30 minutes from 00:30:00 till 23:59:59.
These backups are run by Maintenance Jobs, but we have also tried doing direct backups in SSMS using Backup Database and Backup Log commands.
Before we configured the High Availability group the transaction log backups worked fine.
After we configured the High Availability group we performed a Full Backup and the T-Log schedule did the T-Log backup. The 1st T-log backup truncated the log (Used space Decreased) as expected.
However subsequent T-Log backups do not truncate the T-Log.
This happens both in our acceptance and Live environments. This also happens when running the backups as a Backup operator and sysadmin, this does not seem to be a permissions issue at all.
We have tried running the Backup on the Primary and Secondary Replica.
What about High Availability groups could stop Transaction Log Backups from not truncating the log?
Thanks
James

WebLogic Server clusters not high available!!

          I'm working with WebLogic Server 6.0.
          I try to connect to cluster using explicit IP addresses.
          For this case,first ,I cluster server A,B and C ,then client try to look up home
          interface at server A.
          After server A return home reference ,client creates EJB object and calls method
          using that reference .
          If server A fail, it still working with others server ,B and C.
          But if new client try to find home reference at server A ,he can't.
          This situation means that WebLogic Server cluster is not high availability or
          I did something wrong with configuration?
          And if I missed something ,how can I fix it?
          Thanks for your attention.


Hi King,
          If you look up at a non-existent IP/port, then it will not respond. That is
          expected behavior.
          You should not be using an explicit IP like that. At least use DNS round
          robin.
          Peace,
