Failover server?
Is there a way to set up the JNLP file to specify a failover server in case the primary server is unavailable? It looks like I have to customize the JNLP file for each server we use for downloads (in the <jnlp codebase="http://...">).
I'm also guessing that if I tell my users to go to a different server when the primary is unavailable, they will end up with a duplicate set of JAR's underneath the alternate server's entry in the cache. True?
It would be nice if I could specify a mirroor server to go to when the first is unavailable. Any thoughts on how to tackle this?
This has also become an issue for me - I'm using webstart at a large corporate client. Ideally you want to be able to tell a cached jnlp to use an alternate codebase if the first one fails.
Is there any way to hook into the jnlp read step on the client using an extension - so that the client could use an alternate codebase?

Adding a failover server in Unity 7.0(2) messaging only environment
Were are using a single Unity 7.0(2) server (messaging only) with Exchange and the message store running on the same server. We want to introduce a failover server in the invironment.
I originalloy built the server using the "istallation Guide for Cisco Unity Release 5.x in a Voice Messaging Configuration with Microsoft Exchange (Without Failover)" instructions.
I have two questions:
Can I convert the existing server to a failover configuration with out having to rebuild it from scratch?
My next question is, since the documentation I'm reading states that the message store must be on the secondary server, is there a way to migrat the message store over?
Thank for any help.

Thanks for the reply and this looks like it might be my problem. Question though, I see there is an option in advanced settings tools to exclude return reciepts from voice mail stack but I do not see the registry key. Do I need both or will changing it in advanced tools be sufficient?
Thanks,

Can I failover a DHCP failover server?
Greetings,
I'm in the process of putting together an enterprise wide DHCP design. I'm planning on leveraging the hot failover feature in Server 2012. I'll be using a hub-and-spoke topology with a server in our primary datacenter acting as the failover partner
for all the DHCP servers at branch offices.
My question is can I failover the failover server? Basically can I configure the failover partner for all the primary servers to fail over to yet another DHCP server in a secondary datacenter?
Thanks!One line answer to your question is no. Since a given scope on a DHCP server can be part of one and only one failover relationship and given that all the scopes on your Hub DHCP server are part of different failover relationships distributed across
your spoke servers you cannot make those scopes a part of failover relationship with another DHCP Server.
Having said that, in case your hub DHCP Server fails the spoke DHCP servers can take over. Yet if you are concerned about data loss then you can have appropriate disaster recovery\backup solutions in place to safeguard the DHCP data on the hub server. -
Coldfusion licensing for failover server
I'm interested in setting up a passive failover Coldfusion server. Since the failover will only receive requests if the other server is down, can I use the same license across both servers?
CF licence terms can be found from here in other section:
http://www.adobe.com/legal/licenses-terms.html
PDF refer to section 1.8 which mentions disaster recovery.

Hi,
I have a Problem with DHCP Failover in Windows Server 2012
We configured 2 Windows Server 2012 with DHCP Role and created a Scope with loadbalancing algorithm.
The Problem is, that the two DHCP Servers Show different statistic Information. DHCP 1 has 254 addresses and 218 in use. DHCP Server 2 has 254 addressses and 187 in use.
We found situations when one DHCP Server has no available IP addresses and the other one has about 40% available addresses.
Why do the Servers have different available address spaces ? We have one scope with one class c net, 254 addresses.
Our Szenario is with this config not high available, cause of sometimes running out of IP addresses on one DHCP Server.
Thanks for help

Björn Schiemann LemonTec IT Systems KG htttp://www.lemontec.deHi Bjoern,
Would you please provide us your detailed load balance configurations.
In load-balance mode of operation both the servers respond to client requests. Here’s how the servers ensure the distribution of client requests between themselves:
Each DHCP server on receiving the client request calculates hash of the MAC address in the client request as per hashing algorithm specified in RFC 3074. Each server hashes any MAC address
to a value between 1 and 256. If the load distribution ratio between the 2 servers is left at the default of 50:50; and if the hash of the MAC address falls between 1 and 128 then the first server will respond to the client request else if the hash is any
value between 129 and 256, the other server responds to the client. This ensures that only one server responds for a specific client. If the load distribution ratio has been changed by the admin to a different value, the distribution of hash buckets would
be in that proportion. The admin does not need to configure the MAC addresses on any server configuration a-priori.
Quote from DHCP Failover Load Balance Mode
http://blogs.technet.com/b/teamdhcp/archive/2012/08/06/dhcp-failover-load-balancing-mode.aspx
In addition, I notice that you have a Class C network for the scope, why does each DHCP server have 254 IP address available?
Thanks.

Failover server (using config.xml)
Hi ,
I am using weblogic server 7.0(1) installed in solaris . I installed a new server where i need to have same configuration as like (1) .
so i directly placed the config.xml of (1) in the second server domain by changing the IP address in config.xml.
I am getting the following at the start of server..

DB2 database doesn't start on FailOver server in HA
Hi Experts,
We have a sap cluster under AIX 6.1 and DB2 , during failover the database may not able to start.
is only hold on
db2start <-- waiting more than 3 hr no and reply.
db2stop <-- waiting more than 3 hr no and reply.
db2stop force <-- still cannot kill the db2
db2_kill <-- still cannot kill the db2
But when I restart the AIX again (shutdown -Fr) , then the db2 work
fine ( no any problem )
Could you advise how can I solve the db2 the issue ?
p.s. we had checked other failover case is no any problem
e.g.
1. move cluster service using smit cl_admin
2. remove the network cable physically
( problem case )
2012-02-17-19.28.45.875329+480 <-- is the time haven follow case
NodeA : standby mode ( only start the DI )
NodeB : holding the SAP ( CI and ACSC )and DB2 cluster services
thx,
Tony

Cold-Failover with Oracle Weblogic Server 10 R3
Hi ALL,
It is possible to configure cold-failover using Oracle Weblogic Server?/
- 2 instances with the same ip, if one fails the second will run
- Not comunication between nodes like in normal cluster
ThanksHello All,
Have anybody configured auto server migration for cold failover?
I have a few questions regarding this setup, any help is much appreciated.
1. for the floating ips to work, do I need 2 NICS and two cables on each server?
2. Do I have to configure 2 different ips on one interface, which will be used as node manager listen address's for each of the 2 machines?
3. What will be the listen address of each of these servers(primary server & failover server)? Is it the floating ip address? or empty (all local addresses)?
4. can we start both the primary server & failover server so when primary goes down, the failover will be quick?
Thanks,
Chandra -
Hi,
Does anyone have any experience with clustering OS X Server or running mirrored mail/web servers with OS X Server?
I have a mail server and a web server that I want to "double up". I want one to run as the primary mail/web server but, in the event of the primary failing, I want the other to take over.
Ideally, I'd like to have two OS X Servers running in different geographic locations (and thus on different public IP addressing schemes) so I would imagine that DNS may be involved.
Any input appreciated.
Thanks,
StuartIdeally, I'd like to have two OS X Servers running in different geographic locations (and thus on different public IP addressing schemes) so I would imagine that DNS may be involved.
You're opening up a whole can of worms. Are you ready for this?
Let's start with the easy one - web service.
The first issue is one of content replication.
Is your web content static? i.e. a series of static .html pages and images? or is it dynamic (uses database-driven content, for example)?
If it's static content, then a periodic rsync might be sufficient. If it's dynamic, though, you have a whole other set of issues to deal with - how to replicate your data to the second site and how you manage fallback (when you want to go back to the main site)
Some database engines (such as MySQL) include replication technology which might be sufficient for you, but you'll need some MySQL skills to set it up.
Next comes mail. For the most part here I recommend evaluating how long you expect to run in the secondary site. If it's a number of hours then don't bother.
The reason I say this is because the cost of fallback is high here. If your main mail server is at location A and you failover to location B you have all kinds of issues in synching mailboxes (messages that came into user X's mailbox on server B need to be merged into his mailbox on server A - a file-based sync is not sufficient).
SMTP (the mail transport protocol) has significant fault-tolerances built-in. If your server is offline for several hours remote mail servers will just queue up the messages, retrying periodically until the mail goes through or a timeout expires (typically 3 days).
Even if that isn't sufficient for you, you can setup multiple MX records in DNS, each with a different priority. Now your mail server in location B can accept mail for your domain but only on a store-and-forward basis (it holds the mail indefinitely, until server A comes back online). In this way you don't have the issue of mail being filtered into mailboxes that need to be synched.
This does mean that your users won't get mail for a while (until either server A comes back up, or you kick server B into full mail server mode instead of store-and-forward), but at least no mail will bounce.
Once you have those elements worked out the actual failover process typically involves changing DNS zone data to include your failover addresses (unless you're running some fancy load balancing option that handles this in real-time). How long it takes people to get the failover addresses and start using the failover server depends on many factors, not least the TTL on your zone data.
If your TTL is 24 hours, for example, then anyone who looked up your address in the previous 24 hours will use their cached response (server A) and not notice the failover address until the TTL expires.
Most people get around this by using a lower TTL. This means you get more hits to your DNS server since people aren't caching replies as much. You need to balance TTLs and server load against failover time. -
Removing Meeting Place 6 Audio Server Failover Configuration
Hi, I have an old MeetingPlace 6 system.
Issue - Intermittently users are getting static and dead-air experience. Looking at Call Manager CDR, the call is trying to route to offline audio server. I verified the IPGateways for failover Audio server configuration and did not find so.
Requirement - I would like to remove the failover configuration sine failover server is offline
Considerations - How do I do this? What do I have to consider?
Thanks in Advance,
AmishHi Andrew
I have looked at both the suggestions from you and jdedell12.
1. Shadow Server - there is nothing configured
2. H.323 on CUCM - I have two IP GW's configured. Nothing else relevant to Shadow server.
3. IP GW's - Checked GW SIM config
Interestingly enough, after the Audio server power cycle the issue fixes itself.....I have had this issue twice in the past 9 weeks....random behaviour.
If this occurs again, I am going to reconfigure the GW SIM in the IP GW's. Since IP GW's route the calls, I am thinking that there may be a bad configuration issue here. This is going to be the next area for look out.
Thoughts?
Thanks guys

Database Mirroring and Replication in SQL Server 2008 R2
I have configured the mirroring and replication between 4 servers (A,B,C,D).i.e, Mirroring between A to B and C to D, Replication between A and C. The configuration was a success and I am able test the replication(B to C) when I have failed over the mirroring
dbs(A to B). The replication works fine after the mirroring fail over but I am not able to check its status in the Replication monitor. When I am having any insert in a table which is replicated in B, it is reflected back to C..it means the replication is
working fine.
Any thought on how I can view the status of replication from mirrored server. I tried adding the publisher in the monitor, but no luck. If I check the snapshot agent status, it says could not retrieve the info, same with the log reader agent status.
Any suggestions on this please.
Thanks, SiriFor example in your case...
Server A is principal and Server B is Mirror with either Manual or Automatic Failover.
Server A is replicated to Server B ( publisher & B is subscriber )
In Server A Database named Test_Mirror_Replication is configured for both mirroring and Replication.
Now you have failed over your Database 'Test_Mirror_Replication' from Server A to Server B.
After the Failover Server A will act as Mirror for DB 'Test_Mirror_Replication' & Server B will act as Principal for DB 'Test_Mirror_Replication'
Hope my understanding is correct ?
If yes then have you tried monitoring the replication after registering in other instance with current principal database sql instance name ? I mean current Publisher database name sql instance ? not your old sql instance name which was before the mirroring
role change or failover...
Hope you are trying with mirror database server name ?

Files don't open or will only open 'Read Only'. Server reboot resolves issue for 1 day
Greetings!
We have a SharePoint 2010 Foundation server that I recently inherited. I'm a novice at SharePoint, but let me cut to the chase.
Users have recently (within the last week) started experiencing a problem where if they open a file, it will error either saying that the file cannot be opened, or it will only open in read only. This occurs with Excel, Word, Power Point docs. They CAN however,
open and edit these documents in the browser with web apps. After launching the full office application, if they click 'Edit Document', it will appear to switch to editable mode, but the title bar will still contain 'Read Only' and they can't save changes
directly back and are forced to do a 'Save As'. The only thing I have been able to do to remedy this is to quiesce the server and reboot it. After reboot, it will work until something magical happens overnight and it's broken again the next morning. I'm trying
to hunt down what this magical event is but could use some help.
Note that after I reboot the server, users can access and modify normally, no rebooting of workstations or closing of any applications (including the browser that's already on SharePoint) for it to start working, so I believe we can eliminate an endpoint
issue.
Server Specs:

SQL DB Hosted remote on a SQL 2008 R2 server running on Windows 2008 R2. The SQL database is set up in a mirror configuration.
I'm sure I missed a lot of pertinent information but want to get something out there. Thanks in advance.There are warnings that repeat every ~1hour and one critical that occurs daily. Under each error, I added notes of what I've done to remedy.
Warning, Event ID 14
The start address sts4://serveraddress/contentdbid={0d061a04-5c82-48e5-b381-e111d1926b8d} cannot be crawled.
Context: Application 'Search_index_file_on_the_search_server', Catalog 'Search'
Details:
The SharePoint server was moved to a different location. (0x8004fd12)
I found in central management that the content database is pointing to an old SQL database but the failover server is set correctly. I assume that is what is generating this but I don't know how to fix it.
Warning, Event ID 2138
The SharePoint Health Analyzer detected a condition requiring your attention. Drives are at risk of running out of free space.
Available drive space is less than five times the value of physical memory. This is dangerous because it does not provide enough room for a full memory dump with continued operation. It also could cause problems with the Virtual Memory swap file:
(SERVERNAME- C:\).
Examine the failing servers and delete old logs or free space on the drives. For more information about this rule, see "http://go.microsoft.com/fwlink/?LinkID=142688".
I Resolved this already an hour ago, extended the HDD from 100GB to 250 GB and made pagefile 2x the RAM (it was set to 8GB, RAM is 16GB)
Critical, Event ID 6398
The Execute method of job definition Microsoft.SharePoint.Administration.SPTimerRecycleJobDefinition (ID b71cb245-29cf-49d5-a157-2c04b881f15f) threw an exception. More information is included below.
The timer service was not recycled because the following jobs were still running: Microsoft SharePoint Foundation Usage Data Import
The timer recycle job was set to run no earlier than 6am and no later than 6am. I manually ran the job and it completed. I set the times for it to run to be 4am - 8am to give it time to run.
This was right after a reboot (barf of the errors below)

MCS7825I5-K9-UCC2 redundant server
Hi we have a client using:
a) MCS7816I5-K9-CMD2 as Call manager server, and on "CCM Node licenses feature" they have one used license and one remaining license.
b) MCS7825I5-K9-UCC2 as Unity server.
Our client is asking for a backup proposal, and we have a pair of questions.
1) Where we can verify if current MCS7825I5-K9-UCC2 server has support for a second Unity node??
2) MCS7825I5-K9-UCC2 has an EOL/EOS report, and its recommended sustitute is MCS-7825-I5-IPC1, but this server does not come with Unity pre installed software. So we need to verify which software component is required to implemet a Cisco Unity backup server for this client.
Thanks a lot for your help.

Database MIRRORING in SharePoint 2010 - What to do in absence of Witness server
Hi,
Our environment is divided in 2 DC's, DC1 has our database cluster(2 nodes) and the DC2 has our mirroring server.
Now as part of DR test, DC1 will be shut down. So our Mirrored server in DC2 should cater all requests. To achieve this, I have set "Failover Server" for our content DBs, service application DBs from Central Admin > Manage Content DB/Service
Application. I will set failover server for Config DB using Powershell. However I DONOT have "witness server" in place.
Now here are the things which I need help on:
1. Once I set "Failover Server" for content DB in Central Admin, where can I see these changes? I mean where is that config file where this change is set?
2. As we do not have a Witness Server, what all steps will be followed manually to achieve this failover?You do not need to use a SQL Alias when implementing mirroring, or failing over to the mirror.
You simply need to update each database's FailoverServer value, e.g.:
$db = Get-SPDatabase | where {$_.Name -eq "SharePoint_Config"}
$db.FailoverServer = "SQLMirroringPartner"$db.Update()
All databases should have this parameter and can be handled in this way (some databases, such as Usage and Sync, aren't recommended to be mirrored as they hold transient information).
To failover, you will manually initiate bringing the secondary online via SQL Server Management Studio.
