Mac OS X Server, High Availability, Mac Mini

Hi All,
Currently running Mac OS X Server on a mac mini, I'm looking for some ways to make that mac mini "server" a high availability system for my office.
The first thing i will change is to install the operating system on a external firewire 2 disks RAID 1 hard drive : http://www.lacie.com/us/products/product.htm?pid=10967
Then I'm thinking how to make sure the rest of the mac mini will be running all the time as well.
That's why I'm wondering if it's possible to make everything double : 2 minis with 1 RAID hard drive each.
Each complete set would be linked to create somewhat of fail-over system : If one set woes the other one can take over with exactly the same data.
A bit like what it's been done here :
http://homepage.mac.com/pauljlucas/personal/macmini/cluster.html but with OS X Server instead of Linux.

Hi lulu62-
I am working on a similar project with Minis so I will be keeping an eye on your site.
In addition to Camelot's suggestions, do not forget to have a robust UPS with Automatic Voltage Regulation capable of supporting all of your gear for any expected down time.
The Mini is excellent because you can power it for a long time on a healthy-sized UPS.

Mac OS X Server High Availability

I'm getting two Xserve and a Vdeck for storage. The server will have the basic functions of file and network. I would like to implement a solution in high availability. In the microsoft world, the name is failover cluster.
The files and settings will be in storage. I need the second server performs the functions automatically if the first fails.
Can anyone help me?

There is an IP Failover feature on XServes. Check this article: http://docs.info.apple.com/article.html?path=ServerAdmin/10.5/en/c3fs29.html
It is for Leopard (10.5) Server, though I think that many things did not change.

HTTP Server High Availability

Hello All.
I have a question regarding OC4J and HTTP server High Availability.
I want to do something like the Figure 3-1 of the Oracle Application Server High Availability Guide 10.1.2. See this link
http://download-east.oracle.com/docs/cd/B14099_11/core.1012/b14003/midtierdesc.htm#CIHCEDFC
What I have now is the following:
Three hosts
Two of them are an OAS 10.1.2 which we already configured the Cluster and deployed our applications (used this tutorial: http://www.oracle.com/technology/obe/obe_as_1012/j2ee/deploy/j2eecluster/farmcluster.htm)
Let's say this nodes are:
- host1
- host2
The other one is the Oracle WebCache stand alone (will act as Load Balancer). We will call this
- hostwc3
We already configured the WebCache as Load Balancer and is working just fine. We also configured the session replication successful and work great with our applications.
What we have not clear is the following:
When a client try to visit http://hostwc3/application/ the LOAD BALANCER routes him to, let's say http://host1/application/ and in the browser's URL will not show the Virtual Server anymore (the webcache server) and will show the actual real Apache address (host1 )that is attending him. IF we "kill" on ENTIRE host1 (apache, oc4j, etc..) the clients WILL perceive the down and if they try to press F5, the will try to access to an Apache that doesn't is up and running.... The behavior expected is that the browser NEVER shows the actual Apache URL, so, when some apache goes down, the client do not disconnect (as it happens with and OC4J downfall ) and always works with the "virtual web server".
I came up with some ideas but I want you Guys to give me an advice:
- In Web Cache, do not route for load balancing to Apache, and route the Oc4J directly (Is this possible?)
- Configure a HTTP Server Cluster, this means that we have to have a "Virtual Name"to the Apaches (two of them). Is this possible? how?
- Use the rewrite mode of the Apache. Is this a good idea?
- Any other idea how to fix the Apache "Single Point Of Failure" ?
According with the figure 3-1 ( Link above ) we do can have HTTP Server in a cluster. But I have no idea how to manage it or configure it.
Thanks in advance any help!

You cannot point Outlook Anywhere to your DAG cluster IP address. It must be pointed to the actual IP address of either server.
For no extra cost DNS round robin is the best you will get, but it does have some drawbacks as it may give the IP address of a server you have taken down for maintenance or the server has an issue.
You could look to implement a load balancer but again if you are doing this for high availability then you want more than one load balancer in the cluster - otherwise you've just moved your single point of failure.
Having your existing NAT and just remembering to update it to point to the other server during maintenance may suit your needs for now.
If you can go into more detail about what the high availability your business is looking to achieve and the budget we can suggest the best method to meet those needs for the price point.
Have a great day

HT1338 can i install mac os x server on a mac mini?

I would like to know if i can install a mac os x server on the latest mac mini : http://store.apple.com/us/configure/MD388LL/A?
I just dont see where the 200 USD difference between model goes to ? !!!
Plus I would like to upgrade the RAM to 16gb (using corsair memory) , as apple RAM upgrade is way to much...
Thank you
Alex

The software is no different, you can just purchase server off of the app store. Where the extra money goes for the server mini, is the second internal hard drive. if you are just running a home server or a simple set up of sorts, the app will do you just fine for 19.99.
As with the RAM upgrade. as long as the Corsair memory you have is the same bus speed(1600MHz DDR3), it will work fine.

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.

Exchange server 2013 CAS server high availability

Hi
I have exchange server 2010 sp3(2 MB, 2Hub/Cas) servers.
Planning to migrate to exchange server 2013.( 2 cas servers and 2 mbx servers).
I dont want to go all traffic single so i am keeping the role separate..
In exchange 2010 i achieved hub/CAS high availability through NLB.
In exchange 2013 how to acheive this...

SAP POS - Xpress Server High availability

Dear All,
I have a requirement for Installing "High Availability" for SAP POS XPS server (Store server), Transnet server, & Transnet client.
I have gone thru the possibilities of having Backup server for XPS store server, but the backup server supported by SAP has some major restrictions listed below.
1. Store closing
2. Terminal Closing
3. EOD ( End of the day)
4. Exchange with reciept
5. Layaway sale.
Please let me know whether their is a possibility for achieving high availability for store server which performs the above listed transactions too.
Appreciate if any body can reply asap.
Best regards
Syed

Hello Syed,
Having High Availability for an Xpress is not standards SAP implementation and is quite u201Coverkillu201D. The use of the backup server is designed to allow the store to function and service itu2019s customers until a server can be rebuilt or repaired.
BTW:
-Layaways can be done in offline mode and it will post to the server when it becomes available
-Returns can be done on the backup server if the customer implemented Returns Authorization

How does migrating/restoring Mac OS X Server compare to Mac OS X?

I’m thinking of reinstalling the system software on our server (we have a bunch of problems we can’t get rid of) and I was wondering what the process is like.
We have a Time Machine backup and I was wondering how similar the process is to reinstalling/migrating a client installation of Mac OS X?
For instance does it give you the option to only restore files and data (such as Wiki content), or are you forced to restore all settings, users and preferences as well?
I’d prefer to just restore files and data and then manually recreate users and settings, in the hope of ridding ourselves of some of the problems we have (such as iCal server constantly asking for passwords and an inability to add or remove users using Server Preferences).

It's more a case of looking at the logs and not really knowing what I'm doing. Suffice to say I've taken the trouble-shooting road to my limit.
Mainly we have issues with iCal Server which keeps asking users for their passwords:
http://discussions.apple.com/thread.jspa?messageID=5936657
And now we have this error 14120, since 10.5.6, that causes us not to be able to add or remove users in Server Preferences:
http://discussions.apple.com/thread.jspa?messageID=8773646
I assume by the advice I'm getting from both of you that the migration tool for Mac OS X Server doesn't include the ability to bring only data files over minus all the settings and users?
I'm happy to do a clean wipe. I just want to be sure I can pull across calendars and Wiki data reasonably easily if I do it manually, as I'm not an IT pro. I'm only a CAD Manager and all my knowledge with these things is only through day-to-day experience.

Blocked Incoming FTP from Mac OS X Server Via The Mac Client Firewall

This problem began with Mac OS X Tiger's firewall and lives on in 10.6.2.
Situation:
Anyone with Tiger through Snow Leopard connects to my Mac OS X Server, v10.3. They have 'Passive Mode' OFF in their FTP client. They are 100% successful logging in. Their FTP client sends the LIST command and the server successfully responds with the list data.
But the data can't get into the client's Mac. Why? The Mac OS X firewall BLOCKS IT.
The solution? Nothing sane! You have to turn the Mac OS X firewall OFF. There is NO OTHER SOLUTION.
All the settings on the client machine are perfect. I've been over them a hundred times over the years, tried every single combination possible. So please don't ask or I may bite you.
What's going on: Mac OS X Server 10.3, despite never accepting Passive Mode, sends the LIST data to all client computers in, you guessed it, Passive Mode. The Mac OS X firewall will NOT accept Passive Mode. Result: Catch 22. You can't do it. You are screwed.
Oh, but you could open all the Passive Mode ports in the firewall, and that would work? Be my guest. No way am I going to suggest that horror of a workaround to the hundreds of Mac clients I have accessing my Mac OS X Server.
So Apple, FIX THIS. Integrate FTP Passive Mode into the Mac OS X firewall already!!!

Ok. I was doing something a bit silly. I had the network user and the local user with the same short name. So when they were looked up the local user got preference. So I've fixed all that and am moving huge amounts of data across my humble 802.11g network now. Will have to leave it for a few hours.

Sql Server High availability failover trigger

Hello,
We are implementing sql server 2012 availability groups (AG). Our secondary databases are not accessible in order to save licenses.
We have a lot of issues concerning monitoring, backup and SSIS. They all come down to the fact that they want basic information from the secondary, that is not accessible. We are implementing SSIS, which is supported on AG, but the SSISDB is encrypted.
Backup problem
The secondary instance does not know anything about the backups made in the primary instance. After a failover differential backups fail.
SSIS problem:
There is a blog (http://blogs.msdn.com/b/mattm/archive/2012/09/19/ssis-with-alwayson.aspx) that suggest to make a job that checks whether the status has changed from secondary to primary. If so, you can decrypt and encrypt again.
This job has to be executed every minute. Which is way too much effort for an event that happens once in a while. There are a few other problems with this solution. The phrase "use ssisdb" has to be included in the a job step. And the
jobstep fails. The secondary is not accessible.
Monitoring problems:
We use Microsoft tooling for monitoring: SCOM. Scom does not recognize a non readable secondary and tries to login continuously.
There are a few solutions that I can think of:
- sql server build in failover trigger
- Special status of secondary database.
Failover trigger:
We would like a build-in failover trigger, in stead of a time based job, that starts a few standard maintenance actions if only at the time (or directly after) a failover has occurred. Because now our HA cluster is not really high available until :
- SSISDB works and is accessible after failover
- Backup information is synchronised
- SCOM monitoring skips the secondary database (scom produces loads of login failures)
Does anyone have any suggestion how to fix this?

No built in trigger can achieve your requirement.

Dell PowerVault MD1000 with Mac OS X Server 10.5 (mac pro with fiber connec

Hey Guys. Its time that i add a bulk amount of storage to our mac network.
Currently Our network consists of one mac server which is a Mac Pro with Mac OSX Server 10.5 installed on it with 4 x 750GB Hard Drives with a couple of client machines. I now need to add atleast another 6TB to the network. This needs to be seen as the server as one drive so that 6TB needs to be raid prosume (raid 5)
Now in the Mac Pro server we have a Fibre Card that we dont currently use with 2 slots. My Plan is to buy a Dell PowerVault™ MD1000 (http://configure.euro.dell.com/dells...ulmd1000sata) and put in the amount of hard drives i require into the Dell Storage.
Would this work. If i bought the Dell PowerVault™ MD1000, would i beable to hook this upto the mac server and use it as a storage drive? Although i do no networking. Im still very new to this.
Ideally im looking for something similar to an Xserve Raid, but with out the Apple price tag on the outside if you guys no what i mean.
Best,
Nathaniel

You would at least need a SAS/SATA controller - preferably a hardware RAID one, much like the one bundled with this unit - but it also needs to be OS X compatible.
I would look for something that is known to work, not something you "cobble" together.
The FibreChannel card does you no good if you haven't got a device with FC ports.

What can Xserve and Mac OS X Server do that Mac OS X and .mac cannot?

After repeatedly bumping up against internal and external hard drive storage limits (easy to do with photography and HD video) I am considering an Xserve for storage space and easy access to files. Some of the features of Leopard Server such as iCal Server, email, and IM sound interesting as well. However, I know nothing about server admin, so I am equally worried about 1) getting in over my head and 2) that an Xserve is overkill. Thoughts?
Thanks in advance.

If your concern is storage I'm not sure what you think you'll gain from using an XServe.
The MacPros can handle more internal storage than the XServe, thanks to its four drive bays (vs. the XServe's three).
If you're planning to use the server as a network file store, that's fair enough, but don't think you can do live editing over the network - the throughput is going to be bottlenecked by your network and disk performance over the network is typically much less than local drive. It would be feasible to use it as an archive repository while running the current projects from the local disk, just don't try to edit HD video over the network.
A potentially better solution would be an XServe RAID rather than an XServe - the RAID offers up to 10TB of RAID protected storage which can be directly connected to your workstation, giving you the advantage of local file storage (viable for live editing) without the overhead of the network.
If you do opt for the server route bear in mind that all the other services (email, iCal, IM, etc.) are optional, and you can just ignore them until you're ready to deal with them.

RADIUS Server High Availability?

Hi,
I have two RADIUS servers in my network (one to be the failover serv) and one of them has been having problems, the server is not getting down but the radius service is getting crashed. Don't know why the failover server doesn't respond the authentication for the users if the books said that this is something automatic.
Is there one command to allow the switch to recognize if the service is down in one of the radius servers and automatically use the other one to authenticate the users?.
tks

Hi,
In switches you need to configure two radius server with secret key along with,so as per the sequence in the IOS the request will directed to radius servers.
Below will the command to configure tacas/radius server in switches
tacacs-server host 10.1.x.x
tacacs-server host 10.2.x.x
Hope that help out your query !!

Edge server high availability and next hop to FE servers

Hi All,
As per the article https://technet.microsoft.com/en-us/library/gg412847.aspx "Each Edge Server is a multihomed computer
with external and internal facing interfaces. The adapter Domain Name System (DNS) settings depend on whether there are DNS servers in the perimeter network. If
no DNS servers exist in the perimeter, the Edge Server(s) use external DNS servers to resolve Internet name lookups, and each Edge Server uses a HOST to resolve the next hop server names to IP addresses."
If i have 3 FE servers with DNS load balancing, where the pool.contoso.com would be associated with 192.168.0.1,
192.168.0.2, 192.168.0.3.
How do i create Host record for front end pool in the edge server? i mean which among the 3 ips should i use? as i can use only one IP in the host file record for a host name.
If i create pool.contoso.com
192.168.0.1 and that server is unavailable then the whole purpose of Edge and FE HA is defeated !!

The same doc says: "Edit the HOST file on each Edge Server to contain a record for the next hop server or virtual IP (VIP) (the record will be the Director, Standard Edition server, or a Front End pool that was configured as the Edge Server next hop
address in Topology Builder). If you are using DNS load balancing, include a line for each member of the next hop pool."
But you're right, it was my understanding that only the first line of the hosts file was used. I'd have to presume the application is somewhat intelligent about this or it's incorrect guidance. I've never tested it.
You could use internal DNS too, resolving the issue, but if your DMZ was ever penetrated, someone could potentially use DNS to help map out your network. Otherwise, you'd want to add a DNS server in your DMZ or use HLB just for this which I wouldn't
be in love with.
