Is it possible to run a server cluster with Mavericks?

Is it possible to run a server cluster, like using XGrid, but with Mavericks? I have a Mac Mini server and an older iMac lying around that I want to put to good use. If so, what software would I need and how should I set it up? Will I be able to link the 2 computers over Wifi or must it be Ethernet?

Sadly Apple no longer provide Xgrid for clustering it was last available with Lion aka. 10.7.x.
For any equivalent clustering capability you are either going to have to use an open-source Linux originated clustering solution like Slurm, Moab, or Beowulf. Then you have to applications written to be compatible with such solutions. This was the beauty of Xgrid in that it provided a framework that Mac applications could be compatible with.
Note: Clustering is not the same thing as a Storage Area Network. It is still possible to build a SAN using Macs even in Mavericks and Apple still support Xsan for this.
With regards to using WiFi or Ethernet, both would work but it will depend on how much data needs to be transferred (per second) as to wether WiFi would be up to the job, some tasks require lots of data to be transferred other tasks e.g. BitCoin mining do not.
Apple did come up with another framework called Grand Central Dispatch. In theory that might be extended to work in a cluster. However while GCD is now open-source I get the impression it is also abandoned by Apple See https://libdispatch.macosforge.org

Is it possible to run a Windows domain with a Mac Server?

Looking for some advice on getting rid of our Windows domain controller (DHCP server, AD, etc.) in favour of a Mac Server (which we own). Is it possible to run a Windows domain with a Mac Server?

Snow Leopard Server (10.6) and earlier included Samba which supported acting as an NT Domain Controller (this pre-dates Active Directory). Lion (10.7) and later as standard can no longer act as an NT Domain Controller nor can they act as an Active Directory server.
So the short answer is no.
Theoretically you could port Samba4 to a Mac and Samba4 can act as an Active Directory server. In reality this is not going to be easy but is theoretically possible.
An easier option might be to run a copy of Linux (e.g. Ubuntu) in a virtual machine e.g. using VirtualBox and then run Samba4 in that and configure it to act as and Active Directory server. Then you could connect the Mac side to the Samba4 Active Directory server. This approach would use all Mac hardware, and not have any extra costs of licenses to buy and as far as all the rest of the network is concerned would be a standard Active Directory server environment.

Is it possible to run an IdocScript Query with Service GET_SEARCH_RESULTS?

Hi All,
I need to run the below query with GET_SEARCH_RESULTS service.
dDocType <matches> `ArchivePackage` <AND> xSubmissionDate < `10/08/13 11:03 AM` <AND> xArchiveDocName <EQUALS> dDocName
Part of this query works fine but when the part in BOLD is also used I get an error, reason being there is nothing like <EQUALS> when using QueryBuilder
Instead is it possible to run the below idocscript with any service?
<$ (dDocType like 'ArchivePackage') & xSubmissionDate < dateCurrent(-365) & (XArchiveDocname == dDocname) $>
I tried it with GET_SEARCH_RESULTS, but got wrong results and no error.
Is this even possible or should I just change my approach?
Regards

I tried to search more info on this one. It is true that in all cases the operator is followed by a constant - see e.g. https://blogs.oracle.com/interactions/entry/ucm_get_search_results_with_full_text_search
Honestly, I see no reason why a reference to another metadata could not be made, but the parser might just fail on it. If you can, try to get an official answer from support via Metalink. Alternatively, you can decompile the code processing the service and check why parsing fails when non-constants are used.

I wonder if the disk being referred to is actually your iPod which is not plugged in. Maybe something has stuck thinking the iPod should be there.
Try completely removing all the iTunes related programs according to this method.

Restart you PC and see if startup improves.
If it doesn't improve you need to consider the possibility that there is something else going on.
If The problem goes away, hopefully a fresh install will be OK.

Will 2 routers running in server mode with no vtp domain defined conflict with each other when connecting over layer 2 sonet?

Our remote site has a 3845 router running MPLS to connect back to our other 3845 locally. The ISP has provided us a layer 2 sonet connection with no other configurations necessary with the exception of configuring the layer 2 portion on our side. Both of these 3845 routers are in "server mode" with "no vtp domain" specified. Will this cause an issue/conflict when the remote router bypasses the MPLS for the faster 100MB layer 2 connection?

Jon,
Excellent answer. Our two 3845 routers are about 400 miles away and we're trying to bring up a layer 2 100MB sonet connection over fiber connected to the GIG0/1 port on each router. I was worried that essentially having these 2 routers back to back over layer 2 may cause issues since our remote site has a higher revision number than our local site. It appears since we're configuring an ip address on each router and then adding the network to ospf this shouldn't conflict with our 2 routers. Below is how each router VTP is configured with the exception our remote site has 1 extra VLAN and a higher revision number.
VTP Version                     : 2
Configuration Revision          : 0
Maximum VLANs supported locally : 68
Number of existing VLANs        : 5
VTP Operating Mode              : Server
VTP Domain Name                 :
VTP Pruning Mode                : Disabled
VTP V2 Mode                     : Disabled
VTP Traps Generation            : Enabled
MD5 digest                      : 0xBF 0x86 0x94 0x45 0xFC 0xDF 0xB5 0x70

Is it possible to Run VM Server and VM Manager on a single machine

Hi,
I'm trying to learn VM and I downloaded both the VM Server and Manager from E-Delivery. The guide says I need two separate machines for the VM server and VM manager.
Does this mean I've to install the VM Server first and then Install VM Manager on a different machine, create the Virtual Machines and then run the Virtual Machines on the VM Server?
If I've got only one laptop, does that mean I've to install the Enterprise Linux first, install the VM Manager, create all the VM Machines I'll need from the Installation sources, then install the VM Server on the machine a fresh and run the created VM Machines on it?
I'm relatively new to Virtualization and any help would be highly appreciated.

There are other messages about running OVMM in the first VM on an OVM Server.
Yes, Oracle supports them both being on the same physical system. They even supply a template for it.
I tried to install it yesterday, but hit a resource snag. The testbed system I have available only has 2GB of memory and the OVMM template installation script aborts if the OVM Server does not have more than 2GB of memory. So my experiments for a faster DR process will have to wait for better hardware.

newbie Possibility to run X Server and Tiger both

Hi there I have a question about the following:
I want to install Oracle on my iBook G4 but unfortunaltely there seems only a possibilty for this by installing X server. Currently I have tiger and it is working just fine I do not need to have x server as main operating system because tiger is sufficient to me. My question is if there is any possibility that you can install X server and tiger both and choose which one to use when starting up. If so how do I have to do this and is it wise to do it or not?
If it it not possible does anyone know if there is a possibility to install Oracle on my G4? I have a wireless home network with only one Mac (iBook G4) and that’s it .
Well thank you in advance.
Scotia

It all depends on the size of your data on the Mac os X client setup .. tiger server can sure cohabit with mac os x client ... but first you will need to backup everything on an external drive using Carbon Copy Cloner boot off your external hard drive , split your partition on the internal hard drive then back your macos x client down to your hard drive then install mac os x server on the secondary partition of your internal hard drive ...
Hoping this helps
PS: you can install mac os x server over a mac os X client installation but make SURE you backup your original installation and are ready to face a few updates. If possible try to get your hands on a copy of mac os x server 10.4.8 Universal.

Monitoring printers attched to a Windows print server cluster with Operations Manager

Is it possible to run a deskjet 350cbi with win7?

hi, i am trying to use my old portable deskjet 350 cbi with my laptop the os is win7 and via a IR connection, is their a driver available or is their a work around any advice please.

The only Windows 7 driver for the 350cbi is built into Windows 7. It is listed as USB connectivity only. If you can get Windows 7 to recognize the printer as an IR device, it may be possible. This document may offer some help as far as the IrDA setup is concerned:

Regarding shared file system requirement in endeca server cluster

Hi,
Our solution involves running a single data domain in an endeca server cluster.
As per the documentation, endeca server cluster requires shared file system for keeping index file for follower node to read.
My questions are,
Can I run the endeca cluster with out shared file system by having the index file on each node of the endeca server cluster?
Can dependency on shared file system be a single point of failure, if yes how can it be avoided?
I really appreciate your feedback on these questions.
thanks,
rp

Hi rp,
The requirement for a shared file system in the Endeca Server cluster is a must. As this diagram shows, the shared file system maintans the index, and also maintains the state of the Cluster Coordinator, which ensures cluster services (automatic leader election, propagation of the latest index version to all nodes in the data domain). A dependency on a shared file system can be a single point of failure and requires to run a backup, -- this is a standard IT approach, that is, it is not specific to the Endeca Server cluster in particular.
See this section on Cluster Behavior, for info on how the shared file system is used (the topic "how updates are processed"), and on how increased availability is achieved.

Running Weblogic Server 7.0 SP4 using JDK 1.4

Is it possible to run Weblogic Server 7.0 SP4 with a different JRE than the one
that ships with 7.0 SP4. I am having issues with a bug in JDK 1.3.1 which when
I run under JBuilder X using 1.4 is not there. ANy help as to how I go about
doing this would be welcomed.
Thanks
Justin

Yes,
The JDK is just the Sun JDK...nothing special. You may upgrade minor versions quite safely by dowloading later one at Sun website and pointting your "JAVA_HOME" at it.
I would not jump to 1.4, as changes in java language may impact.

Exchange Server 2013 and Remote Access VPN on a single server running Windows Server 2012?

Just by way of background, I have been installing and administering network servers, e-mail systems, VPN servers, and the like for many years. However, my involvement with Exchange and Windows Server has been mostly on the forensics and data recovery
level, or as a (sophisticated) user. I have never tried to deploy either from scratch before. My deployment experiences have been mostly with Linux in recent years, and with small private or personal "servers" running such cutting edge
software as Windows XP back when it was new. And even NetWare once.
When a client asked me if I could set up a server for his business, running Exchange Server (since they really want Outlook with all of its bells and whistles to work, particularly calendars) and providing VPN access for a shared file store, I figured it
could not be too difficult given that its a small business, with only a few users, and nothing sophisticated in the way of requirements. For reasons that don't bear explaining here, he was not willing to use a vendor hosting Exchange services or cloud
storage. There is no internal network behind the server; it is intended to be a stand-alone server, hanging off a static IP address on the Internet, providing the entirely mobile work-force of about 10 people with Exchange-hosted e-mail for their computers
and phones, a secure file store, and not much else. If Exchange didn't need it, I would not need to install Active Directory, for example. We have no direct need for its services.
So I did the research and it appears, more by implication than outright assertion, that I should be able to run Windows Server 2012 with Exchange Server 2013 on a server that also hosts Remote Access (VPN only) and does nothing else. And it appears
I ought to be able to do it without virtualizing any of it. However, I have spent the last three or four days fighting one mysterious issue after another. I had Remote Access VPN working and fairly stable very quickly (although it takes a very
long time to become available after the server boots), and it has mostly remained reliable throughout although at times while installing Exchange it seems to have dropped out on me. But I've always been able to get it back after scrounging through the
logs to find out what is bothering it. I have occasionally, for a few minutes at a time, had Exchange Server willing to do everything it should do (although not always everything at the same time). At one point I even received a number of e-mails
on my BlackBerry that had been sent to my test account on the Exchange Server, and was able to send an e-mail from my BlackBerry to an outside account.
But then Exchange Server just stopped. There are messages stuck in the queues, among other issues, but the Exchange Administration Center refuses now to display anything (after I enter my Administrator password, I just get a blank screen, whether on
the server or remotely).
So, I am trying to avoid bothering all of you any more than I have to, but let me just begin with the basic question posed in the title: Can I run Exchange Server (and therefore Active Directory and all of its components) and Remote Access (VPN only) on
a single Windows Server 2012 server? And if so, do I have to run virtual machines (which will require adding more memory to the server, since I did not plan for it when I purchased it)? If it can be done, can anyone provide any pointers on what
the pitfalls are that may be causing my problems? I am happy to provide whatever additional information anyone might like to help figure it out.
Thanks!

An old thread but I ran into this issue and thought I share my solution since I ran into the same issue. Configuring VPN removes the HTTPS 443 binding on the Default Site in IIS for some strange reason; just go and editing the bindings, add HTTPS and things
should be back to normal.

Listener service not start automatically after reboot in Win2K server Clust

Hi all,
I set up a two node Server Cluster with Microsoft Windows 2000 server cluster service. Hardware are two HP DL380 servers and HP MSA500 (the shared storage). The cluster's IP address is 10.1.241.65. When I shut down both servers and restart the primary server, the listener server service will not start automatically. The listener log is:
Started with pid=1108
Error listening on: (DESCRIPTION=(ADDRESS=(PROTOCOL=TCP)(HOST=10.1.241.65)(PORT=1521)))
TNS-12545: Connect failed because target host or object does not exist
TNS-12560: TNS:protocol adapter error
TNS-00515: Connect failed because target host or object does not exist
32-bit Windows Error: 49: Unknown error
The service is set up automatically start. I suspect the cluster virtual IP is not available immediately after reboot. So I tried setting the Recovery after first failure and second failure to 3 minitues each, and setting up Dependencies of the listener on the cluster service in the Win2K Service panel. Neither worked.
The service can be manually start.
Any suggestion?
Frank.

The command to start automatically the listener is :
lsnrctl start
check the parameters in : <ORACLE_HOME>/network/admin/listener.ora
check the IP address or host name

Windows Server 2012 R2 Scale out file server cluster using server disks as CSV

Hi,
My question is if I can create a Scale Out File Server Cluster with CSV using the disks that comes with the servers, we have 2 servers with 2 arrays each one, 1 array for the OS files and 1 array that we could use for the CSV.
Regards.

Hi,
a SoFS needs some kind of shared Storage, this could be in the old days ISCSI or FC SAN and now also a Shared SAS JBOD with Clustered Storage Spaces.
If you have 2 Servers with "local" Disks you need some sort of Software to create a Shared Disk Layer out of that local Disks, like Starwind or DataCore.

Udo
Udo, clustered RAID controllers still require SAS disks mounted into external enclosure *OR* everything mounted into single chassis for Cluster-In-A-Box scenario (but that's for OEMs). The only two benefits somebody would have with them are a) ability to
privide RAID LUs to Clustered Storage Spaces (non-clustered RAID controllers would be used as a SAS controllers only in pass-thru mode) and b) abillity to have caches synchronized so VM moved from one physical host to another would not start from the "cold"
state. Please see LSI Syncro reference manual for details:
