Recommendations for Multipathing software in Sun Cluster 3.2 + Solaris 10
Hi all, I'm in the process of building a 2-node cluster with the following specs:
2 x X4600
Solaris 10 x86
Sun Cluster 3.2
Shared storage provided by a EMC CX380 SAN
My question is this: what multipathing software should I use? The in-built Solaris 10 multipathing software or EMC's powerpath?
Thanks in advance,
Stewart
Hi,
according to http://www.sun.com/software/cluster/osp/emc_clarion_interop.xml you can use both.
So at the end it all boils down to
- cost: Solaris multipathing is free, as it is bundled
- support: Sun can offer better support for the Sun software
You can try to browse this forum to see what others have experienced with Powerpath. From a pure "use as much integrated software as possible" I would go with the Solaris drivers.

I just purchased MBP and it is my first Apple computer. How concerned should I be about virus software and what do you recommend for security software?
1. This comment applies to malicious software ("malware") that's installed unwittingly by the victim of a network attack. It does not apply to software, such as keystroke loggers, that may be installed deliberately by an intruder who has hands-on access to the victim's computer. That threat is in a different category, and there's no easy way to defend against it. If you have reason to suspect that you're the target of such an attack, you need expert help.
2. All versions of OS X since 10.6.7 have been able to detect known Mac malware in downloaded files, and to block insecure web plugins. This feature is transparent to the user, but internally Apple calls it "XProtect." The malware recognition database is automatically checked for updates once a day; however, you shouldn't rely on it, because the attackers are always at least a day ahead of the defenders.
The following caveats apply to XProtect:
It can be bypassed by some third-party networking software, such as BitTorrent clients and Java applets (see below.)
It only applies to software downloaded from the network. Software installed from a CD or other media is not checked.
3. Starting with OS X 10.7.5, there has been another layer of built-in malware protection, designated "Gatekeeper" by Apple. By default, applications and Installer packages downloaded from the network will only run if they're digitally signed by a developer with a certificate issued by Apple. Software certified in this way hasn't actually been tested by Apple (unless it comes from the Mac App Store), but you can be reasonably sure that it hasn't been modified by anyone other than the developer. His identity is known to Apple, so he could be held legally responsible if he distributed malware. For most practical purposes, applications recognized by Gatekeeper as signed can be considered safe.
Gatekeeper has, however, the same limitations as XProtect, and in addition the following:
It can easily be disabled or overridden by the user.
A malware attacker could get control of a code-signing certificate under false pretenses, or could find some other way to evade Apple's controls.
For more information about Gatekeeper, see this Apple Support article.
4. Beyond XProtect and Gatekeeper, there’s no benefit, in most cases, from any other automated protection against malware. The first and best line of defense is always your own intelligence. All known malware circulating on the Internet that affects a fully-updated installation of OS X 10.6 or later takes the form of so-called "trojan horses," which can only have an effect if the victim is duped into running them. The threat therefore amounts to a battle of wits between you and the malware attacker. If you're smarter than he thinks you are, you'll win.
That means, in practice, that you never use software that comes from an untrustworthy source. How do you know whether a source is trustworthy?
Any website that prompts you to install a “codec,” “plug-in,” "player," "extractor," or “certificate” that comes from that same site, or an unknown one, is untrustworthy.
A web operator who tells you that you have a “virus,” or that anything else is wrong with your computer, or that you have won a prize in a contest you never entered, is trying to commit a crime with you as the victim. (Some reputable websites did legitimately warn visitors who were infected with the "DNSChanger" malware. That exception to this rule no longer applies.)
Pirated copies or "cracks" of commercial software, no matter where they come from, are unsafe.
Software of any kind downloaded from a BitTorrent or from a Usenet binary newsgroup is unsafe.
Software with a corporate brand, such as Adobe Flash Player, must be downloaded directly from the developer’s website. If it comes from any other source, it's unsafe.
5. Java on the Web (not to be confused with JavaScript, to which it's not related, despite the similarity of the names) is a weak point in the security of any system. Java is, among other things, a platform for running complex applications in a web page, on the client. That was never a good idea, and Java's developers have had a lot of trouble implementing it without also creating a portal for malware to enter. Past Java exploits are the closest thing there has ever been to a Windows-style "virus" affecting OS X. Merely loading a page with malicious Java content could be harmful. Fortunately, Java on the Web is mostly extinct. Only a few outmoded sites still use it. Try to hasten the process of extinction by avoiding those sites, if you have a choice.
Java is not included in OS X 10.7 and later. Discrete Java installers are distributed by Apple and by Oracle (the developer of Java.) Don't use either one unless you need it. Most people don't. If Java is installed, disable it — not JavaScript — in your browsers. In Safari, this is done by unchecking the box marked Enable Java in the Security tab of the preferences dialog.
Regardless of version, experience has shown that Java on the Web can't be trusted. If you must use a Java applet for a specific task, enable Java only when needed for the task and disable it immediately when done. Close all other browser windows and tabs, and don't visit any other sites while Java is active. Never enable Java on a public web page that carries third-party advertising. Use it only on well-known, password-protected, secure websites without ads. In Safari 6 or later, you'll see a lock icon in the address bar with the abbreviation "https" when visiting a secure site.
Follow these guidelines, and you’ll be practically as safe from malware as you can be.
6. Never install any commercial "anti-virus" or "Internet security" products for the Mac, as they all do more harm than good, if they do any good at all. If you need to be able to detect Windows malware in your files, use the free software ClamXav — nothing else.
Why shouldn't you use commercial "anti-virus" products?
Their design is predicated on the nonexistent threat that malware may be injected at any time, anywhere in the file system. Malware is downloaded from the network; it doesn't materialize from nowhere.
In order to meet that nonexistent threat, the software modifies or duplicates low-level functions of the operating system, which is a waste of resources and a common cause of instability, bugs, and poor performance.
By modifying the operating system, the software itself may create weaknesses that could be exploited by malware attackers.
7. ClamXav doesn't have these drawbacks. That doesn't mean it's entirely safe. It may report email messages that have "phishing" links in the body, or Windows malware in attachments, as infected files, and offer to delete or move them. Doing so will corrupt the Mail database. The messages should be deleted from within the Mail application.
ClamXav is not needed, and should not be relied upon, for protection against OS X malware. It's useful only for detecting Windows malware. Windows malware can't harm you directly (unless, of course, you use Windows.) Just don't pass it on to anyone else.
A Windows malware attachment in email is usually easy to recognize. The file name will often be targeted at people who aren't very bright; for example:
♥♥♥♥♥♥♥♥♥♥♥♥♥♥!!!!!!!H0TBABEZ4U!!!!!!!.AVI♥♥♥♥♥♥♥♥♥♥♥♥♥♥.exe
ClamXav may be able to tell you which particular virus or trojan it is, but do you care? In practice, there's seldom a reason to use ClamXav unless a network administrator requires you to run an anti-virus application.
8. The greatest harm done by anti-virus software, in my opinion, is in its effect on human behavior. It does little or nothing to protect people from emerging threats, but they get a false sense of security from it, and then they may behave in ways that expose them to higher risk. Nothing can lessen the need for safe computing practices.
9. It seems to be a common belief that the built-in Application Firewall acts as a barrier to infection, or prevents malware from functioning. It does neither. It blocks inbound connections to certain network services you're running, such as file sharing. It's disabled by default and you should leave it that way if you're behind a router on a private home or office network. Activate it only when you're on an untrusted network, for instance a public Wi-Fi hotspot, where you don't want to provide services. Disable any services you don't use in the Sharing preference pane. All are disabled by default. -
SAP 7.0 on SUN Cluster 3.2 (Solaris 10 / SPARC)
Dear All;
i'm installing a two nodes cluster (SUN Cluster 3.2 / Solaris 10 / SPARC), for a HA SAP 7.0 / Oracle 10g DataBase
SAP and Oracle softwares were successfully installed and i could successfully cluster the Oracle DB and it is tested and working fine.
for the SAP i did the following configurations
# clresource create -g sap-ci-res-grp -t SUNW.sap_ci_v2 -p SAPSID=PRD -p Ci_instance_id=01 -p Ci_services_string=SCS -p Ci_startup_script=startsap_01 -p Ci_shutdown_script=stopsap_01 -p resource_dependencies=sap-hastp-rs,ora-db-res sap-ci-scs-res

and when trying to bring the sap-ci-res-grp online # clresourcegroup online -M sap-ci-res-grp
it executes the startsap scripts successfully as following

can anyone one help me if there is any error on configurations or what is the cause of this problem.....thanks in advance
ARSSESHi all.
I am having a similar issue with a Sun Cluster 3.2 and SAP 7.0
Scenrio:
Central Instance (not incluster) : Started on one node
Dialog Instance (not in cluster): Started on the other node
When I create the resource for SUNW.sap_as like
clrs create --g sap-rg -t SUNW.sap_as .....etc etc
in the /var/adm/messages I got lots of WAITING FOR DISPACHER TO COME UP....
Then after timeout it gives up.
Any clue? What does is try to connect or waiting for? I hve notest that it's something before the startup script....

Veritas required for Oracle RAC on Sun Cluster v3?
Hi,
We are planning a 2 node Oracle 9i RAC cluster on Sun Cluster 3.
Can you please explain these 2 questions?
1)
If we have a hardware disk array RAID controller with LUNs etc, then why do we need to have Veritas Volume Manager (VxVM) if all the LUNS are configured at a hardware level?
2)
Do we need to have VxFS? All our Oracle database files will be on raw partitions.
Thanks,
Steve> We are planning a 2 node Oracle 9i RAC cluster on Sun
Cluster 3.Good. This is a popular configuration.
Can you please explain these 2 questions?
1)
If we have a hardware disk array RAID controller with
LUNs etc, then why do we need to have Veritas Volume
Manager (VxVM) if all the LUNS are configured at a
hardware level?VxVM is not required to run RAC. VxVM has an option (separately
licensable) which is specifically designed for OPS/RAC. But if
you have a highly reliable, multi-pathed, hardware RAID platform,
you are not required to have VxVM.
2)
Do we need to have VxFS? All our Oracle database
files will be on raw partitions.No.
IMHO, simplify is a good philosophy. Adding more software
and layers into a highly available design will tend to reduce
the availability. So, if you are going for maximum availabiliity,
you will want to avoid over-complicating the design. KISS.
In the case of RAC, or Oracle in general, many people do use
raw and Oracle has the ability to manage data in raw devices
pretty well. Oracle 10g further improves along these lines.
A tenet in the design of highly available systems is to keep
the data management as close to the application as possible.
Oracle, and especially 10g, are following this tenet. The only
danger here is that they could try to get too clever, and end up
following policies which are suboptimal as the underlying
technologies change. But even in this case, the policy is
coming from the application rather than the supporting platform.

What are typical failover times for application X on Sun Cluster
Our company does not yet have any hands-on experience with clustering anything on Solaris, although we do with Veritas and Miscrosoft. My experience with MS is that it is as close to seemless (instantaneous) as possible. The Veritas clustering takes a little bit longer to activate the standby's. A new application we are bringing in house soon runs on Sun cluster (it is some BEA Tuxedo/WebLogic/Oracle monster). They claim the time it takes to flip from the active node to the standby node is ~30minutes. This to us seems a bit insane since they are calling this "HA". Is this type of failover time typical in Sun land? Thanks for any numbers or reference.
This is a hard question to answer because it depends on the cluster agent/application.
On one hand you may have a simple Sun Cluster application that fails over in seconds because it has to do a limited amount of work (umount here, mount there, plumb network interface, etc) to actually failover.
On the other hand these operations may, depending on the application, take longer than another application due to the very nature of that application.
An Apache web server failover may take 10-15 seconds but an Oracle failover may take longer. There are many variables that control what happens from the time that a node failure is detected to the time that an application appears on another cluster node.
If the failover time is 30 minutes I would ask your vendor why that is exactly.
Not in a confrontational way but a 'I don't get how this is high availability' since the assumption is that up to 30 minutes could elapse from the time that your application goes down to it coming back on another node.
A better solution might be a different application vendor (I know, I know) or a scalable application that can run on more than one cluster node at a time.
The logic with the scalable approach is that if a failover takes 30 minutes or so to complete it (failover) becomes an expensive operation so I would rather that my application can use multiple nodes at once rather than eat a 30 minute failover if one node dies in a two node cluster:
serverA > 30 minute failover > serverB
seems to be less desirable than
serverA, serverB, serverC, etc concurrently providing access to the application so that failover only happens when we get down to a handful of nodes
Either one is probably more desirable than having an application outage(?) -
Bizzare Disk reservation probelm with sun cluster 3.2 - solaris 10 X 4600
We have a 4 node X4600 sun cluster with shared AMS500 storage. There over 30 LUN's presented to the cluster.
When any of the two higher nodes ( ie node id 2 and node is 3 ) are booted, their keys are not added to 4 out of 30 LUNS. These 4 LUNs show up as drive type unknown in format. I've noticed that the only thing common with these LUN's is that their size is bigger than 1TB
To resolve this I simply scrub the keys, run sgdevs than they showup as normal in format and all nodes keys are present on the LUNS.
Has anybody come across this behaviour.
Commands used to resolve problem
1. check keys #/usr/cluster/lib/sc/scsi -c inkeys -d devicename
2. scrub keys #/usr/cluster/lib/sc/scsi -c scrub -d devicename
3. #sgdevs
4. check keys #/usr/cluster/lib/sc/scsi -c inkeys -d devicename
all node's keys are now present on the lunHi,
according to http://www.sun.com/software/cluster/osp/emc_clarion_interop.xml you can use both.
So at the end it all boils down to
- cost: Solaris multipathing is free, as it is bundled
- support: Sun can offer better support for the Sun software
You can try to browse this forum to see what others have experienced with Powerpath. From a pure "use as much integrated software as possible" I would go with the Solaris drivers.

Sun Cluster 3.2/Solaris 10 Excessive ICMP traffic
Hi all,
I have inherited a 2 node cluster with a 3510 san which I have upgraded to Cluster 3.2/Solaris 10. Apparently this was happening on Cluster 3.0/Solaris 8 as well.
The real interfaces on the two nodes seem to be sending excessive pings to the default gateway it is connected to. The configuration of the network adapters are the same - 2 NIC's on each are grouped for multi-home and 2 NIC's configured as private for cluster heartbeats.
The 2 NIC's that are grouped together on each of the servers are the cards generating the traffic.

Any suggestions on why the excessive traffic?I would guess these are the ipmp probes (man in.mpathd).
You can start in.mpathd in debug mode to find out.

Any recommendations for editing software
Can anyone recommend a good editing software, Uk or Australian English, for use with a 200 page document in Pages?
Pages supposedly has an Australian dictionary but it is just the British dictionary.
Not sure what you are asking for as Pages generally does not allow plug-ins other then EndNotes.
There are plenty of alternative text editors out there, depends what you need.
Is this an academic submission? Do you need line numbers/ Any other special requirements?
Or are you simply asking how to use the Australian Dictionary to spellcheck?

Recommendations for banking software...Quicken?
I'm a new Mac user. I use quicken on my windows machine, does anyone recommend banking software for the Mac? I have read some reviews about quicken for mac and users rated the software poorly.
I just read in the latest MacWorld that you can run Quicken for Windows in its own containor (no need to get Windows Operating System) with the help of CodeWeavers' $40 CrossOver Impersonator. It's a product that enables your Mac to run certain Windows applications like Quicken.
The CodeWeavers website <www.codeweavers.com> says their product will run Quicken 2011 Deluxe, but that the Quicken 2011 Premier version (needed for investment tracking) is currently untested. -
Recommendations for Encryption Software
I am planning on going paperless with employee documents. For me to keep this on my computer I need a program which can safely protect this data and keep it private. I want to setup a standard hierarchy with a "Employee Folder" folder, and a folder inside that folder for each employee. I want this stuff password protected and encrypted so no one can easily get into it. Any suggestions on software that can allow me to create encrypted folders easily, put folders inside folders, and easily put documents inside those folders?
Quite a mouthful huh?I don't know about third-party software (which you must hope continues to be supported), but you can create encrypted disk images in the OS:
http://support.apple.com/kb/HT1578
When chooseing the image format, I would suggest Sparse Bundle Disk Image as that can be efficiently backed up by Time Machine.
Take note of step 10. You probably do not want to store the password in the keychain.
A disk Image mounts just like a hard drive. When you eject it, the file is encrypted again. -
Recommendations for blogging software
I want to start a few blogs. I was thinking about using WordPress with a full range of the features(not the free one).
BlueHost is the most popular host for WP, but turns out it doesn't support Mac.
Are there other webhosts that do support Mac ?
What are the alternatives for blogging, both free and not free ?Is it worth it? Good question. If you use iWeb for blogging and want comments integrated .Mac is the easiest solution. At the end, you need to decide, if you want that kind of money, if cheaper options are available. .Mac is nice and fancy, but also has some restrictions.
Wordpress on the other hand is for free, installation on a server very easy or even preinstalled. Wordpress is the tool of choice for a lot of professional bloggers and it has a great reputation. If you are serious about blogging, this might be a very good option, or going with Rapidweaver as you can also blog to a 3rd part webserver.
I run my main [blog|http://blog.jurgen-photo.com] currently on Wordpress and experiment with iWeb on my [customer website|http://www.jurgen-photo.com]. -
Any recommendations for encryption software for iPhone?
Hi,
I want to store some work data on my new iPhone. A mixture of file types - documents, pictures, Powerpoint, applications.
I also want to keep some of my home information - such as documents, pictures, apps.
Where can I put them on the iPhone, and can I encrypt them in a few folders to keep the data secure?
Thanks
PeteActually there are a few apps that do just that. I personally use MobileFinder, but there is also datacase and others I can't remember.
However these are not password protected they simply allow you to transfer documents onto the iphone and view them. MobileFinder has limited text editing facilities.
Theres an application called PicVault which allows the encrypted storage of pictures, using a password. -
SUN Cluster 3.2, Solaris 10, Corrupted IPMP group on one node.
Hello folks,
I recently made a network change on nodename2 to add some resilience to IPMP (adding a second interface but still using a single IP address).
After a reboot, I cannot keep this host from rebooting. For the one minute that it stays up, I do get the following result from scstat that seems to suggest a problem with the IPMP configuration. I rolled back my IPMP change, but it still doesn't seem to register the IPMP group in scstat.

I believe that I should be able to delete the IPMP group for the second node from the cluster and re-add it, but I'm sure about how to go about doing this. I welcome your comments or thoughts on what I can try before rebuilding this node from scratch.
-AGI was able to restart both sides of the cluster. Now both sides are online, but neither side can access the shared disk.
Lots of warnings. I will keep poking....

Failover Zones / Containers with Sun Cluster Geographic Edition and AVS
Hi everyone,
Is the following solution supported/certified by Oracle/Sun? I did find some docs saying it is but cannot find concrete technical information yet...
* Two sites with a 2-node cluster in each site
* 2x Failover containers/zones that are part of the two protection groups (1x group for SAP, other group for 3rd party application)
* Sun Cluster 3.2 and Geographic Edition 3.2 with Availability Suite for SYNC/ASYNC replication over TCP/IP between the two sites
The Zones and their application need to be able to failover between the two sites.
Thanks!
Wim OlivierFritz,
Obviously, my colleagues and I, in the Geo Cluster group build and test Geo clusters all the time :-)
We have certainly built and tested Oracle (non-RAC) configurations on AVS. One issue you do have, unfortunately, is that of zones plus AVS (see my Blueprint for more details http://wikis.sun.com/display/BluePrints/Using+Solaris+Cluster+and+Sun+Cluster+Geographic+Edition). Consequently, you can't built the configuration you described. The alternative is to sacrifice zones for now and wait for the fixes to RG affinities (no idea on the schedule for this feature) or find another way to do this - probably hand crafted.
If you follow the OHAC pages (http://www.opensolaris.org/os/community/ha-clusters/) and look at the endorsed projects you'll see that there is a Script Based Plug-in on the way (for OHACGE) that I'm writing. So, if you are interested in playing with OHACGE source or the SCXGE binaries, you might see that appear at some point. Of course, these aren't supported solutions though.
Regards,
Tim

Sun cluster, 6140 and 'cross-connections'
This was brought up in the storage forum by somebody else, but the responses never answered the original question:
In the 6140 setup document located at http://docs.sun.com/source/819-7497-11/chapter3.html#50589714_93886 it shows two different ways to cable a host to a 6140 via a SAN switch. figure 3-3 and 3-4
It states that the setup in 3-4 is not supported in a sun cluster environment.
The problem is that given the acive/passive nature of the 6140, the setup shown in 3-4 is the obvious one to use since it prevents one from having to force all of the luns over in the event of an hba port or switch failure.
To make life more interesting, the 6140 setup doc does not make not of what version of sun cluster it is not supported on. Or what the bugid is, or any informationto know if the restriction is still valid.
So, does this restriction still exist? If so, for what version of sun cluster? What version of solaris?Thanks for the clarification.
As an aside, it would be nice if in the future, the documentation could contain a bit more information than just a simple note saying 'this is not supported'. A reference to a bugid or info doc would go a long way in helping folks determine if the restriction is still valid.
