In my closing tip, I compiled an inventory of the appropriate 50 Unix instructions. every of the instructions I discussed are available on...
the properly three Unix editions: Solaris, AIX and HP-UX. listed here, i may stroll you during the historical past of those Unix flavors, talk about some their simple differences and close with a command table evaluation of crucial projects.
sun SolarisSolaris, sun's Unix version, turned into basically the successor of SunOS, going again to1992. SunOS become at the start in keeping with the BSD flavor of Unix, whereas SunOS types 5.0 and later are in line with Unix device V unencumber four (rebranded as Solaris).
How did this occur? Let's go additional returned in time. SunOS version 1.0 become brought in 1983 with help for sun-1 and sun-2 programs. edition 2.0 become brought in 1985 -- its declare to repute turned into digital file system (VFS) and NFS. In 1987, AT&T and sun introduced that they would work together on a project to merge system V and BSD into one unlock, in keeping with SVR4. Solaris 2.4 become solar's first Sparc/x86 liberate. The final free up of SunOS changed into edition 4.1.4 in November 1994. Solaris 7 was its first 64-bit extremely Sparc unencumber and brought native guide for file system metadata logging. Solaris 9, added in 2002, introduced assist for Solaris extent supervisor and Linux capabilities. Solaris 10 was first brought in 2005, which has a number of improvements, including guide for its new ZFS file equipment, Solaris Containers and Logical Domains.
Solaris is at the moment as much as version 10; the newest update was launched in October 2008. amongst its innovations is help for paravirtualization, where Solaris 10 is used as a guest in Xen-primarily based environments.
primary modifications and interesting characteristics. Solaris is free and open supply, disbursed in the course of the OpenSolaris operating device. Solaris is a extra command-line primarily based Unix working equipment than HP-UX or AIX. As a realistic count, it does not have anything else similar to equipment Administration manager (SAM) on HP-UX or system administration Interface tool (SMIT) on AIX. Solaris runs on Sparc and x86 environments. It additionally has the newest file system round -- ZFS, which has made incredible strides in recent years, including the means to now use it as its root file equipment. ZFS has the talents to be the surest all-round Unix file device. Solaris has many ways to put in force virtualization, together with Containers/zones, xVM Server, Logical Domains and hardware partitioning.
Hewlett-Packard HP-UXHP-UX, Hewlett-Packard's Unix, turned into at the start in line with equipment V unencumber three. It firstly ran solely on PA-RISC HP 9000 platform. version 1 of HP-UX was launched in 1984. edition 9, delivered its character-based graphical user interface (GUI), SAM, from which one administrates the system. edition 10, added in 1995, introduced adjustments in the layout of the device file and listing constitution, making it akin to AT&T SVR4. edition 11 become added in 1997 and turned into HP's first free up to assist 64-bit addressing. In 2000, it changed into rebranded to 11i, when HP added working environments, bundled organizations of layered functions for particular IT functions. In 2001, edition eleven.20 delivered support for Itanium systems. HP-UX turned into the first Unix that used access manage Lists (ACLs) for file permissions and was additionally one of the most first to introduce constructed-in aid for Logical volume supervisor. today, HP-UX uses Veritas as its simple file system as a result of the close partnership between Veritas and HP. HP-UX is at present up to unencumber 11iv3, replace four.
simple transformations and pleasing features. HP-UX is the primary of the Unix systems to enable its shoppers to buy certain working environments. for instance, in case you are trying to find its high availability (HA) product Serviceguard, you possibly can buy the particular product that bundles in HA. HP-UX is the best version that uses a third-birthday celebration file device -- Veritas (sun used to offer this decades ago). HP has many types of virtualization, together with nPartitions, vPars, Integrity digital Machines (IVMs) and aid partitions. This does have a bent to confuse some folks as a result of there are such a lot of selections. HP-UX runs on both HP 9000s and Integrity Itanium methods. HP-UX 11v3 can support as much as 128 processor cores. HP-UX offers for a extremely effective command line moreover its menu bases equipment, SAM. performance tuning the use of kctune is in many ways more convenient to what AIX and Solaris present.
IBM AIXAIX become brought by IBM in 1986. whereas it's in accordance with Unix gadget V, it additionally has BSD roots and, more than any other flavor, is a hybrid of both. AIX is the first OS to introduce a journaled file gadget (JFS). It became additionally the primary to have an built-in Logical extent supervisor (LVM). IBM first ported AIX to its RS/6000 platform in 1989. version 5L become a leap forward unlock added in 2001 that offered for Linux affinity and logical partitioning with the Power4 servers. In 2004, AIX delivered virtualization in AIX 5.three. superior vigour Virtualization (APV) provided micro-partitioning, shared processor swimming pools and Symmetric multi-threading. In 2007, IBM better its virtualization product, coinciding with the free up of AIX 6.1 and the Power6 architecture. It also rebranded APV to PowerVM. The AIX enhancements included a form of workload partitioning called WPARs, which might be similar to than Solaris zones/Containers however with better functionality. The newest unencumber is AIX 6.1.
primary adjustments and unique traits. IBM is greatly recognized as having the superior virtualization product on the midrange, PowerVM. Some contemporary innovations encompass live software mobility (enabling one to fail over working partitions with out taking downtime), energetic memory Sharing and varied shared processor swimming pools. No different flavor of Unix can boast these virtualization traits, nor can they fit IBM's 40-12 months background of virtualization -- PowerVM has advanced from mainframe/device z virtualization.
AIX runs handiest on IBM energy techniques -- with ease the strongest of midrange Unix servers. IBM sells the fact that AIX runs solely on power as a plus since it is absolutely optimized on this architecture and it has a clear road map around which the company adheres to religiously. it's going to even be referred to that you'll run both Linux and AIX partitions on this platform. Its LX86 virtualization add-on permits one to run x86 Linux purposes that are not ported to the power architecture. AIX has always had an integrated logical quantity supervisor, in contrast to other flavors that require add-on products. AIX is the most effective Unix that has persevered to develop market share in recent years, partly because of the capabilities of its vigour hardware that continues to lead the field in reliably, availability and scalability.

Microsoft’s windows working systems account for the largest share of server spending within the records center, however home windows is with the aid of no means the best display in town: Linux’s market share in particular is growing to be strongly. It’s turning out to be as a result of in purple Hat enterprise Linux (RHEL) and SUSE Linux business Server (SLES) there are at least two distros which are seen as business equipped and appropriate for the massive time, and also since it’s affordable, manageable, good for virtualization and it runs the utility that many individuals want to use. there are lots of more motives as well.
What that skill is that there is often many extra “enormously combined” facts middle environments (which means environments working a major variety of servers the use of each windows and Linux) in the future than there have been during the past. home windows-best records facilities, or ones which only run the peculiar Linux server or two, will become increasingly rare.
but how do you manage mixed environments? working different administration programs for each platform is inefficient and would force many directors nuts. anyway, the whole point of a administration gadget is to enable the monitoring and controlling of every valuable system in a company from a single console. now not from two or three.extra On blended Environments
Virtualization makes issues much more complicated: How do you manipulate windows and Linux servers which may well be running on physical servers or as virtual machines operating on Microsoft’s Hyper-V, VMware’s ESX, or the Xen hypervisor?Competing administration choices
when you are coming from a home windows atmosphere and relocating toward a mixed atmosphere through imposing Linux, then you definately may also already be the use of Microsoft’s gadget center management device. device middle’s Operations manager 2007 module now includes (in beta) a pass Platform Extensions pack with aid for:
digital machines are managed from equipment core the usage of the digital computer supervisor 2008 (VMM) module, which also supports digital machines working on VMware’s ESX server in addition to Hyper-V. And VMM additionally integrates with VMware’s VI3 utility in order that it can also be used to perform VI3 management operations. as an instance, it's viable, from within VMM, to initiate a VMotion operation which moves a running VMware digital desktop from one actual host to a further without stopping the virtual laptop. (Microsoft at the moment has no equivalent to VMotion —its quick Migration comprises stopping the virtual computer for some seconds because it is moved to a new host.)
by the use of competition Novell presents its Zenworks administration device, which contains desktop and mobile equipment administration in addition to management capabilities for the following server platforms:
each of those administration programs allow the administration of windows and each SLES and RHEL, however Microsoft appears to desire the previous over the latter. Demonstrating this, the business signed a set of agreements with Novell in November 2006 to work in opposition t superior interoperability between home windows and SLES in four areas:
The deal, which runs as a minimum except 2012, has been handled with an excellent deal of suspicion by means of many people, partly because it can readily be construed as a means for Microsoft to get a “pet” Linux distro which it may manage and use to get a more robust knowing of Linux and purchasers’ motives for desirous to use it for its own expertise. The deal includes an agreement for Microsoft to refrain from taking felony action against Novell’s customers for the use of Linux (which Microsoft claims infringes a considerable number of of its patents,) and additionally comprises Microsoft making funds to Novell (and hence in some way subsidizing SLES.) a method here's completed is by using buying guide coupons from Novell, which Microsoft then sells on to its consumers at a discount.
one of the crucial extremely good outcomes of the contract is that SLES 10 is now the simplest Linux distro jointly supported by the two corporations as a visitor operating system virtualized on Hyper-V, and windows Server 2008 is jointly supported when run as a paravirtualized guest on SLES using the Xen hypervisor covered with the distro.“The interop contract is alive and dealing …”
regardless of the suspicion, many agencies view the interoperability agreement as a favorable step and are satisfied to take expertise of the benefits it offers. “The interop contract is alive and dealing, and the indisputable fact that it's a protracted term agreement is respectable information,” says Nick Leake, Director of Operations and Infrastructure at ITV, a UK-primarily based commercial broadcasting enterprise which runs about 200 windows servers and a hundred SLES servers.
ITV has taken abilities of the settlement between Microsoft and Novell to buy discounted guide coupons for SLES, however Leake says this didn't have an impact on his determination to put into effect SLES in the first region. “We made the decision four years ago, before the Novell - Microsoft interop settlement,” he says. “We conducted an assessment process before making the conscious decision to go with SUSE. We chose not to go with crimson Hat because they don’t have the same engagement degree with purchasers as SUSE, and when the Microsoft Novell deal came along [it] comfortably established that we had made the appropriate choice.”
Leake also says that the skill to manage SLES from within Microsoft’s device core is terribly essential—youngsters ITV opted to make use of Novell’s Zenworks to control each platforms. He says help for the working programs in every other’s digital environments is also advisable.
As Linux turns into more and more authorized it’s doubtless that combined facts middle environments will turn into further and further typical. What’s greater, the strains between distinct platforms will become extra blurred as virtualization—together with VMware’s vision of servers that can also be moved inside an inside cloud and out to exterior cloud carrier providers - and more suitable interoperability make it feasible to deal with windows and Linux servers—each actual and digital—comfortably as computing supplies which are provisioned and managed with the equal equipment in the equal method.
Oracle and Intel are in a excessive-stakes spat over the way forward for Intel’s Itanium chip. Oracle introduced last evening that it had stopped all construction on Intel’s Itanium, a 64-bit heavy-duty computing microprocessor, because Intel expressed vulnerable assist for it. Intel’s chief government shot again that Intel completely supports Itanium.
In a press remark, Oracle referred to, “Intel administration made it clear that their strategic focus is on their x86 microprocessor and that Itanium turned into nearing the end of its life.” That’s a big blow to Intel’s excessive-end computing investments, because Intel has invested billions of bucks in the application due to the fact 1994. At stake is the future route of the excessive end of chip technology.
Oracle has its own pursuits at heart. Oracle now owns sun Microsystems, a hardware and chip business that is now run by co-president Mark Hurd, former CEO of Hewlett-Packard. whereas Oracle was once a pure application enterprise, now it makes hardware and chips that compete without delay with Intel’s Itanium chip.
but the lack of Oracle will harm Intel, because it isn’t the only one to desert Itanium. Microsoft and RedHat deserted making optimized utility for Itanium final yr. Microsoft spoke of that ultimate yr’s windows Server 2008 R2 became the last operating gadget to guide the Intel 64-bit chip, whereas RedHat’s last guide was business Linux 6.
HP-UX is still the only massive supporter of Itanium, from an operating device view. HP dominates the marketplace for Itanium-based servers. speaking to Cnet, Oracle CEO Larry Ellison referred to five years in the past, “There is not any greater crucial platform for Oracle than HP and Itanium.”
all over his own method talk last week, HP CEO Léo Apotheker didn’t say anything about Itanium. but HP nevertheless observed Oracle’s stream become “shameless gambit” to damage opponents. HP also said it is carrying on with development on Itanium-primarily based servers and will accomplish that for the next 10 years and it pointed out that sun’s market share is failing.
“Oracle continues to display a pattern of anti-client habits as they circulate to shore up their failing sun server enterprise,” referred to Dave Donatelli, executive vp and established manager, commercial enterprise Servers, Storage and Networking at HP. “HP believes in fair and sincere competitors. competitors is first rate for shoppers, innovation and the industry. we're stunned that Oracle would put organizations and governments at risk whereas costing them lots of of millions of bucks in lost productivity in a shameless gambit to restrict reasonable competitors.”
Intel is still promotion its subsequent-era Itanium chips, as Intel CEO Paul Otellini mentioned today. In February, Intel unveiled its 10th-era Itanium chip, code-named Poulson, a beast of a chip with 3 billion fundamental components called transistors.
“We stay firmly dedicated to providing a aggressive, multi-generational roadmap for HP-UX and different operating system valued clientele that run the Itanium architecture,” Otellini referred to.
The Itanium has had an extended rollercoaster history. began as a joint venture with HP in 1994, the first chip was a relic of an age when vigor consumption didn’t remember. It turned into purported to debut in 1999, however the code-named Merced chip eventually got here out in 2001, simply in time for the publish-9/eleven recession. Intel’s fundamental competition was its own 32-bit Xeon chips, which have been faster at operating 32-bit application than the 64-bit Itanium become. So the awesome migration of computing from 32-bit to sixty four-bit didn’t turn up for the hundreds, as had originally been expected, and Intel delivered 64-bit expertise into its Xeon line-up.
Intel persisted to make investments, difficult the shrinking number of gamers in the reduced-instruction set computing (RISC) computing company equivalent to sun Microsystems and IBM. Intel says that it continues to be attacking the $15 billion RISC market with Itanium. in the meantime, superior Micro gadgets seized its opportunity to get a foothold in 32-bit server chips and it has succeeded in grabbing a bit of that market.
Intel’s new Poulson chip is slated to return out some time sooner or later, as will a further one code-named Kittson. Otellini talked about these chips are on time table.

In my last tip, I compiled a list of the top 50 Unix commands. Each of the commands I discussed are available on...
the top three Unix variants: Solaris, AIX and HP-UX. In this article, I'll walk you through the history of these Unix flavors, discuss some their fundamental differences and close with a command table comparison of important tasks.
Sun SolarisSolaris, Sun's Unix version, was actually the successor of SunOS, going back to1992. SunOS was originally based on the BSD flavor of Unix, while SunOS versions 5.0 and later are based on Unix System V Release 4 (rebranded as Solaris).
How did this happen? Let's go further back in time. SunOS version 1.0 was introduced in 1983 with support for Sun-1 and Sun-2 systems. Version 2.0 was introduced in 1985 -- its claim to fame was virtual file system (VFS) and NFS. In 1987, AT&T and Sun announced that they would work together on a project to merge System V and BSD into one release, based on SVR4. Solaris 2.4 was Sun's first Sparc/x86 release. The last release of SunOS was version 4.1.4 in November 1994. Solaris 7 was its first 64-bit Ultra Sparc release and added native support for file system metadata logging. Solaris 9, introduced in 2002, added support for Solaris Volume Manager and Linux capabilities. Solaris 10 was first introduced in 2005, which has a number of innovations, including support for its new ZFS file system, Solaris Containers and Logical Domains.
Solaris is presently up to version 10; the latest update was released in October 2008. Among its innovations is support for paravirtualization, where Solaris 10 is used as a guest in Xen-based environments.
Fundamental differences and unique characteristics. Solaris is free and open source, distributed through the OpenSolaris operating system. Solaris is a more command-line based Unix operating system than HP-UX or AIX. As a practical matter, it does not have anything comparable to System Administration Manager (SAM) on HP-UX or System Management Interface Tool (SMIT) on AIX. Solaris runs on Sparc and x86 environments. It also has the newest file system around -- ZFS, which has made great strides in recent years, including the ability to now use it as its root file system. ZFS has the potential to be the best all-around Unix file system. Solaris has many ways to implement virtualization, including Containers/zones, xVM Server, Logical Domains and hardware partitioning.
Hewlett-Packard HP-UXHP-UX, Hewlett-Packard's Unix, was originally based on System V release 3. It initially ran exclusively on PA-RISC HP 9000 platform. Version 1 of HP-UX was released in 1984. Version 9, introduced its character-based graphical user interface (GUI), SAM, from which one administrates the system. Version 10, introduced in 1995, brought changes in the layout of the system file and directory structure, making it similar to AT&T SVR4. Version 11 was introduced in 1997 and was HP's first release to support 64-bit addressing. In 2000, it was rebranded to 11i, when HP introduced operating environments, bundled groups of layered applications for specific IT purposes. In 2001, Version 11.20 introduced support for Itanium systems. HP-UX was the first Unix that used Access Control Lists (ACLs) for file permissions and was also one of the first to introduce built-in support for Logical Volume Manager. Today, HP-UX uses Veritas as its primary file system due to the close partnership between Veritas and HP. HP-UX is currently up to release 11iv3, update 4.
Fundamental differences and unique characteristics. HP-UX is the first of the Unix systems to allow its customers to purchase specific operating environments. For example, if you are looking for its high availability (HA) product Serviceguard, you would purchase the specific product that bundles in HA. HP-UX is the only version that uses a third-party file system -- Veritas (Sun used to offer this many years ago). HP has many forms of virtualization, including nPartitions, vPars, Integrity Virtual Machines (IVMs) and resource partitions. This does have a tendency to confuse some folks because there are so many choices. HP-UX runs on both HP 9000s and Integrity Itanium systems. HP-UX 11v3 can support up to 128 processor cores. HP-UX provides for a very strong command line in addition to its menu bases system, SAM. Performance tuning using kctune is in many ways simpler to what AIX and Solaris offer.
IBM AIXAIX was introduced by IBM in 1986. While it is based on Unix System V, it also has BSD roots and, more than any other flavor, is a hybrid of both. AIX is the first OS to introduce a journaled file system (JFS). It was also the first to have an integrated Logical Volume Manager (LVM). IBM first ported AIX to its RS/6000 platform in 1989. Version 5L was a breakthrough release introduced in 2001 that provided for Linux affinity and logical partitioning with the Power4 servers. In 2004, AIX introduced virtualization in AIX 5.3. Advanced Power Virtualization (APV) offered micro-partitioning, shared processor pools and Symmetric multi-threading. In 2007, IBM enhanced its virtualization product, coinciding with the release of AIX 6.1 and the Power6 architecture. It also rebranded APV to PowerVM. The AIX enhancements included a form of workload partitioning called WPARs, which are similar to than Solaris zones/Containers but with better functionality. The latest release is AIX 6.1.
Fundamental differences and unique characteristics. IBM is widely recognized as having the best virtualization product on the midrange, PowerVM. Some recent innovations include live application mobility (allowing one to fail over working partitions without taking downtime), Active Memory Sharing and multiple shared processor pools. No other flavor of Unix can boast these virtualization characteristics, nor can they match IBM's 40-year history of virtualization -- PowerVM has evolved from mainframe/System z virtualization.
AIX runs only on IBM Power Systems -- easily the most powerful of midrange Unix servers. IBM sells the fact that AIX runs exclusively on Power as a plus because it is fully optimized on this architecture and it has a clear road map around which the company adheres to religiously. It should also be noted that one can run both Linux and AIX partitions on this platform. Its LX86 virtualization add-on allows one to run x86 Linux applications that are not ported to the Power architecture. AIX has always had an integrated logical volume manager, unlike other flavors that require add-on products. AIX is the only Unix that has continued to grow market share in recent years, partly because of the capabilities of its Power hardware that continues to lead the field in reliably, availability and scalability.

Many commercial Unix vendors have enhanced backup tools with decent error recovery built in. AIX has the aptly named backup and restore, while HP-UX has fbackup and frecover. Those, too, unfortunately, lack speed and user-friendliness, although, in the case of these vendors, menu-driven backup tools are provided through system administration menus.
To address this problem, many commercial vendors have entered partnerships with third-party tools to be delivered as part of their OS. Sometimes these tools are trial versions that require full licensing for continued use. Freeware tools are also available, particularly in the case of Linux. In fact, for the administrators running Linux, the field of choice is increasing at an incredible pace. Keep in mind, however, that many GNU tools will compile and run just fine on commercial Unixes.
What are the options and how do you decide what to use? Why pay for a package when others are available for the cost of a download?
I'll tell you a secret. Some pretty slick commercial packages are also available free of charge, provided that you use them in non-profit, non-commercial environments. For example, Enhanced Software Technologies makes BRU (stands for "Backup and Restore Utility), an incredibly easy-to-use, yet powerful and reliable backup utility. The difference is that the personal (or free) edition will not back up remotely mounted drives or Samba shares, or allow the use of remote tape drives. If you are running a single server at home, this is still a pretty good deal. Another contender for slick and powerful, Arkeia from Knox Software, will let you back up two Windows 9x clients. Another free backup utility that provides great commercial features like indexes stored at the beginning of the tape and graphical search tools is taper, which is designed specifically for Linux.
Free tools offer the hard-to-beat argument of low price while still providing reliability. Commercial tools generally provide maturity and easy to use interfaces. Multiplatform support is another issue. If you need to work with a variety of operating systems and you want to maintain a common backup strategy and set of tools across your enterprise, you will likely have to spend the money. For instance, imagine a network of several Windows workstations, a Solaris Web server, an AIX machine, a DGUX server, a couple of NT boxes, and a Novell server. This kind of mixed environment is not unusual, so many commercial vendors will take this into account. For instance, Legato provides software that works in precisely this kind of environment with a central server that backs up remote clients across the network. So does Arkeia, mentioned earlier. Furthermore, some of these advanced tools enforce good tape rotation practices with strict, built-in rule sets.
Even in this complex environment, it's not so cut and dry. Enter AMANDA, the "Advanced Maryland Automated Network Disk Archiver," a freeware tool developed at the University of Maryland. With AMANDA, you set up a central server with a high-capacity tape drive to back up multiple network connected hosts. With Samba, AMANDA can also back up Windows 9x workstations. This is a powerful, multiplatform, network backup solution that costs nothing other than the time to download, compile, and learn.
Some of these network packages use multiple network streams so that several machines back up at the same time. Sure, it sounds great, but there are costs. In the case of a commercial package, there are the obvious software costs of per-client licensing, but that's only one consideration. What about the drain on your network? If you back up during the day or use multiple network streams to do the backup, you may find network applications to be quite slow. Does your network backup solution suddenly require that you invest in a fibre network to take up the slack? What about data recovery, the very reason for backups in the first place? When the inevitable happens and you must recover from a crash, you will likely need to rebuild a working, networked system before you can even consider getting at your data. Many large-scale network backup solutions are better at providing access to individual files than completely restoring a crashed server. You may still need to do regular OS backups and maintain snapshot configurations of your system so that you can re-create filesystems, devices, network addressing, and so on.
HP decided to help the Linux file system innovation by open sourcing its Tru64 Advanced File System, or AdvFS. This file system comes from Digital Unix (created by Digital Equipment Corporation) and is used by HP customers in mission-critical deployments. After several acquisitions, HP created HP-UX, a flavor of Unix, with its own file system. Tru64 AdvFS was offered to DEC (acquired by Compaq ten years ago), Compaq and HP customers. Compaq and HP became one single company in 2002.
HP decided to use the second version of the GPL license for its file system, so it can be compatible with the license used by the Linux kernel (which also uses GPLv2). A developer can take all the parts they want from AdvFS and use them in different applications.
Martin Fink, senior vice president and general manager, Business Critical Systems at HP, said: "To ensure the highest levels of data security and availability, Linux customers need full and immediate access to established technology. We continue to invest our engineering resources in the development of that technology, while working with the open source community to ensure accessibility and seamless integration."
AdvFS is a high performance journaling file system that allows fast recovery after a system crash. Thanks to its dynamic structure, one can manage the file system on the fly and once more, on the fly, system snapshots can be created.
AdvFS's storage pool is called "file domain" (made up of block devices) and its logical file systems are called "file sets". The latter can be balanced, which means that the content on these sets can be balanced across physical volumes. The snapshots, or clones, allow a system administrator to easily create on-line backups; an interesting feature of AdvFS is the one that allows a sysadmin to add or remove block devices from a file domain even if the latter has active users. This feature is really good when it comes to migrating to larger devices or from faulty hardware without shutting down the system.
This file system supports volumes that have a maximum size of 16 TB and the names of the files must not have more than 255 bytes in length.
