  • Profit's COLLABORATE 10 Session Selections

    - by Aaron Lazenby
    COLLABORATE 2010 is a mere 11 days away (thanks for the reminder @ocp_advisor). Every year I publish my a list of the sessions I think reflect some of the more interesting people/trends in enterprise IT. I should be at all of these sessions, so drop by for a chat--I'll be the guy tapping out emails on my iPad... Monday, April 19 9:15 a.m. - Keynote: Transforming Customer Value, Delivering Highest Customer Service Location: Keynote Hall I never miss Charles Phillips when he speaks--it's one of the best opportunities to get an update on Oracle product developments and strategy. And there's certainly occasion for an update: this will be Phillips' first big presentation since the Oracle + Sun Strategy Update in late January. Phillips is appearing with Oracle Executive Vice President of Development Thomas Kurian which means there should be some excellent information about how customers are using Oracle's complete software and hardware stack to address enterprise IT challenges. The session should provide some excellent context for the rest of the week's session...don't miss it. 10:45 a.m. - Oracle Fusion Applications: Functional Overview Location: South Seas FI met Basheer Khan at COLLABORATE 08 in Denver and have followed his work ever since. He's a former member of the OAUG Board of Directors, an Oracle ACE, and a charismatic enterprise IT expert. Having worked with the Oracle Usability Advisory Board, Basheer should have some fascinating insights to share about the features and interface of Oracle's Fusine Applications. This session, along with Nadia Bendjedou's "10 Things You Can Do Today to Prepare for the Next Generation Applications" (on Tuesday, April 20 8:00 a.m. in room 3662) should give attendees the update they need about Oracle's next-generation applications.   1:15p.m. - E-Business Suite in the Amazon Cloud Location: South Seas HI did my first full-fledged cloud computing coverage at last year's COLLABORATE show (check out my interview with Oracle's Bill Hodak), where I first learned about Amazon's EC2 offering. I've since talked with several people who have provisioned server space on Amazon's cloud with great results. So I'm looking forward to watching the audience configure an instance of the Oracle E-Business Suite release 12 on the cloud while Chuck Edwards from Blue Gecko drives. This session should take some of the mist and vapor out of the cloud conversation.2:30 p.m. - "Zero Sign-on" to EBS - Enabling 96000 Users to Login to EBS Without User Maintenance Location: South Seas HI'll be sitting tight in South Seas H for the next session on Monday where Doug Pepka, a ten-year veteran of communications giant Comcast, will be walking attendees through a massive single sign-on (SSO) project across the enterprise. I'm working on a story about SSO for the August issue of Profit, so this session has real practical value to me. Plus the proliferation of user account logins--both personal and professional--makes this a critical usability/change management issue for IT leaders planning for successful long-term IT implementations.   Tuesday 8:00 am  - Information Architecture for Men in Kilts Location: SURF AGetting to a 8:00 a.m. presentation is a tall order in Las Vegas, but presenter Billy Cripe will make it worth your effort. Not only is the title of this session great, but the content should appeal to any IT strategist looking to push the limits of Web 2.0 technologies in the enterprise. Cripe is a product management director of Enterprise 2.0 and Enterprise Content Management at Oracle, author of Reshaping Your Business with Web 2.0, and a prolific blogger--he knows how information architecture is critical to and enterprise 2.0 implementation.    10:30a.m. - Oracle Virtualization: From Desktop to Data Center Location: REEF FData center virtualization is still one of the best ways to reduce the cost of running enterprise IT. With the addition of Sun products, Oracle has the industry's most comprehensive virtualization portfolio. I must admit, I'm no expert in this subject. So I'm looking forward to Monica Kumar's presentation so I can get up to speed.   Wednesday 8:00 a.m. - The Art of the Steal Location: Mandalay Bay Ballroom JMany will know Frank Abagnale from Steven Spielberg's 2002 film "Catch Me if You Can." The one-time con man and international fugitive who swindled $2.5 million in forged checks went on to help U.S. federal officials investigate fraud cases. Now the CEO of Abagnale and Associates, he has become an invaluable source to the business world on the subject of fraud and fraud protection. With identity theft and digital fraud still on the rise, this session should be an entertaining, and sobering, education on the threats facing businesses and customers around the world. A great way to start Wednesday.1:00 p.m. - Google Wave: Will it replace e-mail as we know it today? Location: SURF EBy many assessments (my own included), Google Wave is a bit of an open collaboration failure. It may seem like an odd reason for me to be excited about this session, but I'm looking forward to the chance to revisit the technology. Also, this is a great case study in connecting free, available Internet tools to existing enterprise computing environments--an issue that IT strategists must contend with as workers spreads out and choose their own productivity tools.

  • Availability Best Practices on Oracle VM Server for SPARC

    - by jsavit
    This is the first of a series of blog posts on configuring Oracle VM Server for SPARC (also called Logical Domains) for availability. This series will show how to how to plan for availability, improve serviceability, avoid single points of failure, and provide resiliency against hardware and software failures. Availability is a broad topic that has filled entire books, so these posts will focus on aspects specifically related to Oracle VM Server for SPARC. The goal is to improve Reliability, Availability and Serviceability (RAS): An article defining RAS can be found here. Oracle VM Server for SPARC Principles for Availability Let's state some guiding principles for availability that apply to Oracle VM Server for SPARC: Avoid Single Points Of Failure (SPOFs). Systems should be configured so a component failure does not result in a loss of application service. The general method to avoid SPOFs is to provide redundancy so service can continue without interruption if a component fails. For a critical application there may be multiple levels of redundancy so multiple failures can be tolerated. Oracle VM Server for SPARC makes it possible to configure systems that avoid SPOFs. Configure for availability at a level of resource and effort consistent with business needs. Effort and resource should be consistent with business requirements. Production has different availability requirements than test/development, so it's worth expending resources to provide higher availability. Even within the category of production there may be different levels of criticality, outage tolerances, recovery and repair time requirements. Keep in mind that a simple design may be more understandable and effective than a complex design that attempts to "do everything". Design for availability at the appropriate tier or level of the platform stack. Availability can be provided in the application, in the database, or in the virtualization, hardware and network layers they depend on - or using a combination of all of them. It may not be necessary to engineer resilient virtualization for stateless web applications applications where availability is provided by a network load balancer, or for enterprise applications like Oracle Real Application Clusters (RAC) and WebLogic that provide their own resiliency. It's (often) the same architecture whether virtual or not: For example, providing resiliency against a lost device path or failing disk media is done for the same reasons and may use the same design whether in a domain or not. It's (often) the same technique whether using domains or not: Many configuration steps are the same. For example, configuring IPMP or creating a redundant ZFS pool is pretty much the same within the guest whether you're in a guest domain or not. There are configuration steps and choices for provisioning the guest with the virtual network and disk devices, which we will discuss. Sometimes it is different using domains: There are new resources to configure. Most notable is the use of alternate service domains, which provides resiliency in case of a domain failure, and also permits improved serviceability via "rolling upgrades". This is an important differentiator between Oracle VM Server for SPARC and traditional virtual machine environments where all virtual I/O is provided by a monolithic infrastructure that itself is a SPOF. Alternate service domains are widely used to provide resiliency in production logical domains environments. Some things are done via logical domains commands, and some are done in the guest: For example, with Oracle VM Server for SPARC we provide multiple network connections to the guest, and then configure network resiliency in the guest via IP Multi Pathing (IPMP) - essentially the same as for non-virtual systems. On the other hand, we configure virtual disk availability in the virtualization layer, and the guest sees an already-resilient disk without being aware of the details. These blogs will discuss configuration details like this. Live migration is not "high availability" in the sense of "continuous availability": If the server is down, then you don't live migrate from it! (A cluster or VM restart elsewhere would be used). However, live migration can be part of the RAS (Reliability, Availability, Serviceability) picture by improving Serviceability - you can move running domains off of a box before planned service or maintenance. The blog Best Practices - Live Migration on Oracle VM Server for SPARC discusses this. Topics Here are some of the topics that will be covered: Network availability using IP Multipathing and aggregates Disk path availability using virtual disks defined with multipath groups ("mpgroup") Disk media resiliency configuring for redundant disks that can tolerate media loss Multiple service domains - this is probably the most significant item and the one most specific to Oracle VM Server for SPARC. It is very widely deployed in production environments as the means to provide network and disk availability, but it can be confusing. Subsequent articles will describe why and how to configure multiple service domains. Note, for the sake of precision: an I/O domain is any domain that has a physical I/O resource (such as a PCIe bus root complex). A service domain is a domain providing virtual device services to other domains; it is almost always an I/O domain too (so it can have something to serve). Resources Here are some important links; we'll be drawing on their content in the next several articles: Oracle VM Server for SPARC Documentation Maximizing Application Reliability and Availability with SPARC T5 Servers whitepaper by Gary Combs Maximizing Application Reliability and Availability with the SPARC M5-32 Server whitepaper by Gary Combs Summary Oracle VM Server for SPARC offers features that can be used to provide highly-available environments. This and the following blog entries will describe how to plan and deploy them.

  • How to mount a LOFS in Solaris that doesn’t cross mountpoints

    - by jcea
    I need to access my "root" ZFS dataset to delete a file under "/var". But "/var" is overlayed by another ZFS dataset. Since these are system datasets I can't "umount" them while the machine is running. And I want to avoid to reboot the system in "failsafe" mode, since this is a production machine. Teorically ZFS would refuse to mount "/var" dataset over the underlying "/var", because it is not empty. But it works, possibly because they are system datasets mounted early in the boot process. But having the underlying "/var" not empty is preventing me to create an ABE (Alternate Boot Environment), so patching is risky, and I can't upgrade my system using Live Upgrade. The machine is remote. I have an IP KVM, but I rather prefer to avoid booting this machine in "failsafe" mode, if I can. I know there is a file in "/var/" because I can snapshot the "root" dataset and check it. But snapshots are read-only, so I can't get rid of the file. I tried "mkdir /tmp/zzz; mount -F lofs / /tmp/zzz", but when I go to "/tmp/zzz/var", I see the "/var" dataset, not the underlying "root" dataset. That is, the LOFS is crossing mountpoints. I would usually like it, but not this time!. Any suggestion, beside rebooting the machine in "failsafe" and mess with it thru the IP KVM?

  • Windows Server 2008 R2 install reboots unexpectedly during "Completing installation" phase

    - by knda
    I am attempting to install Windows Server 2008 R2 onto a Cisco UCS C201 M2 rack mounted server but am having major difficulties and wondering if anyone has some insight or items they could recommend for me to look at to get this one resolved. Installation is being attempted via the Cisco remote console (using CIMC's Virtual dvd-rom).. following the first phase of Setup where the installation files are copied to the target hard drive, then a reboot occurs to load Setup from the HDD, mid-way in the "Completing Installation" phase the system then reboots unexpectedly. System configuration Cisco UCS C201 M2 (2RU rack mounted server) 16GB RAM, 2x 73GB 15K SAS, 4x 300GB 10k SAS Add-on cards - Intel quad-port GigE card (no fibre channel cards) Storage - LSI MegaRAID SAS 9261-8i. onboard SATA is disabled (no SATA drives connected) KVM - Belkin No physical DVD-ROM.. :( I have... Run memtest86+, no RAM faults Disabled/enabled SATA support (BIOS) Attempted install from USB DVD-ROM, no effect Attempted unattended install scripted via Cisco Configuration Manager DVD provided Removed Belkin KVM in case that was causing drama Discovered that the Cisco website is "awesome" for searching for PDFs/Drivers cough, reverted back to Google Downloaded latest LSI drivers from LSI's site and used during Server 2008 install checked Windows ISO against checksum's from MS site checked Windows ISO by using it for an install in a VM Running out of ways to troubleshoot this as I am not sure how to enable any sort of 'verbose' mode during the setup process. Next step I have planned is to remove the Intel NIC and try the installation again.. Edit: Problem was the "Cisco INTEL QUAD PT GBE" (1000/PT) .. will have to see if this card is faulty or if it's just drivers.. thanks for the help.

  • Libvirt / QEmu Machine Fails and Refuses Restart Because of Memory Allocation Errors

    - by Elmar Weber
    I'm having a problem with libvirt. On a system restart all virtual machines (VMs) are started without a problem and keep running. Then at some point in time a set of machines shuts down according to their log. When I try to restart the machine, I'm getting an error that the memory allocation failed, although more than enough memory is free. server ~ # free total used free shared buffers cached Mem: 16176648 16025476 151172 0 285432 950300 -/+ buffers/cache: 14789744 1386904 Swap: 0 0 0 server ~ # virsh start zimbra error: Failed to start domain zimbra error: Unable to read from monitor: Connection reset by peer server ~ # tail -n 4 /var/log/libvirt/qemu/zimbra.log LC_ALL=C PATH=/usr/local/sbin:/usr/local/bin:/usr/bin:/usr/sbin:/sbin:/bin QEMU_AUDIO_DRV=none /usr/bin/kvm -S -M pc-0.12 -enable-kvm -m 3072 -smp 2,sockets=2,cores=1,threads=1 -name zimbra -uuid d05ddb7a-83c4-a77b-d8bc-a322648520cf -nodefconfig -nodefaults -chardev socket,id=charmonitor,path=/var/lib/libvirt/qemu/zimbra.monitor,server,nowait -mon chardev=charmonitor,id=monitor,mode=control -rtc base=utc -no-shutdown -drive file=/var/lib/libvirt/images/zimbra.img,if=none,id=drive-ide0-0-0,format=raw -device ide-drive,bus=ide.0,unit=0,drive=drive-ide0-0-0,id=ide0-0-0,bootindex=1 -netdev tap,fd=19,id=hostnet0 -device rtl8139,netdev=hostnet0,id=net0,mac=52:54:00:21:a9:ad,bus=pci.0,addr=0x3 -chardev pty,id=charserial0 -device isa-serial,chardev=charserial0,id=serial0 -usb -vnc 192.168.1.2:25 -k de -vga cirrus -device virtio-balloon-pci,id=balloon0,bus=pci.0,addr=0x4 char device redirected to /dev/pts/2 Failed to allocate 3221225472 B: Cannot allocate memory 2012-07-06 08:42:56.076+0000: shutting down server ~ # uname -a Linux server 3.2.0-26-generic #41-Ubuntu SMP Thu Jun 14 17:49:24 UTC 2012 x86_64 x86_64 x86_64 GNU/Linux The system is a Ubuntu 12.04 server.

  • How to configure networking on an appliance such that it can plug and play on any corporate network?

    - by Joshua Lim
    I had a chance to configure a Moxa NPort device server appliance on my client's network, it was very easy to do so, done in just 2 minutes. Here's what I did:- The Moxa device server had a preset IP address of 192.168.127.254 and subnet mask 255.255.255.0 - http://www.moxa.com/doc/manual/nport/5400/NPort_5400_Series_Users_Manual_v4.pdf Moxa provides a Windows software which I used to "scan" for the device server. It worked like magic! The software returns a list of device servers found. Each device server is identified by MAC address, and by selecting the device server using the software, I can reset the default IP address and subnet mask of that device server! In comparison, during an earlier project, I spent 2 hours trying to get KVM to work for a Windows 7 embedded appliance I'm trying to install in my client's network - http://superuser.com/questions/380305/how-to-configure-windows-7-professional-appliance-pc-on-my-clients-network-usin Prior to that, I have already tried pre-configuring the IP address and subnet mask to the one which my client provided, yet the appliance still can't connect to the client's network! I've also tried cross cable, didn't work either. After KVM worked, I discovered that the network settings were "lost" after I plug the machine into the client's network. Now my question is what can I do to setup my Windows 7 embedded appliance so that it can connect to any network like that the Moxa device server? I tried experimenting this on my network using a Windows machine configured to an IP address of 192.168.127.254 and subnet mask 255.255.255.0, but it doesn't connect to my network that uses 192.168.0.*. :( EDIT: I would like to point out that the Moxa Windows configuration software seems to be able to connect to any Moxa device connected to the network even if it is on a different subnet, as long as the network adapter shows "connected". This is important because the Moxa device has no VGSM port or interface to configure the IP address.

  • How do I keep a bridge enabled on a bonded interface?

    - by jlawer
    I'm working on setting up a pair of CentOS 6.3 servers that will run a couple of KVM vms and have come across a problem setting up a bridge on a bond. I am using Mode 4 (802.3ad) bonding on a pair of stacked Dell Powerconnect 5524 switches connecting to R320 servers. There are 2 links (1 to each switch) that form a Link Aggregation Group (802.3ad / LACP bonding). On top of the bond I have VLAN Tagging. I've verified this is a problem on multiple other bonding modes so it isn't just a mode 4 issue. I am testing what happens when 1 link is dropped (ie switch dies, cable breaks, etc). If I don't have a bridge (for KVM), everything works fine, failover happens as expected. If I have the bridge enabled, it works fine until failover (unplugging a cable). When failover happens /var/log/messages shows the slave link going down, followed within a second by: kernel: br1: port 1(bond0.8) entering disabled state The thing is /proc/net/bonding/bond0 shows the link is up as expected (simply with only 1 slave instead of 2). If I plug the cable back in it recovers and brings the bridge back to an enabled state. I actually have tested this while a ping is occuring and if the timing is right a packet will actually leave the system after the link is lost, but before the disabled message occurs. This disabled state I assumed was STP, but I have disabled STP on the bridge configuration and this issue still occurs. brctl showstp br1 still shows the link as disabled when it is running without a slave. I also switched between the nics in the server (I have 2x Broadcom & 4x intel). It doesn't matter which configuration I have. Does anyone know of a way to force the bridge to stay enabled or why its detecting the bond as disabled, when it isn't?

  • Two monitors with Mac Mini - one displays black despite receiving a signal

    - by alex
    My Mac Mini outputs to my two new monitors - Dell U2311Hs. The LED on the bezel displays blue when receiving a signal, or yellow otherwise. Both screens are displaying blue. It also seems my Mini can see both of them... However, one of them is black. It just displays black, but appears to be receiving a signal (when I turn the Mac off, it then displays No Signal). To make things weirder, on startup, the boot up (white with Apple logo) appears on the right monitor (the one that now displays black). Occasionally, it flickers up on the black screen for 1 second. I have tried Detect Displays. It appears to do nothing. I'm also running a dual monitor KVM. Video connections are DVI-D. How can I fix this situation? Thanks. Update This is the weirdest thing - I used the DVI-D cable that came with the KVM and it seems to have fixed it - I didn't both because it looks identical to any other DVI cable (in form an pin out). So, I will accept an answer if someone can tell me what may be the difference in these cables?

  • ATI Radeon 5670 Won't Show Resolutions over 1400x900

    - by Phil Sandler
    Just got my new Dell computer with Windows 7 and an ATI Radeon 5670. I attached it to my current monitor, which is a Samsung 24" (2443bwt). Windows 7 does not allow me to display in resolutions greater than 1400 x 900. The setup through a VGA cable into the VGA port of the card. The card also has a DVI port, but I need to use the VGA port because a KVM that supports VGA only. My old PC (which is Windows XP, GeForce 8600 video) can display in 1900 x 1200 on the same monitor (which is what I want) and even higher. It does this through a vga cable also connected to the KVM (through the DVI port but using an adapter). I have tried the same setup (DVI = VGA adapter) on the new PC and nothing changed. I have tried: Updating the drivers via Windows "Update Driver" (says they are current) Installing the updated version of the drivers from ATI (made no difference) Installing Powerstrip (all the options I would need for a custom resolution are greyed out) Installing the drivers/software from ATI caused the ATI Catalyst Control Center software to stop functioning, so I can no longer even start it. I have found some references to other people having this problem and instructions on cleaning the software off and reinstalling it (as uninstalling normally doesn't solve it). I will try this tonight. In any case, I didn't see any options in CCC that would allow me to override the settings for max resolution. However I didn't tinker with it too much before I tried updating the drivers, so I may have missed a setting. I contacted Samsung via online chat and they say it's a problem with the video card/driver (of course--what else would they say?). Any thoughts on what else I could try?

  • Would a USB hub work in reverse?

    - by Tim
    Imagine for a moment with a 4 port USB hub. Normally how this would work is the hub has one plug that goes to the computer, then 4 ports that you can plug in other things to (thumb drive, keyboard, mouse etc). I am wondering if I can use it in reverse. So I would have 1 keyboard going in to the hub, and then plug in male to male usb cables from the 4 ports to 4 different PCs, my aim is that when a key is pressed on the keyboard all 4 PCs will receive it as if the keyboard were plugged in to them. Does anyone know if this would work? And if not does anyone have any ideas how I could get the same effect? EDIT: So I am looking for more of a KVM switch type device rather than a USB hub. However all of the KVM switches I've found use some sort of mechanism to select which computer you'll be using. (some are physical switches / buttons, others do it via software "automatically" some how) However I need to have 1 keyboard hooked up to 2 computers and when I press a key on the keyboard I want the keypress to be sent to both computers simultaneously, not to one or the other. Does anyone know if KVMs with this feature exist?

  • The Oracle Enterprise Linux Software and Hardware Ecosystem

    - by sergio.leunissen
    It's been nearly four years since we launched the Unbreakable Linux support program and with it the free Oracle Enterprise Linux software. Since then, we've built up an extensive ecosystem of hardware and software partners. Oracle works directly with these vendors to ensure joint customers can run Oracle Enterprise Linux. As Oracle Enterprise Linux is fully--both source and binary--compatible with Red Hat Enterprise Linux (RHEL), there is minimal work involved for software and hardware vendors to test their products with it. We develop our software on Oracle Enterprise Linux and perform full certification testing on Oracle Enterprise Linux as well. Due to the compatibility between Oracle Enterprise Linux and RHEL, Oracle also certifies its software for use on RHEL, without any additional testing. Oracle Enterprise Linux tracks RHEL by publishing freely downloadable installation media on edelivery.oracle.com/linux and updates, bug fixes and security errata on Unbreakable Linux Network (ULN). At the same time, Oracle's Linux kernel team is shaping the future of enterprise Linux distributions by developing technologies and features that matter to customers who deploy Linux in the data center, including file systems, memory management, high performance computing, data integrity and virtualization. All this work is contributed to the Linux and Xen communities. The list below is a sample of the partners who have certified their products with Oracle Enterprise Linux.

  • Don’t just P2V that server for Testing!

    - by Jonathan Kehayias
    If you use virtualization in your company, at some point in time you might be tempted to perform a Physical-To-Virtual conversion, also known as P2V.  The ability to create a complete working copy of a physical server as a virtual machine is really useful for migrating to a virtualized datacenter, but it can also wreak havoc in your environment if you use it to generate a copy of a server for testing and the only change you make is the name of the server.  The Problem: Consider that you...(read more)

  • “Cloud Integration in Minutes” – True or False?

    - by Bruce Tierney
    The short answer is “yes”. Connecting on-premise and cloud applications “in minutes” is true…provided you only consider the connectivity subset of integration and have a small number of cloud integration touch points. At the recent Gartner AADI conference, 230 attendees filled up the Oracle session to get a more comprehensive answer to this question. During the session, titled “Simplifying Integration – The Cloud & Mobile Pre-requisite”, Oracle’s Tim Hall described cloud connectivity and then, equally importantly, the other essential and sometimes overlooked aspects of integration required to ensure a long term application and service integration strategy. To understand the challenges and opportunities faced by cloud integration, the session started off with a slide that describes how connectivity can quickly transition from simplicity to complexity as the number of applications and service vendor instances grows: Increased complexity puts increased demand on the integration platform As companies expand from on-premise applications into a hybrid on-premise/cloud infrastructure with support for mobile, cloud, and social, there is a new sense of urgency to implement a unified and comprehensive service integration platform. Without getting this unified platform in place, companies face increased complexity and cost managing a growing patchwork of niche integration toolsets as well as the disparate standards mandated by each SaaS vendor as shown in the image below: dddddddddddddddddddd Incomplete and overlapping offerings from a patchwork of niche vendors Also at Gartner AADI, Oracle SOA Suite customer Geeta Pyne, Director of Middleware at BMC presented their successful strategy on how BMC efficiently manages their cloud integration despite disparate requirements from each vendor. From one of Geeta’s slide: Interfaces are dictated by SaaS vendors; wide variety (SOAP, REST, Socket, HTTP/POX, SFTP); Flexibility of Oracle Service Bus/SOA Suite helps to support Every vendor has their way to handle Security; WS-Security, Custom Header; Support in Oracle Service Bus helps to adhere to disparate requirements At BMC, the flexibility of Oracle Service Bus and Oracle SOA Suite allowed them to support the wide variation in the functional requirements as mandated by their SaaS vendors. In contrast to the patchwork platform approach of escalating complexity from overlapping SaaS toolkits, Oracle’s strategy is to provide a unified platform to support disparate requirements from your SaaS vendors, on-premise apps, legacy apps, and more. Furthermore, Oracle SOA Suite includes the many aspects of comprehensive integration beyond basic connectivity including orchestration, analytics (BAM, events…), service virtualization and more in a single unified interface. Oracle SOA Suite – Unified and comprehensive To summarize, yes you can achieve “cloud integration in minutes” when considering the connectivity subset of integration but be sure to look for ways to simplify as you consider a more comprehensive view of integration beyond basic connectivity such as service virtualization, management, event processing and more. And finally, be sure your integration platform has the deep flexibility to handle the requirements of all your future SaaS applications…many of which are unknown to you now.
