100% Mac

On the eve of the MacWorld keynote, I thought it would be appropriate to highlight the single application which enabled me to complete my "switch" from a PC to a Mac: Parallels.

For those who may not know, Parallels is a virtualization environment for the Intel Macs. It enables you to run an operating system - from Windows to Linux to DOS - within Mac OS X. The entire guest operating system is stored in a single file, which can easily be backed up and/or moved around easily.

I first saw Parallels at a client, where Ben Rudolph from the Parallels team was getting ready to demo it. He turned on his MacBook Pro, fired up Parallels, and then stared up a pre-release version of Vista. He looked at me and said, "Pretty cool, eh?" My only reply was "Why?"

He chuckled, but went on to claim that even a pre-release version of Vista worked with their software. From a tecnical point of view, it was quite impressive, as having Vista gives you access to all of its new innovations, such as the new search, gadgets, and the 3-d Chess game.

So it was not a surprise to me that Parallels was one of the 1st applications I bought for my new MacBook. It has paid for itself many times over already. First of all, it just works. Installing it is a breeze, but what's more impressive is installing a guest OS is even simpler. In fact, its easier to install Windows XP in Parallels than it is to install it on an Intel machine. Seriously. Have a look at the one screen which you'll need to fill out:


The next screen simply asks for a name for the VM you are about to create. That's it. Sit back and enjoy your install!

Once I installed my copy of XP in Parallels, I was quick to download Oracle 10gR2, Oracle HTTP Server & Oracle Application Express. All three of these products installed flawlessly in Parallels. And with bridged networking, I can use my Mac browsers and OS X version of SQL Developer & SQL*Plus to access the Oracle instance in Windows XP.

As soon as I verified that my configuration was working, I immediately backed it up. Why? If I ever need to start with a clean install of Oracle 10gR2 & Apex, I could restore this clean configuration and be up in running in minutes with nothing to re-install. Anyone who has worked with Oracle more than a few days knows how valuable being able to revert to a clean install can be.

And that's exactly what one of the first true tests of Parallels was. We hit an obscure error with an Apex application that I was building for a client. Initially, signs led to something with the character set of the database. The size of the HTTP packets we were getting were inconsistent with what we expected. We didn't have the resources to create a new database from scratch in a different character set in order to further troubleshoot the issue. Or did we.

Enter Parallels. I simply made a copy of my "clean" configuration, fired up the DBCA, created a new database with a different character set, changed the DAD configuration, and we were able to rule out the character set in about an hour. No additional hardware was required, save for a few GB of disk space, which was quickly reclaimed once we knew the character set was not the issue.

Parallels has also proved itself a demonstration environment. A couple of months later, I was teaching an Apex class just outside of Providence, RI. Someone asked me if Apex & Oracle XML Publisher could be integrated. I've always thought so, and have even been told so by some who claim to have done it. But I've never done it myself, which tends to make me a bit skeptical.

So after dinner, I copied my clean configuration once more, found a nice install guide for XML Publisher on OTN, and started installing. After downloading & configuring Tomcat, installing XML Publisher Workstation & Server, and about 2 hours later, I had it up and running on my Mac. Since Apex was already installed in my configuration, the next task was to figure out how to get the two to work together. (more details on this in an upcoming paper which I am putting the finishing touches on)

The next day, I started the class with a demo of Oracle XML Publisher integrated with Oracle Apex. It was hard to tell what was more amazing to the students - that I was able to get these two products working together, or that I had a Start button on a laptop with a big Apple logo on the back. The demo somehow concluded with a quick tour of iLife. I may have actually sold a couple of Macs that day.

In addition to using Parallels for server based applications, it has proven extremely valuable for client applications as well. Most people hesitate to switch to a Mac because there are always "a couple" of Windows applications which they cannot live without. They don't necessarily use these applications every day, but when they do need them, they cannot be with out them.

Two of those must-have applications for me are MS Access & GotoMeeting.

As much as I hate Access, I need to have it, as I get quite a few Access databases that people want to convert to Oracle Apex. Without the ability to read those databases, I was dead in the water. With Parallels, its a breeze to open MS Access databases. In fact, I have all of MS Office installed, just in case I need it.

Since most of my clients are not local, I need to share screens with them for demos, prototypes, etc. From what I could tell, there just isn't any way to do this on a Mac. Running GotoMeeting on Parallels was a breeze. I don't notice any performance issues at all, and have hosted meetings for multiple clients, all of them blissfully unaware that I am running Mac OS X.

What's really impressive is that the Parallels team is not resting on their laurels. They have churned out 3 betas in about as many months. Perhaps the coolest of the new features is something called Coherence.

Coherence lets you run a single Windows window as if it were a Mac window. Sure, it still looks and feels like a Windows window, but it is free of the bounds of the Mac window which typically confines all things Windows. Below, you can see Apple's home page displayed in both MSIE 6.0 and Firefox for OS X.


Parallels was and is the missing link for me and many IT professionals who were wanting to make the switch to Apple, but just couldn't do it. It finally gives us the ability to run a platform on a platform - be it for server or client applications, Linux or Windows. And most of all, in true Mac fashion, it just works.

Yes, you're right. Parallels is extraordinary. Like you said, it just works. I haven't experienced any problem in weeks. A friend of mine is using a single mini mac (2GB RAM) for a "linux setup and installation" class. He installs 4 instances of Linux and a very local network, fully functionnal, with NFS between the VMs. On a single $1000 device thanks to Parallels.
I think all this existed before, it was called VMWare. Parallels just brought the Mac's ease of use.
Macbook are just so pretty compare to other laptops!
Hi Scott,
I'm an Oracle Developer and have just bought a Mac.
Trying to determine the right software/versions of software that I should be running and wanted to ask your advice.
I'm an apps tech developer so use everything from Oracle Developer 6, Workflow, Disco, Designer and JDeveloper. I know JDev and SQLDeveloper run on Mac to they're fine, however can you suggest the right config to run the rest.
Would running Windows 7 Professional in Parallels be best (so can emulate Windows XP for the likes of Workflow)? Any thoughts on Parallels vs VMWare Fusion for Oracle software?
What other recommendations do you have?
Your advice is very much appreciated!
Cheers

Hi Scott,
Further to my recent post, if you are able to email me on knasskau@iinet.net.au with some advice, that would be hugely appreciated!!!

Karen,

I'd recommend the VMware/Parallels route, as there's just too much Oracle-specific stuff in your list.

I use VMware now, but have heard good things about both Parallels & VirtualBox as well.

Thanks,

Spaced Out

A while back, I wrote about how to give the Universal Theme a face lift.  If you follow the steps in that post, the base font for an APEX application with the Universal Theme can easily be changed.

While that's all well and good, sometimes you only want to change the font for a report, not the entire page.  One of the applications that I'm building contains a number of IRs based mostly on log data.  Thus, having that data in a monospaced font would make it a whole lot easier to read.

You can search Google Fonts for monospaced fonts by selecting only that option on the right-side menubar.  You can also opt for the standard yet kinda boring Courier and achieve the same thing.

To implement this in your application, follow the steps in my other post, but stop shy of the final step.  Instead of pasting in the text that I specify, paste in the following to the Custom CSS field in Theme Roller, using the name of the font you selected for the font-family:

.a-IRR-table tr td { font-fam…

Thanks, ODC (Oracle Developer Community)!

I owe a lot of thanks to the ODC - which stands for Oracle Developer Community.  What is ODC?  You may remember it as OTN, or the Oracle Technology Network.  Same people, different name.  Why they changed it I can't say.  People just liked it better that way... (love that song)

In any case, what am I thankful for?  A lot.  To start, the tools that I use day in and day out: SQL Developer, ORDS, Oracle Data Modeler, SQLcl and - of course - APEX.  Without these tools, I'm likely on a completely different career path, perhaps even one that aligns more closely with my degree in television management.

While the tools are great, it's really the people that make up the community that make ODC stand out. From the folks who run ODC and the Oracle ACE program to the developers and product managers who are behind the awesome tools, the ODC community is one of, if not the greatest asset of being involved with Oracle's products.

If you have yet to get more involved with this communi…

Whose Deck is it Anyways?

This year at KScope, we're going to try something new.  And fun.  And funny to watch - we hope.  It's called "Whose Deck is it Anyways?", and will occur on Sunday at 8:30pm.  It's only 30 minutes, but it will likely be the best 30 minutes of the conference.  Or at least the most embarrassing.

Here's what we're going to do: the will be four 5-minute presentations - one on each of the following: BI, EPM, Database & APEX.

Sound interesting?  Probably not.  We get that, too.  So here's what we did.

Each 5-minute session will be presented by a non-expert.  For example, it's highly likely that I'll be presenting on BI or EPM.

To make it even better, each slide deck will be prepared by the corresponding expert.  So again, it's highly likely that my slide deck's creator will be either Stewart Bryson or Edward Roske.  If nothing else, this session will be a crash course in how not to make cohesive, easy to read slides.

Interested now?  Ya,…
