How is the backwards compatibility in general? I got a Oracle 10g database running on SL that I am particularly worried about. I got it anyways - will have to do a full backup and find out I suppose. Speaking of 4GB downloads - OS X still does not have something like http://en.wikipedia.org/wiki/Background_Intelligent_Transfer_Service http://en.wikipedia.org/wiki/Background_Intelligent_Transfer... which can utilize priorities, throttling and do idle bandwidth downloads. That means my VOIP calls are screwed until the download is done. Even any of the Apple routers don't do QoS stuff I guess. [Edit] Apparently the backwards compat is not good enough for Oracle :( - -bash: ulimit: max user processes: cannot modify limit: Invalid argument oracle@~$ sqlplus / as sysdba Segmentation fault: 11 oracle@~$ [Edit2] And the scrollbars are throwing me off but there is a setting to revert to old behavior. Xcode no longer works, JVM was removed and downloaded when I tried to use it - App Store doesn't seem to have a 10.7 compatible XCode update yet. Ho hum for the most part and even nightmarish for people using Xcode.

For compatibility in general, http://roaringapps.com/ http://roaringapps.com/ looks like a decent guide. Not sure about Oracle 10g though.

  > It was never part of the base install so that's unsurprising. No, but it was always included along with the install disks. No install disks this time and no X Code. It's worth mentioning.
  - masklinn 15y ago
    I fail to see how it's worth mentioning. Xcode not being included in the Lion DMG is not surprising, it's "no shit": Xcode was never in the OSX image in the first place, why would Lion be any different? The only difference is that 4.1 is not released yet, and thus not currently available. That's it. That it's not part of lion (let alone installed by default) is anything but surprising.
    - alexg0 15y ago
      What is worth mentioning, if you had an earlier version of XCode installed, upgrade to Lion breaks it.
      - masklinn 15y ago
        Wasn't that always the case as well? I don't remember but that seems likely since Apple always releases a new Xcode version synchronized with the main OS.
        alexg0 15y ago
        Can't say, I am recent OS X convert. Took me a second to figure out why all the stuff I installed with brew stopped working. Turned out git somehow got uninstalled/disabled, and brew relies on being able to find gcc in the path, and it was no longer there. Updated to newer XCode to get gcc back, and all is happy.
    - Johngibb 15y ago
      XCode was in fact always included with the OS X images.
      - masklinn 15y ago
        No. Xcode was on a separate disk, never on OSX's. Again, Xcode was never a part of the base install or of the OSX image. edit: wow, is that how low HN has sunk, voting down reality-based statements and voting up complete nonsense?

  I was told 4.1 is working fine.
  - masklinn 15y ago
    As far as I know, 4.1 is still in GM, not released yet, you need a paid developer account to get the GM. In fact, not only is 4.1 not available, 4.0 is gone from MAS.
    - gte910h 15y ago
      I forgot people really used it without the developer program. Good point for those users.
      - napierzaza 15y ago
        As an active developer with apps in the store etc, I don't like upgrading xcode until it's a final release. I've used GMs and betas too many times and then found out I can't submit code built from it. It's really annoying, and I'm not about to test out the buggy xcodes or manage multiple installs. The current 4.x retail releases are buggy enough. So if that's the way it's going to be I will also wait for everything to be released fully.
        gte910h 15y ago
        Oh I'm in the same place (well I'm a 3rd party developer supporting many shops like yours). I've heard from one of the MailChimp guys 4.1 was submitting binaries just fine. I call myself 'An Upgrade Coward'. I'm afraid of Xcode3 breaking even (a couple clients). Probably going to dupe my SSD into the Spinner so I have a working Xcode3 install no matter what. You do know you can install multiple Xcode versions in parallel right?

      It's available now: http://itunes.apple.com/us/app/xcode/id448457090 http://itunes.apple.com/us/app/xcode/id448457090
- mitchty 15y ago
  Just to note, i never bought the xcode 4 package from the app store. After I purchased snow leopard the price changed from $4.99 to free. So while the base os install doesn't have it, it appears as though the naysayers were wrong about them charging for the dev tools. Although I have to go home and update to Lion to be able to download it, it won't let me snag it on my 10.6 system. Just thought i'd throw that out into the wind so people don't think they need to have both bought. Though $5 is pretty miniscule imo.

But gcc does work right?
- blinkingled 15y ago
  Nope - GCC is not to be found after the upgrade. I guess we will have to wait for 4.1 to become available on Mac App Store.

- alsocasey 15y ago
  ...and it's free again? I thought they'd gone to a 4.99$ price for some accounting reason with 4.0?
  - ConstantineXVI 15y ago
    Said accounting reason made it $5 for SL users, but free (or more accurately, "included") with Lion.

Does the latest VMWare Fusion work right?
- blinkingled 15y ago
  Yes 3.1.3 is working fine for me - haven't tested fully but the app starts and my suspended VMs all resume and work fine. When will we be able to install Lion under VMWare - hopefully pretty soon now that the license allows it.

There is a great post on the macports mailing list that identifies and explains some issues installed software might have after upgrading: http://lists.macosforge.org/pipermail/macports-dev/2011-July/015263.html http://lists.macosforge.org/pipermail/macports-dev/2011-July... I got bit by the Libc part, and I bet a lot of homebrew users will be as well. FWIW, on macports svn at least, these issues are resolved.

If you have any kind of Oracle support contract, please put in a ticket. From what I've read, Oracle has adopted 'until paying customers complain enough, we don't even know OS X 10.7 exists' stance on this. Also, knowing how long it took them to get a working x86 client out, I wouldn't hope to use 10.7 for Oracle-related development at least till next year.
ojosilva 15y ago
I'm on SL and I also depend on Oracle 10g, so thanks for the note on the Seg Fault, that would be showstopper moving to Lion. Now, I get the ulimit error on SL too, that's just that your "oracle" user is not authorized to set ulimit that high (it's in your oracle ~/.bashrc). You probably followed the installation instructions from Pythian (http://www.pythian.com/news/1937/quick-install-guide-for-oracle-10g-release-2-on-mac-os-x-leopard-intel/ http://www.pythian.com/news/1937/quick-install-guide-for-ora...), just like I did. If you didn't get that error before, maybe the Lion installation has reset the max processes limit. Here's how to check the current value: ojosilva@snow:~$ sysctl kern.maxprocperuid kern.maxprocperuid: 266 Change it like this (so it matches the ulimit -Su and -Hu values in oracle's .bashrc): sudo sysctl -w kern.maxprocperuid=512 Maybe that will cure your segfault. Read thru the Pythian page and recheck all your sysctl parameters. Let me know how it goes.
