OS X Leopard's bare minimum size requirements...

I am planning to have an external Firewire drive which will host a copy of OS X Leopard for emergency situations. I want the drive (or partition) to be as small as possible...
What would that size be, and are there any things I can remove to make it smaller.
I'm not planning to have iLife or International Languages or Developer Tools. Just a bare version of the OS to boot into should OS X fail (on my internal drive).

FWIW, I have successfully booted from Leopard on a hard drive volume as small as the standard DVD capacity (4.7 GB) but I have not fully tested it beyond checking that it will contain & run Disk Utility without apparent problems, & contain & launch (but not necessarily run) most of the other utilities found in the "Utilities" menu of a retail Leopard DVD.
I did not run into any 10% of total disk space partitioning limitations while creating the partition (this was done on drives up to ~500 GB) but I did not install the OS in the normal way, which I'm sure would have created problems.
What I did was to install the OS & the selected utilities on a much larger volume in the normal way, then whittle away at the OS footprint by removing such things as the contents of /System/Library/Printers, all the extra language folders (extension lproj), & anything else I could find not essential for basic operation of the OS or running the utilities. I then cloned this to the tiny volume & performed the above tests. IIRC, the footprint of the OS & the utilities together was something under 2 GB, leaving a bit more than that amount for scratch files.
However, this was done as an experiment to see if I could create an emergency boot DVD for my PPC iMac (the results were less than perfect when this shrunken OS was run from read-only media) & I do not recommend this as worth the effort just to save a few GB of room on a decent sized hard drive.

AD CS Web Enrollment Error - "public key does not meet the minimum size required"

I've installed a standalone root CA and a enterprise subordinate CA in our environment - both are Windows 2008 R2. Everything is working except for Web Enrollment using a custom User template. I duplicated the default User template and choose
2003 Compatible for the new one. I changed the minimum key length to 2048 and set the validity period to 2 years.
We'd like to avoid using the Advanced Certificate Request page, so I modified certrqtp.inc to point to the new template:
Else
' Request types for enterprise
rgAvailReqTypes(0,FIELD_TEMPLATE)="User-custom"
rgAvailReqTypes(0,FIELD_FRIENDLYNAME)=L_UserTemplateCert_Text
rgAvailReqTypes(0,FIELD_CSPLIST)="Microsoft Enhanced Cryptographic Provider v1.0?Microsoft Base Cryptographic Provider v1.0"
rgAvailReqTypes(0,FIELD_CSPLIST2)="Microsoft Base Cryptographic Provider v1.0?Microsoft Enhanced Cryptographic Provider v1.0"
rgAvailReqTypes(0,FIELD_EXPORTABLE)="True"
nAvailReqTypes=1
End If
I also ran into this issue where Web Enrollment jumps straight to the Advanced page if the original User template isn't present on the CA:
http://social.technet.microsoft.com/Forums/en/winserversecurity/thread/9ab514bc-1f9f-424e-b70d-705874d9c623
So I have both User templates loaded on the CA, and I get this error back when attempting a certificate request using IE 8 or 9:
Your certificate request was denied.
Your Request Id is 25. The disposition message is "Denied by Policy Module".
Contact your administrator for further information.
Looking at the CA's Failed Requests section, I see this error:
The public key does not meet the minimum size required by the specified certificate template. 0x80094811 (-2146875375)
I double-checked our custom template and it does specify 2048 as the minimum key size.
Also, when trying with Chrome 11.0, I get an extra option during enrollment asking for a key size (1024 or 2048). When I choose 2048, the certificate request succeeds. I don't get the key size option when using IE, though.
We'd like to get this working with IE if possible. Any ideas?

We had the same error message. The problem turned out to be on the requesting computer, not the server. When we went to renew a cert in IIS on a server it was generating a 1028-bit key request. Since the minimum on the server was set to 2048-bit
the request failed. So, there's two ways to handle this. You can change the certificate template on the server to have a minimum set to 1024-bit or you can have IIS submit a new request for a certificate and choose 2048-bit as the size of the key during the
wizard. We opted to have IIS request a 2048-bit key. The same would apply for whatever computer, device, or software you are using to form the certificate request.
Your message is pretty old, but I am running on the same problem right now. I've added a custom template to select (with 2048) minimum length, but the webpage from the IIS by default provides just 1024-bit. Where can i optimize the IIS to use a 2048-bit
key when requesting the certificate?
When I open the same site with Firefox for example, i got a listed option (Medium / High Strength) to choose for the encryption. It seems that the high strength is >= 2048-bit.

Bare minimum groups required during 'adduser'

i need a working user account where i can mount/unmount,play music, video,blah blah..basically do everything i can as root ,(but obviously not edit system files..) ...what groups do i need to add this user to? ive added this user to some groups, and strangely im able to access my fat32, but not my ntfs partition using this account..(fstab has "defaults,user" for both partitions)
oh and how do i give this user write access to these partitions?(ntfs/vfat and backup reiser partition)?
is there anyway to give user access to pacman? what do groups like bin.adm,tty,daemon do exactly? (manpage?)
thanks very much!

if i remember correctly, umask=000 should be added to fstab ...such as:
/dev/discs/disc0/part2 / reiserfs defaults,user,umask=000 0 0
thats what i tried...however when i try to mount, i get an error ..and a dmesg | tail gives me
ReiserFS: hda2: warning: unknown mount option "umask=000"
ReiserFS: hda2: warning: unknown mount option "umask=000"
ReiserFS: hda2: warning: unknown mount option "umask=000"
so where do i shove umask=000 ??

How can I set the minimum size the location bar should automatically resize to

I have moved all of my navigation buttons, location bar and tabs to be in line. This has been done to maximise the available space on screen.
This works perfectly with two or three tabs open, but once more tabs are opened the location bar automatically shrinks to allow for more tabs and becomes unusable. I want to set the minimum size the location bar should shrink to but I do not know how to do this.

Qfs minimum partition/disk size requirement

I just want to know the minimal requirement of the disk/partition size to create qfs file system?
As qfs separates metadata devices from data devices, what is the minimum size for both to create qfs?
There could be some determination way like creating shortest partitions (in KB’s?) and use them to create qfs.
Please revert with some pointers.

It sounds like people are having different experiences with this issue, here's mine:
When trying to resize partitions without reformatting first, dragging the partition corners worked but didn't allow me to make the second partition smaller than 1/10th the size of the drive. If I used the "size" field to change the second partition, it would reduce, but the first (main) partition would not fill up the rest of the space. If I subsequently tried to change the size of the main partition using either the "size" field or the drag method, it would automatically revert to its previous size.
I decided to go ahead and reformat the drive, after which I was able to create two partitions and resize them freely. I still found that when reducing the size of the second volume, the first did not resize to fill the drive automatically. However, this time I was able to drag the corner of the first volume, increasing its size to fill the drive. Thanks again for your help.

How can I select the minimum size of Elements 10? It won't install due to lack of disk space on C:

I have just purchased and downloaded Elements 10. Can't install it due to insufficient disk space on my C drive. I have enough space on my D drive, but it will not install there, probably because my sustem files are on C drive. The Install wisard does not provide for a selection of the size of Elements 10. Is there a way to select the minimum size? If so, how can I do this?

There is not an option to customize the installation. The system requirements for Photoshop Elements 10 request that you at least have 4 gigabytes free, plus more for installation, how much free space do you have on your C drive?

Final Cut Studio 2 Minimum System Requirements

Help me Obi Wan Kenobi....You're my only hope
I own a Dual 867 MHz Power PC G4 with 1.25 GB of ram and want to purchase Final Cut Studio 2, OS X v10.5 Leopard and Adobe Photoshop CS3. I know Adobe Photoshop CS3 and Leopard are compatible, However what concerns me is Final Cut Studio 2. These are the Minimum System Requirements stated [A Mac computer with a 1.25GHz or faster PowerPC G4 or G5, Intel Core Duo, Intel Core 2 Duo, or Intel Xeon processor] So my question is would Final Cut Studio 2 work efficiently or even at all on my computer? My thinking is with collectively 1734 GHz power it should work, But i could also be delusional. I really would hate to end of buying it only to find put it won't work.
Thanks in advance!!!

If you're LUCKY, you might find a replacement processor card for your MDD Powermac G4 - (ideally dual 1.42GHz) - maybe eBay? - maybe from a Mac "breakers yard"? or someone selling off parts from a blown motherboard example?
It's a drop-in replacement, assuming you're OK with a screwdriver and replacement thermal paste.

JSplitPane resize problem (not a minimum size problem though)

I created a JSplitPane and put a JPanel in both the top and bottom sides. This JSplitPane is in the center section of a BorderLayout of a JFrame. The minimum sizes are set and I can move the divider bar all I want. Instead, I am having trouble resizing the window and having the divider bar becoming shorter. When I resize the window, the width of the images dont become smaller even though they have a minimum size set to a minimal size and there is space in the panels that can be reduced.
Here is the code that I am playing with to get this to work. Any ideas how to get this to work? It works in the SwingSet2 Demo, but there is so much extra junk in there that I cant determine the differences with what I'm doing.
Thanks,
J.R.

Hmm. Ok, that was dumb on my part :-) Sometimes you just need a second set of eyes.
Any Idea why, after I make the fix, the top panel does not resize at all? The bottom one does, but the inner panels of the top do not. I added a second panel to the top and it flowed under the first one panel (p1) as the outter panel (northPanel) resized, but the inner panel stays the same size regardless of how much I narrow the window.

Setting a JLabel's minimum size

Hello,
I have a container with a GridBag layout, and when I resize to a size wher everything fits its fine, but on the bottom of the window I have a JLabel, which can be quite large sometimes. When it is large, its minimum size is the length of the string, so when I resize its container i get some big ugly scroll bars and its contents dont get any smaller, although every other component can be much smaller.
What I would like is for the JLabel to have a minimum size (say 100 pixels) and if the window is resized less than this, introduce scroll bars, otherwise just cut off some of the text, as the label isn't very important!
I have tried loads of different stuff, the most obvious being JLabel.setMinimumSize(new Dimension(100,16)); but nothing seems to have worked, can anyone help?

         public void updateVideoInfo(){
          String str = " ";
          str = " " + videoData.getCurrentCameraProperties().getDeviceName()+" at " + videoData.getWidth() + " by " + videoData.getHeight();
          videoInfo.setText(str);
          int width = this.getSize().width - play.getSize().width - stop.getSize().width;
          videoInfo.setPreferredSize(new Dimension(width-15,16));
     public void validate(){
          updateVideoInfo();
     }I did a quick work arround, which I had tried before but didnt work for some reason... but has now
But this would be awfull to change If i ever add anything in the future so I will look at what you said!

UK iPhone Activation, minimum OS requirements

Sorry to hear some people are experiencing activation problems, I unfortunately have not managed to get that far as although I have studied the iphone features I missed the fact that you need OS 10.4.10 or later (this info is printed on a label attached to the bottom of your iPhone box, but not in the O2 iPhone leaflet handed to me upon entry to their store) to enable the phone to connect to iTunes 7.5, (which I have)! I am presently running Panther 10.3.9. As you are no doubt aware Tiger 10.4.x has now been supercede by Leopard 10.5.x, I doubt this will run on my Quicksilver's (lol) 733mHz processor, which leaves me with the following options:
1, Buy a new mac or 2, Buy Leopard to confirm it won't work with my mac or 3. Try to obtain a second hand copy of Tiger OS 10.4.10. I notice from the postings here that Alley_cat 10.4.9, spaceboyo 10.4.7 and BrendanD 10.4.8 own OS's below 10.4.10, can anyone kindly confirm that they activated there phones using OS's below 10.4.10. If this were the case it would quadruple the apparent OS options open to me at present.
Message was edited by: Shanky

If your Mac does not meet the minimum system requirements for Leopard but it does meet the minimum system requirements for Tiger, I would focus on Tiger which you should be able to purchase at a discounted rate and if the Tiger retail install package does not include 10.4.10, you can use System Update to update from whatever version is included on the install disc to 10.4.10.
I notice from the postings here that Alley_cat 10.4.9, spaceboyo 10.4.7 and BrendanD 10.4.8 own OS's below 10.4.10, can anyone kindly confirm that they activated there phones using OS's below 10.4.10.
This can also mean these posters have updated to 10.4.10 but just haven't changed their OS detail per their discussions preferences to reflect this which many do but if you purchase and install Tiger and the install disc includes 10.4.7 for example, you don't have broadband internet access to download the available 10.4.10 update for installation? Other than that, why else is this a concern?

Minimum system requirements for installing Oracle Application Testing Suite

Hi,
Can anyone tell me what are the minimum system requirements for intalling Oracle Application Testing Suite?
Thanks in Advance

From the release notes (12.1.0.2).
System Requirements
Oracle Application Testing Suite has the following system requirements:
4
3.1 Oracle Functional Testing/OpenScript
Oracle Functional Testing’s OpenScript scripting platform has the following system
requirements:
■ Operating System (32-bit and 64-bit versions): Windows XP, Windows Vista,
Windows 2003, Windows 7, Windows 2008
■ Memory: Minimum 1 GB
■ System: x86, 32-bit or 64-bit processor, 2.6 GHz or faster
■ Disk Space: 4 GB minimum
■ Browser: Internet Explorer 7.x, 8.x., 9.x and Firefox 3.5/3.6, 6.x
3.2 Oracle Load Testing
Oracle Load Testing has the following system requirements:
■ Operating System (32-bit and 64-bit versions): Windows XP, Windows Vista,
Windows 2003, Windows 7, Windows 2008, Windows 2008 R2. Oracle Enterprise
Linux 5.1, 5.2 64, 4u8.
■ Memory: Minimum 2 GB.
■ System: x86, 32-bit or 64-bit processor, 2.6 GHz or faster
■ Disk Space: 10 GB minimum free (at least 3 GB free on the system drive)
■ Browser: Internet Explorer 7.x, 8.x, 9.x, Firefox 3.5/3.6, 6.x
■ Database: Oracle EE 10g or 11g, XE 10g
■ Application Server: Oracle WebLogic 11g (10.3.5.0). Oracle Application Testing
Suite requires the standard WebLogic Server installation (which includes jrocket
jdk.). It does not support generic versions of WebLogic Server installation (such as
those that use wls1035_generic.jar).
■ Oracle Load Testing Agent also supported on Linux 32-bit & 64-bit, in addition to
Windows 32-bit and 64-bit operating systems listed above
Note: These are minimum requirements only and actual
requirements for the Oracle Load Testing Server will vary depending
on the size and configuration of your load test. If you are running
larger load tests, of greater than 1000 Virtual Users, you should
consider deploying Oracle Load Testing on a faster server class
machine with additional RAM recommended.
Note: Oracle recommends running the Oracle Load Testing Server
and Agents on separate systems for production load testing. The
amount of memory required on the Oracle Load Testing Agent
systems may increase based on the number of Virtual Users that will
be assigned to run on each Agent. For more information, visit the
QA/Testing Technology Center on Oracle Technology Network or
contact your Oracle representative.
5
3.3 Oracle Test Manager
Oracle Test Manager has the following system requirements:
■ Operating System (32-bit and 64-bit versions): Windows XP, Windows Vista,
Windows 2003, Windows 7, Windows 2008, Windows 2008 R2. Oracle Enterprise
Linux 5.1, 5.2, 4u8.
■ Memory: Minimum 2 GB.
■ System: x86, 32-bit or 64-bit processor, 2.6 GHz or faster
■ Disk Space: 10 GB minimum free (at least 3 GB free on the system drive)
■ Browser: Internet Explorer 7.x, 8.x, 9.x, Firefox 3.5/3.6, 6.x
■ Database: Oracle EE 10g or 11g, XE 10g
■ Application Server: Oracle WebLogic 11g (10.3.5.0). Oracle Application Testing
Suite requires the standard WebLogic Server installation (which includes jrocket
jdk.). It does not support generic versions of WebLogic Server installation (such as
those that use wls1035_generic.jar).
3.4 Additional Notes
The following are additional notes about system requirements:
■ The ATS installer can automatically install and configure an Oracle 10g Express
Edition (XE) database for use with Oracle Load Testing and Oracle Test Manager.
Although this is useful for demos, for production usage switching to Oracle's 11g
Enterprise Edition database is highly recommended. Oracle 11g Standard Edition
and Oracle 10g EE or SE are also supported.
■ System memory requirements do not take into account other processes that may
be running and using memory on your system, reducing free uncommitted
memory available.
■ When installed on the same machine, Oracle Load Testing and Oracle Test
Manager will run on the same server and use shared system resources. Oracle
Functional Test/OpenScript is a separate application that have its own memory
and CPU requirements.
■ The ATS products will run in 32-bit compatibility mode when installed on 64-bit
operating systems. It is possible for Oracle Application Testing Suite to be installed
on an existing WebLogic server. However, if the pre-installed WebLogic server is
JRockit plus WebLogic (64-bit) environment, some functions in Oracle Application
Testing Suite will not work properly. Oracle Application Testing Suite can be
installed on a 32-bit WebLogic, but not a 64-bit.
■ The legacy Oracle Functional Testing, VB-based scripting platform and associated
components (such as Job Scheduler) are no longer included with the ATS installer
Note: These are minimum requirements only and actual
requirements for Oracle Test Manager will vary depending on the
quantity of test assets stored and number of concurrent users
accessing the application. If you have a large quantity of test cases,
requirements or issues stored and/or are deploying Oracle Test
Manager for a team greater than 10 users, you should consider
deploying Oracle Test Manager on a faster server class machine with
additional RAM recommended.

Center Frame & Lock in Minimum Size

Before setting the main frame visible, many (if not most) Swing applications need to center the frame and lock in a minimum size. These are basic, fundamental steps, but currently they require writing a fair amount of tedious code. This situation could be improved with a couple of convenience methods.
For example:   JFrame frame = new JFame();
   //add UI controls
   frame.pack();
   frame.center();
   frame.setMinimumSize(frame.getCurrentSize()); Any idea why these (or similar) methods are not included in Java? It sure would clean up the top level Swing class in many applications.
- Dem

This situation could be improved with a couple of convenience methods.So create a class called MyFrame and write your own. Everybody has there own idea of whats important and whats not. Thats why you have the ability to extend classes --- to add your own functionality.
have you tried:
frame.setLocationRelativeTo( null );
If your looking for a way to control the minimum size then use add a ComponentListener to the frame. Examples have been posted in the forum.
