1) Modify system preferences by executing this line in a terminal.

defaults write com.apple.systempreferences TMShowUnsupportedNetworkVolumes 1


This will allow you to select the DNS as a backup device when you configure Time Machine.

2) You need to manually create a disk image that Time Machine can understand. The naming convention of this image is key. The name consists of the computers name and mac address of the local eno device without colons. (_.sparsebundle). Easiest way to find out the proper name is to attempt a backup after completing step 1 above. While this is attempting to run, use finder to browse the Volume (Volume_1 in my case) and write down the name of the file its trying to create. The filename will contain .tmp before the .sparebundle. Drop this from the filename and you have the complete name you need to use.

ie: gataca_0021413a0cce.tmp.sparsebundle -> gataca_0021413a0cce.sparsebundle

Open disk utility and create a new disk image on your local drive (you cannot create the image directly on the NFS drive) with the following options:

Format: Spare Bundle Disk Image
Partiions: No Partition Map
Encryption: None
Format: Mac OSX Extended Partition (Journaled)
Size – Maximum Size.. I choose Custom 250GB

After the image is created… manually copy it over to the root of your NFS volume.

3) Kick off the time machine backup and voila!

Now.. be prepared for the caveats of this solution mentioned here.

The /etc/profile was the culprit.  Simply remove the following lines or update them to a much more respectable time interval and restart your X windows.

TMOUT=3600
export TMOUT

Thats one I’ll not forget as its sure a pain when your in development mode with all your terminals set where you want them…. turn away for an hour and find them all closed!

This example is how to install ruby version 1.8.5-p12.

1) Find out the svn revision number of the Portfile by looking in:

http://trac.macosforge.org/projects/macports/log/trunk/dports/lang/ruby/Portfile

In my case it is 21127.

2) Set up a local port repository. In the file /opt/local/etc/macports/sources.conf, add this line before the rsync line:

file:///Users/Shared/dports and create that directory.

3) Install the port into your local repository.

cd /Users/Shared/dports && svn co –revision 21127
http://svn.macports.org/repository/macports/trunk/dports/lang/ruby/
lang/ruby/

4) Run portindex so that ports now finds your new (old) version of ruby.

portindex /Users/Shared/dports

5) Now you should be able to see ruby @1.8.5-p12 in addition to @1.8.6 by running:

port list

6) Install Ruby

sudo port install ruby @1.8.5-p12

You should be up and running now, so to check, run:

ruby -v

You will see something like this:

ruby 1.8.5 (2006-12-25 patchlevel 12) [i686-darwin8.10.1]

Open ScriptEditor and save the following script:

try
set dotVisible to do shell script “defaults read com.apple.finder AppleShowAllFiles”

on error errorMessage number errorNumber
set dotVisible to 0
end try

if dotVisible = “0″ then
do shell script “defaults write com.apple.finder AppleShowAllFiles 1″
else
do shell script “defaults write com.apple.finder AppleShowAllFiles 0″
end if

tell application “Finder” to quit
delay 1

tell application “Finder” to activate
if dotVisible = “0″ then
say “VISIBLE”
else
say “HIDDEN”
end if

1. Copy folder, rename vmx file
2. Edit machine, change hostname
3. Rename vdmk
4. Edit settings and add disk you just renamed as existing disk (remove old one)
5. Start vm and check it works (don’t forget to use newsid)

# Oracle 10g Standard – Fedora 8 Linux Installation Instructions
# Author: Greg Roll
# Date: July 14th, 2008
#
# These instructions have been parsed down to the bare requirements to
# install Oracle 10g Standard on a typical Fedora 8 installation.

## Configuring the Linux Kernel Parameters as per Oracle
## requirements.
##########################################

The Linux kernel is a wonderful thing. Unlike most other *NIX systems,
Linux allows modification of most kernel parameters while the system is
up and running. There’s no need to reboot the system after making
kernel parameter changes. Oracle Database 10g Release 2 requires the
kernel parameter settings shown below. The values given are minimums,
so if your system uses a larger value, don’t change it.

kernel.shmall = 2097152
kernel.shmmax = 536870912
kernel.shmmni = 4096
kernel.sem = 250 32000 100 128
fs.file-max = 65536
net.ipv4.ip_local_port_range = 1024 65000
net.core.rmem_default=262144
net.core.wmem_default=262144
net.core.rmem_max=262144
net.core.wmem_max=262144

On my base fedora 8 installation I found I only had to change a 2 options:

—————-
/etc/sysctl.conf
—————
add:
net.ipv4.ip_local_port_range = 1024 65000
kernel.sem = 250 32000 100 128`

Execute the following command to change the current values of the kernel
parameters:
/sbin/sysctl -p

– Select default inventory directory and ‘oracle’ user.
– Select typical install.
– Select Standard Edition.
– Accept remaining defaults.
– Accept warning on product specific prerequisite checks.
– Select create a database.
– Accept create general purpose database.
– enter dbname ’sample’ sid ’sample’, select Unicode format and enable create database with sample schemas.
– accept defaults until you get to the password definition screen
– define password of ‘password’ for all default accounts (SYS, SYSTEM,
SYSMAN, DBSNMP)
– setup ‘dba’ as privileged system groups.. if were not defined use
default oracle group.

** NOTES **

=======================================
Creating an Oracle Response File for Automated Installs
=======================================
Response
files can be created by running the software in record mode or by
manually editing a sample response file. Here’s a basic demo:

1. Start the OUI with this command to create the response file:
./runInstaller -IgnoreSysPrereqs
-jreLoc /opt/jdk1.6.0_06
-record
-destinationFile /opt/app/oracle/software/uberdev-f8-oracle10.2.0.2-recorded.rsp
2. Make all the selections you want to (source destination, home, home name, products).
3. When you get to the Summary screen, instead of clicking on Install, click on Cancel.

4. Examine the resulting response file created in tmp/recorded.rsp. If
desired, you can manually edit this file as long as you adhere to the
prescribed format (see documentation).
5. Now perform the silent installation like this:
./runInstaller -silent -responseFile /opt/app/oracle/software/uberdev-f8-oracle10.2.0.2-recorded.rsp

The progress of the installation will be reported as the script is being run.

If you have a problem with the installation due to incorrect entries in the response file, the installation will fail with a diagnostic message. Further information can be found in the oraInventory/logs directory. Logs with names in the format installActions-.log and silentInstall.log are created each time the OUI is run using a response file.
