After manually updating to Java MacOSX10.5 Update 2 two months ago, I noticed something weird with my Firefox. At first, I ignored it, “heh must be a screwed-up page Im trying to open…” But lately, I noticed that most of the pages I am opening with Java applets crashes consistently. So here is the culprit, try to delete java caches if there are any…
Trying to figure out which version of the java applet being used by FF
Deleting the cache.. Go to
/Application/Utilities/Java/ and launch Java Preferences.app or you could seach for “java preferences” in spotlight.
If the problem still persist, I bet we can trim down which java versions to use…
In summary, install Oracle Instant Client and try to run sqlplus. If sqlplus connects to the oracle sid then go ahead and install the rails adapters for oracle. What is important to note here, is to install the oracle-instantclient for the architecture of your machine.. I have tested this on Debian Lenny (i386) and CentOS5 (x64)
1. Download from http://www.oracle.com/technology/software/tech/oci/instantclient/
a. oracle-instantclient-basic-10.2.0.4-1.i386
b. oracle-instantclient-devel-10.2.0.4-1.i386
c. oracle-instantclient-sqlplus-10.2.0.4-1.i386
2. Unzip everything to /opt/oracle/instantclient . You should have something like the ff:
[root@csapp1 instantclient]# ls -la
total 102704
drwxr-xr-x 3 root root 4096 Dec 10 21:54 .
drwxr-xr-x 3 root root 4096 Dec 10 22:03 ..

[root@csapp1 instantclient]#
3. Make a symbolic link for libclntsh.so.10.1 as shown above.
4. Create the Oracle Environment variables
export ORACLE_HOME=/opt/oracle/instantclient
export TNS_ADMIN=$ORACLE_HOME
export LD_LIBRARY_PATH=$ORACLE_HOME:$LD_LIBRARY_PATH
export DYLD_LIBRARY_PATH=$ORACLE_HOME
export PATH=$PATH:$ORACLE_HOME
5. At this point, you should have oracle-instantclient properly installed. You can test by running sqlplus.
[root@csapp1 instantclient]# sqlplus
SQL*Plus: Release 10.2.0.4.0 - Production on Thu Dec 11 11:47:40 2008
Copyright (c) 1982, 2007, Oracle. All Rights Reserved.
NOTE: Sometimes you will get a SEGMENTATION FAULT. If so, try to open a new shell with the environment variables loaded and do an sqlplus in a directory which is not /opt/oracle/instantclient.
6. Install the oracle adapter for rails
7. gem install ruby-oci8
8. gem install oracle_enhanced-adapter –source=”http://gems.rubyonrails.org/”
activerecord-oracle-adapter (1.0.0.9250)
activerecord-oracle_enhanced-adapter (1.1.8)
NOTE: Try to look for the latest gems, the source above is at the time of this writing so it might change.
9. Test using irb
[root@csapp1 instantclient]# irb
irb(main):001:0> require 'rubygems'
=> true
irb(main):002:0> require 'oci8'
=> true
irb(main):003:0>
1. Read http://www.foliosus.com/2008/05/05/connecting-ruby-on-rails-to-oracle-on-an-intel-mac-in-leopard-take-2/
2. Install Oracle Instant Client on Mac.
a. Instant Client Package – Basic: All files required to run OCI, OCCI, and JDBC-OCI applications
- instantclient-basic-macosx-10.2.0.4.0.zip (34,020,719 bytes)
b. *Instant Client Package – SDK: Additional header files and an example makefile for developing Oracle applications with Instant Client
instantclient-sdk-macosx-10.2.0.4.0.zip (603,493 bytes)
OR download the whole bundle (10.2.0.4.zip) with sqlplus installed from my installers.
3. Put this on your sudo vim ~/.bash_profile.
export ORACLE_HOME=/Library/Oracle/instantclient/10.2.0.4
export TNS_ADMIN=$ORACLE_HOME
export LD_LIBRARY_PATH=$ORACLE_HOME
export DYLD_LIBRARY_PATH=$ORACLE_HOME
export PATH=$PATH:$ORACLE_HOME
4. Make a symbolic link
cd /Library/Oracle/instantclient/10.2.0.4
ln -s libclntsh.dylib.10.1 libclntsh.dylib
5. Go to /Library/Oracle/instantclient/10.2.0.4 and edit tnsnames.ora. Point the Oracle SID to the IP where you installed Oracle.
ORCL =
(DESCRIPTION =
(ADDRESS = (PROTOCOL = TCP)(HOST = 192.168.1.155)(PORT = 1521))
(CONNECT_DATA =
(SERVER = DEDICATED)
(SERVICE_NAME = orcl)
)
)
ORCL_2_11 =
(DESCRIPTION =
(ADDRESS = (PROTOCOL = TCP)(HOST = 192.168.2.11)(PORT = 1521))
(CONNECT_DATA =
(SERVER = DEDICATED)
(SERVICE_NAME = orcl)
)
)6. Install the oracle-adapter for rails
sudo gem install activerecord-oracle-adapter --source http://gems.rubyonrails.org
7. In your database.yml file
development:
adapter: oracle
database: orcl
username: youzhu_mobile_dev
password: your_password
or browse the contents of a sample rails project youzhumobile.tar.gz
8. If you ever encounter an encoding problem, then we need to set the NLS_LANG environment variable before running script/server.
# export NLS_LANG=American_America.UTF8
# script/server
or I prefer setting it in the environment.rb
Rails::Initializer.run do |config|
ENV['NLS_LANG']='American_America.UTF8'
# Settings in config/environments/* take precedence over those specified here.
Note: If you don’t know your database encoding, then read this post.
I’ve found this tool which could display my Symbian phone in my Mac using WLAN. It supports BT, WLAN, and USB. So far, WLAN works for me so I sticked with it.
1. Download the software from http://www.digia.com/
2. Install the sis to your Nokia phone. Mine is an E61 so I paired it using BT on my mac.
3. Once installed, fill up the options on your phone… then try to ‘CONNECT’
Connection: TCP/IP
Access Point: Ofc (or Define an access point)
TCP/IP Host: 192.168.1.150 (IP address of my mac)
Fig 1 Trial mode lets you use it for the next two minutes with a big ‘TRIAL’ display on screen.
