installing Oracle Instantclient on Mac OS/X without setting environment variables?

Question

Oracle's instructions specify setting DYLD_LIBRARY_PATH. This makes my application dependent on random users' configuration and is very troublesome to set up.

How can I avoid having to set any environment variables?

Answer 1

Oracle's instantclient installation instructions specify that the user set DYLD_LIBRARY_PATH. This is very troublesome to manage for multiple users.

To use the instantclient without setting any environment variables:

Download the instantclient distribution from oracle.com. For doing non-java software development, you will need (assuming Oracle 10.2):

instantclient-basic-macosx-10.2.0.4.0.zip
instantclient-sdk-macosx-10.2.0.4.0.zip
instantclient-sqlplus-macosx-10.2.0.4.0.zip

Unzip the three files. This will give you a directory

instantclient_10_2/

Copy the files to /usr, which is one of the default places the dynamic loader searches.

sudo cp instantclient_10_2/sdk/include/*.h /usr/include
sudo cp instantclient_10_2/sqlplus         /usr/bin
sudo cp instantclient_10_2/*.dylib         /usr/lib

If you use tnsnames.ora, copy it to /etc, which is the default global place the oracle runtime searches.

sudo cp tnsnames.ora /etc

Test with

/usr/bin/sqlplus scott/tiger@myoracle

Answer 2

If your goal is simply to run sqlplus on your MacBook, this might work for you. Remove the DYLD_LIBRARY_PATH environment variable from ~/.bashrc and replace it with an alias:

alias sqlplus="DYLD_LIBRARY_PATH=/Applications/instantclient_11_2 sqlplus"

Answer 3

After much research I found an sustainable solution to this error, that involves editing Apache's launchd configuration .plist file to specify the required DYLD_LIBRARY_PATH, ORACLE_HOME, and LD_LIBRARY_PATH environment variables.
