Heroku buildpack for setting up Oracle Instant Client and the LD_LIBRARY_PATH.
In order for this buildpack to execute, it will look for a .oracle.yml file in your app's root. The file can be empty but it must exist.
touch .oracle.yml
You'll need to use multiple buildpacks.
This buildpack will need to be invoked first, followed by your language buildpack.
Heroku now supports configuring multiple buildpacks natively, or you can use the heroku-buildpack-multi buildpack.
Add the following contents to .buildpacks:
https://github.com/luizalabs/oracle-heroku-buildpack
https://github.com/heroku/heroku-buildpack-go
It is sometimes desirable to use tnsnames.ora or sqlnet.ora to configure how Oracle connects to a database or to use sqlnet.ora to configure connection wallets.
The tnsnames.ora and sqlnet.ora files are often located in $ORACLE_HOME/network/admin.
This buildpack will correctly setup $ORACLE_HOME and $TNS_ADMIN to point to $ORACLE_HOME/network/admin.
A location for tnsnames.ora or sqlnet.ora can be configured inside the .oracle.yml file:
cat .oracle.yml
---
tnsnames.ora: config/tnsnames.ora
sqlnet.ora: config/sqlnet.ora
The files will be symlinked into vendor/oracle-instantclient/network/admin
You do not need tnsnames.ora and sqlnet.ora, they're both optional. The buildpack and some other buildpacks will work fine without them.
Although I firmly believe it should work with basically any language, I can only say for the languages I've actually tested :)
If you need this buildpack to work with any other language, feel free to fork this repo and submit a Pull Request ;)
