This page explains the way to install ruby-oci8 for Oracle Instant Client.
Look at {file:docs/install-full-client.md} for Oracle Full Client.
Look at {file:docs/install-binary-package.md} for Windows unless you have a special need to compile ruby-oci8 by yourself.
Look at {file:docs/install-on-osx.md} for OS X.
Download the following packages from Oracle Technology Network.
- Instant Client Package - Basic or Basic Lite
- Instant Client Package - SDK
- Instant Client Package - SQL*Plus
Note: use 32-bit packages for 32-bit ruby even though the OS is 64-bit.
Unzip the packages as follows:
mkdir /opt
mkdir /opt/oracle
cd /opt/oracle
unzip path/to/instantclient-basic-OS-VERSION.zip
unzip path/to/instantclient-sdk-OS-VERSION.zip
unzip path/to/instantclient-sqlplus-OS-VERSION.zip
If /opt/oracle/instantclient12_1/libclntsh.so is not found, make a symbolic link to link the library.
cd /opt/oracle/instantclient12_1
ln -s libclntsh.so.12.1 libclntsh.so
Note:
- use libclntsh.sl instead of libclntsh.so on HP-UX PA-RISC.
- skip this step for AIX.
- run
yum install libaio
also on Redhat. - run
apt-get install libaio1
also on Ubuntu.
Set the library search path, whose name depends on the OS, to point to the installed directory.
OS | library search path |
---|---|
Linux | LD_LIBRARY_PATH |
Solaris 32-bit ruby | LD_LIBRARY_PATH_32 or LD_LIBRARY_PATH |
Solaris 64-bit ruby | LD_LIBRARY_PATH_64 or LD_LIBRARY_PATH |
HP-UX PA-RISC 32-bit ruby | SHLIB_PATH |
HP-UX PA-RISC 64-bit ruby | LD_LIBRARY_PATH |
HP-UX IA64 | LD_LIBRARY_PATH |
AIX | LIBPATH |
For example:
$ LD_LIBRARY_PATH=/opt/oracle/instantclient_12_1
$ export LD_LIBRARY_PATH
Though many instant client pages indicate that the environment varialbe
ORACLE_HOME
should be set, it isn't necessary unless Oracle Net
configuration files such as tnsnames.ora
and sqlnet.ora
are in
$ORACLE_HOME/network/admin/
.
Install the downloaded packages as follows:
rpm -i path/to/oracle-instantclient-basic-VERSION-ARCH.rpm
rpm -i path/to/oracle-instantclient-devel-VERSION-ARCH.rpm
rpm -i path/to/oracle-instantclient-sqlplus-VERSION-ARCH.rpm
Set LD_LIBRARY_PATH to point to the directory where libclntsh.so is installed.
For example:
$ LD_LIBRARY_PATH=/usr/lib/oracle/12.1/client/lib
$ export LD_LIBRARY_PATH
Unzip the packages and set PATH
to point to the directory where OCI.DLL
is installed.
If require "ruby-oci8"
raises a load error such as "OCI.DLL: 126(The
specified module could not be found. )", either OCI.DLL
or a DLL depended
by OCI.DLL
could not be found in PATH
.
If OCI.DLL
is surely in PATH
, the missing module is a Visual C++ runtime
library in most cases. You need to install "Microsoft Visual C++ Redistributable
Package" or copy a runtime library to the directory where ruby.exe
resides.
Oracle Version | Package | Runtime Library |
---|---|---|
18.3 | Microsoft Visual C++ 2013 Redistributable Package | MSVCR120.DLL |
12.2.0.x | Microsoft Visual C++ 2013 Redistributable Package | MSVCR120.DLL |
12.1.0.x | Microsoft Visual C++ 2010 Redistributable Package | MSVCR100.DLL |
11.2.0.x | Microsoft Visual C++ 2005 SP1 Redistributable Package (x86, x64) | MSVCR80.DLL(The file version must be 8.0.50727.762.) |
11.1.0.x | No separate redistributable package | MSVCR71.DLL |
10.2.0.x | No separate redistributable package | MSVCR71.DLL |
Run the following command and confirm it works fine. If it doesn't
work well, check LD_LIBRARY_PATH
or PATH.
sqlplus USERNAME/PASSWORD
Run the following command. If it ends with "can't find header files for ruby" or "ruby: no such file to load -- mkmf (LoadError)", you need to install ruby-devel(redhat) or ruby-dev(debian/ubuntu).
ruby -r mkmf -e ""
You need a C compiler and development tools such as make or nmake. Note that they must be same with ones used to compile the ruby. For example, you need Oracle Solaris Studio, not gcc, for ruby compiled by Oracle Solaris Studio.
If you get a problem in the following steps, look at {file:docs/platform-specific-issues.md} and {file:docs/report-installation-issue.md}.
Run the following command.
gem install ruby-oci8
If you get a problem, look at {file:docs/platform-specific-issues.md} and {file:docs/report-installation-issue.md}.
Download the latest tar.gz package from download page.
Note: if you are using Windows and you have no special need to compile it by yourself, look at {file:docs/install-binary-packge.md}.
gzip -dc ruby-oci8-VERSION.tar.gz | tar xvf -
cd ruby-oci8-VERSION
make
make install
note: If you use 'sudo
', use it only when running 'make install
'.
'sudo
' doesn't pass library search path to the executing command for security reasons.
gzip -dc ruby-oci8-VERSION.tar.gz | tar xvf -
cd ruby-oci8-VERSION
nmake
nmake install
