TOracleServer

This class implements an OCCI interface to Oracle data bases.
It uses the instantclient10 software available from Oracle.
To install this client software do:
1) Download Instant Client Packages (4 files) from:
     http://www.oracle.com/technology/software/tech/oci/instantclient/index.html
2) Unzip the files into instantclient10_1 (Mac OS X example here):
unzip instantclient-basic-macosx-10.1.0.3.zip
unzip instantclient-sqlplus-macosx-10.1.0.3.zip
unzip instantclient-sdk-macosx-10.1.0.3.zip
unzip instantclient-jdbc-macosx-10.1.0.3.zip
3) Create two symbolic links for the files that have the version
appended:
ln -s libclntsh.dylib.10.1 libclntsh.dylib
ln -s libocci.dylib.10.1 libocci.dylib
4) Add instantclient10_1 directory to your (DY)LD_LIBRARY_PATH
in your .profile:
export DYLD_LIBRARY_PATH="<pathto>/instantclient10_1"
Use DY only on Mac OS X.
5) If you also want to use the sqlplus command line app add also
export SQLPATH="<pathto>/instantclient10_1"
6) If you want to connect to a remote db server you will also need
to create a tnsname.ora file which describes the local_name for
the remote db servers (at CERN most public machines have this
file in /etc). If it is not in /etc create TNS_ADMIN:
export TNS_ADMIN="<path-to-dir-containing-tnsname.ora>"
7) Test it our with the sqlplus command line app:
sqlplus [username][/password]@<local_name>
or
sqlplus [username][/password]@//[hostname][:port][/database]

ATTENTION: This plugin will not work on Mac OS X / Intel as Oracle
has no intention to release a universal binary of the instantclient
libraries.
